Yes, but unless you perform floating point calculations, you will not RECEIVE incorrect results, so whether they are acceptable or not (of course they aren't) is irrelevant. I do concede, however, that some users may not always be aware of whether they perform floating point calculations or not.

I checked my last 99 calls -- 21 were blocked, 50 were "out of area" and 28 had the calling number or the number and name. This is not particularly great from my perspective. One problem is that GTE serves part of the local calling area, but apparently declines to pass CID to USWest customers. I was hoping the new rules would have a positive influence even though they are about long distance -- hassle factor if nothing else. Can anyone address how the new rules affect cellphone calls? All cellphone calls report "out of area" around here. Presumably this is because the cellphone customer has to pay air charges for all calls. Will they have to pass CID info under the new rules?

Telephone numbers in France are always eight digits for the local number, whether it's a voice line or a fax. The UK is in the process of standardizing the length of phone numbers so that all numbers in any given city will have the same number of digits. This is already true in all the major cities (anything with city code 01x1 or 011x), which have seven-digit numbers. In Germany, they still use a "decimal tree" system. For example, the main switchboard at a hotel where I stayed was XXXX1, but you could dial directly to my room phone by calling XXXX375. Most local numbers in this town were six digits.

They also used the phone a lot, and on weekend nights it would ring and ring, so that I and their other neighbors couldn't get much sleep. The dorm had the standard, wall-mounted dial phones. After several months of this, the guys on the far side of these two got fed up. So one night, when they left the room for a minute, we stuck a one inch square chunk of pencil eraser under the offending phone's switch-hook, then hung up the phone. Result: the phone was off-hook but it didn't show. A few minutes later, one of the phone's owners comes back in, tries to make a call, and gets no dial tone and nothing happens. He tries three or four times. Then he proceeds to take the handset and beat the living s__t out of the phone! It was down for about ten days, and guess who got stuck with the bill!

The question is not that simple. Your question should be something more like "which application do you run on a computer *that uses floating point* *and* from which you would accept a result that is only reliable to 0.001?" The worst error in the Pentium floating-point divide is in the fourth decimal place. There are plenty of applications in which that is adequate precision for everyday use. I'm not saying that anyone with a Pentium should consider keeping the defective chip, only that some people don't need to RUSH OUT to get the replacement RIGHT THIS MINUTE. > Personally, I want a computer at least as consistently accurate as my > $6 pocket calculator.

PAT] Several years ago the Honduran government confiscated the passports of (mostly US) residents of Honduras because they had really big phone bills. The government wanted to be sure they got their money in case the callers had time to leave the country. At least one debtor claimed the calls had been made when she was not at home (or in the country). Some of the calls were international which makes me think that the phone company discovered the fraud themselves but didn't want to take the loss by paying fees for the other end of the connection so they called in the army.

The phone books on CD products I have seen will do this. If you only need to go from name (with or without partial address) to phone number, the entire US fits on a single CD-ROM. Of course, the quality and current- ness of the listings may vary. > [TELECOM Digest Editor's Note: > ...why don't you ask the telco serving the local calling > area for a copy of their directory.

This has been covered somewhat, but to clarify, the policy here in Pac*Bell land is that you get white pages within your LATA for free. If the white pages and yellow pages are in the same book, the yellow pages are free. If the yellow pages are separate, you pay a per-book fee. Thus, the San Francisco YP (2 books) costs twice as much as the Oakland YP (a single book), even though the Oakland YP is almost as large as the combined SF books. As a point of reference, I believe that the only cities in the San Francisco LATA with separate YP's are S.F., Oakland, and San Jose (two books). Of course, all this may change soon with the advances in deregulation, but don't expect the change to favor the consumer in this area.

That's because this line happens to terminate on a switch that they are also using as a LATA tandem.

I did make that point in part. Additionally, and if a particular system is saturated, then some additional fraudulent unpaid traffic might cause legitimate, paid traffic to not get through. > Furthermore, there is the capital investment required to build and > maintain the facilities to provide the additional increment of bandwidth > used by fraudulent calls, in order to provide a satisfactory level of > service to the legitimate subscribers. Yes, but again, how much of the claimed losses are real chargebacks and out of pocket costs, and how much of it is illusory lost profits (some of which might never have occurred). If someone who can't afford cellular service places fraudulent calls, certainly the cellular company loses revenue and perhaps has out of pocket costs, but those calls would never have been made, so the company would never have received the revenue from it. About the only place where lost revenue might be a valid issue is for people who use fraudulent time, not because they can't afford to use the service, but because they cannot afford to have a particular call tracked to a phone issued in their name, again typically because they are involved in the manufacture and sale of unauthorized dried plant residues, and referred to by police and prosecutors as drug dealers. This was the point I probably should have made: that if the cellular companies were actually getting hit for $1 million a day in settlements, I find it likely that they would have pushed for encryption a long time ago. What the $1 million figure probably represents is imaginary lost profits from unbilled fraud, which is a whole different matter altogether. It means that their overall profit margin is less, it does not mean they are actually *out* any money. And this may be the reason cellular companies have essentially either made customers eat most of the fraud, or barely done anything beyond lip service to stop it. ------------------------------ Subject: Re: Cellular Fraud: How Much of it is Real Money?

Well, I don't know Paul's motives, but, one good reason for asking this is in relation to my cellular bill. It's my understanding that cellular carriers can bill back 100% of their fraud losses to subscribers. So, if joe-hacker steals a MIN/ESN and starts making calls (lets assume all local and no LD carrier is involved), the carrier may claim $100 in losses. That $100 is paid for by all of the other subscribers via higher rates. Now, if, as Paul suggests, those losses are just "paper" losses, the carrier is now ahead by $100 and I'm out a bit by higher rates. So, my interest is in how much higher my rates are due to my cellular carrier inflating their losses. How much lower would my rates be if the carrier could only claim their actual cash (as Paul defined) losses? Keep in mind that I'm in the San Francisco/Bay Area and my rates are: $30/month with 5 free minutes; $0.85/min peak and $0.20/off- peak. So, the carriers out here are making a KILLING to start with!

I think Paul raises an interesting point, and I believe that you trivialize it. Nobody denies that cellular fraud happens. I believe, though, that the cellular industry's dollar figures are overinflated, just as the SPA's estimates of software piracy are overinflated, purposely so in a self- serving interest. The key issue is cost versus selling price. The per-minute selling price of a cell call may be, in Paul's case, $.50. But, what is the actual cost of providing that minute to Paul, including depreciation of network infrastructure construction, salaries, software development depreciation, research and development, etc? $.35? Can you really say when a fradulent call is placed that the loss is $.50? Not really. Loss implies that you're depriving the company of something that they otherwise couldn't sell. In a cell call case, its bandwidth. Unless bandwidth is saturated, the "fraudulent" cell call is simply using unoccupied bandwidth that would simply be assigned to a legit call. In this case, the only real "loss" to the carrier is the cost of providing the service (with those depreciated costs, etc.), not the loss of profit from being unable to make a profit by selling that amount of bandwidth. Now, if the network were saturated, and by placing a fradulent cell call you permanently deprived the company of the ability to make a profit off that bandwidth, then you might be able to say the cost of fraud is $.50. I believe that the real reasons industries overstate losses from fraud is to make the problem appear larger than it really is. For example, the recent case of the guy who stole calling card numbers by collecting them through MCI's network software -- they estimated the fraud at what? 25 MILLION dollars? At $1 per minute, that requires 25 million minutes worth of long distance -- or 250,000 people making a 100 minute phone call. Unfortunately, the issue is really techy, and not many people are in a position to question the numbers -- even though, with a little high-school mathematics, running the numbers sometimes makes you stand up and scratch your head with a "wait a minute, something here doesn't juve." And, when people do raise a question, they're critized in the same manner that you address Paul. But, I guess telcos are just honest, trustworthy companies that we shouldn't question at all -- sort of like the attitude we should take with our government too, huh? [TELECOM Digest Editor's Note: I never said the telcos are always honest and I certainly do not believe the government is always honest. But even theives have property rights. You and Paul both bring up the same point about how 'it would not have been sold anyway' ... and while that may or may not be true, my response would be that whether or not it gets sold is my business, not yours. I have some commodity, whatever it is, maybe its capacity on a cellular switch; maybe its a cable television system. I make the statement, 'this is worth X dollars, and that is what you will pay me if you wish to have/use it.' The owner of a product or service is the sole person with the authority to decide what his product or service is 'worth'. If all you and Paul are saying is that people or companies who have things stolen from them occassionally inflate the value of what was stolen for reasons of their own, i.e. insurance payoff, then I would agree with you. Yes, they do that that. If they report what they sold as worth one dollar and what was stolen as worth two dollars (for the same quantity or product, etc) then that is wrong. If they report what was stolen as worth the same amount as that which was sold, then I don't think that is wrong. If you are attempting to trivialize the theft because 'it was not worth as much as they claim' or because 'they would not have sold it anyway' then I contend both those reasons are invalid, simply because what the other person claims is none of your business nor is what he manages to sell or not sell. You cannot trivialize theft based on how out of whack the property owner's ideas about his property's values are with reality. It is still his property. To put it another way, consider a large supermarket in a city like Chicago. Jewel Food Stores tosses a huge amount of perishable stuff out in the dumpster each week when their new stock comes in. Milk with an expiration date only two or three days away. Loaves of bread which have been around awhile or which got banged up and the wrapping slightly sliced open by accident in transit. Entire cartons of eggs where one egg got broken. Boxes of breakfast cereal smashed up in transit. In other words, perfectly good food, but American consumers are picky people. Homeless or other poor people with sophistication or 'street-smarts' know exactly what day, or rather night of the week each Jewel store in the area gets its deliveries and within minutes or maybe an hour what time to go hit those dumpsters and clean them out. Granted, you can't be too picky about variety; you can have a dozen boxes of corn flakes because they threw out the whole carton when the box on top got sliced open accidently by the stock clerk opening the carton, but don't look for any Raisin Bran this week. And in the middle of winter, all those gallon jugs of milk are just fine, but in the middle of the summer if they've been out there in the dumpster more than an hour or so, you don't want them ... otherwise, everything is fine. So since a grocery store is going to toss out all of its perishables when a new order comes in, and since they never manage to sell it all, and since the price tag for the item is probably five times higher than what they paid for it, what real problem is there if someone wants to shoplift a little right from the store? Right? Now substitute cellular carriers and/or telcos and/or software writers. If sneaking something out without paying is cool, then fine. If 'shoplifting' is wrong, then it is wrong.

EPIC obtained the document under the Freedom of Information Act. The guidelines provide an overview of the law surrounding searches, seizures and uses of computer systems and electronic information in criminal and civil cases. They discuss current law and suggest how it may apply to situations involving computers. The draft guidelines were developed by the Justice Department's Computer Crime Division and an informal group of federal agencies known as the Computer Search and Seizure Working Group. Seizing Computers A major portion of the document deals with the seizure of computers. The draft recommends the use of the "independent component doctrine" to determine if a reason can be articulated to seize each separate piece of hardware. Prosecutors are urged to "seize only those pieces of equipment necessary for basic input/output so that the government can successfully execute the warrant." The guidelines reject the theory that because a device is connected to a target computer, it should be seized, stating that "[i]n an era of increased networking, this kind of approach can lead to absurd results." However, the guidelines also note that computers and accessories are frequently incompatible or booby trapped, thus recommending that equipment generally should be seized to ensure that it will work. They recommend that irrelevant material should be returned quickly. "[O]nce the analyst has examined the computer system and data and decided that some items or information need not be kept, the government should return this property as soon as possible." The guidelines suggest that it may be possible to make exact copies of the information on the storage devices and return the computers and data to the suspects if they sign waivers stating that the copy is an exact replica of the original data. On the issue of warrantless seizure and "no-knock warrants," the guidelines note the ease of destroying data. If a suspect is observed destroying data, a warrantless seizure may occur, provided that a warrant is obtained before an actual search can proceed. For "no-knock" warrants, the guidelines caution that more than the mere fact that the evidence can be easily destroyed is required before such a warrant can be issued. "These problems ... are not, standing alone, sufficient to justify dispensing with the knock-and-announce rule." Searching Computers: Generally, warrants are required for searches of computers unless there is a recognized exception to the warrant requirement. The guidelines recommend that law enforcement agents use utility programs to conduct limited searches for specific information, both because the law prefers warrants that are narrowly tailored and for reasons of economy. "The power of the computer allows analysts to design a limited search in other ways as well ... by specific name, words, places ..." For computer systems used by more than one person, the guidelines state that the consent of one user is enough to authorize a search of the entire system, even if each user has a different directory. However, if users have taken "special steps" to protect their privacy, such as using passwords or encryption, a search warrant is necessary. The guidelines suggest that users do not have an expectation of privacy on commercial services and large mainframe systems because users should know that system operators have the technical ability to read all files on such systems. They recommend that the most prudent course is to obtain a warrant, but suggest that in the absence of a warrant prosecutors should argue that "reasonable users will also expect system administrators to be able to access all data on the system." Employees may also have an expectation of privacy in their computers that would prohibit employers from consenting to police searches. Public employees are protected by the Fourth Amendment and searches of their computers are prohibited except for "non-investigatory, work related intrusions" and "investigatory searches for evidence of suspected work-related employee misfeasance." The guidelines discuss the Privacy Protection Act of 1980, which was successfully used in the Steve Jackson Games case against federal agents. They recommend that "before searching any BBS, agents must carefully consider the restrictions of the PPA." Citing the Jackson case, they leave open the question of whether BBS's by themselves are subject to the PPA and state that "the scope of the PPA has been greatly expanded as a practical consequence of the revolution in information technology -- a result which was probably not envisioned by the Act's drafters." Under several DOJ memos issued in 1993, all applications for warrants under the Privacy Protection Act must be approved by a Deputy Assistant Attorney General of the Criminal Division or the supervising DOJ attorney. For computers that contain private electronic mail protected by the Electronic Communications Privacy Act of 1986, prosecutors are advised to inform the judge that private email may be present and avoid reading communications not covered in the warrant. Under the ECPA, a warrant is required for email on a public system that is stored for less than 180 days. If the mail is stored for more than 180 days, law enforcement agents can obtain it either by using a subpoena (if they inform the target beforehand) or by using a warrant without notice. For computers that contain confidential information, the guidelines recommend that forensic experts minimize their examination of irrelevant files. It may also be possible to appoint a special master to search systems containing privileged information. One important section deals with issues relating to encryption and the Fifth Amendment's protection against self-incrimination. The guidelines caution that a grant of limited immunity may be necessary before investi- gators can compel disclosure of an encryption key from a suspect. This suggestion is significant given recent debates over the Clipper Chip and the possibility of mandatory key escrow. Computer Evidence: The draft guidelines also address issues relating to the use of computerized information as evidence. The guidelines note that "this area may become a new battleground for technical experts." They recognize the unique problems of electronic evidence: "it can be created, altered, stored, copied, and moved with unprecedented ease, which creates both problems and opportunities for advocates." The guidelines discuss scenarios where digital photographs can be easily altered without a trace and the potential use of digital signatures to create electronic seals. They also raise questions about the use of computer generated evidence, such as the results of a search failing to locate an electronic tax return in a computer system. An evaluation of the technical processes used will be necessary: "proponents must be prepared to show that the process is reliable." Experts: The DOJ guidelines recommend that experts be used in all computer seizures and searches -- "when in doubt, rely on experts." They provide a list of experts from within government agencies, such as the Electronic Crimes Special Agent program in the Secret Service (with 12 agents at the time of the writing of the guidelines), the Computer Analysis and Response Team of the FBI, and the seized recovery specialists (SERC) in the IRS. The guidelines reveal that "[m]any companies such as IBM and Data General employ some experts solely to assist various law enforcement agencies on search warrants." Other potential experts include local universities and the victims of crimes themselves, although the guidelines caution that there may be potential problems of bias when victims act as experts. Obtaining a Copy of the Guidelines: EPIC, with the cooperation of the Bureau of National Affairs, is making the guidelines available electronically. The document is available via FTP/Gopher/WAIS/listserv from the EPIC online archive at cpsr.org /cpsr/privacy/epic/fed_computer_siezure_guidelines.txt.

Darcos & Company, Silver Spring, MD USA Subject: In the Matter of Callback Services > There ought to be a flag which tells the CO receiving a call if the > call is from within or without the USA, and to reject those calls > which originate in the USA. ("I'm sorry, the number you dialed cannot > be reached from within the USA"). The simplest way would be if the service provider knew what carrier was delivering the call, then they could make arrangements with these carriers to both save them some money and perhaps make some arrangement with them to share the calls coming back. You set up the system so that the carrier sends only a single line from their switch for international calls, and all it has to do is pass down the destination number; they don't even need to supply a voice channel. Calls that come from U.S. Destinations through the carrier are given answer supervision and a message either that the customer is refusing calls from US numbers or that they called an outgoing trunk like. This would then charge the caller the minimum 10c for connecting to the number. Caller ID could be put on the trunk lines; callers that are marked as blocked or local either get a busy signal, an announcement that it's an outgoing only trunk, or just get spiked with an immediate answer and disconnect, causing them to pay for a message unit. If you know which carriers provide overseas service from the countries in question, you can get the major carriers to go along with it in exchange for saving them money since they now no longer pay the 2c termination charge to the local telephone company, and would get outgoing business from the service being generated. But, the point being except where phone rates are still very high, these services aren't of much use because the phone rates for most direct-dial calls have been reduced as a result of the mere existence of arbitrage service resellers. What they would still be good for is bypassing dial restrictions, e.g. from an Arab country to Israel, or other places where direct dial calls are not permitted due to local regulations. And also for making long distance calls that the local authorities have no means to discover the termination number, e.g. a U.S. company without local presence there can tell a southeast asian government to get lost when it demands toll records of someone over there since that government's orders have no validity here, as has been the practice where local banks were typically ordered to provide all credit card transactions of locals. ------------------------------ Date: Fri, 20 Jan 1995 14:00:13 EST From: Paul Robinson Organization: Tansin A.

This is the first word I have heard that the service is back. The story says that C1-Wash-Balt blocked customer calls from New York "while installing antipiracy equipment."

Reply-To: eyegaz1@ibm.net I'm looking for some information on the sharing of long distance fees between long distance carriers and the RBOCs. I've found casual references which indicate that the long distance carriers pay the RBOCs approximately 25% each of the fees collected for long distance calls and keep 50% for themselves. This 25% was referred to as something like "line termination charges". It's the payment to the local carrier for connecting one end of the call. I'm hoping to find an authoritative reference to help me in an argument with a Bell Atlantic engineer. This engineer believes that Bell Atlantic is providing the terminating end of long distance calls to the long distance carriers for free. Anyone have any information on this topic?

TelRoute owed $15-16 million to various companies, including Teleglobe, Fonorola, and Bell Canada to which $3.5 million is owed. TelRoute's specialty was to be its microwave network, and there are reported debts with their Toronto-Buffalo link. Last weekend, Bell Canada switched many of TelRoute's 40 000 customers off equal access, mostly to default to Bell (or in one case I'm familiar with, the line was defaulted to Unitel). After some legal wrangling, Bell is to return TelRoute customers default status back to its customers for now. TelRoute will operate for another three weeks while receiver Peat Marwick Thorne attempts to sell the assets, according to reported terms of agreement between Bell and TelRoute. The TelRoute failure, along with the recent bankruptcy of smaller carrier Northquest Ventures (whose assets were sold to Fonorola), marks a definitive beginning of a shake-out in the Canadian long distance industry, where a surprisingly large number of companies took advantage of the 1992 CRTC decision to open long distance competition. ------------------------------ From: tko161@nwu.edu (Toyoaki Kondo) Subject: American Literature on Multimedia Date: Fri, 20 Jan 1995 00:30:17 -0600 Organization: Northwestern University Does anyone know of any good books or information on how technologies, especially multimedia, will change economic activities of consumers and producers, life styles, political participations, culture, perceptions, and international economic relations.

The 2 GHz spectrum will open up a new realm of personal communications possibilities, bringing Canadians one step closer to accessing the Information Highway. "Canada is on the brink of a new age in personal communications," said Dave Wells, President and Chief Executive Officer, Mobility Canada. "Whether it's using a video phone to call home to the family, or transmitting an X-ray image from an ambulance to a hospital, the 2 GHz spectrum will facilitate the introduction of radical new technology and services that demand considerable bandwidth and are unavailable in today's cellular environment. Essentially, we're going to see a fundamental shift from communication between places, to communication between people, and Mobility Canada is ideally placed to help make that shift happen." Mobility Canada intends to apply for a national license with a minimum capacity of 30 MHz to offer service at 2 GHz so that its growing base of 1.5 million customers across the country can benefit from the range of innovative and complementary services that the additional capability of 2 GHz will make possible. Mobility Canada is also developing a suite of services called Customer First, to ensure that it can meet the changing needs of its customers over time. In preparation for this opportunity Mobility Canada recently launched a comprehensive testing program of potential new PCS technologies -- code Division Multiple Access (CDMA), PCS 1900 and PACS. The trial, which is the only one in the world to include all three major contending technologies, will determine the merits of each and ensure that Mobility Canada can provide the best possible communications solutions. The federal government is scheduled to award licenses for the use of 2 GHz spectrum later this year. If successful, Mobility Canada expects that approximately $1 billion will be invested in developing and implementing new technology and services in the next five years. As a result, up to 1,000 direct new jobs would be created, mostly in the high-skill areas of radio and network engineering and computer software design. A further 2,000 jobs could be created indirectly through an anticipated economic spin-off of up to $2 billion. Mobility Canada recommends that the federal government takes into account the proven track record, business plans and technical and operational abilities of all license applicants, believing preference should be given to those capable of developing and delivering innovative and competent services at this new frequency range. As well, Mobility Canada hopes to see Canadian companies taking the lead in charting this new [news release omitted a line or two here, unfortunately] To date, competition has played a major role in positioning Canada as a world leader in cellular communications. "The provision of PCS at 2 GHz will maintain competition in this emerging telecommunications sector, which is good news for the consumer," said Wells. "And we're confident the federal government will recognize that Mobility Canada is ideally situated to help bring Canadians into the next realm of telecommunications services, and are looking forward to the call for applications." Personal communications services at 2 GHz should offer more than just portable voice communications. While voice will be a key basic service, the spectrum will also enable the transmission of enhanced voice, facsimile data and video services. Some of the possibilities include: mobile medical imaging, mobile video phone, mobile classrooms, virtual field trips, intelligent vehicles and wireless e-mail. PCS will provide a "network of networks" enabling customers to choose services that best meet their individual communications needs. Mobility Canada, a corporation established to deliver quality mobile communications operates Canada's largest cellular and paging networks. Together, Mobility Canada shareholders have invested a record $1.3 billion in wireless technology products and services and directly employ over 3,500 Canadians.

KAHN I, Leonard R. Kahn, declare as follows: 1. I am the President of Kahn Communications, Inc. located at Carle Place, New York. 2. I am the same Leonard R. Kahn who co-authored an article entitled "Enhancement of Telephone Line Performance", which was presented at the National Association of Broadcasters' Engineering Conference held on March 23-26, 1969, in Washington D.C. (hereinafter the NAB article). I am also the same Leonard R. Kahn who is listed as a sole or joint inventor in U.S. Patents Nos. 4,217,661; 3,684,838; and 3,696,298. 3. In addition to the patents set forth in paragraph 2, I am also the sole or joint inventor of over 80 other U.S. patents in the field of electronics and telecommunications. My professional qualifications and achievements are set forth in Attachment A. 4. My above-referenced NAB article was directed to the problem of obtaining high quality speech in the standard telephone network as it was available in 1969. The explicit intention of my 1969 article was to discuss the desirability of restoring, in a telephonic communication system, certain frequencies that were normally attenuated. Specifically, I suggested in my NAB article that the frequencies between 100 Hz and 300 Hz are desirable frequencies to be restored in a telephonic communication system. In the NAB article, I also discussed various devices that could be employed in restoring low frequencies (those between 100 Hz and 300 Hz) in a telephone communication network. 5. Frequencies in the range of between 100 Hz to 300 Hz frequencies are normally attenuated in telephone systems. 6. My NAB article suggested, among other solutions, using an equalizer in a telephone network as a device to accomplish restoration of low frequency speech signals in telephone communication. 7. My NAB article specifically mentions the speech signal associated with a telephone set as the signal to be selectively amplified for more natural speech communication. 8. It was well known, in 1969, when my NAB article was published, that equalization, as referenced in paragraph 6 above, could be accomplished with any of a number of electronic devices known as equalizers or filters. 9. The telephone network was, in 1969, controlled by American Telephone and Telegraph Inc. (AT&T) in a manner which prevented using an equalizer in the straightforward way as suggested in my NAB article. Consequently, it was necessary for me and others to develop complex systems for restoring low frequency signals in the telephone network. 10. The disclosure in U.S Patent No. 5,195,132 relative to the use of an equalizer to restore low frequency speech signals in a telephone network merely reflects the ability of AT&T to arrange their telephone network in accordance with the teaching of my NAB article. In other words, AT&T has modified its network in order to take advantage of the equalizer arrangement suggested in my NAB article. 11. I believe that the disclosure of my NAB article appears to constitute the stated invention in U.S. Patent No. 5,195,132, which provides truer voice transmission of low frequencies. I declare under penalty of perjury, pursuant to the laws of the United States of America, that the foregoing is true and correct. -------------------- John Berryhill 1601 Market St., Suite 720 Philadelphia, PA 19103 ------------------------------ Date: Sat, 21 Jan 1995 00:32:00 -0500 From: dleibold@gvc.com (Dave Leibold) Subject: Which Countries Have Competition (for FAQ Update)? As the FAQ update is under way, one section dealt with the various countries that have introduced telecom competition in some form or other. I've heard of a European Community directive to the effect that its member countries are to open up telecom markets by a given date. Competing local networks are also emerging (including UK, US developments). Information on which countries have introduced, or are about to introduce, competition is welcome, in order to keep the Telecom FAQ comments on this up to date. The current FAQ excerpt on the matter follows: Competition Q: Which countries have competitive long distance service? A: Most countries have a single monopoly telephone company for their local and long distance services. Yet, deregulation of telephone companies and telecommunications in general is a worldwide trend. For better or worse, the international marketplace is demanding more innovation and competition in telecom markets in such areas as electronic mail, fax and data services as well as the long distance, satellite and other network services. The United States has competition in terms of long distance services (i.e. a choice of carriers such as AT&T, MCI, Sprint, Metromedia/ITT, Allnet, ATC). This was established in the early 1980s with the court-ordered dissolution of the Bell System into such pieces as regional local telephone providers, AT&T (long distance) and Bellcore (research, administration of telephone standards, etc.). The UK has a duopoly long distance situation: British Telecom and Mercury can provide long distance services but that could be challenged as other companies wish to provide long distance services. Canada permitted public long distance competition in June 1992. Prior to that, there was limited competition in terms of such things as fax communication services and various long distance/local service resellers, aimed at business interests. Unitel and BCRL/Call-Net were successful in their application to compete. A subsequent appeal of certain aspects of this decision was made by Bell Canada and other existing telephone companies. The result of the appeal was that the decision could stand, and that long distance competition may proceed. New Zealand recently allowed Clear Communications to compete in long distance. Australia now has Optus as a long distance competitor. Japan has competition in international public long distance services. There are initial signs competition in the "local loop", or local exchange services, also. Reports from the UK indicate that there is significant growth in alternative local services, besides the Mercury/BT long distance duopoly (competition of two). Cable companies are touted as alternative local phone companies because of the available capacity on cable feeds, plus the cable industry's conversion to fibre optic and digital technologies. A choice of "dial tone" providers may eventually be available to match the availability of competition in long distance services. ------------------------------ From: glnfoote@freenet.columbus.oh.us (Glenn Foote) Subject: 800 and Caller ID (Comments) Date: 21 Jan 1995 05:23:07 -0500 Organization: The Greater Columbus Freenet > [TELECOM Digest Editor's Note: They are NOT 'paying for the right to > see your phone number'; they are *paying for the phone call*, period. > The person or company or whatever paying for a phone call is entitled > to know where -- to what telephone number -- the connection was extended. > Any 'contract' with telco regards blocking of ID is governed by tariff. > Furthermore, in my phone book where the enhanced custom calling features > are explained in detail, it says plainly 'although you may choose to > block delivery of your number to the telephone you are calling, you may > NOT block delivery on calls to 800 numbers or collect calls.'

Since you wish to not give it, please hang up and dial the > regular number, paying for the call yourself.' PAT] Well, Pat, maybe those who pay for the calls do have a "right" to see the data. But, this "right" does, or at least did, not exist in the tariff for 800 service. And, if it does exist now, you can bet the house, the barn, and the dog, that it is restricted by the words "... where facilities allow". For that matter, only AT&T actually files tariffs with the FCC, the others "publish rates" by choice, not by requirement. Even for AT&T this may end soon. The other companies, who started giving out the calling telephone number, did so (and probably continue) for "marketing" reasons. The "contract(s)" at the local level are different depending on the state and the local telephone company. Also, some (many) phone companies have no provisions for making the tariffs available to the public. For example, although the various PUC's usually require copies of the tariff to be available in "public offices", there is no provision that the Telco must actually have a "public office". So some (many?) the Telco's just did away with "public offices", in favor of "service locations". Everything else is just the same, except no tariff availability. Therefore, if access to the tariff is restricted, by design of the Telcos, the "public" must rely on the assertions of the Telco. Neat, for the Telcos; for the public, it's a problem, and not just in the area of Caller ID. In response to your question/comment: "Are you suggesting because I get this information I 'paid to get your number'? All I paid for was the phone call, which legally means the call *belongs to me*, and I am entitled to know the uses made of my phone when I am charged for those uses. Yes, I am stating that you get this information because you paid to get it. (Incidently, the "you" here refers to anyone who is using a 800 number and gets the caller data, not you personally, Pat.). This data has been made a large part of the marketing effort, and the aftermarket IS software and hardware product area for some time. To claim that you are not paying for the data, as an integral part of the call, is naive. For some time, there was, and still may be, an extra charge for this data when small companies (light traffic) are/is involved. I can point to major companies who have switched carriers just to get this data when it was not available from AT&T. As to "who owns a telephone call", the various courts are in disagreement on that issue as we speak. It may be that a call is "owned" by both parties. There is a lot of history that supports that contention. About "entitled to know": Yes, you are! The right, and ability, to audit Telco bills was a hard won battle. I would be among the first to fight against giving up that right or ability. However, the ability to audit the bill is not as important as the individual privacy/security right of the consumer, nor are they incompatible. The existing technology is more than adequate to provide both. It is very easy to say "pay for it yourself, bozo.". Speaking for myself, and my clients, and I think many others as well, (none of whom are "prima-donnas") paying for it is NOT a problem. Unfortunately, many companies do not allow calls except to 800 numbers, and/or will only "give out" 800 numbers. Increasingly, the reasons for this seem to be the intent to penetrate the privacy/security of the caller, while "hiding" behind a 800 number front which itself cannot be readily identified as to location, company, or purpose. At the risk of repeating myself, It will be interesting to see what will happen when (not, I expect if) this challenge takes place ... makes me kind of glad I retired from the Consulting business ... ;-).

Date: 21 Jan 1995 01:43:59 -0500 [Summary until now: The points raised basically question how much of the claimed cellular phone losses to fraud are "real" versus fiction. i.e., when they claim $20 million in losses, is that actual cost to them, or is based on, say, 20 million minutes at their full retail price of $1/minute]. This overstating of losses is common by Big Business, and by numerous other groups, for the following reasons: a) It gets a lot more publicity; b) It can be used to justify rate increases; c) It can boost insurance payments; d) It can reduce taxes. Let's take a couple or so examples, not necessarily telecom: Police grab 100 pounds of cocaine. Well, umm, maybe they grabbed a bit more, but they show off 100 pounds. They state: "This was worth $1,000/pound on the street, so we just kicked ORGANIZED CRIME for one hundred thousand dollars." However, the actual and replacement cost to the Bad Guys is only $25 plus shipping and handling ... but that wouldn't be newsworthy. Or, let's say you are Mega-tele-sleaze, Inc. You're about to make $100 million in profits. But the IRS will take $50 million of it. So what do you do? Well, for starters, you give $100,000 to the local "take-a-buck political club", but in addition, you tell your accountants to come up with "losses" to offset your profits. Aha!, they say. Let's see ... hmm, there were 10 million minutes of FAKE CALLS!. So we can claim $10 million in losses. Poof, there go $5 million in IRS payments! Or even better ... These calls "would have been" at the Roaming Rate of $5/minute. Wow!. (It's not quite that simple to claim tax losses, but at these figures, it's worth having the tax lawyers work out creative charts). BTW, if I might give an analogy that shows how absurd this can become: Let's say you're a former felon who was given a pardon by an "uindicted co-conspirator", and, in addition to owning a shipyard, you're also the principal shareholder of a major league baseball (remember them?) franchise. You sell tickets to your stadium at $25-$1,000 dollars (depending on location). Lo and behold your security staff finds a dozen kids climbing a tree and watching the game from the outside. You've just had a $1,200 loss ... And, since your payments to the City are based on your profits ...

When a phone is cloned, it is typically used not by Joe Devious to call his office, family, and friends, or to call other mobiles. It is typically used for a day or two by a criminal enterprise to sell long-distance calls, and particularly international calls. The phone gets used for a few days or even hours to sell immigrants the ability to call home in India, Taiwan, Somalia, etc. for say $10 for 10-15 minutes. The airtime costs involved are minimal compared with the long-distance charges. The call-shop operator pockets the cash, then either trashes the phone or re-clones it to a different number. The cellular system incurs actual cash losses equal to the long-distance charges; this may be picked up by the home system, if the cloned number is from a roamer. Whether the serving system or the home system pays, the cellular industry loses big-time cash. Even if a cloned phone is used for local landline calls, there are big losses. If the cloned number is a roamer, the home system picks up losses for the airtime and local connection charge. Many cellular systems charge both per-minute rates for airtime and a local landline charge of 10 cents or so to cover landline interconnection. Whether there's a markup in these or not, the home system that has to pay is socked big-time. Plus there is the cost of doing the roamer verification and record transfer. Roamer verification database administration is expensive; that's why there is typically a premium price paid to roam. These are actual cash losses. The only time there are not actual cash losses is when the cloned phone is used to call only mobile numbers in the same area and neither the cloned number nor the called number is a roamer. It's pretty unlikely that this is a significant proportion of cellular fraud. If a local phone is cloned and only local calls are made, the cellular operator is out of pocket for local interconnection costs and operational overhead costs. If one assumes, as some have asserted, that cellular companies have a 40% profit ratio, then their out-of-pocket costs are 60% of the charges. Think of it this way: If someone broke into your home or tapped into your phone line and made $2000 of calls, your loss would be $2000. If the phone company decided to eat that cost, its loss would be $2000. If the long-distance company decided to eat that cost, its loss would be $2000. Stealing $2000 in phone calls results in $2000 in losses. The same facilities are used to make fraudulent calls as would be used for legitimate calls. The costs are the same, the profits are the same; if the bill isn't paid, those costs are lost and so are the profits. It's not quite the same as software copying, where there are no direct costs to the software company if a kid copies his dad's Autocad. Michael D.

This seems to imply that the +800 country code will contain numbers with only seven digits, yielding a total of no more than ten million international free-phone numbers for the entire world! Given that the North American Numbering Plan alone is already close to running out of seven-digit intra-NANP free-phone numbers, isn't this +800-XXX-XXXX arrangement a bit short-sighted? > If the U.S. position, and U.S. Users Group Position, of grandfathering > existing U.S. 800 numbers is not aggressively supported by U.S. 800 > subscribers, these companies will find they have a 50-50 chance of > winning -- or losing -- their branded number to a lottery, and > competition for the same customers and marketshare in the U.S., and > abroad. Many countries besides the US have intra-national free-phone services. Some even use the same 800 area code! I believe that Ireland, for example, even uses 1-800 as the full prefix, just like the NANP (although I understand that the number that follows is only six, not seven, digits). So why should owners of US 800 numbers (or even NANP 800 numbers -- don't forget Canada and the islands!) be singled out for the privilege of "grandfathering" their existing numbers into the worldwide +800 number space? That doesn't sound very fair to the rest of the world. I think that better schemes are available that could address both these issues (number scarcity and number collision). One simple idea would be to use the format +800--. For example, the US number 1-800-FLOWERS would also be available internationally (assuming the company was willing to pay for incoming international calls) as +800-1-FLOWERS, and a hypothetical Irish number 1-800-FLOWER could be dialed internationally as +800-353-FLOWER. Since each country code would have its own domain within the overall +800 number space, no collisions would be possible. Of course, even this simple scheme could still run into the number scarcity problem, since it presumes only a single free-phone area code for each country (a presumption that will soon break in the NANP, as the 800 NPA fills up and additional free-phone NPAs are allocated). So perhaps the only fool-proof plan is to just use +800- as a prefix to the entire national toll free number, area code and all. Under this method, the US and Irish examples above would become +800 1 800 FLOWERS and +800 353 800 FLOWER, respectively. There are disadvantages with this idea too, of course. One is that all national free-phone numbers that can be mapped transparently into the +800 space must be no longer than - 3 digits, where is the ITU limit on the number of digits that can follow the "+" sign.

Thanks to the Editor and others who have responded so far. While I have both Caller-ID and *69 phone features, my friend (who lives elsewhere) only has *69. She can only trace back the last number that called her. I get a number of ANONYMOUS CALLER calls on my Caller-ID box. If I'm not home when these calls come in, or I've turned the ringer off at night and miss a number of calls, then I can't use *69 to trace these calls. I also can't check to see if the info on the screen changes. A number of these ANNONYMOUS calls are coming from pay phones where someone can press *67 and block their phone number. *69 will not call back these numbers, according to my experience and according to Southern Bell. Raleigh is also ringed by many small towns and several different phone companies: GTE, Centel, Contel, Carolina Telephone/Sprint, etc. Calls made from some of these companies show up as OUT OF AREA calls. Some show the phone number, but will not let you use *69 to redial, so I presume that some of my ANONYMOUS calls that I can't use *69 to call back might be from these phones as well as from some local pay phones. I've back-tracked many of the calls using a 1-900 number and/or various Cross Reference phone directories (at local libraries). 99% of the calls I can trace are coming from individual homes as opposed to apartment complexes, so I don't know how someone could tap or splice into someone else's line in the open out on the street. Thanks for the info so far.

IF THE DOCUMENT THAT IS NOW ON THE TABLE PASSES UNOPPOSED ... The 1 800 FLOWERS vs. 011 800 FLOWERS scenario as I've outlined it, will become reality. THIS COULD HAPPEN AS EARLY AS THIS APRIL. That said, I've tried to answer Bob Goudreau's posting as logically as possible. It gets involved -- I've tried to keep it theaded. I'd written, > Remember, too, that international freephone numbers will *co-exist* > with domestic toll-free numbers in the U.S.. So there will be 1 800 > FLOWERS, and 011 800 FLOWERS, both of which can be called and > advertised within the United States, but which may reach competing > companies! And I'd like to add, What is worse is that the 1-800-AIRWAYS which is British Airways terminates in London now, and 011-800-AIRWAYS could go to American Airlines and terminate in Tulsa. **** For every 800 number dialed the customer will have to determine if it is international or domestic, and understand that "international" doesn't mean it terminates internationally, just that the number belongs to the international number pool. **** Bob went on, > This seems to imply that the +800 country code will contain numbers > with only seven digits, yielding a total of no more than ten million > international free-phone numbers for the entire world! Given that the > North American Numbering Plan alone is already close to running out of > seven-digit intra-NANP free-phone numbers, isn't this +800-XXX-XXXX > arrangement a bit short-sighted? Back to me, Seven or eight digits has not yet been decided. Also there are many options. You can have seven and eight digit. There is a proposal for variable format seven to nine digits. The majority want eight fixed right now so the US could have 1-800-0-xxxxxxx and the rest of the world could have what ever they want. I'd also said, > If the U.S. position, and U.S. Users Group Position, of grandfathering > existing U.S. 800 numbers is not aggressively supported by U.S. 800 > subscribers, these companies will find they have a 50-50 chance of > winning -- or losing -- their branded number to a lottery, and > competition for the same customers and marketshare in the U.S., and > abroad. I'd like to add here, There could be dozens of people who want your number. Having the number now will give you 50/50 chance, but others can obtain the numbers today or next year in other countries (say five other countries) and have a five to one chance better than you even though you have had the number for years. Based on what's currently on the table, it doesn't matter if you've had the number 30 years or 30 minutes to qualify for priority. So, Bob responded, > Many countries besides the US have intra-national free-phone > services. Some even use the same 800 area code! I believe that > Ireland, for example, even uses 1-800 as the full prefix, just like > the NANP (although I understand that the number that follows is only > six, not seven, digits). So why should owners of US 800 numbers (or > even NANP 800 numbers -- don't forget Canada and the islands!) be > singled out for the privilege of "grandfathering" their existing > numbers into the worldwide +800 number space? That doesn't sound very > fair to the rest of the world. > I think that better schemes are available that could address both > these issues (number scarcity and number collision). My response: There are approximately four million U.S. toll-free subscribers, and 150,000 freephone subscribers outside of the U.S. (Some of the 150,000 also are U.S. marketers' international freephone numbers.) U.S. marketers, large and small, corporate and entreprenurial, have invested in, developed and designed the infrastructure for, and nurtured the 800 industry into the marketing powerhouse it is today. Now, I'm a marketing person, and this is important to me. But I don't want to be unfair, or impractical, either. Bob's 100% right here. The question is, why won't the ITU allow alternatives to be discussed? Remember, random numbers mean there's no way to translate from the domestic to international. Bob's scheme is good: +800--. As Bob discusses, the US number 1-800-FLOWERS would also be available internationally (assuming the company was willing to pay for incoming international calls) as +800-1-FLOWERS, and a hypothetical Irish number 1-800-FLOWERS could be dialed internationally as +800-353-FLOWERS. Since each country code would have its own domain within the overall +800 number space, no collisions would be possible. Of course, even this simple scheme could still run into the number scarcity problem, since it presumes only a single free-phone area code for each country. So perhaps the only fool-proof plan is to just use +800- as a prefix to the entire national toll free number, area code and all. Under this method, the US and Irish examples above would become +800 1 800 FLOWERS and +800 353 800 FLOWERS, respectively. There are disadvantages with this idea too, of course. One is that all national free-phone numbers that can be mapped transparently into the +800 space must be no longer than - 3 digits, where is the ITU limit on the number of digits that can follow the "+" sign. Fortunately, itself will soon change (or has just recently changed) from 12 to 15 anyway, so this might not be a problem. But the sheer length of the resulting +800 numbers would be unattractive. Bottom line, we agree that there are better options that merit serious consideration. So the question for U.S. 800 Subscribers to ask their U.S. carriers at the ITU is, why isn't this being discussed?!!! J. Oppenheimer, Producer@Pipeline.com ------------------------------ Date: Mon, 23 Jan 1995 14:46:00 EST From: Hardwire <0003436453@mcimail.com> Subject: MCI Digital 800 Information Contact: David Sutton MCI Business Markets 404/644-NEWS MCI LAUNCHES TOLL-FREE ALTERNATIVE FOR MULTIMEDIA ACCESS First-Ever 800 Digital Service Integrates Voice, Data and Video Redefines the Way Businesses Service and Sell to Customers WASHINGTON, DC, January 23, 1995 -- In its latest extension of the Information Superhighway, MCI today announced at ComNet the first-ever tariffed and commercially available 800 digital service. MCI 800 Digital Service enables users to send and receive simultaneous voice, data and video communications through a single 800 number. Available immediately, MCI 800 Digital Service is ideal for high-speed applications including on-line shopping, remote access to corporate database libraries, customer service, technical support, videoconferencing, document sharing and software distribution. MCI's new service differs from existing data services by transferring connection costs to the service provider, thus encouraging customer access and increasing the likelihood that applications will succeed commercially. "We believe MCI 800 Digital Service will revolutionize the way companies do business," says Brian Brewer, vice president of marketing for MCI Business Markets. "For example, this service will easily allow consumers to call an 800 number to not only order software but also have it simultaneously delivered to their PC. In this same scenario, technical support could then conveniently follow via on-line screen-sharing." Wide Range of Applications By combining the ease of toll-free dialing with the power of high-speed switched data services, MCI is providing users with a highly effective, cost efficient communications link to businesses, consumers and suppliers. Typical applications might include: * On-line Interactive Catalogs -- By dialing a toll-free number, customers can view and purchase a company's products and services directly, dramatically reducing sales cycles. * File Sharing and Collaborative Computing -- Companies can work faster and smarter by enabling workers in different locations to use toll-free desktop videoconferencing and document sharing to edit documents simultaneously. * Toll-Free Access to Corporate Systems -- Companies can connect telecommuters and other office locations to corporate systems, data libraries and LANs. * Multimedia -- Users can combine voice, data and video at speeds of up to 64 Kbps, toll-free. Represents Evolution of Switched Data Services More and more of today's data applications require greater transmission bandwidth and, as a result, are tightly coupled to the underlying technology used to connect to end users. Traditional transmission rates achievable with modems, even high-speed modems, are in many cases unacceptable and degrade an application's quality until it is no longer a viable commercial product. MCI 800 Digital Service offers a solution to this problem by supporting switched data at up to 64 Kbps speeds, six times the speed of a 9.6 modem, toll-free. Digital 800 can originate through a local telephone company's ISDN basic rate interface (BRI) connection or via switched data access. Consumers can call the local phone company to order a BRI line. For consumers already using ISDN BRI or switched data access technology, connecting to a digital 800 application is as simple as dialing an 800 number. Service providers interested in developing digital 800 applications have the option of providing terminating access to their application through a choice of local exchange carrier (LEC) provided switched data, primary rate interface (PRI), BRI or MCI provided PRI terminating access methods. MCI 800 Digital Service is an integral component of MCI's portfolio of 800 services and can be used along with all existing Vision 800 and MCI 800 features. For example, time-of-day routing or percent-allocation routing can be used to ensure that every incoming call is routed to the correct location on the first attempt. MCI reporting tools, Perspective and TrafficView analysis, are also compatible with MCI 800 Digital Service. Pricing for MCI 800 Digital Service will initially reflect standard MCI Vision 800 or MCI 800 voice rates based on the type product platform selected. As with standard voice rates, 800 Digital Service rates will differ based on selection of switched BRI or dedicated PRI termination. All usage will contribute to overall 800 discounts and term commitments. MCI, headquartered in Washington, D.C., has grown from its core long distance business to become the world's third largest carrier of international calling and a premier provider of data communications over the vast Internet computer network. With annual revenues of $12 billion, the company today provides a wide array of consumer and business long distance and local services, data and video communications, on-line information, electronic mail, network management services and communications software. ------------------------------ From: BARRY M.

The company didn't say whether the resulting savings in operator time will lead to layoffs. And it seems as if the company is reducing operator time at the expense of making customers wait on the phone longer while a shortened recorded version of their request is played back to an operator. It is not clear whether the service will also be used for long distance directory assistance requests from outside the Atlanta area. A Southern Bell press release says: "With the company's new DA*Plus service, customers dialing 411 are greeted by the system and then are asked for the name of the city and the person or business whose phone number they need. The system will then record the customer's response. After the information is recorded, DA*Plus automatically trims the silence at the beginning and end of the customer responses and places the call in queue for the next available operator. By eliminating the pauses and silence on each call, the operator hears only the customer's responses, not any hesitation or pauses. The operator then checks for the listing and provides the number requested to the caller just as it is done today. At any time, a caller who wishes to bypass the service can press zero and is immediately connected to an operator." (The press release does not explain how someone with a rotary dial can be connected to an operator.) The company says that customers who have questions or comments about this new service may call 404-780-2323. Attendants will be available to answer questions Monday through Friday from 8:30 a.m. to 4:30 p.m. Journalists can call Lynn Bress of Southern Bell at 404-391-2484.

This area is This sounds familiar. Let me guess, you are using a handheld phone, right? I visited Belgium and Holland last autumn and had similar problems. IMHO the problem is that GSM networks in those countries are not built for handheld phones. Cells are too widely apart and use maximum power allowed for a cell site (20 W?). Your phone sees the cell transmitter and may even show maximum field strength. When you try to _use_ your phone, you'll see that field strength indicator rapidly goes to zero and net connection is lost (that is what happens with Nokia 2110). Handheld phones' 2 W maximum transmitting power is not enough, when cell transmitter is shouting at 20 W! The only decent GSM nets (for handheld phones) are in my opinion in Finland and Sweden (I've used my phone also in UK, the Netherlands, Belgium and Switzerland). Lots of low power cell sites make it work.

(1-800-827-6364) Reply-To: jtleavens@aol.com (JT Leavens) I had my LD service provided to me by AddTel, a LDDS reseller until October 94, when I switched it all to LDDS directly, except for a lonely 800 number that I was hanging on to, but not really using. So I was still getting bills from AddTel for this 800 number with just a few wrong numbers that called the line; no big deal. In December, I took a closer look at my bill and noticed that AddTel was still charging me for the monthly rates for the 800 number they were no longer carrying, and I got suspicious. I then combed through bills since I had switched my service, and found that there were calls that were still being billed by them on that 800 number, even though LDDS was supposedly my provider. Not a lot of calls, mind you, but just a few. Checking my AddTel bills against my LDDS bills I found: *Most of the service was provided by LDDS, as it should have been. *There was an entire week in November when AdTel billed my service and LDDS did not. It was a Monday through Friday, for no explanation I can provide. *There were some days when LDDS and AdTel seemed to fight for my calls, some calls in a day going to one carrier and others going to the other, right after each other with no pattern. *Most upsetting were calls I found on BOTH bills, billed by both companies. There is no doubt that these were the exact same calls. How exactly can this happen? I got a partial explanation from a tech at LDDS who said a "send resporg command to the SDS database" would take care of the routing to LDDS (I assume that's the central 800 database that ensures the proper call routing), but how exactly could the two companies both bill for a single call? And do I have any responsibility to pay AdTel for providing service when I expressly did *not* want them to? Especially since being able to compare identical calls billed side by side proved that I had saved a good bit of money by switching to LDDS. Any ideas from anyone? Thanks in advance!

Sitting here in Boston, I just turned on my Montreal CanTel number; the first thing I tried was to call in via the Montreal number. Usually (e.g. in Pittsburg) calls are properly routed to the phone within five seconds of power-on. Calls continued to no-answer transfer at the Montreal end until I actually attempted to originate a call with the Montreal number here in Boston. Then call delivery started working some but not all of the time. Frequently there was just a fast-busy. None of the feature codes work -- I've tried to use the Ericsson codes (*21* to forward, #21# to cancel) which work when roaming using the CanTel number in Albany, Rochester, Pittsburg, Florida, and San Francisco but not in Utica or Dallas/Fort Worth. I also tried the Cellular One/SWBell feature numbers for Boston, but nothing. At the moment I have turned the phone back off, and calls are no longer going to the no-answer transfer location. That works properly when the phone is turned off in most other places (such as Florida), without the need for any timeout period. It even worked on failed pages; in South Florida I could leave my CanTel number forwarded on no-answer to my NYNEX number; if I got a failed page on the CanTel number I had time to switch to the other NAM and would receive the call on the NYNEX number via BellSouth. But none of this works in Boston; it looks like Boston's NACN connection is either AFU or not completed. /john ------------------------------ End of TELECOM Digest V15 #56 ***************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa17463; 24 Jan 95 20:12 EST Received: by delta.eecs.nwu.edu (4.1/SMI-4.0-proxy) id AA01817; Tue, 24 Jan 95 12:08:10 CST Return-Path: Received: by delta.eecs.nwu.edu (4.1/SMI-4.0-proxy) id AA01802; Tue, 24 Jan 95 12:08:07 CST Date: Tue, 24 Jan 95 12:08:07 CST From: telecom@delta.eecs.nwu.edu (TELECOM Digest (Patrick Townson)) Message-Id: <9501241808.AA01802@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: TELECOM Digest V15 #57 TELECOM Digest Tue, 24 Jan 95 12:08:00 CST Volume 15 : Issue 57 Inside This Issue: Editor: Patrick A.

One was Motorola's proposed Iridium system. I have not heard anything about these in the last few months. Have we reached some sort of watershed. What's the news?

Cell One/NY (00025) has added cellular coverage in the Lincoln Tunnel ("Temp" I-495 between NY and NJ), providing through service from one end to the other. Callers can now place and receive calls, or continue on existing calls uninterrupted. A very productive addition considering how backed up traffic can be there! No service yet (that I have heard of) in the Holland Tunnel (was going to be I-78 when they still built new roads in NYC ...). NYNEX is dead in the Lincoln Tunnel. It seems that most of the tunnels in the northeast are now covered: -In Boston, CO/Boston (and NYNEX/Boston?) has excellent coverage in the Callahan and Sumner Tunnels. -In NYC, the Lincoln Tunnel is now covered by CO/NY. -In Baltimore, both tunnels are covered quite well by CO/Baltimore-DC and BAMS/Baltimore-DC. -In DC, the "tunnels" under the Mall (I-395, was to be I-95) and the I-195 (?) tunnels both have excellent coverage with both carriers.

Organization: ADC Kentrox - Portland, Oregon Date: Mon, 23 Jan 1995 19:13:52 GMT We've had reports of a new type of RJ-48 jack being used in the Nynex service area for T-1 service. Can anyone familiar with Nynex practices and materials help us out? The traditional RJ-48X jack provides shorting bars which loop transmit (pins 4 and 5) to receive (pins 1 and 2) when the customer's plug is withdrawn. The RJ-48X jacks we're familiar with do this by means of a small stationary printed circuit board upon which the "fingers" of the jack rest when the plug is withdrawn. The reports we're getting describe a jack which has some sort of mechanism that is moved off of its shorted position by contact with the flat areas of the plug adjacent to the outside pins (1 and 8). The problem is that some vendors' RJ-48 jacks are solid in this area and some have grooves that look as if they could accomodate a 9th and 10th contact. These grooves apparently prevent the shorting mechanism from releasing. If anyone is familiar with these jacks, we would appreciate your help. We need: 1. The name of the manufacturer of these jacks. 2. The part number of these jacks. 3. The spec, if any to which they are designed. 4. A sample of the jack itself, if possible.

Edwin chen@leland.stanford.edu [TELECOM Digest Editor's Note: Edwin, are you seeking information or trying to slip in a sales pitch? ... by the merest coincidence of course (of course!) this very topic consumed a great deal of bandwidth in a couple other telecom newsgroups in recent weeks. Some respondents were very suspicious of the program. Wasn't there some discussion of having to make payment by courier service rather than regular mail? Weren't there a couple other questions raised but never really answered about the firm? If you are getting truly unlimited service for $149 per month, with no gimmicks and no fraud (there was a hint of that in the other discussion, wasn't there?) then I would say you probably have the best deal you are going to find if your usage otherwise would total at least $200-250 or more per month through more 'conventional' carriers. If all you are using normally is $100-150 per month, then its just a dollar for dollar trade, with your twenty minute per call restriction and (I think I read) a limit of one call at a time. Since all the major and well-established carriers will cut various deals with large users, even if your 'normal' usage came to $200 or so per month, you would not be getting any significant savings. I don't know of any instances where the major carriers will give a forty or fifty percent discount, so if your bill would usually be in excess of $250-300 per month, then I would say you have a good bargain. But at the going rate per minute, if you are on the phone long distance that much time, you must be on the phone for something or other for several hours per day. Well ... I guess I am also, now that I think about it. I am on the dialup to Northwestern University for several hours each day, but I don't know how I could live with the twenty minute per call limit.

The white area shows the limits of the white pages covered by that book. In the case of the Los Angeles area, there can -- and will be -- holes in that area because pieces will be covered by different telephone companies there. The yellow area is the maximum area that yellow pages for that area will cover, and again, may have holes. > Are all the listed numbers in the white area supposed to be in > white pages of the phone book? They don't seem to be. Let's not forget that people can have nonpublished numbers that you can still get from directory assistance, and in California, 40% of the telephone subscribers are unlisted which means they don't show up anywhere. > The GTE phone books where I live (near LA) show the parts of the > puzzle covering their turf, but the PacBell phone books don't. Also, > GTE has "neighborhood" directories that invade PacBell's turf. A > "neighborhood" directory is typically much thinner than a real > directory. A "neighborhood" directory is a private directory sold to companies for a lot less money than additional Yellow Pages listings in the phone book from the telephone company, but listings in those still have to be purchased separately, and this costs extra money, so the secondary books typically tend to be thinner. Also, they usually cover smaller areas (so the salesman can collect more commissions from those who want good coverage by selling them listings in multiple books). > Why? What is going on? Directory advertising means money, and as long as they can sell advertising to people, they will continue to publish them. I'm surprised we haven't seen fringe directories, say the "National Gay & Lesbian Yellow Pages" for businesses that want to solicit to those groups. Or this could be used for people to run personal ads. :) (I would have thought this was silly until I discovered American Express was advertising it's double signature travelers checks in gay-oriented newspapers and showing two men in the picture). How about the "National Amputee Yellow Pages" where companies that specialize in services for people with missing limbs can look. Etc. If you can figure out something that you can sell advertising for, chances are someone, somewhere, will create a magazine, directory or catalog to cash in on it. You or I may think it's wierd or unusual, but 50% of a niche market can be a lot more revenue than 1/2 of 1% of a major national one. [TELECOM Digest Editor's Note: A few responses are in order. First of all, in large cities like Chicago, there *are* the equivilent of 'gay and lesbian yellow pages' directories. One published covering the Chicago area is called 'OUT'. Next point: telco itself also publishes 'neighborhood phone directories'. For instance, there are a couple hundred phone books covering the greater Chicago area all of which are published by DonTech, which is the recent name for the Ameritech subsidiary formerly known as R.R. Donnelly and Company. There is the large Chicago alphabetical directory and corresponding two-part Yellow Pages. There are about thirty 'neighborhood' books, with their own yellow pages in the back of the book. These are just subsets of the larger book, extracted by address groupings within a given area of the city, and all published by telco. There are eight 'regional books' for the suburbs, broken down by near north, far north, northwest, near west, far west, southwest, south, and 'Calumet Region' (northern Indiana suburbs). Each of these books contains a couple dozen suburban communities, and each regional book is roughly equivilent to the Chicago White Pages for their particular area. Just as the large Chicago book has about thirty smaller 'neighborhood' books based on it, each of the eight regional books has its own collection of smaller 'neighborhood' (or actually, suburban town) books, usually with two or three villages or towns grouped together. For example in Skokie where I am, we are in the near north suburban regional book (white pages only, no yellow pages, but with alpha listings divided into two categories, business and residential), and we are in the book known as 'Skokie/Evanston/Morton Grove' with addresses defaulting to Skokie unless 'MG' or 'EV' is shown following the address. These little community books also have yellow pages. The other telco-published directory comes from Centel. That phone company serves Des Plaines and Park Ridge in their entireity. It also serves a small portion of Chicago on the northwest side, along with bits of Niles, Illinois and bits of the Ohare Airport complex not considered within the city of Chicago for whatever reason. They publish their own book for those towns, and Centel even has its own book for that part of Chicago it serves, entitled 'Chicago-Newscastle' for the central office involved. But all of Centel's listings also show up in the Illinois Bell/Ameritech/DonTech books in routine alphabetical order as well with no mention made they are really Centel numbers. Finally, although Lincolnwood, Harwood Heights, Norridge and unincorporated Norwood Park Township are suburbs and not part of Chicago, for whatever reason (I guess, since they are mostly surrounded by Chicago), their listings appear in the large white pages book for the city itself. There are a couple of independent (non-telco) directory publishers serving this area, and there is even something called the 'Sprint Yellow Pages' which I presume comes from that company. It seems like every few days a new book or books is dropped on our doorstep in a plastic bag. Some of these independent directories are rife with errors; some so obvious even an untrained eye like mine can scan through the pages and find mistakes. Oh yeah -- DonTech also publishes numerous 'crisscross' or cross reference directories for the entire area. I think there are about six or eight volumes of those.

Glenn L Foote ...... glnfoote@freenet.columbus.oh.us [TELECOM Digest Editor's Note: The FCC said something recently about telcos being required to pass Caller-ID between themselves on an interstate basis beginning this year. I think the caller can still explicitly block his ID if desired with *67, but the caller cannot get careless about this and assume that since it is 'long distance' the other end won't get his ID by default. In other words, no more (or very little) 'out of area' messages. It is not so much that they 'removed blocking' as it is they said ID had to be passed along where interstate calls was concerned. I routinely now get the ID of parties calling me from all over the USA -- even California. There are still some 'out of areas' but they are getting to be fewer and fewer. And it is always worth repeating to the newbies here and others: no matter how many times you press *67 or how big of a tantrum you have on the phone with a telco service rep and her supervisor and the office manager and the president of the telco and the chairman of the board, when you dial an 800 number (or a 500/700 number using a reverse charge pin or you ask for the charges to be reversed to the called party) your number *WILL* be available to the person you are calling.

Your best bet is to magnetic mount on the roof, right in the middle so the antenna has a grounding plane. Do not get a 5dB antenna. That's over kill in a metro area. It'll over shoot the towers. Best one's to try out is a 3dB, or a 1/4 wave antenna. Or maybe all you need is the unigain antenna. This setup should help quite a bit.

Little off topic, but the bug does not affect system performance. CPU bottlenecks are only caused by how your system was designed (your motherboard). The problem has been solved.

As background, I am one of the people representing AT&T in UIFN work in the US and at Study Group 2 in the ITU-T. I'd like to pass on two pieces of information. First, in response to: J. Oppenheimer, Producer@Pipeline.com who wrote: > Bottom line, we agree that there are better options that merit serious > consideration. > So the question for U.S. 800 Subscribers to ask their U.S. carriers > at the ITU is, why isn't this being discussed?!!! I've included a time line we've kept as to what the format proposals and discussions have been at the ITU-T Study Group 2 level. Most of this will look familiar to those who have read this thread thus far. After that is an extract from the current DRAFT recommendation E.169, specifically dealing with the case of duplicate requests for the same UIFN. As background, the procedures specify first-come, first-served. At the start-up of UIFN assignments, a window of a specified number of days is treated as the same time to allow applicants to get their initial requests in and be treated as if they all arrived simultaneously. I'd also like to note that the U.S. standards process is an open process. The State Department Study Group A coordinates the positions and contributions going forward to ITU-T Study Group 2. An Ad Hoc committee on Numbering meets more frequently to discuss the issues in depth. We've had customer participation from associations and from individual companies interested in this issue, and that participation has been welcome and encouraged. We've also encouraged multi-national customers to contact thier carriers in other countries to make their views known. Also, this process is a contribution driven process. Those with views are most effective when documenting those views, and making specific proposals as to positions or text to be deleted, added, or altered. All contributions to the Ad Hoc or Study Group A meetings are discussed. I hope this is helpful. John Carl Brown --------------------------------------------- Universal International Freephone Numbering Timeline Current study period June 1993 through May 1996 GENEVA - JUNE 1993 Study Group 2 (numbering experts group) accepted a liaison from Study Group 1 (service description experts), recognizing the need for IFS to have an easily recognizable universal global code, develop a numbering plan for this Universal IFS Number. The following is an excerpt from that liaison: ... a universal freephone number as a service feature of IFS. This feature allows a customer to be assigned a specific IFS number that would be the same throughout the world, while calls to this number, if required, can be routed to different destination accesses depending on country or point of origin. ... the legitimacy of this IFS service feature, noting increasing customer demand for such a capability, and the significantly increased use of the IFS that would result from the provision of a universal IFS number. Recognizing the current North American 800 Service code has world wide customer identification, country code "800" was reserved as the Universal Freephone indicator. A list of attributes for the numbering plan includes, but is not exclusive of: the plan should provide a substantial capacity, and should be easily recognizable.

Results of these proposals categorized the numbering formats into three groups (fixed, variable/reusable, and variable non-reusable). Further attributes agreed to: The numbers should be portable so the customers can retain their number and change their service provider. The plan should be stable and support growth. MADRID - JANUARY 1994 The debate over the UFN format continued, discussing as many as seven different formats. Preserving national freephone numbers within a UFN as well as the administration of the numbers compounded the problem of agreeing to any specific format. It was suggested at this meeting that a neutral body administer these numbers, under consideration is the ITU. All participants were asked to only consider two formats for the next meeting; a variable six to eight digit length, or a fixed eight digit length. GENEVA - MARCH 1994 Source: AT&T 800 XXXXXXX (7 digits) Existing customer's seven digit freephone subscriber numbers are retained as the subscriber number of the UFNs for one year. After the one year period all seven digit freephone subscriber numbers that are not identified to be used as the subscriber number of UFNs for IFS would be included in the UFN resource pool and available for assignment. Source: Remaining Representative: 800 XXXXXXXX (8 digits) One representative (Sweden) conclusion for supporting eight digits: Since the seven digit fixed format doesn't give all the countries existing countries customers the ability to either retain or embed their existing numbers in an equal and fair basis, and doesn't offer any way of expanding the capacity, the only alternative left is the eight digit fixed format. A fixed format was agreed to with bracketed text for seven or eight digits. Work will continue on administrative issues. OSLO - JULY 1994 Approximately 30 countries presented a single contribution supporting an eight digit fixed format. The US was the only representative supporting a seven digit format. Acknowledging the need to continue the work, the U.S., restated their support for seven digits but agreed to work on the remaining portions of the document, assuming the format would be eight digits in length. Start up procedures, in particular conflict resolution procedures for that time were debated. The representative from the U.K., offered partitioning the subscriber number with specific leading digits: 800 1Z XXXXXX For further study 800 2Y XXXXXX 6 digit subscriber number migration space 800 3Y XXXXXX 6 digit subscriber number migration space 800 4 XXXXXXX 7 digit subscriber number migration space 800 5Y YYYYYY New 8 digit number 800 6Y YYYYYY " " 800 7Y YYYYYY " " 800 8Z ZZZZZZ For further study 800 9Z ZZZZZZ For further study 800 0Z ZZZZZZ For further study WASHINGTON DC - OCTOBER 1994 (joint experts editing team) To try to progress the work, a small group of representatives met to edit the document. This will be presented to the next meeting in Geneva, December 1994. This document assumes a fixed eight digit subscriber number. The numbers will be assigned on a first come first served basis with no preallocation of space. Priority will be given to those subscribers who are embedding their existing freephone subscriber number. Embedding can be requested by adding trailing or leading filler digits. For example: Subscriber A's 7 digit existing number is 234 5678 Embedding by adding leading filler digits: UIFN requested could be 800 X2345678 Embedding by adding trailing filler digits: UIFN requested could be 800 2345678X When two or more applicants request the same number, the Registrar will communicate with the applicants and notify them of the duplicate request and attempt to resolve the duplicate request by having the applicant(s) change their filler digits to eliminate the duplication. GENEVA - DECEMBER 1994 The meeting agreed that the edited output of TD 1/2-127 (Washington meeting) should be used to advance the work at the meeting and to incorporate any points it thought as appropriate from E.IFSNUM. The TSB had assigned temporary number E.169 to E.IFSNUM. ---------------------------------------------- end of timeline Extract from draft recommendation E.169: Annex A A1 Duplicate Requests 1 The purpose of these procedures is to resolve UIFN conflicts, e.g., when more than one applicant applies for the same UIFN at the same time. 1a) The registrar should advise only the involved applicants when problems are identified, and provide advice to them and cooperate in problem resolution. 1b) The registrar shall give priority to the applicants embedding their subscriber's existing entire national FSN [Freephone Subscriber Number], this is known as priority assignment. 2 The specific procedures are: 2a) The applicant can only request and receive priority assignment based on the intent to embed the entire existing FSN. The embedding can only be requested by adding trailing or leading filler digits to the entire existing FSN, in the manner illustrated below. For example: Subscriber A 7-digit FSN is 234 5678 Embedding by adding leading filler digit: UIFN request 800 X2345678 Embedding by adding trailing filler digit: UIFN request 800 2345678X Subscriber B 6-digit FSN is 654 321 Embedding by adding leading filler digits: UIFN request 800 XX654321 Embedding by adding trailing filler digits: UIFN request 800 654321XX Embedding by adding one leading and one trailing digits: UIFN request 800 X654321X where X = 0-9 Similar principles apply for IFS subscribers with fewer than 6 digit FSNs 2b) When two or more applicants request the same UIFN, and only one of applicants request a priority assignment, the registrar will assign the UIFN to the applicant which requested priority assignment. The registrar will then assign the stated alternative choices, or solicit alternative choices, to the other applicants. 2c) When two or more applicants requesting the same UIFN based on their entire FSN, request priority assignment, the registrar will communicate with the applicants and notify them of the duplicate request and attempt to resolve the duplicate request by having the applicant(s) change their filler digits to eliminate the duplication. During this procedure, the registrar will inform the applicants that they are in contention for their selected UIFN. Identities of other applicants involved in the contention will only be divulged with the consent of all the involved applicants, for the purpose of resolving the contention. 2d) When two or more applicants requested the same UIFN, and none have requested priority assignment, the registrar will communicate with the applicants and notify them of the duplicate request and attempt to resolve the duplicate request by having the applicant(s) choose an alternate UIFN if applicable. During this procedure, the registrar will inform the applicants that they are in contention for their selected UIFN. Identities of other applicants involved in the contention will only be divulged with the consent of all the involved applicants, for the purpose of resolving the contention. 2e) Absent agreement to resolve the duplicate request with the applicants the registrar will, after 15 days, do a random selection to resolve duplicate request. The applicants not receiving the number will be assigned one of their alternate choices or the registrar will solicit another choice, if not provided. -------------------------------------------- End of E.169 extract. ------------------------------ Date: Tue, 24 Jan 1995 12:04:57 EST From: Greg Monti Subject: Chicago 630 Plan - Such As It Is A story in the January 23, 1995, issue of {Communications Daily} says that an Illinois Commerce Commission hearing examiner has "endorsed" a plan to create the 630 area code to relieve 708. Presumably, the endorsed plan is the overlay that has already been discussed because the story notes that it wouldn't require existing customers to change their telephone numbers. The story then says, cryptically, that the plan also would "create 'permissive and mandatory dialing arrangements' that wouldn't jeopardize new competitors". And that the City of Chicago "opposed the stipulation on ground that eleven-digit rather than seven-digit dialing requirement was 'onerous' and might predetermine similar fate for 312 area code where customers are used to seven-digit intraLATA calls." --------------------- Monti interprets shakily: Isn't this a little late for "endorsements" with the new code already created? Callers between the three Chicagoland area codes will need to dial eleven digits to reach local subscribers in the other two codes, which is the same as now. Allowing seen digit dialing between 312 and 630 would require that the prefix codes used in 630 not be usable in 312, which would exhaust 312 faster. Allowing seven digit dialing *within* your own area code may be -- or may not be -- permitted. Others who'd like to try their hands at translating this story into English are welcome to do so.

Weil" To: otr@airwaves.chi.il.us Subject: PaperMate Ball Point Pens I was listening to a 1953 episode of The Hall Of Fantasy last night, and there was an ad for Philco TVs being sold through a store called CET in Rockford, Illinois. The main store was in Chicago. The pitchman promised a FREE PaperMate Ball Point pen, without obligation, to anyone who called the store to set up an appointment for a salesman to visit your home to give you info about Philco TV's. The pitchman said the new pen was "sweeping the nation", ... "a $1.59 value!" For those interested, and maybe the offer still holds (hee hee), the number for the store in Chicago was MOhawk 4-4100. The number for the store in Rockford was curiously 8-22-47. I'm too young to know anything about 5 digit phone numbers. Is that how it was back then in small cities? I'd also be curious to know if anyone remembers this store and if it's still around. (I could call directory assistance myself, but this is more fun.) I'd also like to know if a ball point pen was such a novelty that you'd let a salesman into your home for a free one, or was it the TV, or both? Andrew C. Green (312) 266-4431 Datalogics, Inc. Internet: acg@dlogics.com 441 W. Huron Chicago, IL 60610-3498 FAX: (312) 266-4473 [TELECOM Digest Editor's Note: CET = Central Electric Television. They were a big distributor of television sets in the 1950's here. Both television and 'throw away when used' ball-point pens were new and unusual items in those years. Pocket calculators had never been heard of. When I was in high school, 1956-60, the school gave us the 'option' of using ball-point pens instead of fountain pens, although the latter were preferred. Desks in school classrooms had a little holder near the top for the bottle of ink used to fill the little rubber bladders inside fountain pens. The schools and all progessive educators of the era preferred that children use fountain pens, as it was believed they helped develop better penmanship. Television sets were becoming more common by then; maybe a third to half the households in the USA had one, mainly if the owner lived in a large city where television stations could be received. A few people had television sets as early as 1946-47. Our family got one in 1949; it had a two or three inch screen that was totally round with a very large magnifying glass attachment which hooked on the front of it. It was in fact a Philco (for anyone interested, that was our friends at Phillips) and stood in a large cabinet about four feet tall and two feet wide. We got three channels on it, one being WGN Channel 9; and there were two others. MOHawk was a central office in Chicago from shortly after the turn of the century. Now it is known as 312-664, and then as now serves the near-north side of the central Chicago area. In addition to CET, which was located on Chicago Avenue at Halsted Street (now for thirty plus years the site of a housing complex operated by the Chicago Housing Authority known as 'Cabrini-Green Homes'), other notable subscribers on the MOHawk exchange included the Chicago Rapid Transit Company, MOHawk-4-7200 for administrative offices, (7000 for transit information) which in 1947 became the Chicago Transit Authority. They still use 312-664-7200 for Transit Authority offices, but 836-7000 for general transit information throughout northern Illinois in a consolidated phone room operated jointly by all the commuter railroads and local/suburban bus lines. Since CRT Company had that number as of about 1921, I guess that makes 664-7200 one of the longest continuing subscribers on the same number; 74 years of it now. Five digit numbers were common in communities which had automatic dialing systems in those days but only one exchange in the community. Since the exchange name was always the same, it was assumed when dialing. In your example you parsed the number incorrectly. It was 8-2247, or to be complete about it, ROckford-8-2247. Gary, Indiana had the same kind of setup. The company town named after William Gary, president of US Steel at the turn of the century had several exchanges, but they were all TUrner, as in TUrner 2,3,4,5,6 or 7. Therefore five-digit dialing (or five digit asking of the operator, prior to 1955) was allowed in the form of 2-xxxx through 7-xxxx. Someone once asked who was Turner ... he was a vice-president of US Steel about the same time, and highly revered for his contributions to the civic life in Gary. In the early 1920's, the United States Supreme Court required US Steel to divest itself of the Gary Municipal Corporation. But some things did not change; the town name was retained and the phone exchanges continued to be Turner. Today they are 219-882 ... 887. Why yes ... ballpoint pens were quite a novelty in 1953, and the better quality ones were quite expensive, in the $7-10 range. 'Cheaper' ones, like the free gifts from Central Electric Television ranged in price from a dollar to a dollar and a half. But don't worry, they made out like bandits since the television sets sold for several hundred dollars each; three-inch round screens which looked like oscilliscopes. CET had as a commercial, a jolly man singing "Cee Eee Tee .... for television! (and concluding) Mohawk four, four one hundred!" They've been out of business for about thirty years now.

Originally, the incoming calls go to the cellular phone that have the small card inserted. If you want to change that, you insert either one of the cards in a cellular phone and use a code ("333") to switch incoming calls from the card now receiving them to the other card. ------------------------------ From: tholome@dialup.francenet.fr (Eric Tholome) Subject: Re: Which Countries Have Competition (for FAQ Update)?

Indeed, competition will be introduced no later than 1998 in most European countries (except in countries that specifically asked for a delay). Actually, we need to be more precise: for instance, we tend to think that the French public telecoms are still under a monopoly, which is almost true, except for international and mobile communications, which have long been open to competition (and there has indeed been competition for quite some time). I don't recall what exactly will be opened to competition in 1998. I believe the story says that all services will, but not infrastructures, though many countries are willing to open *everything* to competition by 1998. Can someone be more precise on this point? Otherwise, I'll have to look up my archives. Hope this helps!

I may start a callback service of my own. Well, let me give you some figures: France Telecom's rate to call the U.S.A. varies between $0.95 and $1.27/minute depending on the time of the day. My ATT calling card isn't much cheaper, especially because of the $2.50 initial charge. My callback operator does not require a minimum monthly charge, nor does it impose a monthly fee. It charges $0.66/min at any time for the same call. You're right that I'm also charged $0.14 for my call to the callback center. Moreover, my callback call is timed from the moment I get the American dial tone (only if the call is answered), which adds another $O.15 (approximately). Still, if the call lasts a minute or more (which is almost always the case, even for calls that reach an answering machine), my callback service is a good deal; a very good deal. I called an American friend last month and we stayed 70 minutes on the phone. I saved around $25 thanks to my callback operator. Not bad, right? To be totally honest, I must add that my callback operator times the call in 30 second periods, whereas France Telecom uses circa 7.5 second periods. Who cares? The service is so much cheaper. I'm looking forward to signing up for your new callback service (still to come), which will have to beat mine! :-) Eric Tholome 23, avenue du Centre tholome@dialup.francenet.fr 78180 Montigny le Bretonneux phone: +33 1 30 48 06 47 France fax: same number, call first! ------------------------------ End of TELECOM Digest V15 #58 ***************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa19137; 24 Jan 95 22:59 EST Received: by delta.eecs.nwu.edu (4.1/SMI-4.0-proxy) id AA13570; Tue, 24 Jan 95 17:42:17 CST Return-Path: Received: by delta.eecs.nwu.edu (4.1/SMI-4.0-proxy) id AA13563; Tue, 24 Jan 95 17:42:15 CST Date: Tue, 24 Jan 95 17:42:15 CST From: telecom@delta.eecs.nwu.edu (TELECOM Digest (Patrick Townson)) Message-Id: <9501242342.AA13563@delta.eecs.nwu.edu> To: telecom Subject: TELECOM Digest V15 #60 TELECOM Digest Tue, 24 Jan 95 16:40:00 CST Volume 15 : Issue 60 Inside This Issue: Editor: Patrick A.

US West has offered Caller-ID in the Phoenix Metro Area for over a year now, and I have been quite pleased with it. All non-cellular local calls either have display a name and number, or PRIVATE NAME for blocked calls.

PAT] This is an interesting analogy, but it's not quite what the original poster was trying to say, I think. To expand: If said supermarket were to suffer from a crime wave, and a certain amount of milk were stolen, but no more milk than would normally be discarded in any given week as you described, what if the supermarket then turned around and announced it would increase its milk prices to make up for its losses? Should it figure the value of the lost milk at full retail, or at wholesale? It would not have sold the milk; if they recover the full retail price, they would end up making more money than they would have if the crime had not occurred in the first place. Persomally, I don't think that's reasonable, from the customer's point of view. When you move from supermarkets to cellular carriers, an additional factor comes in. The cellular system transmits its authentication in the clear, making it relatively easy for modern crooks to commit cellular fraud. I've seen lots of people here mention this, and it seems the carriers must have known this weakness. To go back to the analogy, would the supermarket customers be happy about rate increases if they found out the store had knowingly left the back door unlocked and unguarded every night, at the time the milk thefts occurred? I see the point as being: the cellular customers are not responsible for the theft of their billing codes. They exercise reasonable caution in protecting the company from fraud; it is the system that is at fault and it's not reasonable to ask people not to use their phones. In this case, it's bad enough to be charged for theft beyond your control, and even worse to be charged based on theoretical costs that will net the company more money than they'd get if there were no crime to start with. Rob Levandowski Computer Interest Floor associate / University of Rochester macwhiz@cif.rochester.edu [TELECOM Digest Editor's Note: I am reminded of several years ago when I had a neighbor by the name of Mike Polonski and his wife. They were an older, retired couple. Not being able to get by on what Social Security paid them as a married couple, they decided to get a divorce -- after fifty years of marriage! -- so that each of them would begin getting their own check each month, in a total amount higher than what they gpt as a married couple. None the less they continued to live together, they were simply divorced in the eyes of the law is all. We would get together for dinner at least once a week, sometimes more often. Time and again, at dinner in their home, we had only the finest meats, vegtables, and other foods. Where do you do your shopping, I asked ... Mr. Polonski's answer shocked me: the Carnegie Safeway dumpsters every Tuesday about midnight, he said. He saw my startled look and explained what I said in my previous message. Every Wednesday morning at 4:00 am the semi-trailer truck full of stock for the store would show up. About the same time the refrigerator truck would show up with milk, eggs, butter, ice cream, etc. Then soon the 'bread man' would be there. In anticipation, the stock clerks late Tuesday night began cleaning out the old stuff from the shelves; anything with an expiration date *even two or three days ahead* had to be disgarded. The store knew the stuff was still good, but they figured if someone had milk at home with the current day or the day before as the expiration and they got sick for some reason they would blame in on the 'spoiled milk' and sue the store. It was easier to dump it all. You would not believe all the stuff they throw out ... I know I did not believe it until about a week later Mr. Polonski came to my home and brought three large shopping bags with him. "Here," he said, "I did your shopping for this week." He had already taken home three or four bags for himself, and these were mine. Milk, peanut butter, crackers, bread, several boxes of macaroni and cheese, hamburger helper, two packages of pre-sliced balogna (this was in the winter; I caution you against taking the meat or dairy stuff in the summer!) and more. Everything had some minor thing wrong with it; usually it was near the 'must be sold by' date. Some boxes were smashed. A box of 48 Milky Way candy bars where two of the bars on the top row had been sliced in half accidentally with a box-cutting knife. I asked him if he ever had the nerve to take something he did not want back inside the store to the courtesy counter to get a refund and tell them he 'lost his reciept' ... he said no, but he knew of one older lady who 'did it all the time' until Safeway finally slapped her hands for it and told her to stay away from the store and the dumpsters.

There are a number of PC based solutions for being able to take multiple line analog and digital trunks, do stuff such as play voice scripts and capture DTMF Digits, generally referred to as VRU or to actually recognize the the caller's voice, generally referred to as Voice Recognition. Natural MicroSystems of Natick MA and Dialogic of Parsippany NJ are a couple of names that leap to mind, although there are certainly others.

Alot of the major manufacturers go about their upgrades in this way. Pretty well EVERY Voice Processing manufacturer uses regular off-the-shelf components, and they are all PC-Based (whether they like to admit it or not.) Some claim "stand-alone" but that just means they sell their components under their own name and proprietary nature, and charge crazy amounts of dollars for it. They often install a 200+ MB HDrive into their systems, but only format a certain percentage of it depending on how much you pay for. Then, when you upgrade, they send out a technical specialist who inserts a 5 1/4" floppy and runs a little UPGRADE program that basically formats a larger part of the drive (as they put it, "unlocks more memory". So, you end up paying hundreds of dollars for something that should really have no cost involved at all.

Any interface issues we should be aware of? I've had an OCTEL "Aspen" (mid-sized) system in service since 1990 (nearly five years now) with absolutely -ZERO- downtime. It is fully integrated with my Mitel SX2000SG pbx and just keeps working and working. I originally purchased a service contract from OCTEL but finally let it go as they were about like the Maytag man... :-)) I've had them out once, to replace a disk drive. My Octel Aspen system has 20 ports and serves approx. 800 users. Much to Octel's chegrin, I'm still at the original installed software rev level, 8.45.:-) My system is running four 80-meg drives and is still at less than 1/2 capacity. Small mailbox sizes and short save times help that alot. I typically allow each user a max of 20 two-minute msgs with a "new" message hold window of 21 days and a save/archive window of seven days, tho I do make an occasional exception -- just don't let it become a filing cabinet nor an attic. Make that a -POLICY- and your life as System Administrator will be much more pleasant. Run monthly subscriber usage reports to keep tabs on your big "exception" mailbox users as they can bring your disk space to its knees if they abuse the "save" priviledge. Force passwords to six digits, minimum. Beware that "auto attendant" can become a sneak path for toll fraud with any voicemail system. Otherwise, it takes a licking and keeps on ticking. Expensive? Yes. Worth it? You tell me ... As an aside, my Octel/Aspen system sits in a 68-degrees/temp-stable environment and is powered through a Liebert PDU (clean power), plus has a sturdy industrial grade UPS behind it. That may contribute to the good results thus far achieved. I know if the need arose that I'd sure buy another one in a heartbeat.

MHEC-TEL is intended as a forum for discourse and information exchange by telecommunications professionals within the higher education community and others interested in opportunities enabled by telecommunications tech- nologies -- for example, distance learning, teleconferencing, interinstitu- tional resource sharing and programming cooperation. List membership is not geographically constrained -- the list welcomes higher education administrators, faculty and professionals from all regions of the country. However, discussion on the MHEC-TEL list should avoid focus on issues of no applicability to institutions in the Midwest. To subscribe, simply follow the normal protocol for Bitnet list subscription. Send a message to: LISTSERV@UMINN1.BITNET (or LISTSERV@VM1.

The list-owner for MHEC-TEL is Jeff Williams . ---- opening message on list ---- Welcome to the Midwestern Higher Education Commission's Telecommunications listserv. The MHEC-TEL list has two main purposes. The first is to provide a forum for higher education telecommunications professionals to share ideas, questions, comments, and announcements with peers across the Midwest. The second is to solicit ideas and suggestions from telecommunications professionals in MHEC member states about common institutional challenges, existing MHEC programs, and future cost-savings initiatives. Each of you is welcome (and encouraged) to tell your higher education colleagues about the mhec-tel list and discuss its contents. However, MHEC wishes the list to remain "private" within the higher education community; commercial entities, such as equipment vendors, will not be allowed to join.

It will really be the 23rd, the lady says. Okay, I waited until Monday afternoon and tried it ... still nothing. I get intercepted at the 1-500 and 0-500 mark; Ameritech will listen to nothing further after that. I call back to AT&T and ask them about it. The lady put me on hold for the *longest* time -- about ten minutes -- then comes back and says Ameritech won't have it turned on until January 30. So on that day I shall try it again; who wants to bet me I will still get intercepted at the local switch? And of course, poor, put upon little AT&T: 'there is nothing we can do about it; the local telcos have to install the billing software ...' Well heck, in case she has not heard, Ameritech and AT&T have been fighting over the access fees to be charged for 500 service, and Ameritech is planning their own 500 service.

This was to be I-495, which: split off NJ Turnpike at what is now exit 16-E; was to cross Manhattan from Lincoln Tunnel to the above- mentioned Queens-Midtown Tunnel (this stretch was never built), and then emerged from there as the Long Island Expressway, becoming N.Y. 495 at or near the Clearview Expressway in eastern Queens. The latest I remember now is that the stretch in NJ is state route 495, and I-495 signs were erected from Queens-Midtown Tunnel all the way to the expressway's end in Suffolk County (eastern Long Island). Old maps had I-78 crossing the Manhattan Bridge, passing near the JFK airport, then turning north to the Throgs Neck Bridge (into the Bronx) and hitting I-95.

Date: 24 Jan 1995 12:02:45 GMT Organization: Express Access Online Communications, Greenbelt, MD USA The most basic difference is that a T3 is roughly 28 times "faster" than a T1. T1s are 1.544 Mbps while T3s are 44.736 Mbps. Telcos and big telecomm users often aggregate their T1 traffic onto T3s with an M13 type multiplexer or a 3:1 digital cross-connect machine. This is just a start. The line coding is different as well. T1s uses AMI or B8ZS, whereas T3 always uses B3ZS.

Obviously, you don't believe that Bell companies give anything away. I suppose you also don't believe in the tooth fairy . Seriously, there must be a tariff filed with the state utilities commission for them to collect money, on a regular basis, from multiple customers (IXCs). Check your local telco business office. In most states, they are required to make their tariffs available for public inspection. (Maybe we should start a movement to pressure PUCs to require that tariffs be on the Internet?) (Maybe they already are in some states?) Consider the case of the small telco (non-Bell), in Nebraska, I believe, that apparently had some mysterious financial relationship with a local filthy talk operator. Said sleaze bag (my opinion) advertized his "service" all over the country, and listed an ordinary area code and number, not a 900 SAC. The net income of the telco reportledly went up spectacularly in the ensuing months. The filth peddler continued to operate, and expand his system. Since he was merely receiving ordinary long distance calls, he had no obvious source of revenue to support his generosity. I read about it in the {San Diego Union Tribune}, because a local mother of a teenage girl was stuck for thousands of dollars of ordinary toll charges, even though she had arranged with the local Bell company to block 1+900 calls. Getting back to your question, it would appear that the various long distance carriers involved in carrying these calls paid the local telco for such termination. This used to be called something like "settlements and separations" before Judge Greene "fixed" the phone system. Hope this helps!

Much of our long distance is via a top-notch reseller in Atlanta. When there are billing or other adminstrative errors, overlaps, etc., one phone call to her, with a documenting fax, is all it's ever taken to straighten the problem out.

I agree that different SIMs are pain. But, it's really not that bad. All Swedish operators offer two-card subscriptions. Two IMSIs but one phone number. Only one phone can make or receive calls at the same time. I don't have a cellphone myself. But I've been told that on Europolitan you must dial 333 to "change IMSI" but on Comviq you only have to turn the other phone on. The IMSI last to do a manual update is the one that gets the calls. How it works on Telia I don't know.

NYNEX, Bell Atlantic and Ameritech probably have them, if they weren't sent back to Western Electric to be scrapped -- the service was offered in New York, Chicago and Pittsburgh, with other cities getting intercom-only Picturephone service (i.e. you could have it within your own PBX but not to other sites because the video switches weren't in place). The Bell System also had a setup for several years between top executives at 195 Broadway and the presidents of each of the BOCs, and some other BOCs obtained sets to be used for demonstrations.

Unless you and the other party shared a ring (ie, one long vs two short) you heard nothing -- you just had to wait a while and pick up the receiver and find out if they were there. Of course, this system could always be used to ring your own phone as well. When the Jehovah's Witnesses showed up, an accomplice would ring the phone, then annouce you had an important call.

AT&T was not the first to deliver long-awaited "Follow-Me" Numbers. A case in point: a company in Michigan called US Signal was in fact the first to have TRUE "Follow Me" capabilities. The AT&T card is really a FIND ME card where it calls a set of preprogramed numbers; this service can get expensive real fast. UniDial Communications [TELECOM Digest Editor's Note: And despite their statements that 500 numbers would be available by now, they still are not turned on, at least here in the Chicago area. I was one of the first people to sign up for 500 service when they started taking orders. Despite calling within a day or so of their announcement that orders were being accepted, there were absolutely *no* good numbers available ... already taken, I was told. Yeah, we know how AT&T does that; trying to get 800 numbers away from them and into the hands of another resporg or carrier got me soured. All these 'reservations' and never once a name to go with them. Well, be that as it may, they told me back in December that my 500 number would take a month to turn on but be available January 20. Comes last Friday, they said it would be Monday the 23rd ... now they are saying it will be next week on January 30. As usual, point your finger at someone else; the rep claimed to me that Ameritech does not yet have the billing software in place; that's nonsense because in fact I got billed for my first month of 500 service by AT&T back on January 24 as part of my Ameritech bill. Watch on January 30 for some new date to be set. Why wouldn't the AT&T reps have known this when they took my order now over a month ago?

I first encountered CO codes in this format at least ten years ago when I was calling a Southern California firm with which my company was doing business.

In 817 these prefixes are listed in the N(0/1)X format: 410 and 806 And in the 214 area code: Southwestern Bell exchanges: 508 703 712 812 704 707 815 202 204 212 215 305 314 502 504 601 602 603 606 609 616 707 801 802 803 804 805 807 808 906 908 909 912 913 914 708 709 217 218 515 617 302 309 302 312 819 407 713 401 402 506 406 919 308 404 419 701 702 715 716 301 705 801 802 803 907 917 918 902 904 706 503 613 203 319 819 905 216 GTE exchanges: 313 413 513 514 518 607 714 717 718 719 915 916 219 304 315 317 316 318 306 307 416 417 418 403 516 517 519 604 605 608 612 618 619 205 303 414 (These were scooped off the maps arranged geographically by wire centers/zones, so they are not in numerical order and I might have missed one or two.) This was two and a half years ago, and there are probably more of these now. I know the Houston metropolitan exchange (area code 713) also has a lot of CO codes in the N(0/1)X format.

For many years, what became the {News-Journal} newspapers were on what became 302-654-5351. (Please don't call that number; it was changed long ago!) Originally (and I had to read about this since I am too young to remember that far back) it would have been printed as "Wilmington 4-5351" or simply "4-5351" with Wilmington being understood; I believe you had to ask the operator if you wanted to reach such a number. "Wilmington" was replaced by "OLympia" (OL for short) when it came time for customers to be able to dial directly. Then, in 1966, Diamond State Telephone stopped printing exchange names in the Wilmington phone book, and existing numbers of form OLx-xxxx began to be printed as 65x-xxxx. TELECOM Digest Editor's Note: Until the late 1960's a peculiar thing existed in Lafayette/West Lafayette, Indiana with Purdue University and the rest of the phones in the town. Lafayette was surrounded by area code 317, and it had seven digit numbers like everyone else, yet it was not direct dialable. You could call Indianapolis, or towns on either side of it by dialing 317 and the number, but for Lafayette and West Lafayette you asked your operator for the number. Purdue had five digit extension numbers, and locally from within town if you knew the desired extension you could dial 92 plus the five digits. To get the Purdue operator from anywhere in town, you just dialed 90. If you were calling from somewhere like Chicago, you dialed 211 for the long distance operator and asked for 'Lafayette, Indiana nine-oh' or perhaps for nine-two-whatever. Finally about 1970 long after everywhere else in the area was dialable, Lafayette and Fort Wayne (both were served by GTE, both had seven digit numbers like everyone else) got connected with everyone else. Does anyone remember when all the military bases around the USA had their own special arrangements? Camp McCoy in Wisconsin, for example, was just 'Camp McCoy' to the long distance operator; it had four digit extensions but no actual 'main listed number'. It was just 'Camp McCoy, extension xxxx' via the long distance operator. Ditto Fort Benjamin Harrison in southern Indiana and Great Lakes Naval Base.

I am specifically interested in accounting details, i.e. what costs should be considered and how to calculate cost-of-service. I searched through the FCC gopher but did not find anything with this level of detail.

On one line we feed three transmitters since they are for buildings next to each other; the other line is for a building some 150 blocks from here. Should we stick with analog lines or slowly move over to other types of communication by phone? The fact that we have to branch off led me to believe that we should go for digital transmition, so that we would have less noise and a better signal. Does anybody have experience with this? We are located in Manhattan and NYNEX is not of much help. Getting our current two lines to work properly without too much loos was already a great victory for us. Our budget is limited as we are a college radio station. All help is greatly appreciated.

On 1/15/95, the 205 area code (Alabama) was split into 205 and 334. 205 remains the area code for LATAs 476 (Birmingham) and 477 (Huntsville). LATAs 478 (Montgtomery) and 480 (Mobile) were moved to the new 334 area code. The following is a list of the NNXs that have moved to the 334 area code. This list does NOT come from any official source, but my sampling of it seems to agree with the ad posted by South Central Bell in the 1/16/95 Communications Week. There is a "grace" period for which both the 205 and 334 area codes will work, but I left the Comm Week at the office, so I don't have the exact date. I seem to recall the "grace" period ending in June or July though. For more precise information for programming PBXs and such, call SCB (they had an 800 number in the Comm Week ad). At the end of the "grace" period, I assume that SCB (or is it Bellcore) will start assigning new NNXs that may duplicate in the 205 and 334 NPAs. Again, this following information is NOT guaranteed as it is extracted from a personal database. My use of the database requires that I keep it as accurate as possible however. For exact details, you should consult the Comm Week Ad and/or call SCB.

We receive our ISDN from a #5ESS. It was obvious, despite what is written about Bell Atlantic in "Reengineering the Corporation," that it is very inexperienced and unorganized in providing ISDN service. All we asked for was two ISDN BRI lines with NT-1s. It took about two months before we were able to get the lines installed, and we have already had to replace the NT-1s once. Anyone else have experience with Bell Atlantic ISDN?

Marinelli jmarinel@freenet.niagara.com [TELECOM Digest Editor's Note: Yes, this generally can be done. It is not real easy, and requires a degree of sophistication by someone who knows how to do it. It involves getting into the telephone network using a 'backdoor', using a dialup and passcode. In other words, what I am saying is certain switches have a phone number you can dial into, give the correct passcode, and then manipulate or make changes to the way calls are processed as though you were in the central office itself at a terminal and keyboard. Quite a few telcos have disabled this 'feature' for obvious reasons. I guess some still have it available. I would not have the slightest idea *what* commands/passcode to use, nor the numbers to dial to get into the switch. The commands probably stay the same from one switch to the next more or less, but certainly the phone numbers and passcodes are different. Plus, I strongly suspect anyone fooling around like this leaves tracks all over the place leading back to them.

Calls to the States from here cost you the (rounded) equivalent of 15 cents for every seven seconds of your phone call. That means billing is in those seven second increments as well; so if you make a phone call of, say, ten seconds you pay 30 cents and give the PTT a gift of four unused seconds. Hence, assuming it is possible to type six buttons on your phone within seven seconds (to enter your PIN), your initial call to the callback company costs you 15 cents. Now for the rates: I have seen Callback services that charge as much as 75 cents a minute; but the chepeast I came across so far was 51 cents per minute with a 30 second minimum and billing in six second increments. And that is without a monthly flat fee, or call surcharge. (Note: This is only for calls _from_ Germany _to_ the US of A.) So, a three minute call the direct way (ie. with "wonderful" German Telekom) costs you about $3.75. (This is all rounded). Using the Callback service it is $1.53 plus the 15 cents I used to call the Callback service, ie. $1.68. That's more than 50% cheaper! Things from France may look a little narrower, because German Telekom, as far as I know, charges the most in Europe, perhaps even in the world (which wouldn't surprise me.) But still -- you can apparently save from France too. > Part of the gimmick that makes callback services so inexpensive is > that you usually do not have to pay for a call to the USA.

I could not figure out how. PAT] Well, what's the difference (in terms of security) between calling a number, letting it ring a couple of times and calling a number and _letting_ them answer to punch in your PIN? I don't see any. The point you originally tried to make I didn't understand either: misdialed calls. If someone has your Callback number, he stole it or got it in some other illegal way. People can steal Credit Cards or Credit Card numbers too and cause quite some harm to you, although a harm more of the subtle kind -- it doesn't wake you up at three o'clock in the morning. Instead, it lets you sleep and comes in the (later) morning in your credit card bill. Georg [TELECOM Digest Editor's Note: Yes, AT&T was claiming that deliberatly causing a phone to ring then disconnecting amounted to sending coded transmissions without paying for them (which it does). When it was noted that AT&T's own answering machines use 'toll-saver' techniques the same way (if ringing phone does not answer within two rings, disconnect since there are no messages waiting for you), then the company found it difficult to object to others using their network in the same way. The difference between merely calling a number, letting it ring a couple times and hanging up versus dialing a number, waiting for an answer and specifically entering a PIN number is that the former happens how many ever millions of times daily when clumsy people dial wrong numbers and realize it within seconds of finishing the dialing. They then hang up, but the callback switch has no way of knowing if the real user was giving a signal or if some careless person caused that to happen. At least by inserting a PIN, a positive, specific effort has to be made. Most wrong number callers and telemarketing people don't get that far along.

I know I'm paying something like $3.50 a month to be connected to the LD carriers. At one time, it was something like $2, and was upped to $3.50. Maybe the difference at one time was paid by the LD carriers but it was later shifted to the subscribers. I think it had something to do with the old AT&T Long Lines high profits funding the local exchanges (before breakup). I know that my next bill will have another couple bucks added to the basic service charges to make up for the money lost from letting the LD carriers compete for intraLATA toll calls. That's going to make a lot of old ladies unhappy. I'm not pleased about it either, but I can afford it. Our district, with $30K bill, will be getting a four percent raise. That's about $1200 a month. I guess I should be happy. But the Pac Bell reps say that it will be a wash when the toll rates are factored in. Hmmm. > Anyone have any information on this topic?

In California, Pacific Bell charges $0.0142 per minute of "terminating access" to all IEC's, this rate is regulated at the FCC and I suspect Bell Atlantic has a similar tariff on file at the FCC.

In the olden days (before 1984's FCC-mandated rules change, which coincidentally was the same time as the Bell breaksup), there were "separations and settlements" in which the overall toll revenues were divided based upon a complex formula. Nowadays, the local companies use certain formulas to justify the rates they charge for "access" by LD carriers. When an inter-LATA call is carried from and/or to a local carrier, the inter-LATA carrier pays a tariffed rate. The last time I looked, the lowest rates were just over 3c/minute for either the originating or terminating end (thus over 6c/minute for both ends), but up to around 5c/minute for some telcos. There may also be a distance charge for intra-LATA calling TO the carrier's POP; typically this is 1/100 of a cent per minute per mile. That's their real "toll" cost base! In a few obscure cases (very small telcos) the price can be much higher, so the interexchange carrier is guaranteed to lose money on it. (America's Network columnist Art Brothers owns one such telco, Beehive Tel in Utah, which has extremely high costs and thus can charge something like 90c/minute to terminate calls there.) If a customer has direct access to an interexchange carrier switch (say, a T1 into the POP), thus not using (let's not use the "b word", bypass, here) the local Bell's switched network, the fee is avoided. Most big 800 numbers work that way, so only the consumer (caller) end invokes a Bell charge. The flip side is that for intra-LATA toll calls, a customer who hooks up as a carrier gets a lower price (3-5c/minute) than almost anybody's intra-LATA WATS rate. This is not impossible for a large user (there's a game called "rusty switch" in case you need to leave the LATA) so intra-LATA tolls are being forced down. NYNEX, at least, understands this and charges only around 5c/minutes for bulk business toll, and actually encourages big users to go directly to their own toll switches and hook up as carriers do for around 3c/minute. ------------------------------ From: edg@ocn.com (Ed Goldgehn) Subject: Re: LD Termination Fees to RBOCs Date: 24 Jan 1995 16:10:23 GMT Organization: The INTERNET Connection, LLC All fees charges for LD termination can normally be found in the Feature Group tariffs. Normally, LD carriers fall under (last I heard) Feature Group 'D' tariffs due to their method of termination. You can request a copy of these tariffs from each of the RBOC's or from the PUC in any State. BTW, the method of charges is entirely different for LD service in the cellular industry. With cellular, it is not unusual for local cellular carriers (RBOC's or otherwise) to provide FREE or flat rate termination charges to LD carriers.

This is known as "access charges" and is a basic feature of the phone charges. WHY DO YOU THINK THE LD CARRIERS ARE SO INTERESTED IN WIRELESS? It bypasses the local access charges and they keep the whole banana. This is a major threat to Local that is struggling anyway. This is the most likely reason RBOC's will get relief against the prohibition on doing long distance. Because: 1. Technically LD carriers will be providing local service which is prohibited too. 2. Local Service providers will have to jack up rates to survive and that angers users who for the most part don't make long distance calls (95% of all traffic is local, 40% of LD is to 800 numbers.) 3. The local rates have already been jacked up because those companies have lost the off setting revenue they use to get from LD before divestature, so angry localities are demanding competition for local service just like there is competition for LD. To do that would drive prices down even further and really kill the RBOC's. 4. Local's revenue stream is from access charges. To their benefit though, they do get the fee even if the call isn't completed. RBOC's will have to be allowed to do long distance, provide information services, provide video delivery and anything else they can to off set lost access charges.

Telecommunications providers generally engineer their network so that the bandwidth should never be saturated; it's common to target something like 40-60% load. So if fraudulent calls increase the load on the network, the carrier will have to increase the capacity to accomodate it. This costs money, but because the calls are fraudulent there's no corresponding income to pay for it. This is precisely the same as any other kind of theft: the vendor fails to receive income when someone gets something that the vendor paid for.

Date: 24 Jan 1995 13:37:18 GMT Organization: Delft University of Technology, Dept. of Electrical Engineering The preceding discussion compared cellular fraud with making illegal copies of software or tapping the signals from the cable television company. I believe that those cannot be compared because cellular phone facilities and the cable television signals can easily be pro- tected from fraud or theft without hampering the legitimate users, unlike software, where copy-protection invariably reduces the use- fullness and attractiveness of the product. A cellular phone or cable television facility is a product that has value. Protection from fraud is technically feasible and affordable and does not reduce the usefullness of the system. (In fact increased protection from fraud _increases_ the attractiveness by reducing the probability that customers are billed for calls that they did not make.) The fact that the providers of cellular phone systems do not protect their product suggests that said providers make more profit from the product in its current state than they would if the product was adequately protected. The legitimate users pay part of the cost of the fraud. More is paid by the taxpayers through the provision of police and justice systems that track down and prosecute phreakers. Using taxpayer's money to track down and prosecute phreakers should stop until the providers of cellular phone systems add _reasonable_ protection from fraud to their product. Customers of those cellular phone companies (should) know that each bill must be scrutinized and anticipate to dispute billing errors. If they do not want the hassle, customers should select a provider that has a better product. Cable companies can protect their product from unauthorised use (i.e. theft) at a reasonable price without hampering legitimate users. Regretfully, software producers do not have this luxury, therefore it is acceptable that software producers rely (in part) on the police and justice systems to control illegal copying. Generally, everyone is obliged to make a reasonable effort to protect his or her products and properties from theft, vandalism or misuse. The police and justice systems are public services for cases where reasonable protection fails, or is impossible.

To take an example, a friend of mine brought an AP story to my attention today about an "attack" on the internet that makes it possible for people to "steal information" and makes it sound like it is a really great crisis that is a fantastic threat to the "information superhighway", that people are going to tap future commerical traffic on the internet to steal credit card numbers and so forth. Now it's certainly true that people are doing things like this, but our beef with the article is that this has been going on as long as there has been an internet, as long as we've had data networks, and that it's something that we're going to live with as long as we have data networks. The media plays up particular incidents as if they were world shattering, as if they were warning us that there is a band of cocaine-crazed Lybian terrorists hiding an atomic bomb in somebody's basement, instead of recognizing individual network 'incidents', computer viruses and so forth as rather common events: not any more newsworthy in themselves then would be individual muggings in central park. What the media ought to be doing is to put electronic intrusion, vandalism and crime into context, how this is a problem inherent in our social organization and technology and that it's something that we have to find ways to live with, instead of something that we should be cowering in fear about. Similarly, every few months, some paper somewhere prints a story about the discovery of a "vast pornographic computer network" with 8 million users, thousands of sites and so forth. That's right, somebody just stumbled onto the alt.sex hierarchy or a secret cache of porno GIF's, so now your local paper prints that the local research university has not only been corrupted by post-modernist deconstructionalist Marxist English professors, but adding insult to injury, is part of an international porn conspiracy called USENET. There's no mention, of course, that you can also read comp.dcom.telecom, rec.arts.startrek.tech, sci.chemistry, comp.os. linux.announce, or even alt.angst! [Except of course, when an AT&T PR man told the media that people from the "network" (meaning comp.dcom.telecom) who were communicating and complaining about the USA Today 800/900 incident were people who were interested in "getting something for nothing". (Remember that Pat?)] More recently, we can consider media coverage of the Canter & Siegel affair, heroes of the {Wall Street Journal} editorial page right up there with Milton Freedman, Arthur Laffer and Margaret Thatcher. It hurts the electronic community when software publishers wildly overestimate their "losses" due to software piracy. It leads to alarmism, crippled shareware, and looses dongle-peddling charlatans on the street. [Why don't dongle ads show the twenty-odd dongles that you'd have hanging off your parallel port if every software publisher used dongles? A fellow worker had what amounted to a cute little CNC milling machine that cut traces out of circuit boards; it was controlled by a propreitary piece of software that ran on an IBM PC -- and even though the software was only useful to control a piece of hardware manufactured by one company, it was still "protected" with a dongle!] Digital storage and communications create a crisis in intellectual property, this is a technological fact. Our society needs to find some way to protect the rights of people that produce information products and those that use them -- and when industry screams like chicken little about hypothetical losses, it doesn't help us think clearly about the problem. It is the same thing with the cellular phone companies; the problem of cellular phone fraud is real; but if they want the public [including the police, regulators, etc] to be part of the solution, they'd best come clean about the economics of cellular phones. ObAnswer: To directly address Paul Robinson's question, I had the impression that an awful lot of cellular phone phraud is directed out-of-the-country, particularly to third-world countries that have absurdly high phone rates. According to a phriend, a cloned phone is typically going to cost an "end user" something in the $100-$300 range, though people sometimes program phones for less (like $50 or so); you have to talk a ~long~ time to justify that cost making local and long distance calls in the US. Compare this to a typical cost of $8 or so for a code. Unless Colombian Dial-a-Druglord and Bangladesh Telegraph and Telephone are remarkably forgiving, I think cellular phone carriers ~are~ paying for those calls. ------------------------------ From: jdearing@netaxs.com (John Dearing) Subject: Re: T1 vs. T3: What's the Difference?

Most of the service lost is in Minnesota even though the cuts were in North Dakota. Some cables were above ground, others were in manholes. Most were cut in several places so simple splicing is not possible. Some of the cables were up to five inches in diameter. Full service has been restored as of Tuesday night to the Fargo area, with only 911 service and long distance service restored to Moorhead, full service is expected to be restored by Saturday. Emergency services had cellular service available and instructed people needing assistance to go to the local fire stations or police stations to seek help. I have not heard of any emergencies that were worsened due to this, but many areas in northwestern MN had no dial tone for several days. I believe as many as 500,000 people were impacted by this at one time or another. The police and FBI are looking for a suspect in a burglary of a stereo store from Saturday night where the alarm wires where also cut. Initial suspicions were that it was someone with knowledge of the system due to the way things were damaged, however the current burglary suspect is not a past telco employee according to current reports.

Does anyone know if the major LD carriers, notably AT&T, Sprint, & MCI, foward CID information interstate? As secondary questions, (1) can anyone tell me if the areas of Louisville, KY and Cincinatti, OH can send the CID information and (2) whether Pennsylvania (that CID-fearful state) will accept the information? The Bell Atlantic person told me that PA switches suppress CID information on INTER-LATA calls, but my understanding is that this is only an outgoing suppression, not an incoming supression. Specifically, I'm interested in pinning down why I get an out-of-area message on calls from Louisville, KY to my number in Pgh, PA. They use MCI, I use AT&T.

Philco was a big U.S.A. appliance company not connected, at least at that time, with the Netherlands electronic giant N.V. Philips (not Phillips). "Philco" was formed from the company's original corporate name, the Philadelphia Storage Battery Company, and was one of the biggest manufacturers of radios in the 1930s and probably earlier. Perhaps they got into radios as allied to their battery business, since radios, at least home radio receiver, originally were all battery operated. It is my recollection that they became a major player in the television business because in the 1930s they acquired the rights to the patents of Philo T. Farnsworth, who had invented a television system entirely compatible with, but not the same as, the system invented by Vladimir Zworkin, the RCA genius. Farnsworth invented his system at age 16 and was granted the key patent at age 22. Some commentators have suggested he has largely been dropped out of the history of television because the idea that this callow youth could have developed a system that worked as well as the system developed by great corporate laboratories staffed with multiple Ph.D.'s is inconsistent with the supposed value of extensive higher education and big R&D expenditures, and the big embarrassment this caused RCA. Philco, I believe, was the only manufacturer that didn't have to pay licensing fees to RCA, although I think they later reached a cross-licensing agreement with RCA. Philips, the Netherlands company, was not very well known in the United States before World War II. During World War II, after the Netherlands was occupied by Germany, their American operation became separate under the name North American Philips Company, which used the trade name Norelco. But Pat's description of the early television sets and how they developed is right on the mark. > Five digit numbers were common in communities which had automatic > dialing systems in those days but only one exchange in the > community. Since the exchange name was always the same, it was > assumed when dialing. In your example you parsed the number > incorrectly. It was 8-2247, or to be complete about it, > ROckford-8-2247. I couldn't speak to the situation in Rockford, but I'm very familiar with Oklahoma City, which had five-digit numbers for many years, starting in 1920 when the "Northwest" office was put into service as the first dial operation in the city (and the first central office outside the downtown area). The downtown office was all manual, with exchanges Maple and Walnut (not MAple and WAlnut; they were manual exchanges and you spoke their names to the operator). The manual numbers were the exchange name plus one, two, three or four digits: Maple 5, or Walnut 4434. Maple 5, for example, was not Maple 0005; it wouldn't have had any meaning in a manual exchange. The "Northwest" office (it's really part of the inner city now) had five-digit numbers starting with 4, such as 4-1468. But there was no name associated with that; there was no toll dialing and it was just 4-1468 in Oklahoma City; not Oklahoma City 4-1468. The downtown office was cut over to dial in 1928, using the prefixes 2 and 3. Tulsa had a different history, and right up until the days of 2L-5N numbering (seven digits expressed as two letters and five numerals) in the 1950s or 1960s, had four, five and six digits numbers. In a small town I lived in (Konawa, Oklahoma, one of the first CDOs in Oklahoma) the numbers were three and four digit. My home number was 287; office 234. Four digit numbers there were party lines; the central office was terminal per line and the fourth digit selected the type of ringing. It's true that Bell companies usually recommended printing five digit numbers as "8-2247," as Pat said, and six digit numbers as "54-1468." But it was variable; Dallas and Houston expressed their numbers as, for example, Riverside-4085, which was dialed as R-4085. But not too many telephones outside the largest metropolitan areas had letters on the dial in those days. And independent companies often recommended displaying numbers in different ways, such as 8-22-47, or 82-247. "All Number Calling" (ANC) (seven numerals) came after the 2L-5N (two letter and five number) arrangement, usually in the 1960s or thereabouts.

Plain and simple ... ethically, there is NO difference between cellular fraud and calling card fraud. Both of them require the carrier to purchase additional equipment or potentially deny service to a paying customer. The carrier can't always eat the costs.

Until very recently, all local numbers were dialed as just five digits. Until about ten years ago, all local numbers were 5-3xxx, but they are now up to 5-2xxx and even 5-8xxx numbers. However, as of a few months ago, you now must actually dial the entire seven-digit number for local calls! (All long-distance calls are eleven digits.) They finally got touch-tone some time in the late 1980's. The reason for the change, however, is that the local calling area is being expanded slightly, to cover points as far as 30 miles away. It will now be a local call to phone Fannin, Charco, Weesatche (all 30 or so subscribers), and Victoria (a town of 50,000 or more with an airport and two TV stations).

With regards to International Freephone service, it would seem that a country code *other* than +800 should be used, due to the possible confusion this would create with the domestic toll-free services, most of which use an "800" code already. One potential problem is that someone intending to call a domestic 800 number might try to use the international format instead -- a company called as a wrong number might have to pay the international charges.

I believe the Los Angeles area was mentioned in this respect, and if there are holes in the listings because of different telephone companies that is a retrogression. At one time there were 30 or 40 telephone companies in the L.A. area, and they somehow reached agreement (possibly at the prodding of the P.U.C. or local civic leaders) to issue regional books with the listings "interleaved" (all in one alphabetical list). For example, one for Northwestern, one for Central, etc. The independent exchanges were dotted all over the area. There was no indication in the listings as to what telephone company served what customer. The yellow pages were a different story and each company usually issued yellow pages, and sold yellow page advertising, only for their territory. So a book would have complete white pages listings for the area covered, but only yellow pages for the area served by that telephone company. Now, of course, the independent companies have all been absorbed by GTE and the only two players are Pacific Telephone and GTE. But I'd be surprised in the P.U.C. or public pressure would let them go back to issuing directories with "holes" in the area covered. Yellow Pages directories, "locality" directories and private directories, of course, are an entirely different story. Wes Leatherock wes.leatherock@oubbs.telecom.uoknor.edu wes.leatherock@f2001.n147.z1.fidonet.org [TELECOM Digest Editor's Note: Sometimes all the listings will be in one book but in separate parts. For example, I remember seeing a couple of books issued by Bell a few years ago which covered some regional area, however after that part of the book finished, and some other pages were put in the middle (maps, etc) then another set of white pages started, with a notation saying something like 'alphabetical listings for Podunk'. 'Copyright 19xx, Podunk Telephone Company'. So they were in the directory of record for the area (the Bell System directory) but not actually merged with it. Other times, such as with Illinois Bell and Centel, the Centel listings for Chicago only are part of the Illinois Bell Chicago White Pages, with no reference at all to the fact that they are part of a different telco.

This sounds like the typical "carrier current" scenario. We had the same sort of setup when I was in college. Since the 8 kHz line well exceeds the bandwidth you can cram thru an AM radio, the two remaining questions are noise and cost. For your "close" string feeding the four buildings -- is there enough noise on the line to be objectionable? How about the 150 block run? Your "yu" login tells me you're in NYC, which means twenty blocks to the mile. Thats about seven miles then, give or take the zigzagging to and from the telco COs. Presuming that the noise and bandwidth are acceptable on both lines, look at cost. What will NYNEX hit you with for a digital line? One more thought, especially if you want to save money. Does the school have some sort of dedicated carrier already connecting the locations? A T-1 maybe? And can the Telecomm or MIS dept or whomever runs it, spare you a bit of bandwidth? [TELECOM Digest Editor's Note: New York City has twenty blocks to the mile? Gee whiz ... they must be very small blocks. In Chicago we have eight blocks to the mile with the exception of one area just south of downtown where there exist twelve blocks to the mile, and that's only for about one mile.

Thanks! Evan [TELECOM Digest Editor's Note: Actually, it is eleven digit dialing, not ten digit if you count the '1' on the front. However, one would think that when this becomes universal all over the USA that we could in fact get by with ten digits since the '1' would no longer be needed; there would be no 'local' calls to distinquish from 'long distance'. Since everything that we dial would consist of area code plus seven digits, there would be no need for a '1' to indicate that 'what follows is an area code' -- everything that follows would be area codes! It would be nice to see the '1' vanish under those cirucmstances. Or maybe they will insist on keeping it using as their rationale that '1' is also -- by coincidence -- the country code for the USA and Canada, and that what we are really dialing is country code, area code and seven digit number. As to *why* they are imposing it on calls within the same area -- as is supposed to be the case in Chicago beginning sometime in 1996 -- I do not know. Various reasons have been given.

Date: Tue, 31 Jan 1995 01:43:14 GMT A story in the Monday {New York Times} describes a Philadelphia area plumber who subscribed to Call Forwarding Ultra. This is a service offered by Bell Atlantic which allows subscribers to control call-forwarding from a telephone other than the one being forwarded. This plumber allegedly subscribed to the service for several of his competitors without their permission, and then forwarded their calls to his telephone. He then intercepted some or all of their business. He was found out after approximately one month, when one of his victims was complimented by a customer for a job well-done -- a job the victim never did! The perpetrator is currently in jail pending trial for an un-related charge of battery, but is now being charged with numerous counts of wire fraud, theft of business, operating a business under a false identity, and similar charges. Dave Levenson Internet: dave@westmark.com Westmark, Inc. UUCP: uunet!westmark!dave Stirling, NJ, USA Voice: 908 647 0900 Fax: 908 647 6857 [TELECOM Digest Editor's Note: This same report appeared in alt.dcom.telecom today submitted to that newsgroup by Jack Decker who concluded by saying this was a good reason telcos should password accounts, presumably to prevent fraudulent Call Forwarding among other things. The thing he neglected to mention -- nor was it mentioned by Dave Levenson here -- was that Call Forwarding Ultra (or Enhanced Call Forwarding or Remote Call Forwarding as it is known in other telcos) *does* require a password. If you have Call Forwarding on your line otherwise -- you have to already have it installed -- then if you further subscribe to 'Ultra' you are given a personal password or PIN. You dial a seven digit number which is the switch itself, begin by identifying yourself with your PIN, then give the number you wish to have (un)forwarded, followed by the number (if turning it on). The change takes effect immediatly. Needless to say, the switch keeps its own records on who called it from what remote location, with none of this 'private entry' stuff permitted. Typically, that number at the switch will not even answer or respond if the switch cannot tell what number is being used to call it before it answers. Also, no other custom calling features can be changed in any way, nor can any of the many other features of the switch be programmed using that PIN. So telco does make reasonable precautions to insure that one person cannot just call up and change the forwarding for someone else. What goes around comes around: Does anyone remember the old anecdote about the original development of automatic switching involving Alvin Stroger? Mr. Stroger was an undertaker a hundred years ago; he believed that the operators on the manual exchange serving his community had been bribed to divert calls from the public seeking funeral/burial services to his compe- tition. So the story goes, he developed the switch which came to bear his name as a way to be certain that manual operators at telephone exchanges could not wilfully give away his business to his competitors.

The World Wide Web is the term which refers to the interconnected set of documents which use HTTP. (World Wide Web is often abbreviated to WWW, W3, or just Web, although this latter causes confusion with a social issues information network by the same name.) Mosaic is an HTTP or W3 client program, often referred to as a "browser". In addition, the Mosaic browser has a graphical interface, and can utilize "viewer" software to display graphics, sound, and video in conjunction with HTTP "pages". There are other browsers, some, like WWW and lynx, text-based. Other graphical clients include Netscape, now being built by one of the original Mosaic developers, and a proprietary part of the new "Warp" version of OS/2. Mosaic, itself, exists in multiple freeware, shareware, and commercial versions, and can be obtained for MS-Windows, the Macintosh, and X. For those who have access to the Internet, but do not yet have Mosaic or the necessary SLIP or PPP access, this book is an excellent guide to getting set up. Chapters three and four give quite detailed instructions for obtaining, installing, and configuring the program. This includes an explanation of the MOSAIC.INI file for Windows. Other resources include Mosaic and W3-related newsgroups and mailing lists. Chapter six is also a solid guide to the use of Mosaic to access ftp, telnet, Gopher, and Usenet news resources. Gilster's "The Internet Navigator" (cf. BKINTNAV.RVW) and "Finding It On the Internet" (cf. BKFNDINT.RVW) are both excellent works, and the weaknesses of this one are shortcomings only in light of that comparison. The explanations of the World Wide Web, HTTP, and Mosaic, while good, are not up to the previous standard. The directions are not quite as lucid, and sometimes seem to assume more knowledge on the part of the reader. Coverage of the actual operation of Mosaic could be stronger: figures would have benefitted from the use of pointers to items being selected, and the discussion of Mosaic menu items is better in the O'Reilly & Associates' Mosaic handbooks (cf. BKMOSAHX.RVW). Also, while Gilster does discuss the fact that the capabilities of HTTP, W3, and Mosaic may be misused for trivialities, that point is not made strongly enough. He mentions the frustration involved with trying to use Mosaic with a slow modem, but not the growing impact of massive graphic, video, and sound file transfers on the bandwidth of the net as a whole. copyright Robert M.

The agreement was signed in Santiago, Chile, today by Trade Minister Roy MacLaren during the trade mission led by Prime Minister Jean Chretien. The agreement provides the Chilean Ministry of Transportation and Communications with access to CRC's expertise in communications R&D including spectrum management, remote telecommunications, networks and broadcast technologies. "This agreement underlines the CRC's international reputation for excellence in communications research," said Mr. Manley. "The Centre's increasing participation in such international collaborations helps bring Canadian technology and capabilities to world, and translates into new opportunities for the growth of the telecommunications sector in the National Capital Region and Canada." Under the agreement, CRC will provide technical consulting services on a cost-recovery basis, technology transfer, exchange programs and set up conferences and technical symposia. There is no monetary value attached to the agreement. Any CRC technologies transferred will be subject to separate licensing agreements.

When someone calls my 914-643 number, and my phone rings in Brianhead, and goes unanswered, NOTHING happens! The ringing just stops, and the line remains open, but callers do NOT get any message at all! This is a particular problem as coverage is quite transient, and you can easily find yourself in a dead spot where there is no coverage at all. If you had been registered in the system 20 minutes prior to hitting the dead spot, calls will be sent out to Utah, yet since you are in a dead spot, the switch will not send any ringing tones back to the caller, and all the caller hears is dead air, ad infinitum! If the phone is inactive for more than 20 minutes, it usually resets to the NY switch properly, but the fact that no recording is reported when the phone is registered in Utah and either "off" or in a dead or "no service" area is particularly confusing to callers who already have enough difficulty waiting for the beeps, tones, clicks, and other messages which they frequently must endure to reach my phone while roaming. (Although NACN roaming is by far more seamless than most B-side systems ... the B side in the Northeast laughable in most cases with inane messages and hold times.)

Anyone else have experience with Bell Atlantic ISDN? There's another issue I neglected to mention in the original submission: billing. As I mentioned, the ISDN lines are used for experimental purposes, for maybe five to seven hours per month. Our usage bills for the latest three billing cycles are as follows (at $.05 per minute): November 94: 3228 minutes (about 54 hours) December 94: 3392 minutes (about 56 hours) January 95: 3406 minutes (about 57 hours). All time is charged for circuit switch data calls (BA's name). In no case did we actually use that much access. We have been trying to get call detail from Bell Atlantic for the specific charges (mostly dialed destination and time of day) to see if we can pinpoint the trouble. BA says it cannot provide that type of info, so that right now we're at a standoff. (I have trouble believing it can't do this.) If anyone has any experience with how ISDN is billed and if similar problems have been experienced, please let me know. We know we didn't use nearly this much time.

But it doesn't answer the question -- why are the carriers refusing to support the U.S. users that did make their wishes known? If it is such a participatory process, why are the U.S. carriers ignoring the users who are participating?

First do you know about the Motorola 326X FAST V.34? It has SDC at 28.8 with 85Kb sync thruput, and up to 128 async thruput. Motorola also has a 56Kp DSU/CSU with SDC that has 256Kp thruput on a DDS circuits It also has two TDM ports for ASYNC or SYNC traffic up to 19.2 that allow you to piggy back async on top of your SNA traffic. They sell for less than $1500ea. Most compression is done via software in routers. Most like Cisco partnership with a compression company such as Magnalink. When adding a compression stand alone device to a network ie they fit between the router and the DSU, and are no problem. For more information on compression products contact our FTP site at . Please feel free to examine other leading edge technologies listed in this FTP list. If you have any questions please call me at 1-800-837-4180. Regards, Jim Williams CODEX 3500 SERIES 3512-SDC BANDWIDTH EXPANDER DSU ------------------------------- Overview: Data Communications managers are increasingly faced with requirements for higher data transmission speeds, shorter response time and lower telecommunication budgets as networks migrate from traditional terminal-to-host legacy applications to those supporting LAN internetworking. The Motorola Codex 3512 SDC Bandwidth Expander DSU is ideally suited to this changing environment. The 3512 SDC Bandwidth Expander provides Synchronous Data Compression (SDC) on HDLC/SDLC framed data in one port while two additional ports support the lower bandwidth requirements of polled, legacy data and/or restoral requirements. The 3512 Bandwidth Expander is an intelligent, high-speed digital access device providing up to four times the available bandwidth using existing low cost DDS-I or DDS-II secondary channel type leased-line facilities. The 3512 SDC Bandwidth Expander DSU opens new dimensions in network design, flexibility, productivity and cost reduction by providing benefits such as: * Compression up to 4:1. * Reduction of bandwidth requirements without reducing performance. * Extends the useful life of existing telco facilities and equipment. * Reduction in file transfers and quicker response time. * Flexibility for future applications and network migration. The 3512 Bandwidth Expander DSU is available in standalone and rackmount configuration and offers all the features, performance, functionality and reliability of the 3512 family of digital leased-line DSU/CSU's. Product Highlights: * Transmits Synchronous HDLC/SDLC framed data at rates up to 256 Kbps over 56 Kbps point-to-point digital leased-lines providing cost-effective, superior performance LAN-to-LAN internet- working. * Three Ports Standard. One compression port for transmission speed reaching up to 256 Kbps (Port 3). The two remaining uncompressed ports, each supporting speeds up to 56 Kbps. * Port Two of the 3512 SDC Bandwidth Expander supports operation as an intelligent A/B switch for restoral of failed WAN links at rates up to 72 Kbps over analog dial circuits, and up to 256 Kbps over switched digital services (e.g. Switched 56). * Flexibility in network design with support for Point-to-Point and Multipoint Time Division Multiplexing (TDM), port sharing (MSU) and mixed TDM/MSU. High bit rate efficiency provides up to 55.2 Kbps available bandwidth in TDM modes with 56 Kbps service. Mixed compression and TDM is supported. * Integral asynchronous to synchronous conversion of non- compressed data is supported up to 19.2 Kbps. Limited distance modem operation is supported for point-to-point private wire circuits in DDS-I and DDS-II SC modes. Benefits: 1. The 3512 SDC Bandwidth Expander provides rapid pay back by providing the bandwidth of more expensive fractional T-1 services over conventional digital services to 56Kbps. 2. The 3512 SDC lets you build networks that support existing applications today with a migration path for future applications to be efficiently absorbed into an existing corporate network. 3. As a three port digital access device, the 3512 SDC Bandwidth Expander is a modular and flexible low-end data mux supporting mixed legacy terminal-to-host applications and LAN traffic over a single circuit. 4. The 3512 SDC Bandwidth Expander lets you continue your optimum throughput even when your primary digital leased-line fails. The 3512 SDC Bandwidth Expander features an intelligent A/B switch for optimum restoral at rates as high as 72 Kbps over analog dial circuits or 256 Kbps over switched digital circuits. Since it is unlikely that throughput demands will diminish or that communication budgets will increase, you should investigate the 3512 SDC Bandwidth Expander. Motorola Codex offers a total solution by providing an economical and cost effective digital service up to 256 Kbps at a fraction of the cost of competing products. The 3512 SDC is simple, reliable and economical.

This book can serve as a reminder of the various command and function options. For basic commands, this may be enough: for more advanced items, it can serve as an introduction to the correct section of the program documentation. The book is divided into three sections: User, System Manager, and Installer. The last is a bit brief, being merely a listing of ArtiSoft network interface card settings, and the command-line switches and options for the basic network drivers. The lack of any mention of NDIS is unfortunate. Ironically, the author seems to be extremely proud of the indexing job on the book. There *is* an index, but it is quite brief, and hardly a selling point. Nevertheless, this book is doubtless well worth the price for those working with and managing LANtastic networks. copyright Robert M.

I have been an MCI customer since the initial choose your long distance caller days; we recently had a run in with MCI bureaucracy which has soured us on MCI, and convinced us to change to another carrier. It is truly a case for the books. For some reason, U.S. West or MCI changed the way we were being billed in October. Neither knows why or what happened, and neither will admit to any fault of their own. Rather than receiving our long distance billing on U.S. West bills, MCI begin to bill us separately, or so they thought. We finally inquired why we were not receiving an MCI bill for long distance calls. Nobody would admit to a thing, but conversations with MCI revealed that they had been sending it to an old address -- one we had not lived at for five years. But the drift of the conversation was that we were at fault for not paying the bill we had never seen. They said they would send the bill to the correct address. No bill came. We got a call from MCI Financial Services in St. Louis giving us warning that the bill had not been paid, and that we would have to deal with a collection agency shortly. We told them we had not seen the bill. Not their problem -- they had sent it. I suggested they send it by registered mail, so that at least we and they would know what's going on. Nope, can't do that -- it is your responsibility to pay the bill -- MCI sends their bills by first class mail -- all that is legally required. I even offered to pay for overnight registered mail. No go. Asked to speak with a supervisor, but I was hung up on. Finally got hold of a young man who seemed inclined to listen to what was going on. Yes, he too thought something did not make sense. For a couple of decades, no billing problems, but all of a sudden, one day, we stop paying our bills. But, sorry, it has been assigned to financial services, and there was nothing he could do -- his hands were tied. Only after a very lengthy conversation did we learn that we could pay the bill by credit card (one time only though) by calling a certain number. We have to rely on MCI having the actual amount of the bill correct, because to this day, we have not seen any billing for the two and half months in question. Given MCI's recent performance, we do not have a lot of faith, but did it anyway, just to get rid of them, and the harassing phone calls. My best guess at what happened traces to a $35 billing mistake made by U.S. West last May. That too required several telephone calls, and a copy of a cancelled check with U.S. West endorsement on the back to convince them a mistake had been made. However, the amount kept showing up on our bill each month until October, because, we were told, it could not come off our bill until they found where the error was made! October was the last month we received a billing from MCI on the U.S. West bill, and it was only for part of the month. So, suspicions are that an error made by U.S. West in finally correcting their bill to us created the problem with MCI, and started the dominoes cascading. If this is true, it still does not explain why MCI has things so screwed up, nor why they would screw over what had been a long-time very good customer for them. And I would not bet two cents that this whole ugly episode if over. It's a brave new world -- Kafka must be smiling. Disgruntled, and no longer an MCI customer.

(This is done without specifying a memory location for a stored telephone number.) An example of this is the ability to turn on and off the "15-second beep" which occurs when recording telephone conversations. The user's manual which comes with these phones only contain partial lists of these codes. (e.g., they tell you how to turn the beeping on, but not off.) Does anyone know of a comprehensive list of "hidden features" for various models of Panasonic telephones? Douglas R.

There's a company that offers 12.9 cents per minute on ALL long- distance calling -- both inbound 800's and outbound (1+ calling). When I called them, they told me that this program was available to anyone, be it residential or business phone customers. I don't know what you think of 12.9 cents, per minute, but I was on what I thought was a GREAT business program for my home phone where I was paying roughly 16 cents a minute. By switching to this, my $100 monthly phone bill is going to drop to $80! That's 20 percent savings off what I THOUGHT was a good program. I don't even have to wait until after business hours to get the low rates! This program is 12.9 cents ALL THE TIME, calling to ANYWHERE IN THE UNITED STATES. If you want more information, please reply with your fax number. I saved what these people sent me and would be happy to send it along to you. If you don't have any accessibility to a fax machine, please give me your address and I'll send printouts along to you. Take a look! This is the best long-distance program I've ever seen. Tom Fellrath tdfellrath@delphi.com [TELECOM Digest Editor's Note: Tom, I am wondering why you did not give us the name of the company and their address/phone/fax number so people could contact them directly. By chance, are you a commission sales agent for this wonderful company with their great program? And do you mean to tell me there are no catches at all? No long term contracts, no monthly minimum requirements? Very interesting ... but why don't you want people to contact them directly? Or are *they* the ones that don't want to be contacted directly? ... most MLM programs are like that. Readers, if any of you get anything from Tom on this, please share it.

I really want access to the signaling and call progress info that's available on the digital lines only. Intertel has no clue how this could work (they only know that model X set plugs into model Y port).

Monroe, CT Please reply to: hari@ctr.columbia.edu ------------------------------ Date: Tue, 31 Jan 95 04:03 EST From: bellaire@iquest.net (James Bellaire) Subject: The Cost of Technology I was looking throught the front pages of the local telco directory for Marion, IN (an Ameritech town) when I came across the price list for "custom services." They charge $7.50 for Caller-ID and offer free *67 per call blocking to all customers. I don't want to get into a discussion of how much your telco charges for Caller-ID or any other service. I was just thinking, how much does it cost them? The cost of offering caller ID to the telco is the software that handles the procedure, the hardware that allows that software to work, memory space for that software to reside, maintainance costs for techs that could be fixing something else if CID were not there, etc. Obviously the marketing idea is to spread the capital and upkeep costs across the user base, so a high price for a new service is expected with prices falling when it is accepted and widely used. So cost plus profit = price charged. Now imagine if CID became a basic service, similar to tone dialing. Every line would be given it "free of charge." Of course the basic rate service may need to be bumped up a little in price, since CID does cost the telco something. An area with a 10% subscription rate would need to charge 75c to all customers to 'break even.' An area with a 5% subscription rate would only have to boost the bill 37.5c. So your non-technical "it rings, I answer it and ASK who is calling" neighbors will subsidize the highly technical "my PC VoiceMail takes all blocked and out of area calls; it even blows a whistle and hangs up when I get the CID of teleslease!" type of phone customer. The cost of the software is another interesting question. The telco gets to pay the price set by the writers. How much did it cost the writers? This is where we can get into lots of numbers, including salary for years in development, benifits paid to the software techs, etc. But I digress ... The cost of an item is the price you are willing to pay. The price of the item is set by the person who owns it. If the owner AGREES to give the item to you an a lower price, or free (the best price except when someone pays you to take it from them) you are lucky. And the old owner gets to write down the price he offered you in his income column. If you don't pay the price, you don't get the item. If you take the item without paying the price, you are a thief. And the old owner gets to complain about losing the price he offered you, not his cost, but the price he would have sold it for. If you wouldn't have bought the item at the owners price, even though you disagree with it, IT DOESN'T MATTER. You are still a thief if you take it. If the old owner claims an outrageous price, above that whith they would normally charge, for a stolen item then they are a thief. It doesn't make the original thief any better of a person. Each person must own his own failings, each company its own reputation. If you don't like the way a company does business, go somewhere else. If you can't, buy stock until you can take over the management. Until then be your own person and do right as you should. If another's wrong makes it ok for you to do wrong to them, then your wrong makes it ok for someone to do wrong to you. If you rob the phone company don't complain when someone robs your house, after all your thief was just stealing from a thief that stole from the telco! Something to ponder as you lie down your head tonight. Goodnight, bellaire@iquest.net James E.

For example, cellular operators of CT2 standard. Since I'm a kind of 'newcomer' in providing telecom services (cellular) I'd like to know how it works in the sharing methods between two /more operators. That question relates to these subjects: 1. Operation; 2. Project; 3. Interconnection Agreement; 4. Charging / Billing. Illustrations: 1. Operation: The building and maintenance of the base stations Is it 50 - 50 or other method? 2. Interconnection Agreement: suppose subcribers of other operators use 'our' base stations while those operators do not have agreements with us. What's the common method used to solve this kind of situation? 3. Billing / Charging: in case there are 'flat rate users' and 'pulse rate users'. Please reply to 'aries@asterix.bppt.go.id' since we don't have 'direct' news service, yet. I'm particularly interested in providing CT2 service. Many many thanks in advance! If you have any useful information about CT2, it will be very helpful.

From the post below relating to the problems the FCC is having just enforcing its laws/regulations against actual pirate broadcasting, is there anyone that can even perceive the FCC has any resources to worry about the thousands of people using and/or modifying radio scanners to receive cellular telephone broadcasts? I think not. As before, don't kill the messenger. I point this out to illustrate the practical side of life and the law as opposed to those that suggested illegal activity was going on by modifying radios. Bottom line is ... no one cares, least of all the FCC. Begin post from misc.legal.moderated newsgroup In another newsgroup, Stephen Dunifer (frbspd@crl.com) wrote: Victory for Micro Power Broadcasting - Historical Defeat for the FCC On Friday, January 20 Federal judge Claudia Wilken refused to grant the Federal Communications Commission a preliminary injunction to stop the micro power broadcasts of Stephen Dunifer and Free Radio Berkeley. Stating serious constitutional concerns as her reason, Judge Wilken denied the request, ordered the FCC to exhaust administrative remedies and to rule on Dunifer's appeal of their $20,000 fine before seeking any further court action. This ruling sets a historical precedent: it is the first time the FCC has been denied an injunction to stop the broadcasts of an unlicensed radio station. The Commission will have to address the issue of the constitutionality of their regulations when ruling on Dunifer's appeal. Any further court proceedings are delayed until the FCC acts on the appeal which has languished in Washington for more than a year. In the meantime the government's attempt to enjoin broadcasting by non- licensed micro radio has been put on hold. Luke Hiken, attorney for Stephen Dunifer, stated, "This is the second time a Federal court has recognized the constitutional implications of micro radio technology. We hope the FCC will recognize the importance of facilitating the use of this technology for the benefit of the American people instead of denying its existence and obstructing its use." Speaking on behalf of the National Lawyers Guild Committee on Democratic Communications, Peter Franck commented, "The CDC hopes that the court's refusal to enjoin micro radio is the beginning of a recognition by the country that any hope for democracy depends on free access to the airwaves. Micro power broadcasting has the potential for creating a 'green movement' of low-cost, easy-to-use media. It is as totalitarian to require expensive, hard-to-get licenses for micro radio as it would be to say you can only speak from a soap box if it is made of gold." Stephen Dunifer said, "Judge Claudia Wilken's decision affirms the validity of our legal position. Further, this victory is a credit to four years of work by the National Lawyers Guild Committee on Democratic Communications and my attorney, Luke Hiken, on behalf of the micro power broadcasting movement. Unlike FCC attorney, David Silberman, I do not see irreparable harm resulting from micro power broadcasting. Instead, I see an immeasurable benefit for all citizens if the micro power broadcast movement prevails. For too long, media access and the tools of communication have been concentrated in the hands of corporate and essentially anti-democratic interests. If any harm results, it will be to those monopoly interests." For further information contact: Free Radio Berkeley - (510) 644-3779, (510) 464-3041 or Luke Hiken, attorney at law - (415) 705-6460.

I would like to prove it once and for all. It occurred to me that a modem sending a steady carrier such as is used to establish a 300-baud connection would be a perfect signal generator. It could be placed on a line off-campus and then called from on-campus. An oscilloscope placed on an analog campus line should show clock slips as sudden phase shifts in the carrier. Is this a valid test? If so, we could show the phase shifts through such a line and then demonstrate that no such problems occur on campus or between two Southwestern Bell lines. Any suggestions are appreciated since the feeling is that there is really nothing wrong because the lines all sound clean and voice calls don't get dropped. With a 2025hz tone, a clock slip should advance or retard the carrier 90 degrees which should truly destroy the phase component of a data transmission.

One could purchase it, have it authorized, and pay no monthly fee. If one used it, they paid a fairly high per minute airtime that was automatically charged to a major credit card.

Cotroneo) Subject: Ericsson GH337/EH237 Cellular Modem I/F Date: 31 Jan 1995 14:56:13 -0600 Organization: UTexas Mail-to-News Gateway I am looking for information on availability of cellular modem I/F for the Ericsson GSM GH337 model, and for the European TACS version EH237. For both models the modem I/Fs are not apparently on sale (yet) on the Italian market. An Italian reseller also told me that in it is not possible (yet?) to operate any modem/data communication over the Italian GSM network; I made some experiment myself sending a modem signal over the voice channel, but had no success, apparently for the losses induced by the quantization/compression on GSM. I would be most interested in knowing your experiences -- good or bad -- with the use of the GSM version of this phone, for both voice and data (?).

Thanks, Alfredo Cotroneo Milano, Italy ------------------------------ From: dreuben@interpage.net (Doug Reuben) Subject: Metro Mobile (CT/RI/MA) Added to the NACN Date: Tue, 31 Jan 1995 13:23:46 EST After years of holding out, Metro Mobile CT/RI/Western and Southeastern Mass (collectively known as Bell Atlantic's Northeast service area) has been added to the NACN. The NACN, or North American Cellular Network, is the A-side's automatic call delivery service, initiated by McCaw Cellular and some of it's roaming partners, to provide increasingly seamless coverage throughout the US and Canada. Prior to Metro Mobile's addition to the NACN, Metro Mobile CT and Western Mass customers had the use of most of their features as well as call-delivery to Cell One/NY, ComCast/NJ-PA-DE, Metro Mobile/RI-SE Mass, Cell One/Boston, and CO/Boston's Concord, NH "partnership" service with Atlantic Cellular. So the addition of the NACN won't make too much of a difference in terms of added coverage near Metro Mobile's territory. Moreover, Metro Mobile, unlike CO/NY, will assess a roam charge for most (all) markets outside of it's properties, Boston, and NY. Additionally, the link between NY and CT (and everywhere else) seems to lack the functionality of a typical NACN link. I've noticed that ALL features normally available to a customer on his/her home system are also available on a visited system (although some switches won't allow this.) Thus, Cell One/Boston customers can *successfully* set up and remove voicemail from most NACN systems, as well as get call-waiting, yet on Metro Mobile's switches, the same Boston customer will find that none of these features will work. Additionally, Metro Mobile customers roaming in NY can not, for example, forward calls to voicemail, selectively unforward unconditional forward calls (by using *723), etc., even though these same features are currently available to Boston customers roaming in NY, and even though both Boston and CT use the same type of switches (Motorola EMX-2500). I've asked CO/NY for years to put in the *723 code so I could use forwarding in NY without killing voicemail, but they were never able to implement it, so it seems as if the same old link to CT is still in place, but somehow Metro Mobile is now "on" the NACN in some limited way. (If they were "fully" connected, I'd expect to be able to use my features in NY or SF or wherever to the same extent that I can use my Boston them from my Boston account.) Additionally, the standard NACN Do Not Disturb codes (*350/*35) will NOT work in NY, instead, the older Motorola codes (*28/*29) are required. In any event, this finally allows most roamers to get automatic call delivery in the Rhode Island system, which has been slow to get any connectivity outside of Boston and CT in recent years. Any NACN customer should now be able to receive calls in RI, use (some) features, etc. RI customers should now be able to receive calls in NY, although they will pay a $3 daily and $.99 per minute. If you are a RI customer, and roam into NY a good deal, get Boston account, which offers no daily roam charge, and 44 peak/29 off-peak. You still have to pay Boston's outrageous home airtime for call-delivery though. Maybe just get a NYNEX account instead and be done with all these silly charges from Metro Mobile and Cell One/Boston, both of whom seem to want to nickel and dime their customers as much as possible. (I still can't see how Boston customers put up with home airtime charges, plus roaming charges, plus a daily roam charge, plus a $2 Boston charge, just to receive phone calls! :( ) Note that Metro Mobile's addition and lack of some features does NOT affect Litchfield, CT, which has been on the NACN since October 1994 (or earlier), and seems to be run through CO/NY's switches. (They are both McCaw owned and have the same messages on their switch/error announcements.)

As I am an agent of the company which owns the technology, I wanted to get their OK before releasing information. They have given that OK. Here is a brief summary: (note that I'm a layman and not a techie) The Call Control System CCS is a controlled access gateway which provides an additional layer of security to the fraud vulnerable components of a PBX system. By validating the call origin using the Calling Line ID (CLID) and an authorization code, the CCS limits access to the DISA ports, maintain- enance ports and voice mail systems of a PBX. The CCS is a combination of Canadian software and hardware. There are three components to the system: Call Control Manager (CCM) software; System Administration Manager (SAM) software; and Call Control Interface hardware. The intial application was developed for a long distance reseller. To date this application has not had any unauthorized access. The traffic runs over 15 million calls per month. The company that developed the system is now offering the technology to the general narketplace. Acquistion cost to users will run in the $20,000 range for the system. This is the general concept. If you would like to know more, I would be pleased to follow up. We think this product will have appeal in the US market (and anywhwere else that phone fraud is a problem) and would be pleased to have your feedback, etc ...

Before switching to GSM I had a NEC P3 (ETACS version; the same system that is used in UK and Austria too) with a Hands-Free-Kit and external antenna. During installation of the new Nokia phone I connected the existing antenna, that always had worked fine with my NEC P3, to it. When making phone calls everything works fine if I use the handset but in case of using the hands-free option the called or calling party on the other side hears some very loud interference-like sounds mixed together with my voice. First I thought that the hands-free section of my phone would be defect but then by case I tried to turn off my antenna leaving the antenna cable connected to my phone and surprise, surprise, everything was perfect. I called Nokia Customer service but their representitive did not understand very much about GSM phones as they are still not very popular here in Italy. For now I attached a small FM-antenna to cover the ugly knob that comes out of my trunk, but I'm afraid to burn my amplifier (8W) without a proper antenna. Who has any idea of what happened and what I should do? Please e-mail to morhofer@heavyfun.com.

Well, AT&T completed the call today (the local switch has been accepting 1-500-367-XXXX for sometime) and the only billing option was calling card. Well, I tried that, and someone other than me answered the phone. I have no idea who it was, but I guess I'll have the number when I receive my calling card bill! Matt :) [TELECOM Digest Editor's Note: Well, you have gotten a lot further with it than I have here. My 500 number was supposed to be turned on yesterday, January 30. Still no go as of Tuesday evening, January 31. The AT&T rep suggested calling the Illinois Commerce Commission and asking them to ask Ameritech to unblock 500. A call to the ICC got me the response that 'so far as they knew' (the ICC), there was nothing yet tariffed for 500 here. AT&T said try using it via 800-225-5288 (CALL-ATT), but guess what? That didn't work either. Since my long distance service is defaulted to AT&T I tried double zero, and ask the operator to get it for me. After asking someone what to do, she tried dialing it and it went nowhere. She said it was 'blocked' in her computer and would not 'leave'. I am sure the AT&T billing department is more effecient and that I will be billed for this month anyway, just as I was for last month. :( PAT] ------------------------------ From: r_cayne@pavo.concordia.ca (Richard Cayne) Subject: AudioText Applications Date: 31 Jan 1995 09:23 -0500 Organization: Concordia University Please send details on audiotext applications currently in use by retailers to better serve their clients.

It Our first set was a '46 model, as I recall. It was an RCA with a screen about eight inches diagonal, in a cabinet about three feet long, a foot and a half deep, and about the same height. If memory serves, it weighed about 100 pounds -- but by the standard of the time, RCA called it a "portable". It was one of very few sets I've ever seen with channel 1 on the tuner. That channel space (44-50 MHz) was originally intended for low-power stations to serve smaller towns, but was quickly taken away for FM broadcasting, which was then moved to 88-108 MHz. > Five digit numbers were common in communities which had automatic dialing > systems in those days but only one exchange in the community. Since the > exchange name was always the same, it was assumed when dialing. In your When we moved to a new house in Washington, DC, in 1953, we still had a six-digit number (actually 2 letters/4 digits: KEllogg 1528), but very soon after it received an extra digit and became KE7-1528. Ten years later, my parents retired and moved to a little town in the western "corner" of South Carolina. They had a modern seven-digit number (646-nnnn, previously released as MIlton 6-nnnn: I have no idea who "Milton" was), but since the entire town was on the same exchange, only four digits needed to be dialed to reach anyone else in town. I don't believe seven-digit local dialing became mandatory until about 1970. Dale Neiburg, STC National Public Radio Phone: 202-414-2640 635 Massachusetts Ave., N.W. Washington, D.C. 20001 Internet: dneiburg@npr.org [TELECOM Digest Editor's Note: Channel 1 was gone from television sets by around 1949-50 I guess. There is a national organization which provides educational (but some say infomercial) television to school students on closed circuit called 'Channel One'; you may have heard of them. I have a General Electric portable color television which still goes up all the way to Channel 83; so you can guess how old it is. Most folks are unaware there is a HUGE gap in the frequency spectrum for television between Channels 6 and 7. Where Channel 6 ends at about 88 megs, Channel 7 does not start until about 175 megs, way up in VHF. About thirty years ago when FM radios were still sort of new (they had been around for twenty years, but not for over fifty years like now) a religious station called WYCA went on the air in Hammond, Indiana, around 88-90 megs someplace. We have discussed *them* here in the past, a few years ago when thier station was the cause of many complaints to the FCC. In those days, around 1962-63 they had the nerve to tell people, 'if you do not have an FM receiver, you can still listen to the Word of God daily on this station by putting your television set on Channel 6 then moving the fine tuning dial until you hear our signal.' How's that for brass? By the way, 'Milton' was Milton Berle, one of the first people to appear on your 1946 television set.

Well, I've been following this and some of the other related newsgroups for a while, and I've finally decided to try to pick a good LD carrier to cut down on my LD bills. I use about $60+/mo. in LD for one residential line, so I don't expect any earth shattering savings, but I figure that I shouldn't pay any more than I have to. I know from reading articles here that I can do much better than the big three, and I realize that I'll have to do a little leg work for this. The big problem is that I'm not sure exactly what I should be looking for, specifically what questions to ask and what pitfalls I should look out for. I've heard of LD resellers, six second increment billing; are there any other important issues? Should I be concerned with who the resellers are reselling from? Is there a good starting point for finding LD carriers that don't advertise much (my Yellow Pages lists only two companies in the Long Distance heading)? How about LD calls not carried by my LD carrier (i.e. in my area code, covered by Bell Atlantic)? Is there anything that I'm not asking that I should be? Also, I'll be adding a cellular phone soon, and is there any way that I can get a better rate by virtue of having two accounts with an LD carrier? Thanks in advance for any information that anyone can provide. Steve Chinatti [TELECOM Digest Editor's Note: I would refer your questions to that genius Marilyn Von Savant -- the smartest person in the world with an extremely high IQ whose column appears each week in {Parade Magazine} -- but the last time someone asked her the same question you are asking here, namely which long distance company to pick, she admitted that even she was unable to answer that one. Put the names of several carriers in a hat. Close your eyes, reach in and pick one. Live with it for a few months, then try one of the others.

Local should be charged higher because it is expensive. You provide unlimited free calling for a flat fee instead of charging on a call by call basis. Of course you lose money. Local access charges are profitable, and are on a call by call basis. LEC's don't want to lose that revenue. With bypass and local exchange competition it could be tough. Remember the costs associated with access. A LD call is dialed (say international), the local switch has to do all the work to validate the number and then pass it off to the pick. The pick "just routes" a number. (oversimplification.) But the LEC doesn't get paid for all the incomplete calls, all the dial back calls, etc and that costs money. So local service pays for itself (barely) and profit comes from access charges which is also an expensive proposition. (Some local companies, especally rural, don't even handle long distance. They just pass it off to someone else to do.) There is verification, routing and don't forget billing to do. It is expensive.

I have several wooden coat hangers that I inherited with four or five digit numbers of the dry cleaners on them, probably from back in the 50's. Then later, all the phone numbers were five digits preceded with NEwmark as the word. Now they are just 63x-xxxx. > TELECOM Digest Editor's Note: > Does anyone remember when all the military bases around the USA had > their own special arrangements?

PAT] I worked on a switchboard when I was in Gernmany, and I remember the Autovon lines that we had. I don't know why, but they were always low in volume. They worked but everyone had to yell in the field phones to get thru. Maybe that's why they were so weak: because the phones were field phones. We had phantom lines that were weak, but some were better than the Autovon lines. Then there were the lines that were on the microwaves from missile site to missile site. They were always hollow sounding or singing. I'm glad that things are a lot better nowadays. I really hated getting stuck with that stupid copperweld steel field phone wire.

Five-digit numbers were once quite common for dial service in all but very large cities. It wasn't that "Wilmington" was understood; that was the whole telephone number, and it was in Wilmington. Since there all dialing was local, the concept of a name or prefix didn't exist. For long distance calls, you reached a long distance operator, told her what city and what number you wanted, and she plugged into either a ringdown or straightforward trunk to the inward operator in that city, rang on it, if was a ringdown trunk, and passed the number to the inward operator by voice when she answered. The inward operator dialed the number (typically with a rotary dial on the keyshelf) to connect with the desired number. (If there were no direct trunks to the called city, the operator had to go through other cities on the way to get there; routes to popular destinations were on a keyshelf bulletin; if not there, she connected to a rate and route operator and inquired as to the route.) > Does anyone remember when all the military bases around the USA > had their own special arrangements?

PAT] The military bases were probably classified as exchanges for toll purposes and so you reached them over a toll trunk, same as a long distance call to any other exchange. Military bases always had special arrangements for connecting to both the exchange and toll network and had their own operators (and switches, where the military post had dial service). But talk of the newspaper in Wilmington and unusual arrangements reminds me of the time when I was working for The Daily Oklahoman in Oklahoma City (2-1211 and also L.D. 343; do you remember toll terminals?) and I had occasion to call Phillips, Texas, about a fire. Phillips was a company town of a Phillips Petroleum Company subsidiary near Borger, Texas, where they had one or more chemical plants. I had the number in Phillips and I placed a call with the long distance operator. She went to rate and route (see above) who gave her the routing of "TC Borger" (toll center Borger). So she connected with Borger and asked for Phillips. The inward operator responded "your ticket reads Borger 666, a PBX." So this was a case where it really was a PBX with extension numbers. This was probably around 1949 or 1950. Wes Leatherock wes.leatherock@oubbs.telecom.uoknor.edu wes.leatherock@f2001.n147.z1.fidonet.org [TELECOM Digest Editor's Note: This reminds me of when the operator in North Bay, Ontario was the inward operator for all the little towns northward along Imperial Highway 11, clear up to Hearst. When you called any of those points, the long distance operator always got a report from Rate and Route which indicated North Bay. So your operator dialed something and presently there came a response over the wire "North Bay!" and your operator would ask for the number in Hearst, for example, but the other end would say 'just a minute, I will ring the operator in Hearst for you and you give her the number you want.' You'd hear this 'kerchunk' sound as she was ringing, and sooner or later "Hearst" came on the line to ask for 'number please?'. That is, unless you called after about 10 pm at night ... call that late, and North Bay had a different answer for your operator, who seemed astounded to hear such a thing: "Is this an emergency call to Hearst, Ontario?" (your operator would repeat the question to you, and you would say no.) "Well operator, we are not supposed to ring her after ten o'clock at night unless its an emergency. She goes to bed at ten. If it's an emergency I will ring her, but we are not supposed to call until after seven in the morning. Seven is when we give her a wake up call." Then there was Alma, Quebec. Alma served as the inward for several places in the far northern reaches of Quebec but connections were made over *AM radio links*. Rate and Route would give your local operator the notation 'other place' to mark on the ticket and a number to dial which reached Alma Inward. If your operator thought it strange that the 'phone company' in Hearst closed down overnight, she thought it even stranger when the operator in Alma answered, always first in French then immediatly in English saying 'Alma Radio'. Your operator would ask for one of those places and the Alma operator would answer almost indignantly: "oooh! madamoiselle! They are not going to answer me now! They only promise to listen to zee radio between seven and nine oclock. Do you want me to try anyway? Maybe they will answer." So giving it a try, she would go on the radio circuit from her switchboard and with sometimes horrible static in the background when she was not transmitting, she would try to raise them. First in French then in English over and over, four or five times calling for whatever small village it was 'this is Alma on Channel 1, do you copy me'. Then she would go try on Channel 2. Finally she would say there was no response from them, and almost as an afterthought, 'madamoiselle, where are you calling from?' The operator would tell her she was in Chicago. "Shee cah go? In zee United States? Operator, you call me back at seven o'clock, I will see that they talk to you then." Long ago times, indeed. That would have been in the middle 1950's.

Just to add another piece to the puzzle: in Canada the Norelco trademark was not owned by Philips but by The Northern Electric Company Ltd., which made radios, wire and cable, telephone equipment, and even appliances like refrigerators. Northern Electric was majority owned by The Bell Telephone Company of Canada (now Bell Canada), and was renamed Northern Telecom in the mid 1970s. It is now best known for its DMS switches and related telecom equipment. In Canada, the Philips electric razors and such are sold under the Philishave name.

Check the numbers and see how the costs look for a period of time, and you might be saving a lot real quick. If you can use some groups of 24 circuits, then T-1 gear could be another answer to saving some money. Or instead of running your own cable, you could run fiber instead. Or radio gear could also eliminate the dependence on the telco altogether. I would get one of the above and implement it, and not go completely independent of the telco until I was sure that the fiber or radio was going to be a reliable substitute. Maybe keep 1/3 of the telco lines just in case.

PAT] I think here in Pac*Bell land, the Calif PUC requires that if the subscriber had a loss of service greater than 24 hours, they can remove the loss from their bill. Like if the phone is out two days, they can subtract 2/30 of a month's bill. Of course, that doesn't include other charges like toll calls. So if you get service on the 30th, you might be able to get away without paying the loss between the 24th and 30th. I'm assuming that the regulatory laws are somewhat uniform from state to state.

It covers the concepts of encryption, public key encryption, authentication and key management, as well as the installation and operation of PGP on MS-DOS and Macintosh platforms. There is also some overview of front end shells for DOS and Windows, plus helpful supplementary information on password/phrase choice key servers, and where to get PGP. (The promise of coverage for Windows, UNIX, OS/2 and Amiga in the promotional literature is overkill, but these interfaces will be almost identical to those covered.) Stallings' material is generally very clear and well written. Many times, however, concepts are introduced early in the book but not explained until much later. This is particularly true of key management. In most cases, I can assure the reader not to worry -- all will be made clear, eventually. (In some few cases, the explanation may remain confusing until you actually run the program.) The book echoes the assertion by many that PGP has become the de facto standard in Internet privacy and authentication. Certainly no commercial product has anything like the same range of use. Full acceptance of PGP, though, has been hampered by the version incompatibilities and the legal difficulties caused by the US weapons (!) expert control laws. Given the touchy nature of this subject, it is not terribly surprising that both Stallings, and Michael Johnson in the access document, comment only briefly on the subject. These passages are somewhat calming, but hardly calculated to inspire confidence. Solid background on the technology, if sometimes disjointed. Terse, but serviceable documentation on the program.

Given the development of international telecom alliances and their provision of specialized services for business, I am wondering about the extent to which telecom carriers would be liable for lost messages, contracts, product ideas and the like. [I realize that in general, telecom companies are protected from such liability and that international tariff agreements also protect carriers. But given the fact that the carriers know or ought to know the importance of these networks to business, doesn't the carriers' exposure to risk increase?] Assuming that there is carrier liability for these problems, where would such liability be prosecuted? Would it be in the originating country? The terminating country? Or where the breach occurred? Or is this question redundant because service providers expressly contract out liability? Any help that can be provided in this matter would be greatly appreciated! Thanks in advance! David Ujimoto d.ujimoto@utoronto.ca ab261@freenet.toronto.on.ca [TELECOM Digest Editor's Note: A few years ago Illinois Bell had that awful fire in Hinsdale, Illinois which knocked much of their network off line for several days and some of it was off line for almost a month. They claimed they had no liability to subscribers for lost business as a result of the outage, and for the most part they were backed up in this opinion by the court when various subscribers sued them. I think telco's contract with you -- which is the tariff -- says telco's liability is limited to the amount of money you paid for service which they were unable to provide.

Some feature communications system. Telecommunications software is huge, real-time, and distributed; adding new features to a telecommunication system, like adding new functionalities to any large software system, can be very difficult. Each new feature may interact with many existing features, causing customer annoyance or total system breakdown. Traditionally, interactions were detected and resolved on a feature by feature basis by experts who are knowledgeable on all existing features. As the number of features grows to satisfy diverse needs of customers, managing feature interactions in a single administrative domain is approaching incomprehensible complexity. In a future marketplace where features deployed in the network may be developed by different operating companies and their associated vendors, the traditional approach is no longer feasible. How to detect, resolve, or even prevent the occurrence of feature interactions in an open network is now an important research issue. The feature interaction problem is not unique to telecommunications software; similar problems are encountered in any long-lived software system that requires frequent changes and additions to its functionality. Techniques in many related areas appear to be applicable to the management of feature interactions. Software methodologies for extensibility and compatibility, for example, could be useful for providing a structured design that can prevent many feature interactions from occurring. Features are typically design to suit the purposes of a user or business, hence Enterprise modeling will play a role in the identification of certain classes of interaction, in particular the solution of an interaction in one enterprise may not be desired by another. Formal specification, verification, and testing techniques, being widely used in protocol engineering and software engineering, contribute to the detection of interactions. Several causes of the problem, such as aliasing, timing, and the distribution of software components, are similar to issues in distributed systems. Cooperative problem solving, a promising approach for resolving interactions at run time, resembles distributed planning and resolution of conflicting subgoals among multiple agents in the area of distributed artificial intelligence. This workshop aims to provide an opportunity for participants to share ideas and experiences in their respective fields, and to apply their expertise to the feature interaction problem.

I did what I normally do when I don't recognize an exchange, which is to dial NXX-9901. In NYNEXland, this will usually tell me the name of the C/O, and I can then judge if it will REALLY be a local call. To my surprise, here's what I heard when I dialed 393-9901: "Hello, You have reached the Cablevision Lightpath 5-E switch, serving the 516-393, 439, and 465 Exchanges" Cablevision, the local cable tv operator was written up in Long Island Newsday last week as major local competition for NYNEX. While they said that Cablevision already had its own switch installed, I didn't realize that the changes were already made!

Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Wed, 1 Feb 1995 05:03:28 GMT I heard a very brief report on one of the local radio stations that Southern Bell was planning to increase the size of the "local Atlanta calling zone by 50%" by "adding 34 new exchanges" to it ... Of course, no further details were given, such as: will Southern Bell raise rates for everyone in Atlanta? (probably) ... where are these 34 exchanges (any 706 exchanges)? ... etc. I have a feeling that this is an effort to bring all of 404 into a single, toll-free calling zone, which it virtually is already ... there were several exchanges that were originally slated for 706 at the time of the 404 split, but were eventually brought back into 404 by public uproar. Perhaps this where the "34" figure comes from, although I didn't think there were so many. Anyone have more details? Thanks!

Date: Wed, 1 Feb 1995 02:16:08 EST I was at a meeting at the Ameritech HQ in Ohio the other day and I left the meeting for the rest room, and noticed that near the lobby/cafeteria there was a display of various Ameritech novelty items (T-Shirts, mugs etc and other corporate propaganda) and also in the case were a couple stickers for sale. All of these items were 'for sale' but no one around to buy from, so hence my question. I noticed a couple decals for sale that were in the shape of a triangle, wider than tall, blue with white lettering, seeming to commemorate (judging from the old style of graphics on the decal) some organization called the 'Telephone Pioneers of America' (I think that's what it was called). What is this organization, or was it, as the case might be? A boy/girl scouts for the telephone company?! Of what? As someone who has been getting a lot of hands on experience in the problems of rural internet connectivity these days (in SE Ohio for the South East Ohio Regional Free-Net) I have become fascinated with the history of the telcos, the history of the acceptance in our lives of a machine that we talk to (which in my opinion is almost as absurd as a machine that we watch for at least six hours a day!). Anyway, this looks to be an interesting bit of tele-trivia, if anyone has the answer. I didn't get the chance to ask Ameritech, I'll try to find out at the next meeting. Thanks, Jonathan Prince Rural Action - VISTA for the South East Ohio Regional Free-Net aa078@seorf.ohiou.edu [TELECOM Digest Editor's Note: I will give you the answer, and it is not 'trivia' in any sense of the word. And please don't stand up at the next meeting to ask who are the TPA, because chances are everyone in the room would be embarrassed for you. I know I would be. For your information, the Telephone Pioneers of America is an outstanding organization with chapters at telcos all over the USA in the Bell Operating Companies and at AT&T. At the non-Bell telcos, the same organization exists known as the Independent Pioneers. TPA has been around for close to a century now. In the very early days, meaning the period up to about 1930, the TPA was composed of people who had been employed by (what was then) the Bell System since its beginning. They were, in effect, the 'charter employees' of the company, or 'pioneers' in telecommunications. They were the people who started what you take for granted today. As time went on into the 1920-30's, most of those old pioneers were either dead, retired or on the verge of retiring from Bell after forty plus years of employment with AT&T. The organization then amended its charter to allow membership by any employee of AT&T or (as they were called) a subsidiary company who had been employed by Bell (or an independent) for at least twenty years. I believe that rule still is in effect, although many chapters of TPA have associate membership programs for employees with less time on the job. What do they do? What is their purpose? They are very involved citizens in their communities. In their spare time they devise solutions to the problems encountered by differently-abled (I used to say 'handicapped' but this is now a politcally correct Digest, since I want to have it distributed on several major campuses) persons. They have developed methods by which someone who was completely paralyzed could 'talk' on the phone using a pencil they held in their teeth. They have developed all sorts of gimmicks and gadgets for very limited use applications by people who for whatever reason could not otherwise use the phone. Aside from their marvelous work in specialized telecommunications applications for handicapped people, they are good citizens in their community. They assist with voter registration. They work with people who have AIDS. They take food to old people who can't get out of their houses. They record books and newspapers on tape for people who are visually handicapped. They are helping to restore telecom links in Kobe. To be honest with you, I don't know what some chapter of TPA *doesn't do*. Most of their expenses come out of their own pockets. The telcos make corp- orate contributions, and they raise money through the sale of 'corporate propoganda' such as coffee mugs an T-shirts with their employer's logo on them. There are, you see, some people around who are proud to be employed by telco and who like having artifacts of that sort in their home, etc. And that's the Telephone Pioneers of America: a splendid bunch of people with a long and positive role as leaders in telecom.

It is still the case that you can pick up the 88-90 MHz FM broadcasts on a TV with a good 'ol analog tuner. Similarly, you may be able to tune in many pager services and cellphone con- versations (or often, more precisely, their IF images) on the upper reaches of your old UHF TV. Here in LA the wide bandwidth of a TV tuner is a disadvantage when doing this, as many cellphone frequencies conversations fall in the bandpass at any given time. In more rural areas, this is not nearly as big of a problem. I'm waiting for the FCC/phone cops to discover this and ban the sale of older TV's at yard sales. I don't think they are currently banned, as they are not exactly "scanning receivers" -- or has the law been broadened recently? Tim Shoppa (shoppa@altair.krl.caltech.edu) [TELECOM Digest Editor's Note: Yeah, well you can't really get cell phones on your television (in the upper UHF channels now abolished) very well. The innards of the television are different as you point out. You can set the dial up there on channel 81-83 for example and twiddle the fine tuner all you want. You just get bizzarre bits and pieces of things, not even as much as you get on a scanner. I realize you were to some extent joking but I'd not get too concerned.

BELL URGED TO CUT PHELPS' CHURCH PHONES By STEVE FRY The Capital-Journal A prominent Topeka businessman is challenging Southwestern Bell to pull the plug on telephone service to Westboro Baptist Church because of what a local lawyer calls the "defaming and harassing" faxes that emanate from there. Kent Garlinghouse chief executive officer and chairman of M-C Industries Inc., has joined with lawyer Jerry Palmer in condemning the telephone company for not acting to curb the fax messages of Westboro Baptist Church. The faxes are sprinkled with words such as "fag," "sodomite," "pig" and "whore." The pastor of Westboro Baptist is the Rev. Fred W. Phelps Sr. Its congregation is composed primarily of members of his family. The congregation is best known for its anti-gay picketing. The picketing that began on local street corners has increasingly turned up in locales across the nation, drawing widespread media attention. Garlinghouse said the picketing has become so embarrassing he is reluctant to acknowledge he is from Topeka when he meets people while out of town on business. He and Palmer contend it is Southwestern Bell's civic duty to take action against what they deem is an abuse of telephone service. "I think Southwestern Bell has been a bad corporate citizen in their failure to use the power they have to abate the serious problem this community has with these defaming and harassing faxes," Palmer said. "They're like the rest of the community. They're afraid. They don't want the litigation, the hassle" with the Westboro church, Palmer said. Many of Phelps' 13 children are lawyers. "Southwestern Bell could -- today -- shut off the fax service to Westboro Baptist Church if they had the will," Palmer said Wednesday. Anne Marie Hilday, a Southwestern Bell spokesman, said the matter boils down to a First Amendment issue. "Southwestern Bell is a good corporate citizen because its efforts are aimed at serving its customers fairly and without discriminating against any customer," she said. "However, Southwestern Bell cannot act as prosecutor, judge and jury in determining whether conversation between two persons is defamatory and libelous or otherwise illegal." Garlinghouse said he hasn't been the subject of a Westboro fax, but was cursed by a church picketer as he entered a west-side restaurant Sept. 17. There are more issues than just the church`s faxes, Garlinghouse said, including church picketers on Topeka streets, entertainers shunning Topeka and harassment of Topekans attending public performances. Palmer contends the phone company could shut off service based on a Kansas Corporation Commission regulation linked to abuse of telephone service. In that regulation, there is a section dealing with calls directly to a person that reasonably could be expected to frighten, abuse, torment or harass that person. Southwestern Bell's Hilday counters that the regulation is applied within the law. Palmer said the regulation should be extended to third parties. For example, if A sends a fax to B about Z, the regulation should protect Z, Palmer said. On Aug. 11, Palmer filed a complaint with the KCC saying existing regulations against abuse of telephone service by voice communication are inadequate to cover abusive facsimile messages about someone who doesn't actually receive the fax message. The phone company contends updating the regulation isn't needed and urged the KCC to drop its investigation. Palmer, a longtime Phelps target on picket signs and faxes, represents St. David's Episcopal Church in a civil lawsuit against Westboro. Instead of cutting off phone service, Southwestern Bell is using the criminal prosecution route, which is quicker than a civil suit or administrative action, Hilday said. Southwestern Bell can place a "trap" on a phone or fax machine to trace the number of the fax sender. After three offending calls are received, the information is turned over to law enforcement officers, who visit the sender to talk about the complaint. If the fax messages continue, officers can seek prosecution for violation of the regulation. Upon conviction, the phone company can disconnect the offender's phone service. So far, 14 customers have complained to Southwestern Bell about the Westboro church faxes, Hilday said, but none has agreed to use the trap method. The problem with the trap method is it could make the complainant a target for more fax messages, Palmer said. Even though the complainant wouldn't receive future messages about himself, many outlets for the messages would, Palmer said. By using the regulatory route, everyone benefits because Westboro fax messages would end, Palmer said. Using a trap to identify the Westboro church as the fax sender is "absurd," Palmer said. "That leaves Southwestern Bell, probably, as the only people who don't know where the faxes are coming from," he said. Westboro faxes usually have church logo at the top or are signed by Phelps, Palmer said. In October, Shawnee County District Judge Michael Barbara found Phelps in contempt of court based, in part, on a fax issued by the minister, Palmer said. It isn't clear when the KCC will complete its investigation of Palmer's complaint, said David Schlosser, KCC spokesman. Researchers are trying to determine whether other states offer third-party protection. "I think it's embarrassing," Garlinghouse said of the Westboro anti-gay campaign. "It does not make me proud to be a Topekan. It's amazing how many people around the country are familiar with the Phelpses.?' From The {Topeka Capital-Journal} Editorial Page Sunday, January 22, 1995 Phelps faxes: Bell, it's your call. Sidebar: Some believe the phone company has the capacity to pull the plug on the cult of contempt's faxes Sidebar: This is not free speech. It is high-tech harassment. It is reaching out and touching someone with defamation and mass character assassination. If you feel Southwestern Bell should stop this madness, call the company and tell it to. Southwestern Bell, you have been duly challenged. It's your call now. Several knowledgeable Topekans believe you have the power, the right and, indeed, the obligation to end the torrent of scornful, libelous fax messages sent by the Westboro Baptist Church over the last few years. The challenge is this: Do you stand up for your customers, for the law, for Topeka and for decency? If so, you won't stand alone. The community will stand with you. To those few fortunate ones who have escaped viewing the faxes from Fred Phelps' family: You just would not believe the mean-spirited bile that flows from Phelps' church through area fax machines -- reckless allegations of sexual improprieties and other misdeeds, public and private; doctored cartoons and other copyright infringements meant to embarrass particular individuals; and name-calling and threat-making intended solely to terrorize. This is not free speech. It is high-tech harassment. It is reaching out and touching someone with defamation and mass character assassination. And it must stop. Some of the victims are public officials. Some are community leaders. Still others are private citizens with the misfortune of being discovered by the Cult of Contempt. Most importantly, they are all human beings. They don't have to live with this. The Phelpses have an absolute right to wallow their lives away in the sewer of their creation. But the good people of Topeka have no such obligation. The good people of Topeka have a right to peace and harmony. The local band of haters is disturbing that peace in every way it can, taking glee in each new wound it makes. But it is now time for healing. Some, including local business owner Kent Garlinghouse and attorney Jerry Palmer, say Southwestern Bell can begin the healing process. They believe Bell can and should prevent further abuse of its telephone customers by discontinuing phone service to Phelps' church. The question is not whether Southwestern Bell is a good corporate citizen. It is. The only question is, can it be better? It just might. Perhaps to its credit, the phone company has thus far treaded lightly. It has legitimate concerns about denying phone service to anyone based on how the phones are used. Unfortunately, that caution -- which many of Topeka's other institutions have shown -- is outdated. The Phelpses' willingness to stretch the bounds of reason has made it so. In addition, Bell clearly has an obligation to do everything possible to prevent abuse of its customers. The present situation calls for firm action. Palmer argues the phone company has the power to shut off phone service to the church under Kansas Corporation Commission regulations. Palmer also says the KCC regulations need to be beefed up -- to protect not just the recipient of the faxes, but the subject of them. Bell says it simply can't take the action Palmer is prescribing. Yet, it would seem otherwise. Regulations clearly allow the phone company to discontinue service that is used "for a call or calls, anonymous or otherwise, if made in a manner which reasonably could be expected to frighten, abuse, torment or harass another" Can there be any doubt that the above describes the Phelps family of faxes? It's time to stop pussyfooting around. If you feel Southwestern Bell should stop this madness, call the company and tell it to. Tell Bell to protect the law-abiding, peace-loving customers it enjoys in this area. And once Bell steps forward to end this tele-terrorism, the rest of the community should step forward with it. That means further action by the city government and law enforcement commun- ity to bring a resolution to the pickets, by the same family, that are intended to torment and disrupt Topeka's cultural and religious life. And it means other good citizens and corporate citizens stepping forward to defend one another -- to take back Topeka. The community puts it to you, Southwestern Bell. Are you the one to call on? ==================================================== Reprinted with permission of TCJ Editor Mike Ryan Phone Conversation, 01.21.95 From The {Topeka Capital-Journal} Letters to the Editor Sunday, January 29, 1995 Southwestern Bell Telephone has heard your calls, Topeka. But the message we've received is mixed. On one hand, we've heard from those of you who want us to unilaterally disconnect a customer's service for allegedly sending harassing facsimile messages. On the other hand are those who fear that such unilateral action by a telephone company could amount to an abuse of power. They support existing procedures, which involve safeguards for the suspension of any customer's service. They view these procedures as necessary to protect all customers from inappropriate limits on their speech. We understand and appreciate the concerns expressed by both sides of this troublesome issue. We hope the community appreciates our deliberate approach to considering the interests of all customers. We have heard complaints from customers claiming they have received harassing faxes. We stand ready to implement the established procedures to address their concerns. However, as a regulated telecommunications provider, we have a gen- eral obligation to serve everyone who requests service in our operating area. Therefore, before we suspend a customer's service we must have facts. At a minimum, the source of the offensive fax must be clearly established. The author of a fax might not be the person abusing the service of the complaining customer. For example, we need to make sure someone else hasn't received the fax, then retransmitted it to the complaining customer. To do that, we put a "trap" on the complaining customer's telephone line. But we can't do that without the written approval of the recipient. Once the sending customer has been identified we can advise him or her and law enforcement authorities that the faxes are not wanted by the recipient. We also will let the sender know that if they continue to send faxes to the complaining customer, their telephone service may be terminated. Although no customer complaining of unwanted faxes has yet to provide the necessary authorization, we are following up with customers who indicated a willingness to authorize a trap in response to {The Capital- Journal's January 22 editorial. In addition, we are investigating the December 19 court ruling by Judge Barbara that may establish grounds for enforcement action under our tariffs. If that's the case, it could ultimately lead to suspension of service. We are obtaining court records, and will carefully review those and take any appropriate action. We are also exploring procedures that could be implemented to deal with the problem of harassing faxes. There are various calling features, including Call Blocker, that may help. In short, Southwestern Bell Telephone is committed to taking what we think is a responsible approach -- one that meets our obligations to all of our customers. But we need their commitment, too. Without that, we are limited in our ability to solve their complaints. We are listening, Topeka -- to both sides of the story. Melanie S.

Marking a major milestone in the development of the information super- highway, the new network will be capable of combining voice, data and video transmissions together at 155 megabits (155 million bits of information) per second over MCI's high-speed backbone network, currently operating at 2.5 gigabits (2.5 billion bits) per second -- the equivalent of transmitting the entire U.S. Mail list of names and addresses across the country in less than a minute. "This network is the first-of-its-kind to combine both of these advanced telecommunications technologies in one seamless commercial operation nationwide," said John Gerdelman, president of networkMCI Services. "SONET and ATM will allow voice, data and video signals to be transmitted over the same channel simultaneously, and are vital components of the innovative multimedia applications and information services that we are developing." As communications technologies converge, MCI customers will continue to have available to them an increasing array of new services, from advanced telemedicine applications and rapid image transfers to remote data access and online shopping -- at the touch of a button. Last year, the company introduced networkMCI BUSINESS, the first software application combining important business tools, such as electronic mail, fax messaging, document sharing, videoconferencing and information services, in a single product. MCI also launched it's HyperStream ATM service, currently the Fastest on the market, and is the only carrier offering SMDS. This now gives MCI the lead in providing the nation's most complete data services. Other recent MCI innovations include internetMCI, a portfolio of services giving customers easy, high-speed access to the rapidly growing and increasingly popular Internet. MCI continues to invest in the latest telecommunications technologies, such as SONET and ATM, faster than other long distance carriers. Recently, the company added ATM capabilities and plans to provided SONET to its Developers Lab in Richardson, Texas, bringing the power and intelligence of these technologies to outside developers for the first time. The Lab, which MCI refers to as "the twenty-first century garage," offers developers the opportunity to test innovative applications in a live network environment. According to Gerdelman, MCI's goal is to create the "network for the information age," and provide not only access to information services, but content as well. "With SONET you gain certain benefits in terms of reliability and overall network performance," said Gerdelman. "ATM gives us the advanced switching capability for multiple signal transmissions. Combine the two and you have the foundation of a network that is well positioned to generate new revenue from these emerging markets." MCI plans to boost its transmission speed to 10 gigabits (10 billion bits) per second in early 1996, and is currently introducing new fiber optic technologies that will allow 40 gigabits (40 billion bits) per second transmissions in the near future. "If you think transmitting the entire U.S. Mail list in one minute is fast, just wait," said Gerdelman. "At 40 gigabits we'll be able to do it in only 4 seconds!" MCI, headquartered in Washington, D.C., has expanded from its core long distance business to become the world's third largest carrier of international calling and a premier provider of data communications over the vast Internet computer network. With annual revenue of over $13.3 billion, the company today provides a wide array of consumer and business long distance and local services, data and video communications, on-line information, electronic mail, network management services and communications software. networkMCI Services is the division responsible for developing MCI's information technology and operating its global intelligent network. ------------------------------ Date: Wed, 1 Feb 95 11:02:18 GMT From: ukcbajr@ukpmr.cs.philips.nl (John Bell 3313 ADV) Subject: POCSAG to be Upgraded to APOC To everyone interested in POCSAG, and new more advanced terrestrial paging systems for communications in tommorrow's world: An overview of APOC, the upgrade to POCSAG, is now available by EMail.

You can now request numbers from: 288 346 367 437 442 443 445 446 447 448 449 488 673 674 675 677 679 My favorite, 500.FOR.EVER, was already taken. Even though the install and vanity fees are waived during this sign-up period, if one requests a *change* (better vanity number) they will impose the $10 install and $25 vanity fees. AT&T claimed that as of yesterday (31-Jan-95) "All" LECs had agreed to provide access, so I should be able to use this from anywhere in continental US. (I'll be pleased if it gets worked out in three months.) A friend who has AT&T, but lives in an Alltel neighborhood says AT&T cannot provide her this service. Neither AT&T nor Alltel could explain. Yes, her AT&T calls *are* billed on the local phone bill. For the deluxe plans which offer sequencing, I'm told you can program the number of rings to try for each number. That's very important. My service will be turned on 15-Feb-95. John [TELECOM Digest Editor's Note: Like heck it will be turned on February 15! AT&T told me mine would be working January 21, then they said January 24. After that date passed, the due date was January 31 ... you guessed it; it still is not working as of today, Thursday, February 2 in the evening. I call them they say call Ameritech; I call Ameritech and am told to call AT&T. I call the Illinois Commerce Commission; they claim no knowledge of any 'agreement' reached between AT&T and the telcos. Now for the past couple days they won't return my calls. Supposedly my number is working if the caller knows to dial 1-800-CALL-ATT for starters, just like the cumbersome 700 service, but when I tried it that does not work either. I did not sign up for this service so my callers could hunt down a pay phone which allows 800 calls so they can punch in all those extra digits, even if that part of it did work, which it appears not to. Just now I called AT&T again about it; this time I got a woman who first said calls to 1-500 were not going through but 0-500 should be working 'just fine'. She put me on hold awhile and came back to report she had talked to 'the specialist' and was told 'everything was working fine' for Ameritech customers. Silly bunch of people! I told her to cancel my service and whenever they get their act together to give me a call back and I will think again if I need the service or not.

Cartwright Subject: Multiple ESN's per NAM (Update) I posted a few weeks ago about Cell One in MD (SID-00013) offering FlexPhone to their customers. To recap *it is* multiple ESN's per NAM. Up to three ESN's can have the same NAM. The cost is your regular service for one phone plus $18 for two NAMs, or plus $30 for three. The service _seems_ ;) to work as follows; The phones cannot call each other even if they are in different cells. Roaming is supposed to be disabled on all but the phone with the primary ESN. This is almost true, when I used the second ESN in roam every other call was blocked with a message that said you would have to use a credit card or third party billing to place a call. If I pressed send again (same number dialed) the call would go through. I'm not sure of this is a function of the cell system you are roaming in or if the information from your home system is getting confused. If calls are placed in the same cell at the same time by both phones one of the phones will get a fast busy. No calls can be made from the other phone while the first is in a call. CellONE says that calls can be made from seperate cells at the same time but reccomends against it since they aren't sure what will happen if both phones wander into the same cell at the same time (to be fair this came from a salesman since the tech folks seem to be hidden away fairly well). I haven't had a chance to check this one out but as soon as I figure out how to be in two places at once. I haven't seen a bill for this but I'm wondering if I should argue the fact since my secondary *can't* roam those calls shouldn't be billable. If anyone has questions I'd be happy to test things out if you can resonably describe your test case. E-mail is preferred and will get a faster response.

As for 'being two places at one time' you don't have to be. Wherever you are, just take both (all) of your cell phones and turn them on. Have them all sitting there then from a separate line dial the cellphone number. Now, you will have both phones in the same cell at one time obviously, and can test the results for your- self.

Some modems work okay with just a standard init string and a simple ATZ. I finally figured out one that works with 300bps - 14,400bps. Do a little tweaking and some experimenting.

On top of this, the standard V.42bis compression scheme can achieve up to 4:1 compression, so you could theoretically get up to 115k bits/second. I observe 2:1 to be more common, though, so expect about the same throughput as an uncompressed 56kbps leased line. > 2. What kinds of host supports 28.8K?

Your university's computer probably could handle it, but the modems they use limit you to 9.6 (standard V.32). This is a common situation. To test your modem, try some of the bulletin board systems in your area. Many of them upgrade more quickly than large university sites, because they have fewer modems to upgrade. Note that you can even try BBS's on which you do not have a login. All you need to see is that your modem will connect. >3. What is the speed of fax machines?

Let me get this straight ... you only use the modem to connect to the University computer system which only has 9600bps modems. Then why buy a 28.8Kbps modem if the other end can't do 28.8Kbps?? Even a 14.4Kbps modem would have been overkill. A 28.8Kbps modem will only connect at 28.8Kbps with another 28.8Kbps modem. Unless/until the University decides to upgrade their modems, you won't see any improvement. : 3. What is the speed of fax machines? Almost all real fax machines are 9600 bps. There are a few fax machines that support fax at 14.4. If you connect to another fax modem that also supports 14.4K then both faxmodems will negotiate a higher speed. Expect most of your faxes to go through at 9600 bps.

Greg's adjective "cryptically" is very apt. What the story does not make clear is that, under the ICC proposal, the combined 708/630 NPA area would go to *mandatory* 11-digit dialing in September 1996. This is because the 630 code would overlay the 708 geographic area for both landline and wireless service. The very real example is: You move to a new house and request service; your phone number is 630-NXX-XXXX while your neighbor's number is 708-NXX-XXXX. The city of Chicago is opposed because they believe this ruling will set a precedent for when the 312 NPA again runs low on numbers. By the way, this is not a done deal. The proposed plan is the recommendation of the ICC case worker. The full ICC will consider the recommendation in February. Given the noise being raised over mandatory 11-digit dialing, there may be some significant changes in the future. Mark Peacock Deloitte & Touche Management Consulting Detroit, Michigan [TELECOM Digest Editor's Note: Area 312 Chicago is quite unlikely to run low on numbers anytime soon.

The IN Services Delivery Platform is used today as the foundation for implementing a large variety of IN systems such as Service Control Points (SCPs), Intelligent Peripherals (IPs), Mobile Services Platforms providing HLR, VLR, AUC, EIR, and SMSC services plus gateways providing inter-standard connectivity services. The new UNIX version of Digital's IN Services Delivery Platform provides the same proven functionality as the OpenVMS version including: o NON-STOP AVAILABILITY: The IN Services Delivery Platform provides software fault tolerance plus the ability to implement configuration upgrades without service interuption. The platform has passed the strictest availability tests in the telecom industry performed by some of the most discriminating Network Operators in the world. o FULL RANGE OF CONFIGURATIONS: A unique client-server based distributed architecture allows a choice of configurations to match all levels of performance and availability requirements. The range is from an entry level platform (to be used in both a lab environment for development purposes or a live network environment for deployment of pilot or highly specialized services) through to fully distributed, high performance, high availability configurations. Applications running on an entry level platform are transparently upgradable to a distributed IN Services Delivery Platform. o POWERFUL PERFORMANCE AND SCALABILITY: Digital's IN Services Delivery Platform can handle from two to hundreds of SS7 links and thousands of SS7 messages per second. Non-stop addition and removal of machines to the distributed platform allows capacity to be added as requirements evolve. With the IN Services Delivery Platform's distributed architecture, Network Operators can be assured of the smoothest path available to grow the platform as the subscriber base and service success grow. o COMPLETE CONNECTIVITY: The IN Services Delivery Platform is fully SS7 standards compliant, including ITU-T, ANSI, and TTC. In addition, many country variants are supported. Different SS7 standards can be mixed on the same platform enabling the development of inter-standard services and gateways. There is a full array of physical connectivity options. For platforms deployed as Intelligent Peripherals, ISDN protocols and connectivity are supported including ISUP. o EFFICIENT SERVICE DEVELOPMENT: Applications can be developed in C or C++ languages using Digital's leading software development tools. The IN Services Delivery Platform has multiple Applications Programming Interfaces at TCAP, SCCP, and MTP levels which can be accessed simultaneously; a requirement for a number of new services such as GSM Short Message Service Center. o MANAGEMENT TAILORED FOR YOUR ENVIRONMENT: The IN Services Delivery Platform provides powerful and complete management functionality. The complete platform including applications, the configuration, and all of the SS7 defined Signalling Point functionality can be managed in a consistent way from a tailored management application using an object-oriented model. o WORLD-CLASS SERVICES AND MISSION CRITICAL SUPPORT: Digital has provided IN products and services to the major Telecom Network Operators in the world, including full round-the-clock telecom network mission critical support services for some of the highest service revenue producing SCPs in the world. Digital works with a variety of partners to deliver complete computing systems tailored to customer needs and is actively building an expanded global network of value added partners. Digital's goal is to deliver the highest performance and most cost-effective platforms for building computer based Intelligent Network solutions today. Digital's IN Portfolio enables Software Providers, Telecom Equipment Manufacturers, and Telecom Network Operators to produce and implement leading service revenue producing IN services for today and tomorrow's wireline and wireless networks.

In the Dallas-Fort Worth metropolitan area, you must dial 10 (not 11 digits) if you are dialing a call to a local number in the other area code. (Dallas is in the 214 NPA, Fort Worth in the 817 NPA.) One-plus dialing in those exchanges does not indicate that an area code follows, but that the call is a toll call. (Of course, now that an area code is required on all One-Plus dialing, there will be an area code on all toll calls, but at least in the Dallas-Fort Worth area the 1+ does not indicate anything but that the call is a toll call.) Note that almost all telephone service in the Dallas-Fort Worth area is flat rate. A local call generates no billing whatever (except for the very few message rate customers). This is true, I believe, almost everywhere in the United States except in the Northeast and in the Chicago area. The LECs would dearly love to introduce "usage sensitive pricing" everywhere, but customers with flat rate service generate such tremendous protest that even if the commission will consider it, the state legislature will start considering legislation to make mandatory message rate charging unlawful in that state. (The legislature would probably pass it, too, if the commission itself didn't reject the idea.) Complaining and protests about general rate case activity pale into insignificance compared to the heat generated by proposals to abandon flat rate pricing.

PAT] Chicago is a unique case though. Chicago will have an overlay area code, and since someone using a phone within Chicago could possibly have no idea what area code it is in, this means that all local calls must dial the area code and number, since phones right next to each other could be in different NPAs. In the rest of North America, we are having to dial the area code for all long distance calls within the area code, so that the system can handle the new area codes that look like prefixes.

Bell Canada chose to have it's Toronto customers dial ten digit LOCAL calls. This way, two exchanges can be used within a local calling area. Example: If you wanted to dial 1050 CHUM Newsroom in Toronto (416) from Pickering (905) (a local call) you would dial 416-923-1133. This would allow the creation of a 923 exchange in Pickering, which could be used for different customers. Inversely, to call someone local in (905), you would dial 10 digits 905-xxx-yyyy to call them from (416). This has already been implemented. The reason: Bell Canada is concerned that they will run out of exchanges in 416, and want to keep all 905 open for local calls. (Or else, 416 would have to omit certain exchanges that their local calls are made to ... it's so contrived ... and then when they run out again (which they will) they'll have to implement the ten digit dialing; let's get it all over with, they say). I believe that they now want universal dialing procedures across area codes for their customers, and subsequently are implementing this system across area codes that don't necessarily need it, like the 604-905 boundary. Always planning for the future, I guess. BTW, If you Americans want an example of a world class phone company, look north to Bell Canada. Great staff, instant repairs, easy access to all services (and tarrifs :-) ), quickly resolved billing disputes, hardly ever any billing errors, great business and residential service. >From the horror stories in the US, I think some companies could learn alot from Bell Canada.

You're making the increasingly unwarranted assumption that local bandwidth is expensive.

That's right, but they can make a bundle in doing so since they still get a per-minute charge on originating and terminating LD calls. (Some of my cousins run a small rural telco in Vermont that passes all of its LD traffic to NYNEX and AT&T. Because of their cost structure, they get an incredible amount for LD calls, something like 10 cents/minute.)

The current system is an evolution of an archaic and arbitrary system worked out between the phone companies (basically the old Bell System, when it was the telecom world) and regulators (FCC and State PUCs). The first step was to separate the costs, investments, rate base, etc., between the state and federal jurisdictions. The FCC then set interstate rates designed to recover the costs allocated to interstate servivce, and the state Public Utitlies Commission set rates to recover "intrastate costs". Interstate services originally were interstate toll. In the good old days, regulators and the phone companies kept local rates low by allocating the costs to toll. Growth in LD competition, bypass, etc., made this more and more difficult, and made it necessary to shift costs to local. Now, the FCC regulates the access charges LECs charge IXCs to originate and terminate interstate tolls calls. The FCC has also instituted a Subscriber line charge (SLC) to recover some of those "interstate costs" directly from the end users. This is the $3/month on your residential phone bill. Intrastate costs were recovered from local service and from intrastate toll. In the late 80's, intrastate access charges were added. These are charges to IXCs for originating or terminating intrastate (interLATA) toll calls. Because of the way that the costs are separated jurisdictionally, and given the subsequent wide discretion of the PUC in setting rates, intra- state and interstate access charges for a given LEC may vary greatly. For example, terminating a minute of switched traffic from IXC "A" to end user "Z" may cost the IXC 3 cents if the call is interstate and 8 cents if it is an intrastate call. Given a "revenue requirement" for intrastate services, the PUCs are faced with the dilemma of juggling rates between access and local, between residential and business, etc. Set access rates too high, the IXCs bypass the network. Set local too high, you don't get reelected or reappointed. While specific costs are a consideration, rate making is a highly charged political game. ------------------------------ From: pturner@netcom.com (Patton M Turner) Subject: Re: LD Termination Fees to RBOCs Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Thu, 02 Feb 1995 03:41:08 GMT edg@ocn.com (Ed Goldgehn) writes: > All fees charges for LD termination can normally be found in the > Feature Group tariffs.

I'm not condoning the actions of cellular phone time thieves, they are exactly that. However, the phone companies have been known to grossly inflate the value of things stolen from them (for example, placing the value of documents in the tens of thousands of dollars, when they could be ordered from the appropriate departments for less than $100). My question is that if they are truly losing hundreds of millions of dollars a year to fraud, why aren't they switching to known technologies (e.g., GSM based) which have per call authentication using a random number query with an encrypted key response, when such systems have been available for several years in other parts of the world? If they really are losing $300 million or more a year, it must be cheaper to replace every single cellular phone with a more secure system than to let these losses continue to escalate. If most of this amount is funny money, "lost profits" that they never really expected to generate, and use of excess capacity, then are the phone companies crying wolf? Are we currently in the position where the phone companies are like the suburban/rural household that never locks their doors "because crime never used to be a problem", and now screams for more police because they keep getting burglarized, but still never lock their doors? My main concern over cellular telephone fraud is that because it is partly due to decisions made by the phone companies, and that it's probably been exaggerated, that our government is either going to respond with excessive legislative and/or regulatory reaction to a technical problem, or with no action at all. Either way, it sends the wrong message.

There is also the problem that freephone numbers in Ireland are not in "area code" 800, they are dialed with the "special access code" 1800. That's 1800, *not* 1-800. The difference is that a hypothetical 800 area code would be dialed as (0800). Of course, Ireland won't ever put into service an area code 800; my point is that the 1800 access code is not treated the same as an area code. In the US, '800' is treated the same as an area code. In Ireland, 1800 is a special code like 153 for directory inquiries or 112 for emergencies. At any rate, that's what Telecom Eireann will tell you. (I'm not sure if 153 is the correct number or if 112 is in service yet.) My thoughts on the more general subject: (1) +800 XXX XXXX is too absurd to even contemplate. A seven-digit numberspace is far too small. Even eight digits is questionable. (2) With an eight- or nine-digit number, numbering spaces (not necessarily transparently related to the country code) could be reserved for existing subscribers. This seems a desirable option.

If this is truly an emergency situation requiring a page, then you'd probably be better off sending an alpha page. There is no standard or relatively reliable method of sending a numeric page by computer. At least using the alpha page entry protocol, you'll know you got the message *to* the paging system. Using DTMF to blind-dial a numeric page, relying only on delays to get the message into the terminal, won't give you any positive handshake.

TotalTel USA maintains their own network; they are not a reseller. On both inbound 800 and outbound direct dial service, TotalTel takes ANI info and translates it to CID, so if you call someone over TotalTel, even if your area is not CID-capable, your ANI info will be captured and translated and will show up on the callee's CID box.

In the early 1970's I lived near Moonstone, Ontario in Canada. At the time we got phone service from the Moonstone Telephone Company which was bought by Bell in 1972 I believe. Before Bell came in, our number was 33-W-21. The way it was explained to me was that 33 was our line number, i.e. the 33rd wire coming into the exchange. Each line had two sides to it, the J side and the W side (ADSL?) and our ring was 21, i.e. two longs and a short. I remember visting the switchboard with my mother, who was a friend of the night operator and the plugboard was wood, with large black plugs just like those seen in old photographs.

With the leading 1 before area code.

What 604/905 boundary? 604 is British Columbia. Did you mean 905/705 and/or 705/807? By the way, I wrote of the ten-digit scheme (see above) for some local calls originating in Maryland and going to other area codes. But other local calls from Maryland (to Pa., Del., W.Va. and to one exchange in eastern-shore Va.) still are just seven digits. The ten-digit scheme was implemented in the DC area to relieve a prefix shortage there, and replaced the seven-digit scheme; and you have that ten-digit scheme near Toronto for similar reason. mcardle@paccm.pitt.edu (Terrence McArdle) writes: > Just for clarification's sake, I assume the phrase "local numbers that > are in a different phone number" means dialing a destination existing > in separate exchange, but the same area code, as the originator? > Calls that cross a LATA boundary currently require eleven digit > dialing, do they not? I think you meant "local number in a different area code". LATA boundaries don't always follow area code boundaries. I think 609 in New Jersey is split between two LATAS, with long distance within 609 being just seven digits. ------------------------------ From: TELECOM Digest Editor Subject: Reminder: Send in Those Biographical Sketches Date: Fri, 3 Feb 1995 08:30:00 CST This is just a reminder to all that the Telecom Archives now has a section called 'profiles' where reader/participants who have chosen to do so have a short biographical sketch of themselves on file for other *participating* readers to see. The way it works is this: You send the two or three paragraph sketch of yourself to 'ptownson@eecs.nwu.edu'. This can be something like who you are, your educational and professional background, your age and personal interests, etc. It gets installed in the profiles section of the Archives and you in turn get the needed password to access that directory and read about the other telecom people who have submitted the same. The profiles directory is *NOT* accessible using FTP or other services. It can *only* be accessed using the Telecom Archives Email Information Service, and then only by supplying the correct password within the text of your email. In return, you get the desired profiles of other participants sent back to you by the email server. This is designed to protect the privacy of all who wish to participate. You must provide data about yourself in order to read the data of others. This is intended as a 'human resources' sort of thing; a way for people in the telecommunications industry to get in touch with others with desired job-related skills. It is also intended for Digest readers to get aquainted with others who write in the Digest from day to day. I install these profiles as quickly as possible when they are received and by return mail you get a reply from me when your profile is in place along with instructions on how to access the other profiles.

Last April, we moved from St. Charles, Missouri to Hillsboro, Missouri. Not far, only 65 miles. I had contacted SouthWestern Bell to get a new number, a local number. No problem. Our long distance carrier for the previous three years was Telcom*USA. I had explained that I wanted this to remain as it was. In Hillsboro, we got our first bill. Along with a bill from MCI for long distance calls. We had NEVER contracted with MCI. Our LD company was bought by MCI, but bills us separately. First I called SouthWestern Bell, then MCI, then SWB, ... Turns out the previous "owner" of the phone number had used MCI, but had neglected to stop the service when she moved. Six months and 30 phone calls later, I contacted the PSC. With that kind of help, it appeared to be straightened out ... until last month. With the SWB bill came another MCI bill -- in a chopped-up version of my wife's name (the original name we had the old number under!). I called MCI. "No problem, we'll fix it right away." I did tell them that if I got another bill from them, I'd call the PSC and, probably, the State's Consumer Affairs Division for an in-depth investigation. Which I will. Eight months of listening to two companies declare "It's not my fault. Call the company." What happened? 1) Southwestern Bell dropped the ball in not closing the previous user's accounts when the number was closed. They did not inform the LD carrier. 2) Southwestern Bell didn't check the billing statement to notice TWO different names on the statement. 3) MCI missed the boat. When I called, they seemed to think nothing of the fact that the long-distance service was not in my name. 4) Telecom*USA, when informed of the whole proceedings, declared that I had a "$5 minimum usage" charge on my acount. When in reality, I didn't. 5) Southwestern Bell AND MCI don't compare notes when user's start complaining about mis-billing. Only when state agencies get in the act, do they begin to resolve the problem. Is it over? I don't believe it will end until the PSC gets involved again. This is a time that makes me wish there were two local companies. That way the competition would force them to be as caring of their users as they are about their money. On the other hand, I believe that Murphy was an optimist. Michael W. Jenkins Computing Support Services Dept of Internal Medicine Washington Univ.

It always starts with our neighbours in Toronto :-) Seriously though, I see the same sort of thing happening in Ottawa-Hull shortly. For example, I know that there are Ottawa 613-56x-xxxx and Hull 819-56x-xxxx which are local calls from each other (a favourite is a friend of mine who lives at 819-561-xxxx and works at 613-564-xxxx). I don't think it will be very long before the Ottawa side would like to take 613-561, and then we'll be forced in to ten digit dialing. > Always planning for the future, I guess.

Besides the fact that they are hopeless for doing anything out-of- the-ordinary (ie: try calling them up and ask to talk to someone about ISDN or T1 service...), Bell Canada is a pretty good company. I am not rushing out to any of the new long-distance phone companies because Bell does the job for me. Now, if they would only increase my local calling area. And while we're talking about ten vs. eleven digit dialing, I like the '1' in front of long-distance calls just to denote that I understand that I will be paying for the call. No '1' would symbolize a local phone call, even if it required an area code.

Several issues are being raised here so let me try to sort them out. For FGD, many tariffs if you break them down, have a 1/3 the cost in switching, paying for COs and access tandems, 1/3 in transport, the bandwidth, and 1/3 in Common Carrier Line on the originating or terminating end, what the carrier pays to support (subsidize) the line to your home or business. This breakdown is approximate and varies from LEC to LEC, but it gives you the overall picture. Only about a third of the charge is for bandwidth as most of us would interpret the word. The other element is switching. Switching and the lines to the customer premises are really what is expensive. The lines are not heavily utilized, in the case of many small businesses and residences. Switches are expensive and are not set up to support multiple hour calls. Regular business calls that get through are typically 4 to 6 minutes in length with residential calls longer since many are placed to friends and family. Switches were engineered on the assumption that most calls would be short. As data usage increases, the switches have to get bigger, an expensive proposition or the multiple hour data calls will have to shifted to another technology, such as packet or cell switching where switches and long distance circuits are not tied up during think time. Most modern CO switches detect a phone that is off the hook and not transmitting and genrate an obnoxious tone to get you to hang up.

It would be nice if it also had a keyboard, screen, and maybe a mouse so it could have a neat interface. This is called a computer (sarcasm). Your box will probably consist of another PC (maybe an old, abandoned 286 ...) with a FAX modem in it, with some sort of networking hard/software so you can access its hard drive from your PC. It sure would be a lot simpler to leave your PC on; cheaper, too. Is there a reason you can't do this? With the monitor off, it consumes very little power.

Small world department! I can remember standing in the Moonstone Telephone Company office, waiting to make a call to a friend who lived about a ten minute drive away, but was served from the Bell office at Port McNichol. This was 1970 or 1971, and the wait was for an 'outside line'. There were no payphones in Moonstone but since the office was right there in the centre of town, you just went in and asked the operator for your call and paid in cash. At the time, my friend's farm had been served by Bell (on a 4 party line) for only a couple of years. The old open wire on poles was still visible by the roadsides, collapsed in places. My friend still has the surprisingly modern crank phone that Bell left in his house when they installed the new line and standard 500 set. Moonstone was one of the last batch of Bell acquisitions of small rural telcos in the province. Now there are still a few 'ma & pa' telcos in Ontario, but they generally have all digital COs (DMS10s, typically), and are not interested in selling out.

I decided to try this in our lab, and he's right! Standalone Caller ID boxes that display calling number, or calling number and name, "listen" all the time, and any time a valid incoming Caller ID comes in, they display it! I checked several brands, and they all behaved this way. Someone should alert the telcos and police, so innocent people won't be accused of prank calls. I can already think of several evil plots that could be made in movies of the week. However, I also had a couple high-end telephones handy which included the Caller ID feature, and they wouldn't accept a new Caller ID after going off-hook. The reason for this is both phones are ADSI Level 3, and they comply with the exhaustive Bellcore requirements. An ADSI Level 2 or Level 3 telephone that accepted Caller ID after going off-hook would fail some Bellcore tests. Unfortunately, an ADSI Level 1 or Level 2 device that wasn't a true telephone, e.g., a standalone Caller ID box, could still be fooled by an off-hook Caller ID burst, and the design would pass the Bellcore requirements. In case you're been muttering, "What the heck is ASDI," I'll give a brief explanation. The acronym stands for Analog Display Services Interface, and it is a new type of telephone designed to work on a standard, analog telephone line. (POTS line, Plain Old Telephone Service) There are three "levels" of ADSI: Level 1: Calling name and number after the first ring. Level 2: Calling name and number with call waiting. Level 3: A telephone with a display screen. (The "D" in ADSI.) ADSI Level 3 came about because Bellcore did a study to determine how to sell more features on a telephone line, such as call waiting, or call forwarding. (The RBOCs like to sell these extra features as they are revenue above the standard line charge, and quite profitable.) The study concluded that many people didn't buy extra features because they didn't want to fool with code sequences to enable/disable features, such as *69. Bellcore's solution was ADSI. A Level 3 device has a screen that must be 20 characters across by 6 rows, and can be 40 characters across by more rows. There are from four to six "softkeys." Menu trees of softkeys can be downloaded to an ADSI phone, and stored in memory as a "script." The user gets plain English displays (or the language of your choice), and can press softkeys to activate telco features, or even order new ones directly from the phone! The REAL attraction of ADSI is that ANYONE can have their own ADSI server! After all, it's designed to work on analog lines. In a couple of years, a screen phone will be used to call the local video store, scroll through the new releases, and even reserve one for later pickup. Or, perhaps one could call Domino's, order a pizza and toppings. Just imagine calling a business, and instead of getting the tedious voice mail prompts telling you to press *1 to do something, you get a text screen that lets you scroll though a directory of employees and select who you want! The high end ADSI phones that I have tested even have things like pull-out QWERTY keyboards for data entry, PCMCIA Type I slots, "smart card" slots, and magnetic strip card readers! Bellcore deserves praise for this well thought out service, laid out in several Bellcore standards. Another smart move on their part is that they didn't bother submitting the standard to an international standards body to try to get it adopted. (We all know how long that takes.) Instead, they have been visiting the PTTs of dozens of countries, and trying to convince them to sign on to the ADSI standard as defined by Bellcore. Several European nations have expressed interest already, as have Pacific Rim nations, including China. ADSI is being field-trialed by a few RBOCS right now, including Ameritech in Chicago. Ameritech is selling high-end Phillips ADSI screen phones at cost for only $200 each, and primarily marketing it for enhanced banking features from your home, along with the ability to easily order/change custom calling features. It is estimated that there will be between 5 and 15 million ADSI Level 3 screen phones in North America by 1998, and I suspect the higher number is more accurate. Once you've tried one, you don't want to give it up! It is my opinion that ADSI, along with V.34 modems giving true 115 kbps data throughput (via compression), could be an ISDN BRI "killer" one-two punch. ISDN is STILL not ubiquitous, the local telcos don't understand it and don't sell or market it effectively, and it will NEVER be offered in the boondocks where I live. (Mayo, Kentucky) In closing, perhaps the Editor will permit a small plug for my employer. TestMark Labs is currently the ONLY alternative to Bellcore itself, if you want your ADSI product tested for compliance to the full Bellcore requirements. By the way, even though ADSI works on POTS lines, it qualifies as PANS. (Pretty Amazing New Stuff.) John Combs, Project Engineer, TestMark Laboratories, testmark@mcimail.com [TELECOM Digest Editor's Note: The thing to remember with Caller-ID is to look at the display *before* you answer, not afterward! Or if you do go back and review it afterward, do so in a discerning and sophisticated way. Bogus information sent down the line while you are in the process of going off hook and getting the phone to your ear probably won't look quite the same. For example, the time will probably not be shown, since telco usually sends this. I've never seen a CID box with its own clock. Even if there is a time sent with the bogus information, look to see if it is the same time as the real one. It would be highly unlikely you had two calls in the same 'minute'. Look to see if the one right before the one currently displayed says 'private' ... at the same minute in time yet! Keep your eye on the CID display as you take your phone off hook and bring it to your ear. Notice it suddenly change? It is hard to explain how or why, but after you have had CID for awhile its like when you are on the phone all day. You *know* what you are supposed to hear next in terms of ringing tones, etc. You'll get with CID to where you *know* what you are supposed to be seeing. Something different pops up and if you have sort of trained your eye to notice things, you *will* see that something does not look right; you will flip through the entries in the memory and sort it out. Even if the prankster has the sense to send the time stamp along, unless he has his clock synchronized with *your* central office's clock (your office supplies the time, not his) then his bogus entry may have a time one or two minutes *before* the real one. You would not have an entry in the display which came afterward but with a time prior to the one before it, and if you do, that's a giveaway. After a few calls with CID, you learn what to expect there and how, etc. PAT] ------------------------------ From: Berton Corson Subject: Sprintnet Question Date: Fri, 3 Feb 95 18:29:45 PST Patrick: Got a question. I'm drawing a blank here. In using Sprintnet, one types a 'C' followed by a destination to connect to another system. I forgot the destination I use to look up Sprintnet local phone numbers. I remember both passwords were 'PHONES' but the destination escapes me. Do you know??? Bert [TELECOM Digest Editor's Note: It seems to me the mystery word is 'MAIL'. I think you do 'C MAIL' then the password 'PHONES'. At one time I wrote an article for the net entitled 'Let Your Fingers do the Walking'. It was a long, detailed account of all the interesting connections you could get (at that time) depending on what you entered after the 'C'. I listed quite a few test numbers, loop-arounds, manual terminals with operators you could interactively chat with, etc. I listed in one part of my article novelty connections you could make to things like the British Telecom Master Clock, a master clock in Japan operated by whoever Telenet (the old name for Sprintnet) gatewayed with over there, etc. I included a bunch of addresses which connected to outdials of Canada Datapak. I mentioned some addresses which gatewayed into the old Western Union telex system and similar. Telenet saw the article and stunk up the place something awful. They took particular umbrage to the fact that I mentioned that the old PC Pursuit accounts were not blocked out from reaching those international destinations. I also mentioned the numeric addresses for the indials themselves, and told cryptically how 'some hackers' would call into thier local Telenet indial, do 'C address.of.same.indial.in.rotary.hunt.group' and then sit there on the line *and provide a bogus Telenet prompt* to some unfortunate sucker who also dialed in, thus capturing the password of some unsuspecting user. In other words, let us say there are ten lines in a rotary hunt incoming to Telenet (Sprintnet) via ummm ... let's say Chicago-Merrimac office, or Chicago-Irving office. You call in on line one; do 'C address.of.these.outdials'. Since line one is occupied naturally -- by you -- your C request would hunt to line two and there you would sit. Now comes another inbound call and the telco CO parks him on line two, staring you right in the face looking at him. You see him give those carriage returns to get Telenet's attention, and *you* answer him asking for his password. Like a dummy, he types it right in. You say 'sorry, network problems, please disconnect and dial back again.' He hangs up, you hang up and split. Now you have a password. I kid you not. More PC Pursuit passwords and Telenet network passwords were stolen by that gimmick than any other scheme. Telenet finally wised up and put their incoming lines in one hunt group and their outgoing lines (outdials) in another group with a network restriction so users could not connect to the incoming lines. If you try doing 'C a.dialin.somewhere' now the network responds saying the address you have entered is not in service for incoming connections (from persons already on the network). I promised them I would not again publish 'Let Your Fingers do the Walking' so that's the way it has to be. Anyway, try 'C MAIL' with user name PHONES and password PHONES.

A friend of mine and her mother are Marketing Reps for Excel LD phone service. They say that they can save me a significant amount of money over AT&T, my current LD carrier. Their examples are the differences in charges for one-minute phone calls. EXCEL has lower flat rates, while AT&T charges more for the first minute, but they virtually are identical for longer calls (avg. time: 10 minutes). EXCEL also charges a $3.00 flat fee for their service. Of course, since this is a MLM operation, my friend and her mother will be collecting commissions on my phone bill. So it seems that what I'm really being asked to do is switch over to a service that is no better (and hopefully no worse) than the one I'm using now, that may or may not save me money, but will shift some of the money that used to go to Southern Bell and AT&T over to my friend and her mother. Not that I have anything against doing that, but does anyone without a financial stake in EXCEL have any real-life experiences with this service? Is their any real savings over AT&T?

They are in New York City. Every allocated channel is occupied, though in a very inefficient manner. While it may be possible to free up at least one wide-band channel by forcing at least one of the larger FM stations to stop hogging more channels than they really should ;), the cost to accomplish it, and of real estate for microwave antennas, and for equipment expense, would make it difficult for even the largest broadcasters in the country.

Apparently it was for a short time reduced to seventeen years, now there is no restriction at all. Also I was corrected on the year of their founding: it was 1911. In that year, several of the employees of AT&T who had -- even then! -- been with the company for twenty years or more -- a few had worked with Thomas Watson himself -- decided to form a service organization. Their first projects as an organization were with deaf people, and to this day hearing impaired people receive much of their time and resources. Alex Bell was deaf, you know, and a teacher of deaf people. Have a nice weekend everyone! Very cold and snowy here, and the cold will linger until Monday at least we are told.

None of them are really good at telling you how. Here, then, is the first "all-in-one" compilation of Internet server tools. The book covers everything from simple finger responses, to mail servers, to ftp, to WAIS, to Gopher and World Wide Web servers. "Firewall" security, legal issues and intellectual property are touched on. While technical details predominate, there are practical suggestions for design as well. Unfortunately, this book is not really for managers. The material is demanding and requires a knowledge of UNIX. The authors note this in the preface, and it is fair to say that Internet server management is a technical task. At the same time, it would have been possible to have started with simpler items and more basic explanations. As it stands, the book is more appropriate for either the technical staff in a large company or those involved with setting up a UNIX Internet access provider. Perhaps a companion volume aimed at the more general user would be a future project. copyright Robert M. Slade, 1994 BKMININS.RVW.

PAT] Mr. Brown, I have the same publicly-available information that you have. But I do have a few questions. Rather than private email, I would prefer to maintain the public forum of the TELECOM Digest so that this thread remains available to all interested parties. AT&T can no longer publicly maintain that their users don't care about their 800 numbers. In January 1993, the United States developed a position that included grandfathering of existing U.S. 800 assignments. This was further endorsed in October, 1994, by the U.S. Users Statement, which also rejects the lottery. And why shouldn't they? U.S. carriers have aggressively encouraged U.S. companies to invest in and brand their 800 numbers, leading the way themselves with such visible and successful marketing campaigns as 800 PICK ATT and 800 COLLECT. Indeed, 800 COLLECT is a trademarked brand. The overt lack of carrier support for customers suggests that the substantial investments of money and brand awareness in 800 PRODIGY, 800 JEEP EAGLE, 800 MERRILL, and others, are not important to their users. Or, that those users are not important to their telecom vendors: the carriers. Is 800 COLLECT also to be up for grabs? (Where do I sign up? ) When presented with this question, a participating MCI representative retorted that 800 COLLECT was useless overseas because there are no letters on the phone pads. We all now know that a new international telephone pad standard has been adopted. That argument, like the others, holds no water. So why maintain the propoganda that it doesn't matter? That your customers are willing to lose the very competitive edge that you yourself have helped them attain. Given the opportunity, wouldn't the carriers rather gain entry into European markets *and* protect and promote the interests of customers at home? U.S. users have spoken. They care. They stand to lose a great deal, and gain nothing. So how do *you* suggest that we move forward in a fair and practical manner to address everyone's interests?

Aeronautical Radio, Inc. (ARINC) is the technical representative of the airline industry, acting on behalf of the US airlines who have a big investment in 800 numbers for their reservation systems. This organization, via its ITU participation, has been working hard on behalf of all U.S. 800 number users (for example, they gathered the impressive ranks of such users as American Express, EDS and the Ford Motor Company to draft and present the "Users' Statement of Principles Regarding Universal International Freephone Service.) Their stated mission in this matter is to protect and promote the interests of all U.S. 800 number users. The contact person at ARINC is Ben Levitan, 410 266-4111.

In fact, a whole new programming model called intensional programming has begun with applications in a wide range of areas including parallel programming, dataflow computation, temporal reasoning, scientific computation, real-time programming, temporal databases, spreadsheets, attribute grammars, and hardware synthesis. This symposium aims at bringing together researchers working in all aspects of this area, and to promote intensive discussions and foster collaboration among researchers. We encourage papers dealing with the theoretical foundations, design, implementation and prototype development issues, comparative studies, and applications, as well as those describing new challenges arising out of applications. The symposium will include, but will not be limited to, the following topics of interest (as they relate to intensional programming): Programming paradigms Semantics * dataflow computation * non-determinism * connectionist models * extended Kahn principle * logic programming * intensional concepts * real-time programming * termination issues * visual languages * languages such as Lucid and GLU Software Engineering Applications * version control * signal processing * visual user interfaces * image processing * parallel programming * hardware synthesis * fault-tolerant systems * graphics * program verification * data models Submissions You are invited to submit either a full paper or an extended abstract of approximately 5000 words (10-15 double spaced pages). The cover page should include the name, phone/fax numbers and e-mail addres of the contact author(s), a short abstract, topic(s) and a list of keywords. Papers will be reviewed by the program committee for their originality, correctness, significance, and relevance to the symposium.

Um -- how does this differ from inumerable similar failed projects like the Northern Telecom DisplayPhone or Bell Canada's Alex terminals now languishing in the remainder bins? The experience with Minitel in France is that sure -- everyone wants one *as long as they don't have to pay for it*. Start charging market rates, and the units are returned as fast as you can get a dial tone. Massive state subsidies is just not in the cards in North America, at least.

Including international calls, UK 31c/min) and got on the phone to talk with Sprint customer service. I asked if they would match the offer (I have several lines and am a good customer of long standing) ... bottom line is they would not match, nor do they have a tariff that's similar ... BUT they offered me a so-called "concession credit" on my account of $50.00 for my loyalty. May I recommend this to TELECOM Digest readers who are current Sprint customers? It's a dog-eat-dog world for customer retention out there and we the customers should benefit from it whenever possible.

No offense to MCI, but that sort of reminds me of an old Firestone ad: "Firestone Tires stop 40% faster" Of course, they fail to mention what they stop 40% faster than. So, if they mean 50% of the AT&T price for a similar call, that is one thing, but if it is just 50% off of their imaginary rates, I would do a bit more homework ... Daniel J.

I received the same type of marketing call from MCI, and the salesman said that MCI would match any plan that I already had, including an AT&T Reach Out America calling plan with no calling card surcharge on the weekends that is no longer offered to new customers.

Date: Sun, 05 Feb 1995 23:50:00 CST So after going outside early Sunday morning in very bitter (one degree above zero) weather to steal my neighbor's copy of the {Chicago Sunday Tribune} before he woke up and saw me out there, I immediatly turned to the section of the paper I never miss. No, not the front section news. Not Perspective, or the editorial pages or the Sunday Magazine. I ripped the six pound, five hundred page paper apart looking through all the innards, the Marshall Field advertising, the grocery coupons and such looking for the Sunday color comics so I could go sit in my kitchen in a stupor with a cup of coffee and see what Mary Worth, Blondie and Dagwood, Beatle Bailey, Brenda Starr and the others had going this week. A new serial began with Dick Tracy this Sunday, and you will surely all want to follow it. It seems a hacker has broken into computers all over town and is wreaking havoc. A cash machine spits out thousands of dollars to a man who requested twenty dollars. Computers in companies display pictures of Santa Claus in a 'wanted poster'. The telephone exchange is okay so far, but the story line hints it will soon be disrupted. No doubt over the next few weeks Dick Tracy, his partner Sam and that lady detective will catch the miscreant hackerphreak responsible for all this mischief and bring him to justice, comic page style. Does someone want to summarize it here each day for the duration for the benefit of people who don't get Dick Tracy in their paper? I get the {Chicago Tribune} most days -- by the way, 'Dick Tracy' belongs to the {Tribune} you know, or did you know? -- but they send him out across the nation daily via the syndicate. Anyway, I am sure it should be a very amusing and interesting little story over the next month or so, three picture frames daily and nine on Sunday with bubble messages in each. If someone wants to save me the trouble, let me know.

Martin, to prove the clock slip problem once and for all you should schedule an end to end test on the digital level. If you go through your equipment the LEC will assume it is your equipment, which it very well might be. I am assuming the trunk is a T-1, if so you can easily check for clock slips by stepping out the testing through the network using a Fireberd or similar test set. If you believe the clock slips are in the LEC's internal network then attack it as a quality issue that they must resolve. In case of the latter your most difficult task is to quantify the problem and here's the biggie, demonstrate it. If it is a clock slip it should be fairly regular and predictable.

It seems to me that using the phase shifts of a modem carrier would be rather indirect. It could be difficult to tell the difference between a clock slip and a modem retrain caused by some other factor. It would be easier to just hook up a point to point BERT test. You should see frame slips as _periodic_ bursts of bit errors on the BERT testers. The time period between bursts of errors will depend on the rate of change between the two different clock frequencies. The off campus BERT tester isn't necessary if you use full-duplex modems that support remote loopbacks.

Your trunks are probably running on several different T-carriers on their way to the CO. There are definitely dozens of T-carriers in your local area. You're probably only having problems with one or two segment out there in Telco-land. Try to find a commonalty that can help the local techs locate the bad segments. Look for one group of trunks that have the problem, or one area of town, or it's only when a call goes outside the local calling area. The more accurately you can describe the problem the better chance you have of getting it fixed.

I work in an office with five IBM mainframes tied together as one virtual machine, 7,000 PS/2s connected via a flat token ring, 13,000 data terminals, two central office switches that are used as PBXs, and 13,000 phones. Every day that I come in, I have to personally reset the file server on the LAN because I can logon only about 50 percent of the time. But, I can always pick up the phone and make a call without having to do an IPL on the switches. I would never trust LANs to carry voice any time in the near future. PCs and LANs are not engineered to the same standards for reliability and backup as PBXs and other switches. If you ever get into a management position, the first thing that will give you headaches is the number of times that mainframe applications go down during the day, the numbers of LAN servers that go on the fritz, and the number of folks complaining about something wrong with their PCs. But, not the phone system which is rock solid and reliable. We have ISDN on our switches which makes them extremely reliable for data communications, server access, connecting to the Internet, and information databases outside the building. I wouldn't want our PBX to go away because it is a powerful data switching machine that is always up when I need it.

Computer Science and Eng., Beaverton Certainly anyone who predicts that PC's can't do a task will eventually be proven wrong, but I believe it will be quite a while before large PBX's or high reliability PBX's will be replaced by PC's. I have managed a 3000 line NEC PBX for five years now, and during that period, it has never experienced a system failure. On the other hand, it is rare that our PC's run for more than a week w/o CTRL-ALT-DELETE needing to be invoked. In a large user environment, perferction is the expectation, and Microsoft has never demonstrated that capability. For instance, when you have direct integrated T1's, any little glitch will dump any modem call on the system -- just one bit! Our PBX is fully processor redundant, and switches daily between processors without affecting phone traffic. It also has an architecture that supports expansion up to 20,000 stations. I suppose a network of PC's could eventually do this too, but you can imagine it is non-trivial. It does appear that some PBX manufacturers are moving in the PC direction. NEC has announced the 2000IVS, which is an Intel processor based PBX, and has ethernet capabilities. Apparently, it is becoming the darling of the CTI crowd. Also, it is very low cost, about 1/2 per port of our NEC, and has all the same features plus more. I feel much more comfortable seeing CTI from PBX vendors, rather than PC/PC Software vendors. Maybe the threat of competition and loss of market share will spur on the PBX people. Franky, the cost of many PBX features is outrageous, and the CTI has been very slow to come. ------------------------------ From: edg@ocn.com (Ed Goldgehn) Subject: Re: LD Termination Fees to RBOCs Date: 5 Feb 1995 19:04:17 GMT Organization: The INTERNET Connection, LLC In article , pturner@netcom.com says: >> BTW, the method of charges is entirely different for LD service in the >> cellular industry.

The cellular industry needed to attract long distance carriers to make connections to their networks in order to sell their services. It didn't do much good to provide local cellphone service without LD capability. But, the LD carriers weren't going to make those connections on the same basis that they make their existing LD access (by the connection and by time). So, since the cellular industry needs the LD capability to sell its local calling service, the fee structure was virtually eliminated. I don't know which cellular carrier was first to do this (I would take a guess that it was McCaw, but don't quote me on that). But, from what I've heard, this practice is now widespread.

Date: Mon, 6 Feb 1995 01:16:12 EST After hearing about NYNEX/NY's (Boston too?) "Free Weekend Airtime", which allows toll and airtime free calling to anywhere in 212, 718, 917, most (all?) of 201, most (all?) of 908, (609 too?), and most parts of lower 914, I broke down and had a friend of mine who was going to cancel with Metro Mobile in CT sign up with NYNEX/NY rather than Cellular One. Due to NYNEX/NY's totally un-professional and erratic call-delivery system, as well as its significantly poorer coverage in most parts of NY (in NJ it is slightly better), and higher roaming rates, I normally do not even suggest NYNEX when someone asks me about service in NYC. (Although CO/NY does bill for incomplete calls over 40 seconds, so in some rare cases I will suggest that a person use NYNEX instead of CO if they make a lot of calls where the party they are calling takes over 40 seconds to answer.) However, free weekend airtime is something that's hard to argue with, so I told the guy to go with NYNEX, and he is in general happy with them for the free airtime (Until June?, enough so that he is willing to put up with their inferior coverage (signals rarely penetrate buildings, CO's signals seem substantially stronger inside buildings on average). However, they insisted that he have a fraud protection PIN code on his phone, as has been discussed here in the Digest in previous issues. This raises a question: Normally, for any call which is answered, billing STARTS shortly after you press SEND, when the system recognizes/validates your phone and processes your outward call. Thus, if you dial a number, and it rings for four minutes, and on the fifth minute it is answered, you will pay airtime (and perhaps - incorrectly - toll charges) for the FULL 5 MINUTES. Now how does the PIN code fraud feature affect this? I've timed how long it takes to get the "prompt" to enter your PIN code, and then to enter the code while driving, and it is about ten seconds. Now do these tenseconds count? Thus, if you place a call and are required to use the PIN, if the call lasts 65 seconds total, from the time you first sent out the call, are you required to pay for two minutes, or does the switch only start the airtime counter from when it receives a correct PIN code? Anyone test this? I'm interested in finding out because if I find that NYNEX/NY is billing people from the time they *initially* hit SEND to place the call rather than when a caller enters his/her complete PIN, I will call NYNEX/NY and demand to have the PIN feature removed.

Some contributors have made the point that in "stealing" someone's goods or services, you steal their profits as well. Others maintain that only the replacement cost should be considered, if that. This question of real versus phony losses reminds me of the old joke: It seems there was this well-to-do lady walking down the street, back during the Depression. When she gets to the corner she sees a shabbily dressed fellow, obviously down on his luck, selling apples. She figures she'll help the poor guy out. "You there, my good man, I'll take an apple. How much are they?" "One million apiece," answers says the apple vendor. "Are you mad?" says the lady. "A million dollars? Don't you know you aren't going to sell very many apples at a million dollars each? What sort of fool are you?" "Who's the fool?" says the vendor. "I only need to sell one!" Sure, sure, bad joke; but stick with the premise for a moment: Suppose instead, at the end of the story, that the lady hits the guy over the head and steals his whole tray -- an even dozen apples. How much loss does he report to the police? How much loss has he suffered? If they catch the woman, what crime do they charge her with, grand larceny or petty theft? Does the fact that the vendor *priced* the apples at a million bucks each make them *worth* a million each? And what do the headlines read the next day? "Rich woman mugs beggar for twelve cents worth of fruit." -or- "$12,000,000.00 apple heist called `Crime of the Century.'" Gary Novosielski GPN Consulting [TELECOM Digest Editor's Note: The product is worth whatever the seller says it is worth, period. Its his product to be defined however he wishes. Whether or not anyone else agrees with his assessment is another matter. Generally we buy things we don't need based on our belief they are worth more than the seller is asking, not worth less than he is asking. If he says the apple is worth a million dollars, then that is what it is worth. If the cellular carrier says a fraud call was woth $X, then that is what is is worth. Now: how seriously would such claims be taken? In other words, what would the headline be the next day? Well, since he is an old dirty bum, his word on the subject would mean nothing. On the other hand, since the telcos and the computer gurus all speak their own language that no one else understands and since they dress properly and act as though they know what they are talking about, their word means everything. Everyone 'knows' that apples are not worth a million dollars, and the same people who 'know' this also are the kind to take everything telco says at face value. (The Telephone Company once said blah blah, fill in the blank). Therefore what telco says is true and old bums tell lies. Of course it also helps if you have an attorney who is good at sucking up to the right people, and a public relations department trained to bark on command. Don't you understand anything? Truth is whatever the right people say it is; the people who are in the proper circles, who dress and act properly and who say things the right way.

The other element is switching. That happens to be the way Feature Group trunks are priced. Of course the whole trick to FG pricing is that it's intended to be "contributory" (profitable). This comes from the old separations game of "splifs", for "subscriber plant factor" (SPF). In that game, the average usage of LOCAL lines is divided into interstate and intrastate baskets. The interstate portion is MULTIPLIED by SPF and then the total cost is divided amongst the two jurisictions. Given SPF of 3 (old ballpark; I don't know what it is now), then if 15% of calls in a jurisdiction were interstate, then the cost would be divided 85:45 to local/interstate. The subsidy, folks, is in the splifs. Interstate cost is currently divided into the part paid via tolls and the part paid via CALC ($3-6/mo "access charges"). The toll-usage part is divided into different components and adds up to 3-5c/minute/ side-of-call for most telcos. > Switching and the lines to the customer premises are really what is > expensive.

At least in part because the FCC *requires* all cellular carriers to provide AMPS-standard, unencrypted, analog service. They are free to offer alternatives as well, such as CDMA and TDMA (GSM, too, if anyone cared to do so), but they still have to provide service to unencrypted analog customers. Also, phones using the unencrypted AMPS standard are cheaper and provide better voice quality than the alternatives; the companies' customers have analog phones. Cutting off the majority of your customers to prevent fraud is a great way to go out of business. The cellular manufacturers have been working on new standards for nearly ten years. They aren't about to come up with yet another standard -- analog with encryption -- that will be incompatible with every system out there, and the carriers aren't about to buy it when they plan to transition to digital over time and do away with analog when the FCC allows it and their customers accept it. PCS, on the other hand, has the advantage of reinventing the wheel, since there's no embedded base of equipment. Unfortunately, there are something like seven different standards under consideration for PCS (including at least one GSM variant). > If most of this amount is funny money, "lost profits" that they never > really expected to generate, and use of excess capacity, then are the > phone companies crying wolf?

The carriers have tried a lot of things, from "electronic signatures" of phones that have to match a database entry to PIN numbers etc. The latest is the FCC's new rule, which the manufacturers hate, that requires the ESN to be unchangeable, period.

Jeff certainly can fend for himself in this forum, so this is just to add a little FACT to the fray. Butch, you were right -- Jeff was stretching the truth. The actual drop in Signal-to-Distortion ratio with 1/6 bit robbing between two switches is 1.8 dB, not 2. Of course, when there are 5 switches in the connection, the ratio drops by up to 4.2 dB. (5 out of 6 bits are affected on 10% of the calls, 4/6 on 40%, 3/6 on 40%, 2/6 on 10% and 1/6 less than 1%.) On a typical mid-length call (intraLATA toll or between adjacent LATAs), 3 out of 6 bits will be robbed 57% of the time and the ratio drops by about 3.2 dB. > I really doubt that the modems are affected by this as > much as Jeffery has stated. I would more believe than something more > common such as " ECHO " and several other more common impairments are > really alot more important than a occasional bit robbing. I agree that S/D ratio is not a BIG issue with modems, but it does place a small per-call variation into the connection -- and that could be just enough (combined with echo/cross-talk) to force a modem to back-off to a lower transmission rate. It is probably at least as much of a factor as the individual variation between two different modem lines at a common location. > There are also several new technologies such as fiber that have > introduced timing impairments such as " Jitter " into the equation. Jitter exists on all synchronous transport mechanisms, even ISDN lines. Copper-based, fiber-based, microwave-based, soliton-based all jitter. Whether it is a significant problem usually depends at least partly on the bit-rate, repeater design and bit-detection mechanisms. You seem to have it in for optical-based media -- what do you have against photons?

Darcos & Company, Silver Spring, MD USA Subject: Re: Cheap Way to Get an 800 Number? > Some friends and I are starting a new small business. We would like to > have an 800 number. How do I get one? You call a long distance carrier's 800 number and tell them you want one. Within a couple of business days they will turn on the number. > Other than ATT/MCI/Sprint, are there other people who can provide an > 800 number cheaply? Don't know how much you mean by 'cheaply'. My 800 number from AT&T costs me $8 a month plus usage, which is typically around 20-25c a minute depending on how far the person is from Maryland. As I typically have a low calling volume, the costs usually run only $12 a month or so. > How do I minimize my cost? First you have to figure how many calls you expect to receive. If you are doing a substantial number of calls now, you might see some of them move to the 800 number. If you see you are getting large volumes of calls, you can change your service to a different plan which charges slightly more for the service and less per minute. > How do I get 800-CALL-MY-BUSINESS? Do I have have to pay extra for a > "good" 800 number. I originally had Sprint for my 800 number. The number I wanted -- since my company name is "Tansin A Darcos & Company" -- the number I wanted to get was 1-800-TDARCOS. I couldn't get it; it was apparently reserved by someone else, even though calling it indicated that the number said it wasn't in service. The business line here is 301-587-6354. So, I got *that* number from Sprint, e.g. 1-800-587-6354 which is a nice idea. I checked later with AT&T when I saw their rate was fairly competitive with Sprint. Guess what: AT&T *was* able to give me 1-800-832-7267 (800-TDARCOS). So I moved to them. There was one item that I was not told, which suggest you ask all costs in advance. Sprint enabled the number I asked for -- the one that matched my telephone number -- for the fee of something like $10 a month, and included a listing with 800-555-1212 and even allowed calls from Canada; they asked me if I wanted to allow that, I said ok. When AT&T turned on the new number, there was an additional "installation" charge of $45. During a one month period, both 800 numbers from each carrier terminated on the same 301-587-6354 number so, unless a carrier has some rules against it, you can have multiple numbers terminating on the same line. Also, there is no longer an instate/out of state restriction. I can call my 800 number from another phone in the same room, or I can call it from Virginia (which is out of state but also a local call in this area). You no longer have to have separate instate/out of state numbers. And my bill shows the ANI of every call I've received, which occasionally includes calls from places like Texas or New York. Another thing to consider is who had your 800 number before; if it was in use by someone else recently. I used to have a big problem with my old 800 number I had a couple of years ago (this was before you could ask for a specific number); the former owner was a freight broker, so I got calls from long hall truckers across the country telling me about partially empty trucks available from point a to point b. I finally had to put an announcement on the line that said "Tansin A. Darcos & Company, a computer software development company." This is a point that is probably going to be a problem for the local telephone companies. Bell Atlantic will sell an 800 number for instate calls (it mentions this in the phone book); because of the long distance restriction they cannot provide interstate delivery. I doubt they can be much cheaper than a national carrier; if I can get an 800 number from Sprint for $10 a month that allows me to receive calls from anywhere in the US or Canada, why would I want a number that only works in my home state? About the only reason I could see is if you wanted a restriction on incoming calls from this state. But that's a problem too: within a 50 mile radius of where I am includes in MD: Baltimore, BWI Airport, all of Montgomery and Prince George's county, the state capital at Anapolis, parts of Howard County, but it also includes interstate areas including all of Washington, DC, Independent Cities of Alexandria, Falls Church, and Fairfax, Va; towns of Vienna and Manassas, plus Fairfax and Arlington Counties in VA, plus Washington National and Dulles Airports. If I want to reach anyone I can get to in a two-hour radius, an in-state only 800 number is worthless. In fact, most companies operating anywhere within twenty miles of Washington typically will operate in DC plus the cities and counties in both states surrounding it. For example, a large local plumber here lists one number to call in the greater Washington area: 1-800-4-HOT-WATER. I know they are licensed in all three jurisdictions. While they could probably take calls from Baltimore, or Arlington, VA, calls to them from, say, Dallas/Ft Worth or Los Angeles or Chicago would be worthless. Yet since they don't advertise there, paying more per month to block calls outside the local area probably isn't worth the extra cost, e.g if you get $3 worth of wrong numbers a month, paying an extra $20 to restrict area codes you don't want to service is not cost effective. ------------------------------ Date: Mon, 06 Feb 1995 10:54:58 EST From: Paul Robinson Organization: Tansin A. Darcos & Company, Silver Spring, MD USA Subject: Re: 28.8k bps Modem Victor Hu , writes: > I just purchased a 28.8 K modem with the brand "Supra". I paid extra > to get the 28.8 K instead of the 14.4 K. Probably about twice as much. 14K modems are down to $50 or so. 28Ks are probably in the $100 range. I purchased a 14.4 two years ago and it cost me $215. Consider yourself fortunate. Mine still works quite well -- I am using it to enter this message -- and like most modems, will be obsolete long before it wears out. If my Internet provider decides to upgrade to 28.8K, I will probably get one. Otherwise, since I can't use one yet, I'm not going to bother. > 1. Is the bps across the twisted pair wire actually running at 28.8 or > 14.4 when 28.8 is invoked? Or is it just data compression? The raw data rate for a modem will be from 110 to 28,800 baud (or 14,400 baud) depending on what the other side agrees on. The rate will be the lowest of whatever the two modems agree on. If you call up a service that has only 14.4 modems, or 9600 baud modems, or even 2400, you will only get 14.4 or 9600 or 2400 even though your modem can do more. If both modems are 28.8 and both have their highest speed enabled, you should see 28,800 baud before any compression occurs. The data is not sent at 28,800 bits per second, however. Typically the modem will divide up the telephone line into six or more channels, and run each channel at 2400 to 4800 bits per second. By multiplexing six channels at 2400 baud, you get 14,400 baud, etc. > 2. What kinds of host supports 28.8K? I only connect up to my > university's computer which only runs at 9.6K max. Your university may have so much load they can't run faster than 9600, or the terminal controller might not be able to handle it. Many mainframes can't do I/O faster than some otherwise slow speed by comparison. When a IBM Sierra mainframe came out, a 9600 baud modem probably cost as much as an ISDN BRI interface does now; hundreds or thousands of dollars, so the port controller was probably set up with that as the maximum. The school might not have money in the budget to upgrade modems, or the hardware might not be able to support those kind of speeds, or it could be the administration was waiting until the 28,800 speed was standardized by ITU, as some modems used proprietary methods to communicate about 14.4 and thus you might need the same brand at both ends. You might ask them if they plan to upgrade to 28.8 now that the ITU has standardized the method of delivering 28,800 baud. > 3. What is the speed of fax machines? There are two speeds for transmissions. First, when the connection is being set up, each side will send an identifier sequence. I call it the "answerback" after the similar sequence sent by a telex machine. This identifier sequence is called a TTI or CSI. One of these will typically appear in the log that the fax machine prints after 20-40 transmissions indicating the identifying machine. The other is the telephone number or other identifier that appears in the display window. The two items may be different. This information is transmitted by each machine at 300 baud, which is okay since it is typically no more than 60 characters for each side. The sending machine then increases its speed and the transmission takes place in the equivalent of "half duplex" mode, except that the recipient machine typically acknowledges the end of each page and end of transmission. The ITU standard for fax machine transmissions supports 4800, 9600, 12000, and 14400 baud, but typically a fax machine that does printing will do 9600 tops, and can be downgraded to 4800 if line conditions are bad. 12000 and 14400 are typically for fax modems in computers. > 1. The Supra has a nice display (external version for the PC) that > shows the mode of transmission. > 2. However, I found that it required a different initialization string > than that suggested as default for modems that are Hayes compatible. The strings for each modem are because they all do different things, and thus, to enable those features you have to set certain values. For example, you can do a feature called "port locking". Currently, my terminal program sends and receives data to and from my modem at a "locked" speed of 19200 baud. The modem will transfer data to and from the computer at 19200 baud, whether the connection at the other end is 110 all the way to 14400. The typical rule is to indicate every connection is at 19200. I can set a switch register and the modem will also report the actual connection speed. I can set a switch and have it enable or disable data compression, and I can enable or disable error correction. And I can set switches so that it tells me whether the other side allows or does not allow compression or error correction, or force error correction or compression. For example, when playing DOOM over a modem, the modem will run at 9600 baud (later revisions of the driver support 14,400). The modems must not use data compression or error correction (because the extra time to do this can lose synchronization between the two computers), and the setup string for my modem will specifically disable these features. At the end of the game, the driver will issue an AT Z HO to disconnect the line and reset the modem to the default settings. If I have caller ID service on a line, I can enable the modem to send the data after the "RING" message. I can enable the data in hexadecimal display digits, or I can enable it as ASCII text. I can also tell the modem to resend the last Caller-ID string it got, and I can tell it to resend it in hex or ASCII, even if I had already received it using the other mode. I can also turn off reception of Caller ID data. If I want the modem to send or receive facsimile data, the program must use the AT&F prefix with certain commands to tell the modem to either place a fax call or receive a fax. Every feature in a modem requires controls on it in order to enable or disable them as needed in a particular instance or application. Oh, yes, one more thing. The alleged claims of data compression giving throughput rates of 50+K and 110K on 14.4 and 28.8 modems is sheer fantasy. If you were sending a 100,000 byte file consisting of all spaces, or all the same character, you might see those kind of rates. On my 14.4K modem, on ASCII text files, if I use a locked port at 38,800 baud, and enable compression I can see transfer rates of as much as 3000 cps in rare cases, and typically around 1800 cps if the data compresses well. For binary and compressed ZIP archive files, I have generally seen average transfer rates in the 1600-1620 cps. For a 28.8K modem, you can expect to probably see rates around 3200-3400 cps, depending on the content of the material, if the other side uses a 28.8K and can stuff it fast enough to keep the line loaded. MCI Mail supports 14,400 baud on their dialins, but I typically see rates in the 700-1000 cps rate, probably because their VAX machines are heavily loaded. Occasionally I'll see rates as high as 1200 cps. ------------------------------ From: TELECOM Digest Editor Subject: New Archives Email Feature Date: Tue, 07 Feb 1995 01:00:00 CST Monday evening I installed a new feature in the Telecom Archives Email Information Service software called AREACODE. This allows the user to enter one or more areacodes and get back email telling where the code is located. This is just an additional command installed in the software, used in the same way as the other commands. You can insert as many areacodes as desired and get back responses on each one. If you are not already familiar with the Telecom Archives Email Information Service, you can request a help file explaining how to use the service. Send email to tel-archives@lcs.mit.edu. The subject does not matter. In the text of your message, at the left margin, enter these commands on your first use of the program: REPLY yourname@site HELP INFO END The REPLY command *must* be first, and END *must* be last. What you put in the middle depends on what you are seeking. The help file you will get in return explains the other commands. To use the new AREACODE command, it would look like this: REPLY yourname@site AREACODE 208 701 302 509 (or whatever areacodes you want to check). END Watch for a response in email, typically a minute or two later. Other interactive commands you can use are: SEARCH to search the back issues of the Digest for subject and author names since 1989 forward. GLOSSARY to search the several glossaries on line in the Archives checking for abbreviations and telecom terms you want to learn about. The help file will explain it all when you order it and INFO.

The author waffles around with terms like "vehicle for the delivery ... of ... multimedia," but the reality is that the phrase was and is a speech-writer's icon. The slogan is very environmentally friendly: it has been reused in ever-broader situations, recycled in more promotions and speeches, and, in the process, reduced almost to meaninglessness. Goldsborough, in common with many who have only a tenuous grasp on the concepts, attempts to marry the widespread, anarchic, and still experimental Internet with the tightly-controlled "providers" of electronic media. (He also attempts to expand the collection of information supercliches with "infopike". Since he uses this to draw an analogy to the toll-road turnpikes of the northeastern United States, it is easy to see where his sympathies lie.) The book is a collection of enthusiastic essays about life in the telecom- rich future, with a piece concluding each chapter by some politician, "industry leader", Famous Person, or other "expert". Sometimes, it's hard to determine whether the "viewpoint" is an addendum to the chapter, the chapter is an introduction to the viewpoint, or whether both are related solely by proximity. The author must be sensitive, in advance, to possible charges that this material is all very "blue sky". After the opening story, he argues that this is not a fantasy, but that future technology will be very much like it. Of course, the technologies presented -- email, multimedia extensions, teleconferencing, voice recognition and macros -- are all available *now*, but it is obvious that Goldsborough is not really experienced in the most effective ways to use them. This is an extended series of the usual mass-media magazine articles, high on "gee whiz!" and low on content. copyright Robert M. Slade, 1994 BKSTINSH.RVW 941226.

With the service, called GlobalRoam(SM), a traveler's cellular roaming capability will ultimately be expanded to most countries in the world. "American business travelers will have the same communications mobility from country to country as they already have domestically from city to city," said Jerry Waylan, executive vice president-product management and business development, GTE PCS. "Our research clearly indicates a need and desire for this service." In 1993, 3.7 million business people traveled between the U.S. and Europe," said Roland Mahler, executive director of product management mobile telephony services, DeTeMobil. "As the marketplace becomes increasingly global, we are making sure that business communications are keeping pace." Through this agreement, each company will have its own gateway to provide interoperability between their two different cellular transmission standards. GTE, along with all other carriers in North and South America, uses analog cellular radio technology known as the AMPS standard, which stands for Advanced Mobile Phone Service. Most other countries in the world have adopted a digital cellular system known as the GSM standard, which stands for Global System for Mobile communications. Deutsche Telekom, the parent company of DeTeMobil, played a leading role in the development of GSM. Initially, DeTeMobil subscribers will have access to North American cellular services. Through international roaming agreements between DeTeMobil and other GSM network operators, North American subscribers, through their local carriers, will be able to use worldwide GSM networks. In the summer of 1995, GlobalRoam will be available in more than 30 countries, and will eventually be expanded to include countries with other cellular standards. GTE PCS will market the service initially to large U.S. corporate customers and then to North American cellular carriers including GTE Mobilnet and Contel Cellular, who will offer the service to their customers under the GlobalRoam service name. DeTeMobil will offer GlobalRoam to GSM cellular carriers. Subscribers to the GlobalRoam service will receive a "smart card," programmed with an identification number and other customer information. For travel outside the U.S. and Canada, they will purchase or rent a GSM mobile phone that accepts the card. The phones will be available for overnight shipment. When subscribers use the phone in a foreign network, calls to their home cellular phone number will automatically be directed to their GSM phone, which will operate in any country where DeTeMobil has a roaming agreement with the respective network operator. "Ultimately, we expect manufacturers to develop dual mode, AMPS/GSM cellular phones, which can be used at home as well as in other countries," Waylan said. All charges will appear on the customers "home" cellular phone bill as international roaming charges. The GlobalRoam service will be made available to cellular carriers at a flat wholesale rate, per-minute airtime charge, plus toll, and a one-time activation fee with recurring monthly charges per subscriber. Cellular carriers can then retail this service to their subscribers. Additionally, as an option, the carrier can provide to North American travelers a debit "smart card." A $100 debit card, for example, would cover the cost of $100 in airtime and toll charges. The debit card will initially be available for use in Germany. GTE Telecommunication Services Inc. (GTE TSI) will facilitate this service by providing the AMPS/GSM gateway in North America. In addition, GTE TSI -- which provides advanced software services to the wireless industry -- will provide billing record translation and clearing services so that charges for the international roaming service will be included on customers standard cellular telephone bills. For additional information on this service, call 1-800-798-ROAM. Deutsche Telekom Mobilfunk GmbH (DeTeMobil), headquartered in Bonn, is a wholly-owned subsidiary of the Deutsche Telekom AG, dealing with mobile communication services. The company is Germanys largest provider of these services and one of the largest in Europe with more than 2.2 million customers at the end of 1994. DeTeMobil is the operator of the digital network D1 and played a leading role in the development of the successful international GSM standard Global System for Mobile Communications.

If you have caller ID, you have probably grown very attached to that "reassuring" feeling of knowing that the person at the other end is not a telemarketer, or similarly disfunctional individual, but rather you best friend Bob. Now, the problem is that if you are on the phone and someone calls in, you get the call waiting beep but no indication of who the second caller is. Caller ID is not applied to the call waiting service. Is there a reason why caller ID cannot be used with call waiting? I would pay dearly to be able to get call display and name display working with call waiting. (I am a Bell Canada subscriber, but I suspect this problem affects more than just us Canucks). Evan [TELECOM Digest Editor's Note: There is a two-part answer here. The first part is why it cannot work, and the scond part is about how it will soon be changed so it does work. The present arrangement is that the data has to be sent when the phone is on hook. If you are willing to disconnect your call in progress and hang up completely (rather than just flashing the hook and putting the first party on hold) then you *will* get the CID for the new call. The data gets sent to your box between the first and second *actual ring at your end*. This means it could 'ring' five times in the caller's ear and you would get a couple of call waiting tones. You finally tell your caller you want to see about the other call and will call him back later. You disconnect and the call waiting starts ringing at your end. Watch your ID box; the calling number will show up there immed- iatly. The ID comes between the first and second ring *you hear* from the actual bell on your phone. Now if it is someone you do not want to talk to, well, you are sort of stuck at that point. I guess you let it ring through to your answering machine or voicemail. That is another curious point: Even though you have voicemail you might have noticed that the call waiting won't transfer there after three/four rings like other calls. Well, it will, but again, its after three/four rings *that you hear* -- not the artificial 'rings' the caller gets in his ear. A sophisticated caller who knows that he always gets your voicemail after three/four rings calls and it rings ten times in his ear *then* he gets your voicemail realizes you were there, and on a call, and chose not to take his call once you saw who was on the ID box. That is going to change however. We had a report here not long ago about 'Caller-ID on Call Waiting' (I believe that is what it is called) and how it will be implemented later this year in many places. My understanding is you'll need to have a special kind of phone to make it work. It will work sort of like call waiting does now, where the central office gets on your pair, and for a split second breaks the path to the person you are talking to in order to send the spurts of tone. Its going to do that same kind of thing with Caller ID on Call Waiting in the future. Existing display boxes and phones will not be compatible however. Would whoever sent in that report send it again as there have been others asking.

Weil" >>> The number for the store in Rockford was curiously 8-22-47. I'm >>> too young to know anything about 5 digit phone numbers. Is that >>> how it was back then in small cities? Gee, all this talk of 5-digit numbers makes me feel old! I grew up in a small town in western Pennsylvania, and in the late 1940's, our phone number was 849M. No idea why the "M" instead of a fourth number, but the line was a four-party line (private lines were extremely rare -- most everybody I knew had a party line). The phone would ring when any one of the party-line subscribers were called ... each had his own distinctive ringing pattern. Ours was two longs and two shorts, or some such thing. The only way to tell if the line was in use was to pick up the receiver and listen. One of the other subscribers on our line had a daughter quite a few years older than I, and I must admit that I didn't always hang up when I heard her on the phone. Never listened long, though, because I found "girl talk" boring ... "mushy" was the word used in those days, I believe. "Crossed connections" were not uncommon in the days of mechanical CO's (anybody remember the cats' eyes?), either, so we frequently got to listen to conversations between other subscribers, as well. No taps, no bugs, no scanners: the telephone was a source of entertainment as well as a means of communications. I don't know what the laws were then, but I probably committed my first felony, or at least misdemeanor, before I was five years old! As we got older, we found another way to use the phone for entertainment: "prank" calls. Call the local drugstore ... "Do you have Prince Albert in a can?" ... 'Yes, we do.' ... "Well, you'd better let him out before he suffocates!" Such shenanigans are a thing of the past, killed by ANI, CID, auto call-back, auto call-trace, and the like ... perhaps it's just as well. [TELECOM Digest Editor's Note: For those unaware, 'Prince Albert' was a type of smoking tobacco used in a pipe. I guess they still make it. The other variation on this was to call someone late at night and claim to be the Electric Company, asking 'is your refrigerator running?' Some fools would actually put the phone down and go into the kitchen to see, then come back and say it was. "Then you better stop it before it runs away and you never see it again ...". To five and six year old children, those jokes are very funny, especially when played on an 'old person' late at night, after the 'old person' was already in bed asleep and the child should have been but wasn't. The 'M' (like J, W, and R) were just keys to tell the operator which party on the line was to be rung. The switchboards had four buttons marked M,J,W,R and the operator would press down on one of these buttons while pulling the ringing key. Whichever one she pressed sent the current one way or another down the party line to ring the one bell, and only the one bell similarly wired. Other places had the 'short/long' ringing system as you mentioned, where all bells were wired in common, and the subscriber was relied upon to know which to answer and which to ignore.

The way it was explained to me was that 33 was our line I grew up on a farm outside a small Kansas town, with manual phone lines run by Southwestern Bell. I still have a yardstick from the local lumber yard with "Phone 37" on it. Around 1959 they put in a small SXS CDO and dial phones. And everybody got a four-digit phone number in the block of 32xx to 35xx. Since business (and businessmen's homes) had all the two-digit numbers, they were converted to the 32xx block by prefixing "32". So the lumber yard got 3237 and his house got 3236. His widow still has that number. Southwestern Bell replaced the SXS in 1993 with a digital switch, and forced everyone to seven-digit local dialing. Virtually every business still has a NXX-32xx number. (The fire department has 3210.) For my home town, the current phone book (6" by 9" format) has just over three pages. My dad has the distinction (since his mother died in 1980) of being the only "V" entry.

I was told that that number was not being used, and they would do whatever would be possible to get me that number. For the next months, I called and called to check up on the status of the 500 assignments. Well, on Jan 3,1995, I ordered my 500 number which was scheduled to go into service on Feb 3,1995. Then my 700 number was supposed to be cancelled at the same time. Well in late January, my number was working, but someone else was answering the call. I called AT&T, and they told me to just wait until Feb 3, and it should work then. Yesterday was Feb 3, and I called them. They were going to assign my 700 master pin to my 500 number that evening. I called back later to ask a question, and now they had NO RECORD EVER of me ever wanting a 500 number. I was informed that the 500 number belonged to someone else! NO RECORD OF ANY CONVERSATION! NONE!! NADA!!! They told me they were sorry, but there was nothing they could do. Believe me, I was very upset. Not just losing my number, but not having any record of talking to them. I kept asking them about all the literature I have that I requested! It's got my name, my address, etc. They set me up a new 500 number in 55 minutes. It went from a month to 55 minutes! My voice mail still doesn't let me in, and they keep trying to fix it. United Telephone doesn't know how to bill the 500 call, so I must use a calling card. MANY MANY little things ... I know that "my" 500 number terminates in NY, and that I believe that person also had 0-700-MATTHEW. It wouldn't suprise me if he worked for AT&T (since their headquarters is located at 195 Broadway). It's just very very very weird for all information about my 500 number to be GONE! VANISHED!.

Very possibly the computer was 'down' when you called and they could not 'find a record' of any previous calls. Sometimes when they are without computer they try to bluff as they go along ("I don't have all of your records available to me right now ..."). What you are saying could be true, but I have never seen them quite that bad, that they lost everything. In other news, *my* 500 number started working perfectly today. About 3 PM Monday I tried dialing 0-500 and 1-500 and as before, got nowhere. But I had already found out both versions work fine from Chicago. I called repair service on a lark and ask them 'when is 500 going to be unblocked?' I got a call back within ten minutes from a woman very eager to hear all about it. She insisted all was working fine. "Not in the Skokie CO," I told her. She seemed astounded to hear that but said she would look into it right away. Another five or ten minutes goes past and she calls me again to advise "I fixed it. The translations were not loaded is all ... you can use it now." Of course I tried it immediatly after disconnecting with her, and sure enough, it worked fine, twenty minutes or less after calling repair service. Amazing ... absolutely amazing. An interesting side to this is when I use my own phone to dial 1-500-677-1616 (my number) it rings once and I am told it will try my alternate numbers (because it found my home number to be busy). When I do 0-500-677-1616 and tell it to bill the call to the phone I am using, it vanishes for a couple seconds and I get call-waiting, then after four rings (call waiting or not) it interupts and a voice message says it will try my alternate numbers. I did not bother with AT&T voicemail; I have voicemail up the kazooey from a few other places I rarely use. Anyway, feel free to call me at any reasonable hour: 500-677-1616.

I don't know a single person who doesn't flip the station when a long distance advertisement comes on. In my opinion, Sprint is the real winner now, with their penny-per-minute promo.

If that is their savings on $1/minute rates then you are getting taken to the cleaners. Percentages do not matter as much as the bottom line which is the rate you are paying. Find out what those are and then you can make a viable comparison. I have flat rates around 14 cents/minute on my home line with a carrier. I have seen better rates from resellers, but I just can not trust them with my phone service. Anyone in the US can get these rates and businesses will often times get better, if not much better, rates. Also, do not get a calling card if it has a surcharge or any hidden fees such as higher first minute billing. Ask for nothing less than straight six second billing. You should only be paying for what you use, right? I hope this helps. :-) Regards, Christopher H.

Kobb) Subject: FCC Allocates Data-PCS Spectrum Organization: New Signals Press Date: Tue, 7 Feb 1995 22:31:31 GMT Here is the news release issued by the FCC today on the 2.4 GHz allocation. (The full text of the decision has not yet been released.) Congratulations to all concerned for a job very well done. Bennett Kobb bkobb@newsignals.com Editor and publisher Spectrum Guide Federal Communications Commission NEWS February 7, 1995 Action in Docket Case (ET Docket No. 94-32) The FCC has allocated 50 Megahertz of spectrum, at 2390-2400 MHz, 2402-2417 MHz, and 4660-4685 MHz, that was transferred from Federal Government to private sector use. The allocations adopted by the Commission today will benefit the public by providing for the introduction of new services, such as wireless local area networks, and the enhancement of existing services. Among other things, these services will allow companies to operate more efficiently by communicating through wireless networks that are flexible enough to operate almost anywhere. They also will allow low cost access to Internet services and other information networks for schools, libraries, telecommuters and home offices. In addition, these services will allow for better health care through wireless health care monitoring devices and allow the instantaneous updating of health care records and databases. The Commission stated that this 50 MHz is the first of at least 200 MHz of spectrum required to be reallocated from Federal Government to private sector use in accordance with the Omnibus Budget Reconciliation Act of 1993. The Budget Reconciliation Act of 1993 required the Commission to adopt allocations for and propose regulations to assign this first 50 MHz of spectrum by February 10, 1995. The Commission allocated the 2390-2400 MHz bad for use by unlicensed Personal Communications Services (PCS), provided for continued use of the 2402-2417 MHz band by unlicensed devices operating in accordance with Part 15 of the Rules, maintained the availability of both of these bands for use by the Amateur service, and allocated the band 4660-4685 for Fixed and Mobile services. The Commission stated that unlicensed PCS devices, which include wireless networking and data transfer devices, operating in the 2390-2400 MHz band will be governed by the same rules that apply to PCS devices operating in the 1910-1920 MHz band. Power levels, emission limits, and spectrum etiquette for unlicensed PCS devices operating at 2390-2400 MHz are identical with requirements for asynchronous (data) devices operating at 1910-1920 MHz. The Commission believes that allocating the band for unlicensed data-PCS, and providing for use of 2402-2417 MHz by Part 15 devices, will provide for the continued development and implementation of a new generation of advanced communications devices and services, such as wireless local area networks, digital cordless telephones, electronic article surveillance equipment, utility metering devices, fire and security alarm devices, and wireless bar code readers. In addition to offering the potential for providing greater safety and security to citizens and allowing business to operate more efficiently, this new family of devices offers the potential to directly benefit a large percentage of the public by providing a new "on-ramp" to the information superhighway. Corresponding to the Fixed and Mobile allocation for the 4660-4685 MHz band, the Commission proposed technical, assignment and service rules.

They won't see the utility, and may even be suspicious that it's "like 900". * Other carriers will not charge the same rates for calls to NPA 500.

John [TELECOM Digest Editor's Note: AT&T sets the rates (or whatever company offers the 500 service, such as Ameritech also proposes to do) for calls since you are connecting to them. It is much like calling an 800 number in that the billing is done by the company whose prefix you dial into. All your local telco will be doing is handing the call off to AT&T (or other 500 carrier.)

However, my company has looked into many environments over the past year and have, so far, found only one that seems it will be suitable (when it's completed). A full featured application out of Florida is called Dimi/TAS. Agent stations are MS-Windows (or ...) clients connecting to a central server or more. I've reviewed AmTelco's Infinity system where telephony and data are on seperate networks altogether, using MS-Windows DDE capabilities to automatically hot-key between the two nets. We're familiar with Eve, Startel, TASCOM, others. But, our call center environment is too large for entry-level network topologies. We look like this: _______ |-------| Fiber | | __| MUX | | | |_______| T1's, ISDN, # Call Center | | Other WAN Server 1 | | (FDDI RING #1) Connections | * Router ||| # Call Center | (Firewall) # Communications ||| Server 2 | Server ||| | ||| (FDDI RING #2) # Call Center | |----| ||| Server 3 | | |Modem Pool ||| |____| |(192 ports)________ ** Bigger Router @@@@@@... |____| (Firewall) 65 Agent Stations Beyond that, we have used the telco approach with -48 volt power supplies, everything is redundant, we generate our our AC and have a large natural gas generator for when and if city utilities go out, a wall of batteries dual-homed/dual-attached/dual counter-rotating ring FDDI switches connecting the servers and dedicated 10Mbps Ethernet going to each Agent Station. One Call Center Server is a fault-tolerant Tandem. We have many T1 spans and have been in business for 58 years. We just don't need an entry-level topology, as you may see. What we do need is a client-server based product that will run well on 65 Windows-for-Workgroups clients, and understand Tandem's CAM (for telephony integration, screen pops, etc.). The product we need incorp- orates functions of an answering service and a call center (message taking and order taking), with the ability to send data out via fax, remote printer, PC pickup, etc. Who knows such a critter?

This article should be required reading for anybody who wants to enter into the debate. I think the definitions and framework are a valuable starting point. Malcolm ----------------------- Caller ID and the Meaning of Privacy Laurie Thomas Lee (Univ of Nebraska-Lincoln) Robert LaRose (Michigan State) The Information Society, Volume 1, pp 247-265, 1994. Caller ID service continues to be controversial issue in the U.S. because of its privacy implications. State and federal regulators, legislaters, scholars, and the courts have examined and responded to the privacy issue from a policy perspective, but perhaps without a complete understanding of the meaning of privacy in the context of the debate. What types of privacy are involved, how signifiant are these interests, and how might privacy needs compare and be balanced? This article explores privacy in the context of the Caller ID debate from a social science perspective. It examines motives for seeking and preserving privacy and explores the dynamic relationship between the caller and the called party positions. It then provides an analysis of current and proposed Caller ID features and policies with a view towards understanding how these proposals balance competing privacy needs. This article establishes an analytic framework and a foundation for further study of caller and called party privacy that should lead to a better understanding of the privacy debate and the privacy implications of Caller ID. ------------------------------ Organization: Megalith Mail/News Server - Miami, FL USA Reply-To: overlord@megalith.miami.fl.us From: overlord@megalith.miami.fl.us (Carlos Amezaga) Subject: Special Alert! Unreasonable Network Policing Proposed Date: Tue, 07 Feb 1995 20:57:00 EST -> EMA ALERT <- News For and About the Members of the ELECTRONIC MESSAGING ASSOCIATION ============================================================ February 3, 1995 -- Number 18 <----------------------------------------------------------> ***** SPECIAL ALERT ***** - Congress to consider making all system operators liable for messaging content. Bill would force employers to monitor message content. ACTION NEEDED NOW! <----------------------------------------------------------> UNREASONABLE NETWORK POLICING PROPOSED Yesterday, Senator Jim Exon (D-NE) introduced S.314, the Communications Decency Act of 1995, in the United States Senate. In an effort to stamp out digital pornography, it makes all telecommunications providers doing business in the United States (from the telephone companies all the way down to offices that use LANs) liable for the content of anything sent over their networks. To avoid the possibility of tens of thousands of dollars in fines and up to two years in jail, business owners would be forced to police their networks and monitor in advance all messages sent over them. WITHOUT ACTION - COULD BE LAW IN MONTHS This bill is substantially the same as the one he put forward last year. He will offer it as an amendment to the pending telecommunications deregulation legislation in the U.S. Senate, which is expected to be enacted by July. Last year, his amendment was adopted even though many thought it hastily drafted and poorly thought out. Fortunately, the telecommunications deregulation legislation died. This year, a more conservative U.S. Congress may be even more reluctant to challenge a "morality" amendment; and its legislative vehicle, the telecommunications deregulation legislation, stands a much better chance of passage this year. ACTION NEEDED NOW Action by the business community is needed now. Please notify your corporate government affairs office and/or your legal counsel. This measure could be adopted as an amendment to the telecommunications bill IN A MATTER OF WEEKS (or potentially added to any legislation pending on the U.S. Senate floor), if business does not mobilize against it. S.314 will not stop digital pornography, but it could devastate the messaging business.

Date: 7 Feb 1995 14:44:15 -0500 Organization: Project Glue, University of Maryland, College Park Recently an "urban rumor" has been going around: If you want to know whether your phone has been tapped in the last six months, dial in the following: 107 321 404 988 966 4 What you will get back is a digital recording consisting of (a) your phone's area code; (b) your 7-digit phone-number; (c) the digit 8; (d) a pause of a few seconds; (e) 9 zeroes in three groups of three -- 000 000 000; and (f) a digit. If the digit (f) is a 2, your phone is clear. Otherwise, if it is any other digit (usually it's a 1 in that case), your phone has been tapped in the last six months. OK - obviously this number is 10732-1-404-988-9664. Which provider is the 5-d code 10732? Anyone know mroe details on the 1-404-988-9664? Thomas [TELECOM Digest Editor's Note: Gosh, what a mystery! If you will be so kind as to dial 10732-1-700-555-4141 the recording which answers will tell you that you have reached 'a private network', and that if you want to get more information you can dial your account representative. For anyone wishing to make a call, we are told to dial (here comes the clue!) 10288 and the number. 10732 is used by AT&T's largest customers. I don't know everything about it that makes it different than 10288, but it does have a few things different. In case you had not noticed, 404-988-9664 cannot be dialed via any other carrier. You can try it; all you will get is a busy signal. This tells us that AT&T is grabbing incoming calls to that number via 10732, intercepting them and delivering them somewhere (probably to themselves at their office in Atlanta) on a T-1, and that the actual phone 988-9664 is just left off the hook all the time. After the recitation of your phone number -- or more precisely, your ANI -- then your account number is read back. It is all zeros because you don't have an account with AT&T, at least not where this particular network is concerned. I don't know what the final digit is, but that bull about 'your phone has been or is being tapped' is just exactly that: Bull! How would AT&T know if some customer of Sprint (for example) had his phone tapped by his local telco, at (for example) the request of law enforcement. Whoever spreads these stories (you perhaps? 'urban legend', indeed!) should stop it now. I don't know what the AT&T private network uses that number for, but I can almost assuredly advise you it has nothing to do with phone taps.

We want to integrate with our NEC2400 PBX, which has an RS232 connection they call Infolink which provides realtime status information from the ACD processor to external IVR equipment. Apparently,it is an open application and NEC will provide documentation. Our initial application is pretty simple--we want to provide queue status information to the caller, and allow the caller after a predetermined time to exit the queue to voice mail, or be returned to the queue. Commercial IVR companies offer systems but want about 40K to do this. I would like to contract with an experienced developer to do this for us if we benefit from it.

Years ago, when I first moved to Baltimore, Maryland, I was living in a pretty rough, run-down neighborhood. The only building of any size was a C&P (now Bell Atlantic) CO that towered over the area. To protect vans and other company vehicles, they were parked overnight in an adjoining enclosure, surrounded by a chain-link fence topped with barbed wire. As an additional safeguard, there were two very unfriendly guard dogs released in the enclosure overnight. That continued for about a year after I moved in. The practice ended when, one night, someone stole the dogs ... Dale Neiburg, STC National Public Radio Phone: 202-414-2640 635 Massachusetts Ave., N.W. Washington, D.C. 20001 Internet: dneiburg@npr.org [TELECOM Digest Editor's Note: Dogs make excellent security assistants. The City of Chicago has an auto pound over at 30th and California Avenue right behind Cook County Jail. Anyone whose auto is towed out of a place it should not be parked, along with autos which were stolen, stripped and then abandoned on a street somewhere wind up there in the city auto pound. It is a dreadful place. Along with high barbed wire fences, signs warn against trespassing and caution that vicious dogs roam the premises all night. So walking down the sidewalk past there at night, or a Sunday afternoon or other time when the place is deserted, you see these mountains of stripped, rusted out cars, piles of tires and motor parts everywhere, and three or four really vicious, nasty German Shepherds who constantly jump at the fence, growl, bark and bare their teeth at you as you walk past. You can see the hatred in their eyes. Occassionally, I am told, some fools still climb the fence at night, go in and try to strip an auto left there by the police towing or just outright steal it. On the other hand, it is *good* seeing the dogs with the security people on the subway and elevated trains at night. The rate of crime on public transportation at night -- violent or non-violent -- has gone down quite a bit as a result. Those dogs are kept on a strong leash/strap, with wire muzzles around their nose and mouth so they cannot just go up and take a bite out of someone. But let one of them stand next to you on the train at night looking at you; you *know* the dog would love to take a bite out of your leg if he could. Consequently, people are behaving themselves quite nicely on the subway these days, or rather, these nights and early mornings. Coming home from downtown Chicago on a Saturday night, I went in the subway at Jackson Street about 1:00 AM. Nothing surprises me there; that station is like a zoo at night all the time. A very tall man who appears to be intoxicated and high on something has finished drinking beer. He smashes the bottle on the concrete floor and holding the bottle by its neck is menacing anyone and everyone there with the broken peice of glass. Someone has told the fare collection agent upstairs about this and she has started frantically ringing the security bell; very loud bells with big gongs wired in parallel in all the downtown stations. She presses a doorbell button in her cage with a certain cadence to produce a ringing signal on all the bells to say which station needs assistance. Meanwhile downstairs this fellow is on a rampage, screaming and cursing and threatening anyone who comes near him with that broken bottle he is waving and the overhead bells are ringing loudly, two short, one long ... two short, one long. A woman who is one of the Chicago Transit Authority security representatives comes up about that time with Bruno, her dog. She has no gun, but she does have a club I would hate to be on the wrong end of. She stands about ten or fifteen feet away from this guy and looks him right in the face and yells at him: "You scum! Put down that bottle now! Toss it out on the track! He looks at her and stands there. "I told you to put down that bottle! Sit it down there on the floor or toss it out on the track!" Instead of doing either, he starts toward her waving it. In about two seconds she had bent down and pulled the muzzle off Bruno. All the dogs are trained to respond *only* to a word said by their owners. The word is obviously not 'kill', because all sorts of practical jokers on the trains look at the dogs and say that to them; the dog just keeps watching them, but does not respond. In Bruno's case, the secret word was 'love'. "Go love, Bruno! Love!" To the dog, this meant great fun was at hand. He lunges at the dude, knocked him over and was snarling and fighting with him as the woman kicked the beer bottle out of the way and handcuffed the guy. About this time, Chicago Police tactical officers arrive to back her up; they hussle the guy off into the catacombs, some of the odd, desolate little rooms in the bowels of the subway which connect with the remains of the old tunnel system from a century ago. They take prisoners there to 'interview' them sometimes, and no doubt to administer discipline on the spot, knowing quite well that in our overcrowded court system, the only punishment to be meted out to miscreants on public transportation -- the purse snatchers, pick pockets and others -- will be the punishment afforded them by the police officers who arrested the 'asshole', as in "The asshole was threatening other passengers with a broken bottle. My dog had to take him down ..." It doesn't quite go in the official report in those exact words, you understand. ....

Although there are a few impressive features on the system, overall, many people can NOT reach me on it and/or find it awkward. Here are some observations: 1. WHY does it have to say "AT&T" when someone calls 1-500-442-4CID? I don't need people calling me to hear free advertisements for AT&T. I realize that people may wonder why there are AT&T 500 charges on their bills when they may use MCI or Sprint, but having the service say "AT&T" for every call is annoying. Put the info on the bill if needed. 2. Configuration is the same as the 700, ie, I dial 0-500-442-4CID, and enter my PIN. The menu is exactly the same for the "middle" tier service, and is slightly more complicated for the higher-end ("Navigator"?) service. BUT - dialing 0-500 is also the problem. From a cellphone, you need pay for this. I don't want to have to pay each time I want to re-forward my calls to my cellphone, or from one phone to the other. There is really no technical reason why AT&T has to return supervision on 0+500 calls (or 0+ calls in general)...I mean, so if it doesn't work on the last remaining Step-By-Step exchange in Vermont or whatever, fine, but I think there are good deal more people using carphones than served by SXS exchanges where 0+ tone dialing requires a supervision return. The service is useless to me if I need to re-forward it and have to PAY each time I do it. I have no problem paying for use, but to pay airtime to my cellco just to reforward calls is too much. I know you can schedule it to try a few numbers, but I'm not always at the same carphone, and I suspect there are a number of poorly connected cellphone companies where AT&T's system will not be able to tell if the line is busy or no one is there via any other method than a timeout. We intend to use 500-442-4CID for business purposes, (or we'd like to), but if it is too flaky and/or costly to use we just won't bother. 3. Caller ID isn't shown (no surprise there). 4. It doesn't work from Rochester, NY, and all these other telcos which couldn't bill the 700 number directly, either. It doesn't work from most people's PBXs, and it doesn't work from any sort of system which is not directly connected to the local telco, like an outdial from a voicemail box, etc. 5. Most cellular companies do not allow 1+500 billing (even those which AT&T owns), so you need to dial 0-500, resulting in an airtime charge to the caller even if no one answers or the line is busy. This was one of the biggest problems with ER700 -- no one wanted to call me from their carphones after about a month of using the service and seeing all these calls at 80 cents per minute to my 700 when I never even answered. There are other significant problems, but I'll save those for another post. What I do like about the service (and this is more of a result of how 500 numbers work than anything AT&T has done) is: 1. I can tell everyone to just dial 1-500-442-4CID. If it works from your home phone/business phone, great. If you are at a payphone, you can STILL dial 1-500-442-4CID, and it automatically dumps you into the 0+500 menu. This way, people don't have to know 0-500 or 1-500, they just always dial 1-500. (It would be nice if payphones would let you pay for 1-500 with coins, at least for AT&T 1-500 calls.) There is no need for any access codes, alternate instructions, 10xxx codes, or anything. 1-500 does the trick! (Assuming it works at all, which, from many phones and businesses, it does not). The usual problems with having to use the silly 800 number to access the 500 number still apply to many cellular services, most businesses, etc. Most of my friends can't call me from work, so I wonder about how worthwhile the service is for personal use, let alone for business use. 2. I can forward my calls to my 500 number, which although not something which I would often do, is still a feature which the 700 lacked and which would have come in handy from time to time. 3. You can give your callers PINs if you want to pay for the call. This is also a welcome feature carried over from EasyReach 700. Unfortunately, it's also necessary - without giving out PINs to some of my callers, they would NEVER be able to reach me. They call from locations where they need to use the 800 access method and calling card, and do not have AT&T or local Bell calling cards. So because the 500 service is STILL difficult for many people to reach, *I* am forced to pay to allow them to reach me. I had hoped the 500 service would alleviate all this - apparently, it does not. Although a number of these features are an improvement, AT&T needs to do a LOT of work before their 500 service becomes useful enough for me to justify the $7 monthly "Navigator" charge, or even the $4 "middle service" monthly charge. Right now, it is a partially fixed 700 service, but does not go far enough to remedy the major deficiencies of ER700. If there are any other carriers out there who offer a similar service but without all the problems of AT&T's, I'd love to hear from you! BTW - Can International callers access the 500 service by dialing +1-500 etc? I'd be interested in hearing about this as well. (I don't mean via AT&T's thoroughly overpriced USADirect service, rather, I mean as a direct dialed call to the US.)

Here is why: I was awakened twice during the night (Wednesday early morning) on calls from Europe where people were trying to reach my 500 number -- the only number I give out now. About 5:50 AM Chicago time the phone rang. Someone in London was calling to say someone *they* were dealing with was trying unsuccessfully to reach me and could I advise how to get through. I was too groggy to speak with them for more than a few seconds. Then about 8:00 AM the phone rang again, this time with *someone from AT&T* on the line. He was in New York, and said he was working 'with a customer calling internationally trying to reach me'. So what, I asked ... and this guy (an AT&T employee!) asks me, "What is a 500 number?". Sort of astounded, I asked if he was indeed an AT&T employee and he said he was, but that he had never heard of 500 numbers ... and he worked for the company! I told him it was called 'Personal Number Service'. He wanted to know how callers from international points 'were supposed to get through' and I told him damned if I knew anything about it, I am just an ignorant cust- omer. I suggested maybe they could try USA Direct and see if that worked. That should keep a few people at AT&T occupied and busy today. Then I realized one way to force everyone to call you via AT&T whether they want to use that company or not is by giving 500 as the only possible number to reach you on. Let them argue about it with their telcos, etc. This should prove to be a great help toward maintaining the privacy of your phone number when it is requested on credit applications, etc. No fraud is intended of course .. you *can* be reached via 500. All you have done is just made it a bit harder for folks calling from PBX's and via lame telcos, etc. Plus, its so new, it will still be a novelty for quite awhile ... so let's all give 1-500 as our number; our only number. Either use it or don't get through. Forget the 0-500 unless the person thinks of it on his own as a way to call using a credit card. I certainly do not intend to give out any of those PINS for collect calls to me with the exception of my very immediate friends, etc. I am having lots of fun with this already!

I've wondered this myself. I'm with Bell Atlantic Mobile, which has the same system. One thing I've found out though, you don't have to wait for the tones before you press in your PIN, just make sure the tone sounds before you press SND. Regardless, I hate the entire PIN thing. I don't know why I assigned one to my number. In addition to the above concern, it messes up your last number redial. When I RCL my last number, it's the blasted PIN.

At the time, I had also received the promotional flier advertising rates 10% lower than AT&T. These rates were available by dialing the appropriate access code. I have used the code for several calls between NJ and Texas, making calls at times-of-day similar to calls I had placed with AT&T (my "normal" long distance carrier). I received my bill yesterday, and, true to its word, the Dial-N-Save reduced my long distance charges by a little more than 10%. The average call rate went from about $0.17 per minute to about $0.153 per minute. Rates for nite/weekend were a little lower. Other than waiting a couple of seconds longer for ringback, there was no discernible difference in quality.

For example, Hospitality Services Group has a personal 800 program whereby a person can get a free (and true) 800 number with no montly fees, no setup fees, no minimums, billed in six second increments and only 18 cents per minute, all the time. There are also other 800 services one can get at much lower rates if they volume warrants it.(usually over $50 per month.) And the rate can be as low as 13.5 cents per minute flat rate, billed in six second increments. And if you have a vanity number you can transfer and keep the same number and pay lower fees.

I have been deluged with email requests about ADSI, so here is more detail on how ADSI actually works, as well as all the applicable Bellcore standards. The future of Caller ID lies with ADSI. The acronym stands for Analog Display Services Interface, and it is really a series of Bellcore documents that lay out the new standard. I have received several requests for the names of these standards, which are all covered in Bellcore FR-NWT-000012. They include: TR-NWT-001273 TR-NWT-000030 SR-INS-002461 SR-TSV-002476 SR-TSV-002697 SR-NWT-002495 SR-TSV-002578 In short, ADSI is provided in three different "levels" of service: Level 1: Calling name and number after the first ring. Level 2: Calling name and number with call waiting. Level 3: A telephone with a display screen. (The "D" in ADSI.) Remember, originally Caller ID was just the phone number of who was calling, displayed after the first ring. Then, the service was improved to show both the number AND the name of the incoming caller. ADSI Level 1 is just that service, and it displays the incoming number and name after the first incoming ring. ADSI Level 2 delivers the calling number and name during call waiting by sending a short, low level sound called CAS tone, which the person on the receiving end WILL hear for a tiny fraction of a second, but it's not obnoxious. The CAS tone alerts the ADSI Level 2 phone to open the receive path to the user's earpiece, then the phone accepts a short burst of Bell 202-type modem info. The reason that this "obsolete" modem type was used is simple -- it requires none of the tedious "training time" that modern Trellis-encoded modems must have to handshake. The entire interruption in the listening path is only about a third of a second, then the incoming call number and name are displayed. If the receiving party has Caller ID with call waiting enabled on their phone line, but the phone they currently are talking on is NOT an ADSI phone, they will hear the CAS tone, but when the CO doesn't get the proper response back from the phone, it will NOT send the burst of modem tone with information. The proper response is a DTMF digit, that is how ADSI phones talk back to the CO or an ADSI server not owned by the telco. By the way, if two users are off-hook on the line, and only one is ADSI Level 2 compliant, when a CAS tone comes in, there will be no Caller ID on call waiting, as an ADSI Level 2 device must momentarily hang up, and check the line voltage to see if another phone is off-hook before going back off-hook and acknowledging the CAS tone. This is to prevent annoying bursts of modem tone in POTS phone users' ears. (I'm not sure what happens if BOTH phones are ADSI Level 2 -- if the timing requirements are tight enough for when they briefly hang up and check, they wouldn't see each other, and BOTH would go back off-hook and acknowledge the CAS tone. I don't have time to research it right now. Perhaps someone from Bellcore could comment, if they know ...) ADSI Level 3 came about because Bellcore did a study to determine how to sell more features on a telephone line, such as call waiting, or call forwarding. (The RBOCs like to sell these extra features as they are revenue above the standard line charge, and quite profitable.) The study concluded that many people didn't buy extra features because they didn't want to fool with code sequences to enable/disable features, such as *69. Bellcore's solution was ADSI Level 3. These phones have a screen that must be 20 characters across by 6 rows, and can be 40 characters across by more rows. There are from four to six "softkeys." Menu trees of softkeys can be downloaded to an ADSI phone, and stored in memory as a "script." The user gets plain English displays (or the language of your choice), and can press softkeys to activate telco features, or even order new ones directly from the phone without talking to a customer representative! Some of the RBOCs have also expressed interest in using the ADSI Level 3 phones for electronic white and yellow pages, Bell Atlantic comes to mind. Please note that an ADSI Level 3 session is also initiated from a a privately-owned ADSI server by a brief CAS tone. (Things work differently between the ADSI phone and the CO itself to change calling features.) The actual modem communication is always ONE-WAY, from the CO or privately-owned ADSI server TO the ADSI phone. This is because most information will be sent TO the phone in real life, the phone merely needs to respond with brief sequences of DTMF tones to indicate what softkeys the user has pressed. The user won't hear any of this, the receive and transmit paths are opened during ADSI Level 3 communication. Also remember that the far-end of the call will NEVER be a human listener, it will either be the CO, or a private ADSI server owned by a business. If there is an "achilles heel" to ADSI, this is it ... it can take up to two minutes to download a maximum-length, complicated script to an ADSI phone. An ADSI-compliant phone must have enough memory to hold at least four different scripts, so if one calls the same ADSI servers on a regular basis, this might not be a problem. Also, a smart programmer will probably only download short pieces of script to a phone, and then, while the user is reading the new options, they can download a bit more. The REAL attraction of ADSI is that ANYONE can have their own ADSI server! After all, it's designed to work on analog lines. In a couple of years, a screen phone will be used to call the local video store, scroll through the new releases, and even reserve one for later pickup. Or, perhaps one could call Domino's, order a pizza and toppings. Just imagine calling a business, and instead of getting the tedious voice mail prompts telling you to press *1 to do something, you get a text screen that lets you scroll though a directory of employees and select who you want! The high end ADSI phones that I have tested even have things like pull-out QWERTY keyboards for data entry, PCMCIA Type I slots, "smart card" slots, and magnetic strip card readers! Bellcore deserves praise for this well thought out service, laid out in several Bellcore standards. Another smart move on their part is that they didn't bother submitting the standard to an international standards body to try to get it adopted. (We all know how long that takes.) Instead, they have been visiting the PTTs of dozens of countries, and trying to convince them to sign on to the ADSI standard as defined by Bellcore. Several European nations have expressed interest already, as have Pacific Rim nations, including China. ADSI is being field-trialed by a few RBOCS right now, including Ameritech in Chicago. Ameritech is selling high-end Philips P-100 ADSI screen phones at cost for only $200 each, and primarily marketing it for enhanced banking features from your home, along with the ability to easily order/change custom calling features. It is estimated that there will be between 5 and 15 million ADSI Level 3 screen phones in North America by 1998, and I suspect the higher number is more accurate. Once you've tried one, you don't want to give it up! It is my opinion that ADSI, along with V.34 modems giving true 115 kbps data throughput (via V.42bis compression), could be an ISDN BRI "killer" one-two punch. ISDN is STILL not ubiquitous, the local telcos don't understand it and don't sell or market it effectively, and it will NEVER be offered in the boondocks where I live. (Mayo, Kentucky) In closing, perhaps the Editor will permit a small plug for my employer. TestMark Labs is currently the ONLY alternative to Bellcore itself, if you want your ADSI product tested for compliance to the full Bellcore requirements.

Bonjour, A new product is born today on the France Telecom catalogue: the "Teletel Micro." It's a transparent access for micro-computers connection between 300 and 14,400 baud on a single phone line (V22, V22bis, V32, V32bis with MNP4 and V42, and perhaps V34 [=28,800 baud]). All the hosts will be connected to Transpac and available all over France. Five numbers are already available for first time tests and evaluations: - 36011414: 0.59 FF/min (0 FF for the host); - 36011616: 1.27 FF/min (33.37 FF/hour for the host); - 36011717: 2.19 FF/min (75.28 FF/hour for the host); - 36012828: 5.48 FF/min (226.31 FF/hour for the host); - 36012929: 9.29 FF/min (402.36 FF/hour for the host). The forwarding of a service on another service will be only possible on same level billing services. France Telecom look at some companies able to give new ideas and/or realisations on this Teletel Micro. The contact person is Mr. Gerard Monin (phone: +33 1 44447299, fax: +33 1 44447831).

I have been following the news accounts and the threads here regarding the suggestion that Chicago area telephone users dial 11 digits on all calls. First of all, I think this idea is absolutely nuts. It seemed perfectly logical to me that Ameritech was introducing 630 as an overlay code for cellular, pagers and other wireless services. That way, one could tell by the number who/what they were calling. It would also be quite simple as follows: 630 to 630 - dial seven digits, 312 to 312 - dial seven digits, 708 to 708 - dial seven digits, anything else, do the 1-plus NPA thing. Then we get all this crap from these other companies complaining about the impact it will supposedly have on their customers, and how Ameritech will take up all the "good" numbers, etc., etc. First of all, my decision to buy a cellular telephone or pager or whatever service would be based on a NEED for, the PRICE of and the QUALITY of the actual device/service -- not the NUMBER that it will be assigned. Who started this concept of "good" numbers anyway? I order whatever telephone service, the clerk gives me the number, and I'm on my way. Am I the only one who doesn't care about the number assignment? I am basically a regular POTS customer who doesn't yet have a need for these companies' services. However, after reading about the dial-11-digit idea, I can't help the feeling of being manipulated by a bunch of startup companies (most of whom probably won't even exist five to ten years from now) by having to dial 11 digits to call my upstairs neighbor. If these issues are such a problem, I think it's time for Bellcore to devise a new nationwide numbering plan that will address all of these problems.

Callers from the UK are told that the number "has not been recognised" and when I asked British Telecom why this is so, they insisted that the numbers do not even exist. Pressed on this point, BT contacted AT&T who (initially) said the same thing but later had to admit that the numbers do exist, and that they STILL had not "officially" told BT about them -- and as a result BT had not put the necessary data about these numbers into the international access switches in London. It seems BT will be discussing this with AT&T, MCI and Sprint later today, and we just might be able to call you later this week. But until then, UK customers simply can't call US 500 numbers. And when we DO get access, we'll all remember the time difference before we make that call, right?

PAT] ------------------------------ Subject: 500 Service Comments From: Jeff_Buckingham%CallAmerica@emailusa.com (BUCKINGHAM, JEFF) Date: 08 Feb 95 11:59:55 EST I continue to be amazed at people's fascination with 500 numbers. Why is everyone putting up with so many problems just to receive a phone call? The irony to me is that the type of number does not have anything to do with the service that it's pointed to. I have a virtual number service (MyLine) with a local DID number and an 800 number. The 800 number works from anywhere in the US and Canada, from all hotels, payphones, PBX's, etc. The local number works locally and from international locations. I have a locator service that works today, without any problems. I know that AT&T sets things up in very strange ways (PIN numbers and AT&T recordings) but there are several virtual number providers out there today providing service that works on 800 and DID. I may point a 500 number (I have the 545 prefix reserved) to my virtual number if they ever work all the problems out but at least people will be able to reach me for the immediate future. All I am suggesting is that we stop the insanity and use the numbers we want to point to the services that we want. Jeff Buckingham jbucking@callamerica.com 805-545-5100 fax 805-541-7007 [TELECOM Digest Editor's Note: 'My Line' is a very good service. I have mentioned it before here, but newer readers may not know about it. In the past, one complaint about 800 numbers was that they could not easily be forwarded from one location to another throughout a busy day. None of the big three thought it was worth doing. Then Cable & Wireless came along with forwardable 800 service, but you had to pay an extra fee each month if you wanted the ability to automatically switch destinations. Enter 'My Line': Your own personal 800 number, not one of the gimmicks like MCI where you dial a number in common to everyone and enter a PIN. Persons calling your 800 number here a recording in your voice saying something like 'Hi, this is Pat ... please stand by while your call is transferred to me.' The switch then outdials the call to wherever you have told it you will be. Callers can enter a two digit 'override code' (if you told them about it and what code to enter) and this will force the call to be transferred to your 'priority' number instead of your 'normal' call forwarding number. You can toggle between 'call forwarding' and 'number referral'. In the latter case, instead of actually outdialing the call to you, the switch announces that 'calls are being taken at XXX-XXX-XXXX.' Priority calls still get outdialed directly to you of course, provided the caller entered the customer-defineable priority code. Voicemail is part of the package when you fail to answer; the switch withdraws the outdialed call and puts it in voicemail instead. 'My Line' also offers callback service for international calls, along with 'Wake Up Service'. You tell it when to call and wake you each morning. You use these additional features by entering your PIN during the initial recorded announcement. When it starts talking ("Hi, this is Pat, please hold, etc") you punch in your passcode right over the announcement; it switches to maintainence mode with the prompt, "My Line is ready". You change your call forwarding, listen to voicemail, etc. Best of all is the pricing. 'My Line' costs about the same as the plain vanilla 800 service you get from the Big Three, but they don't offer all the bells and whistles. Really, I don't understand why anyone these days would subscribe to 800 service from the Big Three when you can get so many extras from smaller carriers like My Line. This is the same company which offers 'Call America' 800 service, also discussed here in the past. I think John Levine and a few of you subscribe to that one; I do also. (Yes, I have two 800 numbers, two 700 numbers, my new 500 number, and three 708 numbers. That's not counting my pager; also a 708 number.) Anyway, please send off email to Jeff Buckingham, or call or fax. He'll send you complete details on 'My Line'. I've used this service for about a year now and am very pleased with it. You'll like it also. Here is his .signature again: jbucking@callamerica.com 805-545-5100 fax 805-541-7007 Whenever I run messages about My Line -- and I am quite impressed with the service -- I always get a message within a day or two from Arch Telecom telling about their version of the same thing. I imagine they will write again, and if so, I'll tell you about that one also.

Please try again later." (paraphrased, but you get the point) That's how my calls to both numbers were answered Monday afternoon around 1pm Eastern. I tried through several carriers, and even used one of my company's tie lines that dials out from 908 instead of 617. Calls to other points in Alabama (well, at least to 334-479) completed properly. Later in the day, calls were again being completed properly to Alabama DA. So ... anyone know what happened? By the way, my company's internal phone system does not yet recognize 334, or for that matter 360 or 630. The "real" NYNEX phone lines at work and at home are functioning correctly now. Scott Fybush - fybush@world.std.com [TELECOM Digest Editor's Note: Does anyone know what happened? Yes, I know what happened: ahem! Due to a high volume of calls, telco was unable to complete your call. The recording was rather self-explanatory wasn't it? It is another way of saying 'all circuits are busy now; please try your call again later.' At the time you called, DA was probably swamped with calls coming out their ears and other orifices. It happens, especially if their computer was down and they were doing manual lookups on microfilm or from books. They probably had every operator, clerk, typist, supervisor and secretary at their disposal taking calls and they were still getting buried alive. Calls to other points completed properly because other points were not swamped with calls waiting in a queue for an answer. You get caught up in that rush here in 312/708 occassionally also; but unless it is really severe they don't tell you to call back another time; they just hold you in a queue with an endlessly repeating message that, ' ... all positions are busy; please wait, an operator will be with you shortly ...'. They have really cut back on help answering calls to Repair; here in Chicago it is totally automated now. When you dial 611 you do *not* get connected at all to a live person unless you specifically bail out at one of the prompts. You punch the buttons to tell them the number you are calling from, and you punch the buttons to answer multiple choice questions about what is wrong with your service. I'd say you just hit them on a bad day in Alabama, or at a bad time.

'92), I viewed a videoconference by Kent Foster (a senior executive of GTE) sent via scrambled satellite broadcast to all employees. The topic of this discussion was why GTE was laying off yet more employees even though it had shown record profits the previous year. For the last few years, GTE had been consolidating on providing local phone service, and selling off other branches that weren't directly related, such as GTE Sylvania, and, thank goodness, GTE TestMark Laboratories. However, Kent actually admitted that for each $1.00 of local service that GTE sold, it cost them $1.28! The only reason GTE was profitable was the subscriber line charge for long distance access, plus the lucrative intra-LATA long distance market! Since these two sources of revenue are definitely doomed, GTE had to continue laying off employees so they could become cost-competitive in the local service area, their chosen area of competition. He actually went on to discuss scenarios where local competition was allowed, e.g., cable companies providing local phone service, along with "cream-skimmers" putting fiber rings to steal away large businesses in the main cities where GTE did business. If 40% of GTE's business was lost in those prime areas, the company might actually collapse due to insufficient revenues to service the huge long-term debt all telcos incur because of CO and outside plant purchases! It is a fact of life that for the last century, the various state PUCs and the FCC have treated local service as a RIGHT of citizens, and they kept local service rates artificially low so widows and orphans could afford phone service. According to Kent Foster, GTE would almost have to double local service basic rates to make a decent profit margin on the service, but the PUCs would never allow it. So, we have Catch-22. The FCC doesn't want the cost of local service to rise, but they are allowing intra-LATA long distance competition now, and the long distance providers are pressuring GTE and the RBOCs to lower or eliminate the long distance access charge. (Don't forget, AT&T recently bought a huge cellular company, which is definitely one way to bypass long distance access charges! And, MCI announced a 20 billion dollar plan to put in their own local service options in their twenty-largest markets, another "cream-skimming" operation!) If the FCC doesn't acknowledge reality, we might end up with the cost of local phone service suddenly jumping to impossible prices in the rural areas, while dropping slightly in the large cities. This scenario is made more believable by the fact that GTE stock has basically been a non-performer for the last few years, in spite of new record profits each and every year! The investors obviously think they know what the future holds for GTE and the RBOCs!

My clients primarily, Fortune 500 and governments, typically utilize DS1, leased fiber from the LEC, or CAPs to avoid these charges. Another way costs have been increased this that the SPF is based on the *cost* of providing switches. Since most of these were installed under *rate based* regulation, the LEC had every reason to oversize the switch and to *gold plate* the switch as well as the local trans- mission facilities. It is correct that much of the cost for long distance is due to SPF. But this begs the question as to why the SPF ratios were set the way they were. Large and medium size business provide the majority of LD revenues in the US. Residential and small businesses account for the bulk of the lines and voters. From a political and regulatory perspective it made and still makes sense to have business customers, particularly large business customers, subsidize small business and residential customers. The key question in the long run is whether residential and small business customers will accept higher rates or will they turn to the political process to reverse the current trend to increased competition for LD access and ultimately for local service.

I believe what Jack was saying was that BILLING ACCOUNTS should have a PIN, to prevent unauthorized individuals from changing service. Apparently what happened in this case is the bad guy called the telco claiming to be one of his competitors. He ordered the remote call forwarding service on their lines, then used it to forward their lines to his number. Note that since HE (the bad guy) ordered the service, HE got to supply the PIN. Another simple way for telco to prevent this sort of thing would be to call back the customer requesting the change, and ask him to verify it.

The first generation of "hybrid" digital phones, which appeared in the early 1980s on digital PBXs were almost all six wires, with the outermost pair being DC power to the phone, the next pair being digital control for signalling, and the innermost pair being analog voice, which sometimes also carried DTMF tones generated by the phone. Four wire digital phones came a little later in the eighties, and they typically "simplexed" the DC power onto the data and analog voice pairs. "Modern" digital phones are truly digital, and they send digital packets on the single pair, which also feeds DC power to the phone. One unforeseen side effect of this final digital PBX phone design is that it is a modem "killer." People working in offices with digital PBX phones are often unaware that these phones aren't POTS, so they will unplug their proprietary digital phone and plug in their modem (or fax machine). Many brands of digital PBXs supply 300 mA or more to their digital phones, and this will burn up the front end of a POTS modem or fax machine. (Sometimes it even sets the device on fire!) Since Sergei's Memorex phones are six-wire, this suggests they are fairly old, and probably not manufactured anymore. I recommend that he keep reading TELECOM Digest for a week or two, there are a few resellers of old phone equipment who put ads in every so often.

Chicago is hardly a unique case. The first overlay NPA (917) went into effect several years ago in New York City, where it overlays 212 and 718. True, 917 was originally reserved just for wireless and (I think) fax and data lines, but I doubt that convention will survive another fill-up of 212. With a bunch of new overlay NPAs coming soon (Houston, Miami, Los Angeles and possibly Atlanta), it will be interesting to see what kinds of dialing plans emerge. > In the rest of North America, we are having to dial the area code for > all long distance calls within the area code, so that the system can > handle the new area codes that look like prefixes. This is not true either. Actually, it's true for *most* of the rest of the NANP, but there are a handful of states (NY and IL among them) which instead went with a 7D dialing plan for intra-NPA long distance.

After that it is 25% off all calls if the monthly bill is over $10, 30% if over $50. The 50% discount will only be to other MCI customers in your Friends & Family list. This is off the standard rates (generally just slightly less than AT&T's). It makes more sense than any other plan they have except for intralata calls in Texas.

(Pretty Amazing New Stuff.) ADSI is state-of-the-art technology -- for 1975. However, it is 1995, and Bellcore's low speed, asymmetrical protocol doesn't meet today's expectations for a multimedia information terminal. A little background: ADSI provides 1200 baud signalling to the CPE and a DTMF backchannel. So, ADSI is really slow sending info to the user, and the user can only signal back in DTMF. This is inherently limiting, as you might imagine. ADSI also defines presentation capabilities which allow the server to write text and options on the CPE screen. However, this capability is text-only. So, here we are on the brink of the Infobahn with cable companies and on-line services promising users a rich multimedia world replete with full motion video and CD quality sound and here's Bellcore offering 1200 baud text only services. OK, maybe the Infobahn stuff is a little way out, but ADSI adoption hasn't exactly been earth-shattering. By the time there is any appreciable penetration of ADSI phones (if ever), people will have truly state-of-the-art capabilities in their TVs and PCs. Meanwhile, the phones, phone companies, and telecom folks (us) will look dumb showing off ADSI stuff. Furthermore, we would then have a backward compatibility issue with these installed devices as we tried to move into some new technology. Therefore, we in the telecom industry should be pushing for a more modern voice/data solution than ADSI, one which will carry us into the next century. For instance, the Radish VoiceView protocol is a fully symmetrical switched voice/data solution which allows data (anything, not just text) to be carried at much higher speeds; the protocol also allows negotiation for fax (unlike ADSI). We should see VoiceView modems appearing later this year. Plus, digital simultaneous voice/data (DSVD) standards are coming soon (i.e. next year) which will allow high speed data connections plus voice on the same analog line. Finally, I'm not sure how v.34 and ADSI finish off ISDN. If I'm running v.34, I can't talk on the line. ADSI makes no provision for interrupting a data call with voice or a voice call with v.34 data, so these two things are unrelated. (Besides, I'd like to meet the person who gets 115kbps reliably over real phone lines using v.34.) (Other random thoughts: when the head of any RBOC talks about the Information Superhighway, none of them has ever mentioned ADSI as a key technology in making our future happen. If they don't believe in it, why should we? Something else to keep in mind: who will be the torch bearer for ADSI? Last I checked, Bellcore was for sale. Given the uncertainty of their future, I wouldn't count on them to propagate any standards.) Thus, ADSI is hardly new (technology wise) and not very amazing. Just say 'no' to ADSI.

On the switches I have worked on, I designate which DS1s the switch should use for timing. Check where your PBX is receiving timing. Assuming your switch is clocking off of the DS1 like it should be, a second problem can come from having the clocking DS1 on SONET facilities. We have found that SONET DS1s have significant jitter, and can not be used for timing. We have gone so far as to require special facilities from the LEC to avoid SONET routing. With the T1 on SONET, your PBX may be unable to clock properly. Ask your telephone company how the T-1 is routed to the central office. You will need to convince the LEC to keep at least one DS1 off of SONET facilities, and program your PBX to use that DS1 for timing. I hope this will give you a few more ideas.

One other reason for the 10 (11) digit dialing is that the NPA and NXX in an area may be the same now that '0' and '1' are no longer required to be the middle digit of the NPA. So far it has been avoided mostly, but in the future it will not. If only seven digit dialing were used in this case, there is the possiblility that the switch will construe it as a misdialed number if only seven digits are dialed if it thinks the first three digits are an NPA. Granted the software can be designed to get around this, but well ... Jill C. Arnson Omnipoint Corporation Colorado Springs, Co (but Denver's where I hang my hat) jilla@csn.org [TELECOM Digest Editor's Note: Its not that the software can be designed around this -- it HAS been designed. Ever hear of timeouts? If you dial something which can be interpreted in a couple different ways depending on what digits follow, if any, the central office will sit there a few seconds following your last key press waiting for more. Lacking any further entry on your end, translation is started based on the context of what you did enter. For instance, you dial just zero for the operator. It is going to sit there a few more seconds waiting to see if you plan to continue dialing with 011, or 01, or 00, or 0+area code and number, all of which are valid combinations. To avoid timeouts and waiting, try dialing 0#. That 'pound sign' on the end functions as a carriage return. It means the dialing string is finished. Ditto with credit card calls to the number associated with the card; you only need to enter the four digits of the PIN. But the computer does not know what you are dialing, so it will sit there and wait to see if more digits are following. Terminate the PIN with # and watch how fast your call is processed. Anytime the number of digits to be entered is variable depending on context, use the # on the end to speed up the process in the same way you were told to do with international calls. Note that when you dial a seven or eleven digit number, adding # at the end does absolutely nothing to speed up the connection.

I take great pride in offering our guests the luxury of trouble-free communications away from home. I don't want to block these calls, but I'd like to make sure I have all the facts straight regarding who pays for the calls. If I understand correctly, I assume that if I were to call our Esteemed Moderator's 1-500-number at 4am I'd be greeted with a grumble and a click. :) From there I assume that a charge would appear on my telco bill by AT&T for a one minute call from VA to Chicago. At what rate am I being charged? (i.e. Basic Rate, Calling Card, Flat, etc. ?) Do I lose the benefit of any calling plans I subscribe to? Having been burned to some extent by each new calling scheme that's come down the pike in the last ten years, I'm a bit cautious, as I'm sure you understand, but I deplore the thought of a business traveller calling my (clueless) desk staff complaining that their 500 number can't be completed and the clerk responding with such infinite wisdom as "Huh?". (Although from what I've seen, some of AT&T's staff could fill those shoes!) Basically, I want to be able to provide the service without being taken to the cleaners. I presently block NO numbers going out of my PBX's. My CO provides blocking for 900 numbers and those nasty 800 pay-per-call deceptions. I then bill all remaining 1+ calls at a fixed markup from our actual fixed rate. But, as I command a .0935 flat rate from our carrier, (who is NOT AT&T) I'm afraid that I'll book a loss on 1-500 calls if I'm billed at calling card rates by AT&T! On a self-preservation note, I'd like to make it clear to anyone planning a pity party for me due to the widespread raping and pilfirage undertaken by most hotels with regard to telephone charges, I absolutely do not and will not gouge my guests to use my telephones. It has become quite commonplace in this industry to take whatever steps are necessary to recoup lost revenue due to increased competition and lower occupancy rates by increasing tele- phone charges. Every chain franchisor/operator out there has a national account with one LD carrier or another and NONE are paying more than .105/ minute for direct dialed, interstate calls. Flat rate, any time, anywhere. Most even have up to 50% off international calls. Yet, if you make a 1+ call from any one of thier rooms, you can expect to pay between $1 and $3 _per minute_ (!) for that call. So, as a result, most travellers are now using calling cards exclusively when on the road. Well, that really pissed 'em off. In retaliation, the AOS was born. These cut-throat upstarts intercept calling card traffic flowing out of hotels, lock 'em up in a Mitel SMT-1 Dialer box and shoot 'em through someone's basement in Idaho, re-route through who-knows where, mark up the charges to an astronomical rate, tack on some profit to kick back to the hotel, pause a few months for effect, then send billing data to the poor victim's telco. Three months after a trip, John Q. Customer has a $6 charge on his bill for a one minute call placed from a number he doesn't recognize, but barely remembers visiting the city. A call to the telco provides the number of the offending carrier. Another call puts you in direct conversation with a real live Auto Attendant with a menu longer than Denny's. If (and I stress IF) you reach a human (or at least their interpetation of such) you can expect all the warmth and understanding of an iceberg. Oh, dear, I'm ranting. Sorry. But you get my point. After all, I guess someone has to pay for those fresh lox and bagels on the complimentary (ha) continental breakfast spread. My point is that I don't condone these practices. The phones in my rooms are but another amenity I provide for my guests comfort just the same as clean sheets and hot water. Next thing you know they'll be putting water meters on each room ... (Stop him before he rants again!) At any rate, I'd appreciate billing procedures and rates for 1-500 service. I'm assuming that 0-500 numbers are always billed to either the callee or a calling card. Thanks for listening. [TELECOM Digest Editor's Note: Don't make too many assumptions. As 'they' say, when you assume something, it makes an ass out of 'u' and 'me'. One option under the 0-500 menu is 'to charge this call to the number you are calling from, press 1'. Now I think you can probably work around that with billed number screening; that is, the feature offered by most local telcos which forbids collect and third number billing. I am not sure. I think if you have billed number screening, then billing option 1 under 0-500 is not given; or it may be given but when the caller chooses it a response comes back that 'charges cannot be billed to this phone'. You will want to clarify this with your local telco. It is true in most cases that 0-500 works like any other zero plus call; you need to then use a calling card or call 'collect' (which in this case is done with a PIN). There is no option for third number billing. But make sure your telco can block that 'bill the call to the number you are calling from' option. This is not something to bother AT&T with; your local telco does all the billing. I know when using payphones, the option 'bill to the phone you are using' is not even given, so obviously they can tell the difference. On calls dialed 1-500 and billed direct (or dialed 0-500 if the guest slips it to you by pressing '1' in response to 'bill this call to the number you are calling from') you will be billed by AT&T at the rate of 25 cents per minute during peak and 15 cents per minute at night and on weekends/holidays. Peak is 8am to 5pm your time, Monday through Friday. You *will* be billed by AT&T on your local telco bill (in most places) and you will *not* be billed by whoever is your established carrier, nor at that carrier's rates. You will receive none of the benefits your carrier gives for discounts, etc. If you happen to be an AT&T customer, then the charges for 1-500 calls are counted toward any discounts for volume usage given by AT&T. It does not matter where in the USA you are, the rate is 25/15 cents per minute, even if you are next door. That much should be easy enough to program for. The catch is, if calls are being forwarded outside the USA, *then international rates apply*, billed to *whoever places the call*. In other words, you can't absolutely count on the 25/15 rate. Most always it will be, of course, and if the owner has his 500 number forwarded internationally then the caller will get a warning from AT&T 'this call is going to an international point and will be billed at international rates', but can you count on your guest in the hotel (or the user on your PBX or whatever) to tell you about this? You will get the charges for the international call. You will eat the charges for the international call unless you have recourse to the person who placed the call. So be careful of 1-500. You will almost always see the 25/15 per minute rate *but not always*. I would say since there is no easy way to discern whether a 500 call is going to terminate domestically or internationally, other than the verbal warning given to the caller by AT&T as the call is being set up, you'd be wise to set your rates accordingly. Mark up that 25/15 to something you are comfortable with for profit, assume (there we go again!) that for the immediate future 500 is mostly going to terminate in this country (at least until it gets very popular, if it ever does) and accept your occassional (hopefully very rare) losses on 500's which have been forwarded to the South Pole or wherever. There are intra-state exceptions to the 25/15 pricing; most states have gone along with it; check to see if your state has slightly different rates for in-state calls. Note to PBX admins: if you require your users to give a PIN as part of their long distance call, or you can identify the user based on the extension from which the call was placed, you have no problems. Just pass along the charges accordingly; mostly 25/15, occassionally something else. Now on 0-500 as noted above, if you have 'bill to this number' as an option removed, then the choices are bill to the caller's own credit card (not your problem) or call collect using a PIN (again, not your problem where the call terminates.) And yes Mr. Kipps, hotels have lately had the attitude that every single item in the house must be a profit center. I am surprised they don't charge guests to ride the elevator ... there is a few square feet of floor space not turning a profit! Many years ago when my friend Mrs. Brown was the resident manager of a hotel in Chicago, she explained about phone service. She said the switchboard never makes a profit; " ...in fact we lose a little on it, but you have to provide it ..." It was understood that it was a courtesy for guests. You made your money renting rooms, not selling phone service. She told me a funny story: she said she had an agreement with 'Kenwood Bell' (she was on the Chicago-Kenwood CO of Illinois Bell) which was that she did not sell phone service and they do not have rooms for rent ... . Hey, if business is that bad, start renting rooms by the hour ... oh, I guess you don't want that kind of a 'house' either.

PAT] So now that you've been though it Pat, do you mind telling us the possible options/features of 500 service? It sounds like you can set up a hunt group, which I was not aware of. Will it do a hunt on no answer? And if you don't mind, how much is it (i.e. for different levels of options)? Marc Randolph mrand@tamu.edu -or- mar6019@tamu.edu PGP keyID: 4C95994D ...!{uunet,gatech}!tamu.edu!mrand [TELECOM Digest Editor's Note: You dial 0-500-your number and when requested, enter your master pin. You then get a menu which allows you to modify your 'reach list', turn on/off override (of your reach list), place a call to your home or override number, check voicemail, and do a few other things. In the reach list, you can give up to three numbers to try and reach you at. When someone calls your 500 number, it starts at the top of the list, working its way down until some one of the phones on the list is answered or it reaches the bottom of the list. For instance, your reach list can have your home number (abbreviated H# if desired when you enter it), your cellular number (abbreviated C# if desired) and perhaps your work number or voicemail. It starts at the top of the reach list and rings that phone the number of times you designate (default is four rings, but you can set it as desired). If no answer or busy, a voice comes on the line and says, "please hold, we will try to reach your party at another number." It then tries the second number on the list, and if necessary this repeats and the third number is attempted. You can have as many 500 calls simultaenously as you have terminating facilities. In other words if you have two lines at home set up in hunt, then you can have two 500 calls. If both those lines are busy a third 500 call would look on the reach list for the next place to try. I don't think there is any limit to the number of 500 calls that can be aimed at you at any one time other than whatever number of calls you (and the various places on your reach list) can handle at one time. You might have your 500 number point to your PBX (as the first number on your reach list) during the day. At night when your PBX does not answer, calls would go to the second number on your reach list, which is your office in another state which is open all night, etc. If your PBX can handle 20 incoming calls, then you can have 20 incoming 500 calls if desired. Maybe the third number on your reach list is someone who takes calls on weekends. By calling in with your master pin, you modify the reach list as desired anytime. If you want only one number on your reach list which you call in and change throughout the day as you travel around, that's okay also. Just scratch the other two. You can have up to three to be attempted if desired. If you are going to be at one place on a temporary basis and don't want to change your reach list, then a provision is made called 'override the reach list'. You enter a single number to *always* be used until you turn off this feature and tell it to go back to using the reach list again. So it truly can be a national number just like 800, but with more flexibility because you can require the caller to pay for it unless he has a pin, and you are not tied down to any one location as you are with many old-fashioned 800 numbers, although companies like 'My Line' and Arch Telecom have eliminated that problem. You can use your 500 number to make outcalls also and not have to bother with a calling card or calling collect. At the present time, you can only call your home number (H#) or your override number, but that will be changed later this year so you can call anywhere. Now with 'My Line' and Arch Telecom, you can presently use your 800 number for outcalls to anywhere. AT&T says 500 will eventually have that also. If desired, you can have what is known as 'Final Stop' with 500. This has to be either AT&T provided voicemail or voicemail from the vendor of your choosing. If all the numbers on your reach list are busy or do not answer, then calls go automatically to 'Final Stop'. If you wish, you can override the reach list and send calls to 'Final Stop' directly. If desired, call screening is also available. You can toggle options which allow only calls made with pin numbers to reach you, sending all other calls to Final Stop (voicemail). There is an option where calls deemed 'urgent' can get through the call screening while all other calls go to voicemail. You get recorded help at any time by pressing *H, and *0 will transfer you to the business office at any time for further assistance. Prices for the different options vary, and I do not have them all here. Right now everything is one dollar per month through April. For more information call them at 1-800-982-8480.

It's really annoying ^^^^^^^^^^^^^^^^^^^^ I'll second you on that (is anyone from Motorola listening?). My phone has tons of controllable options, but not how many times or loud to make that damned beep. One thing that's interesting is that when I'm using the phone, it only beeps about four or five times (maybe one to two minutes) before the battery drains and the phone shuts off. When I'm not using the phone, it'll beep about once every minute for at least 15 minutes. My instructions for my xt-pak ni-cad batteries say to maintain long lifetime, I should discharge them fully before recharging (all the time, not just the first five times), so I've found I must stuff the phone under the couch cushions overnight so it won't wake me up.

There appears to be a problem between the first and second repeaters, which would put it approximately 60 Km off the coast of Oregon. In addition to Asian traffic, the NPC has a spur to Alaska, and all traffic is currently using satellite re-route.

Instead of the PBX going away, see it as yet another server on the LAN. I work with NEC systems involving about 50 trunks by 100 to 200 lines, (a small switch) It takes a lot of power to drive this thing, making analog sets ring, driving digital sets etc. I am also sure that the bandwidth on a LAN will ever increase to be able to handle the increased voice traffic, just as the PC will become more stable -- not needing the three fingered salute from time to time. The reported weakness of the PBX, the closed system approach also was a a foundation of its strength, amazing durability. Today the PBX is augmented by the computer (integrated messaging, authorization code database, ACD) and that forms a network of distributed -- not dedicated, processing.

I'm not sure who was the first to do it, but the first cellular carrier to file a tariff providing free access was U S WEST NewVector Group.

The difference is that a bit is a binary digit (a single one or zero) while a baud is a signal-element-per-second. The signal elements sent by the modem each represent several bits (actually, with 28.8Kbps, it's a variable amount), thus with about 3200 baud and 9 bits per baud you get 28,800. This is a synchronous data rate, so async framing conversion data and data compression run on top of this 28.8Kbps pipe.

Actually, it would be 110 to 28,800 bits ber second. A V.34 28,800 modem can use one of 6 baud (or symbol) rates at a time: 2400, 2743, 2800, 3000, 3200, 3249 > The data is not sent at 28,800 bits per second, however. > Typically the modem will divide up the telephone line into six > or more channels, and run each channel at 2400 to 4800 bits per > second. By multiplexing six channels at 2400 baud, you get > 14,400 baud, etc. This is incorrect for V.34 (28,800) modems. A V.34 modem only uses a single "channel". During negotiation, the line is characterized by a process refered to as "line probing". Based on that information, one of the 6 symbol rates listed above is selected. To achieve multiple bits per baud, Trellis Coding is used. [stuff deleted... now discussing FAX] > There are two speeds for transmissions.

This 300 baud (which is also 300 bits per second in this case) modulation is the V.21 high channel. Several other pieces of information (such as machine capabilities, page width, etc) are also transfered in a protocol defined in T.30. > The sending machine then increases its speed and the transmission > takes place in the equivalent of "half duplex" mode, except that the > recipient machine typically acknowledges the end of each page and end > of transmission.

I recently saw a review of 28.8kbps modems in {InfoWorld}, and they saw true 4:1 bit compression on modems under "ideal" circumstances, i.e., very high- powered PCs, using V.34 modems with V.42bis compression on parallel ports, or on specially-buffered serial ports.

V.32bis is the modulation protocol spec for 14.4 kbaud; v.42 is the reliability spec; v.42bis is the compression standard; v.34 is the modulation protocol for 28.8 kbaud.

I think that the above isn't telling much of the story. The link between modems may be at 28,800 BPS, but the bytes are being transmitted as octets, synchronously. They are not 10 bit asynchronous bytes as they are between the PC and modem. Also, there are other things done between the two modems, such as error detection and correction, and compression. So what is going on between the PC and modem has little relationship to what the modems are doing on the link.

Such courtesy became "legal" in the Washington DC area (area codes 202,301,703) and along the 301/410 border in Maryland; in those places, local calls to another area code are published as NPA +7D (can omit the leading 1, but you may include it). Someone told me of having to use leading 1 on local call from Delaware County, PA (possibly 610-485) to Philadelphia.

Austin, TX Reply-To: mr@Tadpole.COM Voice Powered Technology has a phone (Tel-It Phone I believe) which holds 40 recorded names. Each name can have up to three numbers (home, work etc). It will replay the recorded name between rings if the number received via CID matches one of the stored numbers. The recorded numbers can be dialed using voice recognition also (fair accuracy, names are divided into two groups of 20 which you have to tell it by pushing a button, up to two speakers with seperate memories for the voice recognition ... this doesn't mean you can store 80 "names".) Also has an Name and number CID with a one line LCD Display and call timer, on-hook dialing (NOT a speakerphone! only mike is in the handset). A good value IMHO at $129.95. I bought two and a friend got one after seeing mine. Available through Sharper Image etc. Also available direct although I've found VPT diffficult to deal with directly (bad delivery times and they initially quoted a higher price when it came out, terrible order line people, customer support poor and excellant in two calls. I own a Voice Organizer also.) I wanted the phones for the CID recital function. Nits: -Display bezel makes reading the upper edge of the display very difficult at most angles; -When the voice recognition feature is used, it will replay the recorded entry it thinks you said before dialing (good), but if it's wrong you have to hang up and retry (bad!!!). I wish it would recognize a spoken "NO" and "guess again" the way the Voice Organizer does.

The lines leading from the campus to Southwestern Bell are analog and there is some question about what they connect to after leaving the campus. There are definitely no T1's between here and there.

In his response to what is a channel bank (Matthew P. Downs) wrote: > Not every one works on DLC's He is right. But, he seems to have chosen a narrow perspective on his answer because he referenced DLC's as though they were the only system with channel banks. Channel banks have been around since the 1930s under the name of carrier terminals. We started calling them banks in the early 60s when T type digital hardware began to be installed. Digital Loop Carriers (DLCs) come from many vendors and may use channel banks at the subscriber end (a.k.a. RT for Remote Terminal). At the central office or switch end, they may terminate in a channel bank (LT for Local Terminal) or be directly connected to a terminating card in the switch. Generally, a direct connect system is called an IDLC (Integrated Digital Loop Carrier). The switching folks often have never seen a channel bank on the subscriber (phone) side of the switch because so many SLCs (Subscriber Loop Carrier, of which DLCs are but one form) are directly connected. Even the interoffice (trunk) side can be integrated, so the use of individual channels in a bank of channels may seem strange to some of the newer folks in telecommunications. All SLCs are LINE or LOOP extension/multiplexing devices. The earliest ones were, of course, analog and I'm sure there are still some in use around the world. Most are now digital. The term slick came from the SLC abbreviation. Interesting to note the different terminology of our industry relative to interoffice and local loop carrier systems. I worked on short haul carrier systems for the phone company as a toll transmissionman from 1965 to 1981, and we always just called them carrier systems. The outside plant folks on their SLC systems called theirs pair gain systems. When I first heard that term I kept asking where the amplifiers were on the wire pairs which added the gain to the signal. Took a while to figure out what they meant was that using a multiplexing carrier system requires fewer pairs of wires than individual metallic circuits and thus they gained the use of more pairs in any particular cable by converting over to a carrier system. Duh! I was teaching a class on LAN/WAN interconnection issues last week and this very question came up. I'm always a little surprised at the very deep, but incredibly narrow, technical knowledge base of so many people in this industry. I know it is a natural result of the specialization necessary to hold a job these days, but it sure creates some challenges in installing and maintaining networks that could be better met by having a few more generalists around. Lots of LAN folks are beginning to stretch their nets and need a path out that appears to be technically slippery for them, or may be it just looks SLC from where they're standing.

Combee) Subject: Eleven-Digit Dialing For Local Calls Date: 9 Feb 1995 07:13:42 -0500 Organization: ROASF Atlanta Reply-To: combee@prism.gatech.edu Hello, TELECOM Digest readers. In reading the recent talk here about Chicago possibly requiring 11-digit dialing for all calls, I was wondering about current practice. Currently, here in Georgia, you dial seven digits to make a local call, but any long-distance, even intra-LATA is made with eleven digits. If you were to call a local number using the eleven digit sequence, would the call go through as a local call, or would billing be as a intra-LATA call? If I were to call across campus using 1-404-NNN-XXX instead of just NNN-XXXX, would I be billed for that call? Ben Combee combee@prism.gatech.edu http://www.gatech.edu/acm/combee.html [TELECOM Digest Editor's Note: I doubt the call would even complete, if things work the same there as here. In this area, if I dial 1-708 my call is intercepted with a recording saying 'when dialing a call within your area code, dial only the seven digits.' Most telcos I have heard of are the same way. They do not allow 1+AC within your local area. They do allow -- in fact require -- 0+AC within the local area when you wish to place a collect, credit card or third number billing call. Now assuming your telco is different and that it does allow 1+AC on local, same area calls, you probably will find that the local telco does as it pleases with the call anyway. For instance, although we can dial 1-xxx plus 1 plus AC and a local number, Ameritech does *not* hand the call off to the designated 10xxx if it is a call within the immediate area they are entitled to handle. An exception is calls to points more than 15 miles away (to us, that would be the 'C' or 'D' zone) dialed via 10288. That is allowed through an agreement betweeen Ameritech and AT&T. So although (if such dialing is allowed in your area) the call would go through, it would probably be your local telco transparently handling the call, and it would probably be billed like any other local call with the long distance carrier(s) not even seeing it.

I was wondering if any of them work for evening only or give you more time for evening calling. That seems like they only way they could even in the same ballpark as normal evening LD rates. Maybe a "unit" is different depending on when you call? Anyway, just looking for some information. Thanks, Philip Winston pwinston@hmc.edu http://www.cs.hmc.edu/people/pwinston [TELECOM Digest Editor's Note: They are a pretty lousy deal. Most charge fifty cents per minute, in one minute increments. That's not surprising, considering there are so many hands in the pot trying to cash in on them. Many/most pre-paid card are multi-level-marketing things; everyone wants a commission. For example, a couple years ago I experimented here with the Digest readers with a type of pre-paid card called 'Talk Ticket'. For two dollars, you got four minutes of time in increments of one minute each. I paid, I think, $1.45 per card and resold them for the published price of $2.00. Whoever I bought them from got them for about 85 cents each I believe. A unit is a unit is a unit; day or night, weekdays or Sundays; it does not matter. You could also, if desired, spend the four minutes on the extra features offered such as voicemail, news weather and sports, hot chat on a conference bridge, etc. Prepaid cards are promoted as a way to allow someone to use your telephone card a limited amount of time -- presumably for calls made to you -- without the worry of that person abusing your regular card. They are also promoted as a way to greatly reduce toll fraud, since if you lose the card or get shoulder-surfed at the train station all stand to lose is the remaining balance on that card. Those are good reasons, but the other side of the coin is you pay so much for them by comparison. I put prepaid phone cards in the same category as American Express or Traveler's Express Money Orders. You pay them money for the privilege of lending them money until you get around to cashing it in. Did you know American Express typically has a float of about two million dollars per day on their money orders? You want to let *me* borrow two million dollars just for the day? Just for a few hours? ... I'll happily take you up on the offer and return your two million with interest. So Amex and the other money order people *should* issue their money orders for free, for just the face value of the check. People are loaning them a lot of money; there should be no need to pay a fee in addition. Ditto with prepaid calling cards: The Big Three should sell them at steep reductions over the regular cost of a call since they are getting to use your money until some future time. If they sold for something like five to eight cents per minute, that would make them worthwhile. But they can't go that cheap because it costs that much to connect you via 800 with their switch, plus whatever they pay for the outcall. So, let's say they charge 20-22 cents per minute. That would still be sort of reasonable, but not the 50 cents or more per minute most of them sell for.

PAT] Atlanta will be ten digit in June of this year. The way I understand it, it is necessary for the discrimination of more than 9,999,999 (in theory) numbers. We can of course reduce that by two million, in numbers that start with 0 or 1. Basically, the '1' as a country code, is necessary to disting- uish long distance toll calls. Atlanta will be ten digit all local calling area -- almost a 100 mile radius fee zone I believe. Not imposing ten digit on your own area code would put great strain on the switching system, as prefix and area code would be dificult to distinguish. You could say, "well, if I only dial seven digits there is no area code.", but would you then like to wait 30 seconds for the system to make sure you were done? how else would it know you werent calling an area code equal to the prefix you dialed? Well, we could rule out all area codes as valid prefixes ... but that would really cut into valid numbers, at least eventually it would. '1' will still be needed for long distance, to signal that you need to be passed to the control of your LD co, and out of the local. This might not be needed if Ma Bell were still the only phone company, but which would you rather have ... Ma Bell, or '1'? Im sure the switch wont be 'easy' for some of the less gifted, but come on, its only three buttons, and most of us have speed dial. What if I wanted all internet ip's to be only two sets of three? :-) Now that that's off my chest ... Brian Klippel briank@netcom.com [TELECOM Digest Editor's Note: Not that I am saying your comparison is quite correct, but I would not mind having Ma Bell again. The competitors are fine also, but Ma Bell should have been left intact. I think Greene should have opened the door to competition, absolutely required that AT&T work fairly, at arm's length with all competitors regards interconnection and let it go at that, with a short speech saying something like this: "The telephone network in the United States is a carefully woven togther, highly sophisticated entity. It has taken a century to build. I am not going to allow you to rip it apart and move in, skimming the cream from a century of work by AT&T, its associates and employees. What I will do is permit you to compete fully with them. Build your own telephone exchanges, string your wires, develop your customer base, install instruments, convince AT&T's customers to sign up with you instead, operate a major research laboratory in the process, do it all -- local and long distance. Put together a national telecommunications company and convince the public yours is better. If you want to leave out a few parts here and there and people still think you have a better deal, then fine. I am requiring that AT&T, the Bell Companies and other independent telephone companies inter- connect their lines and exchanges with you. They are required to cooperate with you in the assignment of telephone numbers and area codes. When you come to their door seeking interconnection, they are required to promptly turn over sufficient cable and pairs to interconnect. They are not required to allow you to set up your shop inside theirs. You may build yours next door if you wish. They are required to do nothing but allow your customers to interconnect transparently with theirs and vice versa. You may contract with them if desired for directory and operator services and I require them to give you this on the same terms as they give it to their own companies and the independent telcos." Now that would have been true competition, and the American way. Instead, Greene nearly guts AT&T. What were they supposed to do, apologize for having been in business for a century, and deny all their accomplishments over that period of time just so MCI could make their money a little sooner? Regards needing a time out in the event of variable-length, variable- context phone numbers, what do you suppose the pound key (#) under the 9 is for? It is the carriage return, the indicator that the input string has been finished. Have numbers of any length or composition you want with the understanding that when you have finished entering the number you press #, and the switch goes to work on what it was given. If you put in seven or eleven digits now when the same is expected, the # does nothing. If you put in less than seven (when at least seven is needed) then it does nothing. But on variable length numbers such as pin versus full card number and on international calls, it works just fine to get rid of the time out. Why not develop that further and see how much more flexible our numbering system could be?

Does anyone know of a product like > this? Supposedly, as long as your cellphone has an ISN (electronic serial number) cellular providers can't block access to one number: 911, and you can dial that even if you're not currently subscribed to any cellular service. Naturally, cellular phone companies don't publicize this, as people would just buy cell phones and not subscribe to a service, just having it handy for emergency use. In California, 911 on a cell phone connects you to the California Highway Patrol. It can be very handy on the road, as the CHP will connect you to the Auto Club if you're a member and are having car trouble. It sure beats, and is safer, than going to a freeway callbox, that does the same. [TELECOM Digest Editor's Note: I don't think people would buy a cellphone for just that purpose. How many calls to 911 would they need to make to amortize or justify a two or three hundred dollar cellphone? You don't think without contracting for service the dealer is going to sell the phone for the cheap price do you? PAT] ------------------------------ From: zakezuke@coho.halcyon.com (Matthew J.

I've been told that unactivated cellular phones in the PNW region are able to dial 911, and 711 (cellular operator), unless the phone has been flagged as stolen. I've also been told that one can go though the cellular operator and place a collect/third party/credit card call.

Sysop: Apple Elite II -=- an Ogg-Net Hub BBS Home of GBBS/LLUCE support (909) 359-5338 12/24/14.4 V32/V42bis [TELECOM Digest Editor's Note: You are correct that residence and small business users have been shafted royally by divestiture and deregulation. Now there are some readers here who over the years have contended that all the technological advances of the past decade would never have happened had not AT&T been running scared from the new competition, and that is probably correct. But competition -- true competition -- does not mean you rip apart your competitor. Let us say I run a large general store. I sell everything there. One of the big hot selling items is on sale there and I use some of the profits from that to subsidize other areas of the store not doing as well. You come along and want to do a hit and run, quick and dirty sale on the profitable item. But you can't get people to come in your little store and look at that one item you sell because they are all roaming around over at my store. I am more than willing to have all the customers standing around idly in my store looking at stuff which does not make me much money -- even when they do buy it -- because I know they will eventually wander over to the other area in the store and look at the big ticket, hot selling stuff that I make my profit on. To you this is quite unfair and you complain that if the customers were not allowed to hang around in my store, they would come over to your store instead. So you demand I have to get rid of my department X and department Y, and futhermore you insist that I set my prices on the profitable items in such a way that you can still sell yours for less and make a profit yourself. When I reduce my prices, you have to reduce yours also and that puts you in kind of a bind. The forced divestiture of AT&T was a very immoral, unethical act by Judge Greene. Yes, I know, they signed a consent decree. Please don't start up on that one. If your head was on a chopping block and someone offered to let you 'voluntarily' sign a piece of paper instead, what would you do? Charles Brown, the Chairman of AT&T at the time of the divestiture said the *only* reason they signed off on it was because of the way it was draining the company's resources. I think they realized early on that a fair trial from Judge Greene was not going to happen, and that when the US Department of (In)Justice gets a bug of some kind, they will go on for years if neccessary. Thank goodness IBM did not cave in. I only wish AT&T had held out.

The Internet's most important measurement data indicating its size and growth was released yesterday by Mark Lottor of Network Wizards. The Domain Survey attempts to discover every host on the Internet by doing a complete search of the Domain Name System. The latest results gathered during late January 1995 are listed. For more information see RFC 1296; for more data see the zone directory on ftp.nw.com, or http://www.nw.com. Worth noting are the new host computer count - 4.851 million - and the 26% growth rate for 4th Quarter 1994 - the largest jump in the recent history of the internet. Internet hosts in the .com domain continue to surge ahead as the largest group. It's also worth noting that www-named host computer now constitute the most numerous on the Internet. The host count encompassed 90 countries having direct connectivity, as well as 7 transnational domains (com, edu, gov, mil, org, net, and int). The following extracts of Lottor's data were prepared by the Internet Society.

My grandfather, proprietor of such a store, on one Sunday morning, got such a call from a young lady. He recognized the voice -- it was the second time she'd made such a call -- and replied to the initial question with: "Why no, my dear, we've just let the old chap out to go to _Sunday_ School_!". There was an astonished gasp, followed immediately by a disconn- ect.

I continue to smoke because it shows that I am sophisticated, and it makes me glamorous and very attrac- tive. People give me this incredible look when I tell them that when I began smoking, cigarettes were *twenty-four* cents per package at the Walgreen's Drug Store, but you could get them for twenty-one cents per package at Safeway. Cigarette vending machines were incapable of giving back pennies as change, so you had to insert a quarter; when the cigarettes came out there was a single penny inserted in the pack under the cellophane wrapper. There were no warnings on the packages; where the warning goes now was taken up with further advertising or logos, etc. The warnings started sometime in the late 1960's I guess ... I don't remember. I vowed I would quit when the price reached a dollar per pack; then I made the same promise about two dollars per pack. Now I hunt for places to buy them that are less than $2.75 per pack.

Let me try to explain the Dallas/Ft.Worth LATA dialing issue in slightly more detail. The Dallas LATA is in area code 214, the Ft.Worth LATA is in area code 817. Both are served partially by Southwestern Bell and GTE, parts of each in each. (And no you don't get your choice yet, but for dialing purposes this doesn't matter.) If you get normal un-metered service in Dallas you can have unlimited dialing in Dallas LATA only. Likewise in Ft.Worth, you can dial in the Ft.Worth LATA only. To dial from Dallas to Ft.Worth is long distance and requires 11 digits. To dial from Ft.Worth to Dallas is long distance and requires 11 digits and you get charged for it. Now here's the kicker. For roughly $11 a month more (total residential local bill about $40/month), you can get a "metro" number that allows both incoming and outgoing calls from either LATA without charge using ten digit dialing. Example: I live in the Ft.Worth LATA and have a metro number 817-329-xxxx. I call Ft.Worth by using xxx-xxxx. People in Ft.Worth call me by using 329-xxxx. I call Dallas by using 214-xxx-xxxx. People in Dallas call me by using 817-329-xxxx. You tell people your phone number by saying: "metro 817-329.xxxx". Works nicely and I got used to it quickly enough, although this is apparently too difficult for some portion of the population. The deal is, if you don't have metro, whenever you want to call a number in the other LATA, you always try ten digit first in case they have metro. I've had people who lived here all their life and won't try to call across LATA because they're afraid it is long distance. I guess they are just technologically-challenged. BTW people that live right near the edge of the LATA are basically hosed without metro. There is a mall (Irving Mall) that lies right on the border. Some stores have Ft.Worth LATA numbers, some have Dallas LATA numbers. Nothing like a challenge, eh? There are some alternate service providers that have setups that allow metro-like service without having a metro yourself, but most of them are not too handy for a business.

This is a ridiculous proposition. Go out and ask your county tax assessor how they determine the worth of real estate for ad valorem tax purposes. It is certainly NOT whatever the owner says it is -- if that were the case, I'd declare the value of my house to be $1, and have to pay only a few hundredths of a cent a year in property tax. OR, I could make myself look very rich on a loan application, by declaring the property to be worth $10,000,000, but then I'd have to pay the high taxes every year. No, property value is determined by what a WILLING SELLER _and_ a WILLING BUYER, neither of whom are under undue pressure, are willing to spend/take for it. An apple is NOT worth $1,000,000 just because that's my asking price -- its worth will not be established until a sale actually takes place.

Growing up in GTE-land, they of course did things differently. Exchanges on phone numbers were single characters (ie H-5048 was Harrison, 'A' for Anthony, 'E' for Eastbrook exchanges, etc, and named based on the location of the exchange). Interestingly phone numbers were five OR six digits. Private lines were the five-digit numbers. Party lines were six (same five numbers for those on same line, with differentiating last digit for each party. I'm guessing this is the old Strowger mechanical switches, and them somehow the last digit was used on some type of stepper switch to determine the ringing frequenty to ring the specific party on the line?)

I can approach this two ways. One, when will the PC (powerPC, whatever) replace the automobile? The microprocessor in the average car is very weak. The microprocessor in a PBX is somewhat more central than the one in the car, but if you halted the CPU on most PBXs, calls would remain up. Clearly, the PBX is a lot more than the embedded programmable controller! Two, when will PCs be so reliable that they won't go down for more than two hours a year? When will PCs have hot swap of all cards, including the CPU and memory? (PBXs, except little ones, usually have fully duplicated controls running in a hot standby mode.) When will PCs have synchronous time-division buses for carrying isochronous traffic? > It will probably be a time curve: first available for small offices > (ten users) on an ethernet, then a while later available for 200 lines > on a faster LAN, etc. Etherphone is an ancient undergraduate project that comes up every couple of years. You _can_ hack voice onto Ethernet "but it would be wrong" for various reasons I won't detail, such as Ethernet's lack of timing determinism and delays. PBXs depend on isochronous bandwidth. There are LANs that have it, like IsoEnet and FDDI-II, but the economics aren't there ... > My Mitel sx200 lite has a 68000 for a processor: it's a MacPlus! > Surely the cpu horsepower is available to replace lots of dedicated > TTL and switching hardware.

But who are the startups that are > out to kill the PBX makers? The startups were there ten years ago. Following the 1979-1983 failed move to "voice and data PBXs", a couple of startups got fair dinkum change to "merge the LAN and PBX". The two best known were CXC and ZTEL. CXC eventually gave up on the LAN side and built a PBX/ACD that may have sold okay, I don't know. ZTEL was a major disaster, never really worked, and lost its investors many millions of dollars. Folklore has it that some of the founders really knew it was unlikely to succeed, but figured that the pitch would attract venture capital and make them rich in the meantime. (Of course, that can be rumored of a lot of venture-funded startups.) There's a good reason why all successful PBXs are based on architectural notions first widely deployed in the 1970s and only marginally refined since then! (P.S. Back in '77, I assisted in writing a book called "Dimension PBX and Alternatives", which surveyed the early computer-controlled PBXs. The implementation details have changed since then but the fundamentals haven't.) The real excitement in PBXs is in open inter-CPU links, allowing external processors to communicate in real time with the PBX. This is the whole Computer Integrated Telephony business which is finally making a big splash in the call center arena, and in some other markets. Fred R.

My number was enabled last weekend, and is reachable from Nynex-land. There have been a number of problems, both temporary and permanent. The worst problems are that 500 numbers are not reachable from overseas (by design according to AT&T), and that you need to use an AT&T accepted calling card to call them from payphones, hotels etc. This last one is a real kicker -- especially as the messages that you get when trying to call the 500 number give you no idea as to what went wrong.

I know of only two cases where PUBLISHED instructions had some ambiguities arise which could only be resolved with time-out. They are both in the history file: 1. for many years after 1973, area 213 in California continued to publish 0+7D for 0+ calls within it. This would have created ambiguities such as 0-413-xxxx and 0-413-xxx-xxxx. 2. Denver and Adamstown, PA are served by Denver & Ephrata telephone company, which used to serve parts of 215 and 717. Denver and Adamstown were in 215 but did not adopt the "no 1" which Bell of Pennsylvania was advertising for long distance within area 215 ("no 1" meant to stop using the leading 1 for what had been 1+7D) when NNX prefixes were running short there. (Denver and Adamstown later switched to area 717, having been faced with an area code change anyway due to the 215/610 split. Denver switched from 215-267 to 717-336 because of 717-267 being in use elsewhere; the 484 prefix at Adamstown merely switched area code.) [TELECOM Digest Editor's Note: Carl is referring to the 'history.of.area. splits' file in the Telecom Archives; a file which gives in great detail the dates when area codes broke away from other codes, the geographic areas involved, etc. It is a very interesting file, in case you have not ever seen it.

I've been experiencing modem problems with the recent S. California rains, and I suspect my outdoor termination box has something to do with it. I have a six-pair cable coming in off the pole (plus two for the downstairs neighbors terminated in little single-line boxes and a forrest of abandonded lines) into a six-line screw terminal box. One line is my voice line, one is my "modem" line, one is for a roommate, and one is for a room normally occupied by another roommate. I'm also planning on installing ISDN soon, and was wondering if they would wire it into that box or give it it's own. I'd kinda prefer that it go into this box (or it's replacement) since that gives me more flexibility going into the house wiring. The box is kinda-sorta weatherproof -- it has a flip-open cover, but the openings for the wires to come in and out are on the side and pretty big. The terminals don't seem to grip the wires too well, either. What kind of boxes are in current use (and which is the "best"?) for outside termination? (I don't know if this is the right term - what I mean is this is the point where it interfaces to subscriber lines...) Will PacBell change the box for me if I complain? Or is the box my responsibility? Will they move it into the garage (other side of the house) if I request it? Or are they only responsible for getting it to a point close to the drop? What about the ISDN line? Are they going to put another box on the side of the house, or will they put it in the garage? Or use another pair on the 6-pair box?

Date: 9 Feb 1995 22:30:23 GMT Organization: Dept. of Comp. Sci., Victoria Uni. of Wellington, New Zealand. One thing that worries me about CTI is the requirement to re train users. I manage a PBX network for a university. One of the major problems we have is the ability to get people to learn new ways of doing their job. It seems that a hazard with voice is that a lot of peoples attitudes regarding their telephone is that it interupts their work. For this reason it is hard to get them to learn ways of improving their use of it. CTI in a large enviroment like ours maybe inexpensive to install, however what about the costs of training the users in using the technology, and getting them to use it. Don't get me wrong, I think the technology has its uses eg 0800 call centres, small offices etc, but in an enviroment of 1000 + users who do not comprehend its benefits, it could prove to be a nightmare.

That would leave a 56/64 kbps circuit as the remaining choice. You can get 7.5 KHz out of it with ITU-T G.822 standard codecs, even more with Musicam. I guess you are aware of the Herb Squire Tests? This should never be a problem on a carrier current station unless everything in the audio chain is over compressed everytime it gets processed. So price a DDS line to your remote sites and if it is cheaper, start adding up the cost of the CSU and codec, otherwise stick with what you have, it's probally more reliable anyway. FWIW, reqular program channels are often digital anyway. The LECs us a program channel card in a D4 channel bank with one time slot used for each 2.5 KHz bandwidth.

When I was in high school, about four years ago, our school was the first public school in California to contract with Whittle Communications for Channel One. There was a bit of local controversy about thecommercial content, but the parents and staff decided that the two minutes of commercials was worth getting 100 televisions, a campus ethernet network, and CD-ROM on demand, and a television editing/broadcasting studio. Whittle actually paid for everything (except for the ethernet) -- I guess we were too good of a "Captive audience" to pass up. The interesting part is that the California Superintendent of Schools (at that time Bill Honig) sued our district in state circuit court. THe state legislature also tried to make such agreements illegal. Neither attempt was successful though. The system was actually quite impressive. At 4:00am, the satellite dish tuned to the proper channel and began recording that day's program. Then at 10:15 (when the school decided to re-broadcast the show to the classrooms) a second timer started up the VCR and played the tape (the librarian could also hit the "red button" to make the tape play immediately). The interesting part is that the tape had some kind of signal that automatically turned on ALL of the TV sets on campus. When the program was over, the TV's would go off. Any idea how this was done?

The Clearview (I-295) was built as an alternate to the loop, running from the Throgs Neck Bridge to JFK, but was never completed. Someone also had the idea of extending the loop into the Rockaways and Nassau County via the Nassau Expressway (I-878), but that has since been turned into a local-access highway (NY-878).

I actually agree with most of what Tony has to say, and his attitude is perfectly understandable, as he was nice enough to note what company he works for. My point is that not only is ADSI here NOW, it is low-cost and will work on the current, analog lines which everyone has. Let's face reality here -- if just 10% of the CURRENT Internet users suddenly had full WWW capability, and used it, they'd bring the Internet to its knees. And WWW is a far cry from full-motion video and CD-quality audio bandwidth! (Remember what happened to the Internet bandwidth that Friday two Decembers ago when the DOOM shareware was released? And that was just a bunch of users trying to FTP a 3meg shareware game!) I would personally LOVE to have all the pie-in-the-sky things that AT&T advertises in their commercials. (Especially that neat gadget the guy uses to send faxes from the beach, but it sure ain't no Newton.) However, lets face reality for a moment. None of that will happen in five years, a little of it may be in place by the turn of the century, but only in major markets. Oh, I'm sure Redmond, WA will be wired to the hilt with fiber optic cable, and be a marvel, but what about the rest of the world? No one will front the money to increase the network bandwidth that much! (Including cable companies...) GTE's long-term Cerritos experimental cable project showed that people were mildly impressed with the gee-whiz stuff, but when it came time to pony up hard cash, they were nowhere to be found. On the topic of ISDN BRI ... even in the cities where it IS offered, AND you are lucky enough to be in the part of town where the only ISDN-capable CO is placed -- if you live more than a few kilometers from the CO, no ISDN BRI for you. And, the way it is priced locally, it is cheaper for me to have two POTS lines, one for my modem, one for voice. (Actually, I live in a rural area, and Bell just changed my local service from a crossbar switch to a 5ESS a mere two years ago. Plus, I am STILL on a loop extender, so, no ISDN BRI for me either.) We won't even talk about what an ISDN BRI telephone with data capability costs. By the way, don't forget that all those new, be-here-any-day-now voice and data-simultaneously modems working on analog lines are going to have to do considerably better than a mere 4:1 compression ratio. And, there ain't no way they'll connect through an AT&T SLC96 which has channel compression turned on, but the ADSI phone will. In the REAL world, most households do NOT have PCs that are multimedia -capable, and they are losing ground now that MPC-II is out. (I have an aging 486/33, 8 meg of RAM, with a sound card and single speed CD-ROM, and when I recently installed Microsoft Encarta on it, the install program smirked and informed me my PC was barely adequate. So depressing ...) Those households with PCs mostly don't have modems. If they DO have modems, most never use them to connect to an on-line service. Super, two-way cable boxes aren't here now, and won't ever be here for us rural sorts who don't have cable anyway. (Half the country.) I DO have a satellite dish which accepts full-motion video with CD-quality audio, but its only return path to civilization is a built-in, dial-out only 1200 bps modem that goes off-hook secretly in the night and informs Big Brother each month as to what pay-per-views I bought. The point is, ADSI is a simple, cheap technology that provides Caller ID on Call Waiting, and has an extra feature that also allows simple text interaction between home and businesses. It is targeted at the majority of the population that eyes a PC with suspicion/derision, but has no qualms about using a telephone, even if it DOES have a screen. And, it doesn't need Bellcore to champion it -- the RBOCs will take care of the issue by offering to sell/lease the hardware at cost, knowing they'll make their money by increased sales of calling features on home phone lines. Bell Atlantic did this a couple of years ago with simple Caller ID number-only boxes, and moved more than a half-million in no time. (Of course, they regret that now, as they are meeting resistance from those purchasers when they suggest trading up for a fee to get a Calling Name and Number ID box.) I have a brief war story that helps demonstrate the real world of telephony vs. the world of Microsoft. (Is it Win96 yet?) Several years ago, GTE shipped tape units intended for installation for their COs. Each unit came labelled all over with warnings that one in five units were known to catch fire when powered up! The reason this seeming idiocy occurred was that the tape units were pivotal to complying with a new telephone numbering plan that was to go into effect on a given day. These cutovers are planned years in advance, and once agreed upon, they WILL HAPPEN that day. There was no time to fix the tape units, so, GTE installers stood by with fire extinguishers when the units were first powered up, and the cutover took place on the appointed date. Until Bill Gates understands that sometimes dates DO matter, Microsoft won't qbe replacing COs with super PC servers running NT. (Remember that brag?)

Actually, there is a reason for them to return supervision on 0-500 calls. If they did not, it is unlikely that the cellular companies would allow such calls at all! While you may not "PAY" for the time that you spend programming the service, I do not really want to give you free use of my most scarce resource (radio channel time) while you are setting things up. It is not really AT&Ts place to chose for me which calls I bill for and which I do not by selectively manipulating the return of answer supervison. If the call is answered, even if answered by a machine, AT&T needs to return supervision. The only exception to this is when they return call routing exception recordings (which is certainly not the case here). > 5.

Actually, most cellular companies do not perform ANY form of casual billing. This includes 900, 976, 800-chargeback, 10XXX billing, and now 500. Its not clear when this will (or if it will, or if it even should) change.

The Panasonic switch is kind of strange, because it is a hybrid in that it can use either its own proprietary sets, or simple 2500 sets (like a home telephone), without adaptors (a switch like the Northern Telecom Norstar can use a regular phone, but you need an ATA adaptor .. $) The first solution is that Panasonic makes its own voice mail package that integrates with the switch. I'm not sure what the cost is like, but if its like many vendors' prices, it's ridiculous. Your other option, third party stuff, may be limited. I know we played around with a Panasonic switch and found that when you utilize a regular phone (ie: voice card) on the system, it does not pass any station or trunk ID to you. In other words, if a call came in for Bob, the system could answer it and then transfer it to his extension. (you can use a dumb set of key commands to accomplish this). However, if Bob does not answer, or his set is busy, there is no way to tell the system where it should go (ie: to his voice mailbox). This is avoidable if you set up a different extension on your switch as a personal voice mailbox, but you need a voice card line for each one, etc ... etc ... etc. Bottom line: setting up a system on a Panasonic would be pretty involved, and would not be very integrated. If you can expand on your explanation of exactly what you are using it for, maybe there is a different way to approach. But if you are looking for typical corporate voice mail, it will be a challenge if you're not using OEM add on stuff from Panasonic. gregicg@cadvision.com Greg Habstritt Intellitech Communications Inc.

Garbage receivers are never a factor in AM broadcast program circuits. Most AM broadcast transmitters manufactured today are essentially flat up to 10 kHz, with some rolled-off to comply with occupied bandwidth regulations. However, I used to have a 5 kW RCA plate-modulated transmitter that was flat to 15 kHz, at one place I worked. Program circuits with quality less than 8 kHz generally make the station sound like a garbage can with the top in place. ;) > One more thought, especially if you want to save money.

Radio stations require full-period circuits with no interruptions, and very fast response time. Do you really think any MIS group would keep someone on-call to drop everything and service their circuits after 5 p.m.? It really depends upon whether the radio station is important to anyone. If it is, they'll find the funds to keep operating. If it isn't, they won't. > [TELECOM Digest Editor's Note: New York City has twenty blocks to the > mile? Gee whiz ... they must be very small blocks. They're only "small" in one direction, and much more consistent in size than you're use to. However, because of the density of occupied space, and poor plant management practices by New York Telephone, circuits may not take the paths you might expect to get from point A to point B. > In Chicago we have eight blocks to the mile with the exception of > one area just south of downtown where there exist twelve blocks to the > mile, and that's only for about one mile. But you also have a downtown area that's literally dieing, municipal incompetence that resulted in flood damage to a mind-boggling number of buildings and tenants with incalcuable financial damage, and a highway system that's in worse shape (as a whole) than New York City's. [TELECOM Digest Editor's Note: I'm not quite sure what the number of blocks to the mile has to do with the incompentence of our city fathers and the general undesirability of living in Chicago these days. I agree with your assessment completely, and have so stated many times in the past here. But one thing they possibly do right in Chicago is have some consistency in the street numbering.

The costs of installing 900 lines of your own for one project will almost certainly be prohibitive. You should contract with an established service bureau for your project. Most service bureaus have the capability to program your application on their equipment (they can dynamically allocate the equipment to serve many client programs, so they get very good efficiency from the use of the equipment and phone lines). They will probably charge you a one time set up fee for the programming (approx $1000 for your application, I would guess), and a "cents per minute" fee for call processing (possibly with a monthly minimum). Let me know by e-mail if you want referrals to quality service bureaus. A few service bureaus will allow you to provide your own equipment. The bureau will provide space, and carrier hookup for 900 service. You'll need to install and maintain your own equipment at their facility, so you need to select a vendor that is close to you. They may charge you a fee (maybe about $250/mo.), and they will provide you with the 900 hookup at the published carrier rates (they earn some profit by re-selling the 900 service to you, so they usually do not charge you an explicit usage fee when you provide your own equipment). From your email address (...mit.edu), I assume you are located in the Cambridge, MA area. You might want to call Thad Ward at Tele-Publishing (617) 859-3385 for advice and a quote for your project. Let me know if I can help further. FYI I am an independent consultant, specializing in Computer Telephony systems integration. Although I am no longer directly involved in the 900 industry, I know quite a bit about it because until recently I owned and operated a 900 service bureau business which I founded in 1986. ------------------------------ From: lemson@ux1.cso.uiuc.edu (David Lemson) Subject: Re: Long Distance Caller ID Date: 09 Feb 1995 23:13:41 GMT Organization: University of Illinois at Urbana Reply-To: lemson@uiuc.edu Paul J Zawada writes: > Having been frustrated with having Caller ID in Champaign, IL for over > six months and having ~70% of my calls come up with "OUT OF AREA", I > decided to call Ameritech and try to figure out whether or not I > should keep this near-useless service.

When a friend who lives about eight blocks from my parents near Ballwin, MO called me, I got his number on my box. However, when my parents, who are in the same exchange (314-458), call me, I always get an OUT-OF-AREA. Something is pretty screwy. I have one guess -- I know that my parents are actually in the Pond, MO exchange, so they have an FX 314-458 number. It's possible that my friend is just close enough that his number isn't FX, so SWBT is passing the number through the LD carrier. It's also possible that my friend is using AT&T or some other carrier, which is passing the information through SS7, and my parents' LD carrier (Sprint) isn't. In any event, the Champaign switch *is* receiving a LD Caller-ID number somehow. David Lemson (217) 244-8833 University of Illinois Computing & Comm Services Office System Administrator Internet : lemson@uiuc.edu BITNET : LEMSON@UIUCVMD [TELECOM Digest Editor's Note: I don't think the possibility of FX has anything to do with it. If 314-458 is handing out ID's carriers it connects with, then it is doing it for all customer's on that exchange. If your parents had an FX line, you'd know about it, because they would have gone to bankruptcy court long ago! Those things are quite expensive; I have yet to see one in a residence, and these days you don't find many in business places either with so many other alter- native ways of processing calls which are less expensive. If anything, I would check with your friend and see what long distance carrier he used to call you, and then find out what carrier your parents used. We are told here in the Digest recently that Willtel is passing along the ANI to the distant end where it is converted to Caller-ID. See if there is a difference in carriers used by your friend and your parents as that more likely is the reason you got ID on one and not the other.

Goodin) Subject: UCLA Short Course on Fuzzy Logic, Chaos, and Neural Networks Date: Thu, 9 Feb 1995 17:52:00 Organization: UCLA Extension On May 22-24, 1995, UCLA Extension will present the short course, "Fuzzy Logic, Chaos, and Neural Networks: Principles and Applications", on the UCLA campus in Los Angeles. The instructor is Harold Szu, PhD, Research Physicist, Washington, DC. This course presents the principles and applications of several different but related disciplines -- neural networks, fuzzy logic, chaos -- in the context of pattern recognition, control of engineering tolerance imprecision, and the prediction of fluctuating time series. Since research into these areas has contributed to the understanding of human intelligence, researchers have dramatically enhanced their understanding of fuzzy neural systems and in fact may have discovered the "Rosetta stone" to decipher and unify these intelligence functions. For example, complex neurodynamic patterns may be understood and modelled by Artificial Neural Networks (ANN) governed by fixed-point attractor dynamics in terms of a Hebbian learning matrix among bifurcated neurons. Each node generates a low dimensional bifurcation cascade towards the chaos but together they form collective ambiguous outputs; e.g., a fuzzy set called the Fuzzy Membership Function (FMF). This feature becomes particularly powerful for real world applications in signal processing, pattern recognition and/or prediction/control. The course delineates the difference between the classical sigmoidal squash function of the typical neuron threshold logic and the new N-shaped sigmoidal function having a "piecewise negative logic" that can generate a Feigenbaum cascade of bifurcation outputs of which the overall envelope is postulated to be the triangle FMF. The course also discusses applications of chaos and collective chaos for spatiotemporal information processing that has been embedded through an ANN bifurcation cascade of those collective chaotic outputs generated from piecewise negative logic neurons. These chaotic outputs learn the FMF triangle-shape with a different degree of fuzziness as defined by the scaling function of the multiresolution analysis (MRA) used often in wavelet transforms. Another advantage of this methodology is information processing in a synthetic nonlinear dynamical environment. For example, nonlinear ocean waves can be efficiently analyzed by nonlinear soliton dynamics, rather than traditional Fourier series. Implementation techniques in chaos ANN chips are given. The course covers essential ANN learning theory and the elementary mathematics of chaos such as the bifurcation cascade route to chaos and the rudimentary Fuzzy Logic (FL) for those interdisciplinary participants with only basic knowledge of the subject areas. Various applications in chaos, fuzzy logic, and neural net learning are illustrated in terms of spatiotemporal information processing, such as: --Signal/image de-noise --Control device/machine chaos --Communication coding --Chaotic heart and biomedical applications.

Basically, if you are calling anywhere inside about 18 miles from a flat-rate line, the call is free and unmetered. If you live on or near the shoreline, you could theoretically only have 50% the "free" calling area of someone who lived at least 18 miles from the ocean, since half of your 18 mile radius could be out on the Pacific. Since the "basic monthly fee" is in theory supposed to cover those "local" calls, aren't those of us on the shoreline getting cheated, since we pay the same basic-rate? Should unmeasured service therefore cost less if you live near the ocean? I'm curious to know what everyone thinks of my idea.

This saves 30% over the leased copper lines of the same capacity. What drives the cost and payout up is the equipment on each end. To get an even more cost effective T1 is Halcyon's product that will take a 4 wire dry circuit and convert it to T1. This has been quoted at $3000 per end, but the monthly leased 4 wire circuit is only $28. This pays out much faster. Telco Systems makes a T1 interface that will give us 48 2500 or digital extensions from the Northern Telcom for $25,000 per end, but couldn't I do that with just multiplexors? I would think so, especially with 2500 sets. Where my knowledge is lacking the most is the T1 connectivity to the PBX and the 2500 sets at the remote end. Does a MUX covert 2500 set dial tone to T1 compatible signalling and then back to dialtone on the remote MUX? If so my answer would definately be 4 wire dry pairs with the Halcyon T1 convertrs. Alot of people suggested microwave. Interesting, but I would imagine that the DES encrypting is expensive. I also worry about weather and lightining storms. If the microwave went out, 1/3 of our operations would be dead without a copper backup. If we have to keep the copper backup, why bother with the microwave?

V.34 modems will *NEVER* give "true 115 kbps data throughput"! That is the theoretical *maximum* burst throughput. In reality, even with highly compressible text files, you're lucky to get more than half that. With files that are already compressed, such as ZIP/StuffIt/gzip/ etc. or JPEG/GIF/etc. files, you will get negligible compression from the modem. As a test, I once took a text file that was a PostScript page. Compressing it with gzip, I got a compression ratio of over 30:1 -- the compressed file was barely 3% of the original size! Running it over my modem, it was compressed by a ratio of 2.2:1. Thus, it is entirely fair to say that a 56K ISDN line is twice as fast as a 28.8 modem, and a 112K ISDN line is four times, because if you are sending files of any significant size, you should compress them on the computer, not on the modem.

Ron fails to mention that the ROA/E+ plan requires you to pay for your first 60 minutes of calls in advance at a rate of .125/min ($7.50). However, no one plan can nor will ever be perfect for everyone. I have been on the ROA/E+ plan for a couple of years now and am very satisfied with it. It provides a discount off of intrastate calls as well, and the time restrictions are perfect for me since I'm usually not home when the plan is not effective. However, Sprint called me at one point and dangled some type of incentive in my face to join their MOST plan. I thought, why not? I'll take their incentive ($50 I think) and switch back in a couple of months and life goes on ... until I got my first bill. I allowed then to switch my modem line only, which I use almost exclusively to connect to CI$. As it turned out, the CI$ node I use apparantely was also a Sprint line, and since that's who I called the MOST, I received a 20% discount, giving me a .0975 rate, BUT only between 11pm and 7am. It was great for a while, but as lifestyles change and such, 11pm became the wee hours, and then AT&T changed the ROA/E+ plan to begin at 5pm instead of the prior 7pm, and I switched back. Moral of the story? Beats me, but I do know that it takes a lot of trial and error to find a long distance calling plan to suit your particular needs. I personally wish these carriers would stop all this cut-throat quasi-deceptive advertising with two-second fine print and just give us the facts we need to make an informed decision.

The judges took an interesting position that the "GREATER IMPACT" OF ELECTRONIC MEDIA and its "wider range of circulation of information" as opposed to the press, CANNOT BE USED TO RESTRICT or deny THE RIGHT TO FREE EXPRESSION. This may have important consequences, for all over the world, including in the US and India, the electronic media is denied freedoms allowed to the press with the excuse that it's somehow different. The three-judge bench, comprising of Justices PB Sawant, S Mohan and BP Jeevan Reddy, made the ruling after an government appeal against a previous ruling by the Calcutta High Court. The Calcutta High Court had earlier upheld the right to telecast as fundamental, which would theoretically prevent any regulation or censorship whatsoever. The consensual Supreme Court judgement, while denying the government's power of monopoly, upheld its right to subject the electronic media to regulation and censorship. However, Justice Reddy, in his separate ruling did not mention censorship. He pointed out that the century-old Indian Telegraph Act of 1885, which has been ingeniously extrapolated to support the government's monopoly over electronic media and right to 'licence' data networks, was "wholly inadequate and unsuited for" electronic media, and said that Parliament should enact new laws to govern such media. Unfortunately the Supreme Court has no powers to legislate, and new laws have a habit (as seen with the Digital Telephony Bill in the US) of increasing, rather than decreasing, government authority. The explicit statement that the electronic media should not be more restricted than the press will, hopefully, prevent that. The legal battle started with the Doordarshan, the state TV monopoly, objecting to the Cricket Association of Bengal's contract with Trans World International granting the latter worldwide broadcasting rights to a cricket tournament. Doordarshan used the 1885 Act to prevent TWI from uplinking to satellite, till the courts intervened.

The network, internetwork and higher layers vary widely depending upon situation and application. The data link layer is the one most in need of study and understanding. This is the layer concerned with the actual transmission of data, and its reliable receipt. Three chapters relate to the basic concepts of the data link layer, an introduction, error detection and correction, and controls. The remainder of the book concentrates on the specific protocols; BSC, HDLC, LAPB, LAPD, LAN protocols, LLC and so forth. Two chapters are of particular interest to the online community, covering asynchronous file transfer protocols (X modem and descendents, Kermit, and others) and LAPM (Link Access Protocol for Microcomputers or V.42). Frame relay and Internet protocols are touched on. This work deals with the concepts rather than implementations. The actual programming of specific protocols will require additional detail. However, for an understanding of the options at this layer in the stack, this is a good starting source. copyright Robert M. Slade, 1995 BKDTLKPR.RVW 941229.

Are you sure you read *my* book? Straight Talk About the Information Superhighway is not a collection of essays. It's a conventional nonfiction book, with each chapter building upon the last, mostly analysis on my part but with lots of quotes and other information from those in private industry developing the technology, those in the goverment promoting and overseeing it, those in the nonprofit sector who are trying to steer it so it benefits the public interest, and those using today's online services. You may feel it's a collection of essays because this was a line used by one of the publisher's promotion writers.

But the book is mostly about how lifestyle and workstyle issues, how the information superhighway will likely affect our jobs, the way we educate our kids, how we vote, entertainment and shopping, how we gather news, and how we communicate and relate with one another.

Darcos & Company, Silver Spring, MD USA Subject: Area Code 500: It Doesn't and Does Work - or Both Our next message on NPA 500 is subtitled "Fun and Games with Bell Atlantic" for reasons which will become clear. TELECOM Digest Editor noted: > TELECOM Digest Editor's Note: [deleted] *my* 500 number started > working perfectly today. [deleted] when I use my own phone to dial > 1-500-677-1616 (my number) it rings once and I am told it will try > my alternate numbers (because it found my home number to be busy). > When I do 0-500-677-1616 and tell it to bill the call to the phone I > am using, it vanishes for a couple seconds and I get call-waiting ... I decided to try the number to see if it works here or not. Here in Montgomery County, Bell Atlantic does the following: 0-500-677-1616 returns a SIT tone ("") followed by "We're sorry, the number cannot be completed as dialed, please check the area code and the number and dial again. Thank you." Then a rude rattling noise and it repeats; this sounds like a local recording. 1-700-555-1212 "You have reached the AT&T Long Distance Network" (Yes, I know the "official" number is 555-4141, but this one has worked with AT&T, MCI, and Sprint for over ten years and I've gotten in the habit of using it.) 1-500-677-1616 AT&T's sound mark (" AT&T") and it begins a ring. I hung up at this point. (No offense intended, Mr. Moderator, but I just wanted to see if the system worked or not, I really didn't have any reason to call you.) 10288-0-500-677-1616 AT&T's sound mark (" AT&T") then "True Connections" and then asks me for a pin or a calling card number. 10288-1-500-677-1616 returns a SIT tone ("") followed by "We're sorry, it is not necessary to dial a carrier access code for the number you have dialed." 10222-0-500-677-1616 Gives me a live MCI operator, probably because they cannot route this call. (I wanted to check; I never can be sure with Bell Atlantic what might happen.) This was cute; real cute. I then decided to see how much fun I could have reporting this to 611. That was even *more* interesting. (Note: I made the try via MCI's 10222 carrier code after calling 611 because I didn't think of it until later.) After going through a couple of voice mail menu prompts, the attendant answers. When I give her my number, I gave her my virtual alternate ring number, only to have her tell me that's not the number I'm, calling from. (I never use the "real" physical telephone number so I don't even know it.) After I give her the main billing number which is a different line, she then plays a game of asking me the main number which I don't know, I already told her I don't know, and *which she has on a screen in front of her, since later she proceeds to inform me of the correct number*. Finally we get that taken care of. Also, they *still* have the *former* owner of this number listed as the subscriber. I've had this number for over three years, but they still don't have it right. After I tell her that I *can* dial 1-500 or 10288-0-500, and *can't* dial 0-500 or 10288-1-500, her response is to ask me if this is a problem from other phones in the house, and "Could there be a problem with your dial pad?" I was about to try a different phone (which I knew would have the same problem) when reality set in and I realized that the question didn't make any sense. I take a deep breath to calm myself and explain carefully that if there was a problem with the dial pad, it would not have worked when dialing the carrier access code first, either, would it? She then conceded this point. Then she proceeds to suggest it's a carrier problem! I explain to her two points, first that the refusal to accept 0-500 sounds like it's Bell Atlantic's recording, and that the carrier access code not allowed recording must be theirs, and second, that the 500 area code is similar to the 800 area code, the numbers are carrier specific and shouldn't even *need* a carrier access code, thus I believe the problem is in Bell Atlantic's switch. Grudgingly, she agrees to write up a trouble ticket and I give her the number so they can check on it; (Pat, if you get a "strange" call from *Bell Atlantic* checking your 500 number from *AT&T*, I was the one who caused it). We shall see what happens. Based on my prior experience will Bell Atlantic, I hope this is a "difficult" problem; that they can fix easily. If it's an "easy" problem, then I'm worried they will make a mistake and I'll end up getting my phone service switched over to foreign exchange service from West Virginia or something else. :) [TELECOM Digest Editor's Note: I got a weird response today when trying my 500 number from the McDonald's Restaurant where I had lunch. O-500 worked fine, and as expected when I pressed # without a pin the response was that the call had to be billed to a calling card. No other options were given. So far so good. Then I tried 1-500 and got the intercept usually given out on phones restricted from 900/976, i.e. "the call you have dialed cannot be placed from this telephone. An operator will not be able to place the call for you." Instead of hanging up, I stayed on the line and after a couple seconds, ringing started ... it rang twice and a new intercept came on the line, "your call cannot be completed as dialed, please check the number and dial again, this is a recording 708-1T". This happened three times in a row, from 708-677. Now didn't someone write here just a couple days ago and say that when they tried 1-500 from a (genuine Bell) payphone that the call was auto- matically dumped to 0-500 and dealt with that way?

Peak is 8am to 5pm your time, Monday through Friday. Pat - I called AT&T to ask about a 500 number I had reserved. They had no record of the reservation. I then asked if I could reserve the number again. They said that they did not have the prefix I had requested (467). I presume this is why they dropped my reservation request. All of which brings me to my point. If different carriers "own" different 500 number prefixes, I would expect each to set its own rate. While AT&T might charge .25/.15, Integreslime might charge $5.00/$4.99. This would be a big ouch to the hotels. Keeping up with all of the carriers and all of the rates would be challenging at best. Were it my switch, I would probably block 1-500 calls. Trying to allow direct dialing and hoping to recharge accurately would not be practical. 0-500 calls might be OK, but so many slime carriers ignore billed number screening. If the bill just appears on the local telco statement, it is too hard to screen the bills looking for fraudulently billed 0-500 calls. The only way I would allow 0-500 calls would be if the local telco refused to bill for the teleslime. If the teleslime has to send in a separate bill, it is easy enough to discard. Dave Ptasnik davep@u.washington.edu [TELECOM Digest Editor's Note: Well you are correct that once the others get into the act, it will be a lot harder to keep track of. I only answered Mr. Kipps on the basis of AT&T, which is -- so far as I know -- the only player in 500 right now, although other telcos do have prefixes reserved for themselves. If anything though, I think the others will try to be competitive with AT&T on this service. The only cases where you get the outrageous, non-competitive pricing (such as your $5.00/4.99 example) are when the teleslimes have a more or less captive customer base such as COCOTS in out of the way places, correctional institutions, etc. They know if you are at a COCOT on a street corner somewhere calling collect, you probably -- for whatever reasons of your own lifestyle, etc -- do not have much choice in the matter, so they pull out those high rates. And of course, there is always sex: the teleslimes who specialize in hot chat with very high billings per minute also have many users without a lot of options (the user is aware of) ... and a need which requires attention. But who in their right mind would sign up with teleslime for a 500 number where *they* had to pay that $5.00 rate on calls made to them with pins or where anyone calling them had to pay the same? See my point? People who get 500 service are probably going to more sophisticated than that. So you may get cases where Ameritech (one company proposing 500 service) may charge 26/13 and Sprint may charge 24/17. Each one will offer some different little gimmick in their version of 500, and as so often happens it will be an applications-driven thing as to which works out best for each individual user over a long period of time. But I really cannot imagine the teleslimes getting in on this and trying to adapt it to their high prices and otherwise scam operations. Who would accept it? With that in mind then, if I am correct, I would still maintain hotels and other PBX admins can probably deal with 1-500 without too many hassles. Whoever gets in the game will probably have rates that follow AT&T closely or are cheaper -- probably never more expensive. So what you do is, as long as everything coasts along in that 25/15 - 24/17 - range I expect they will also use, live with it. Watch for the occassional big charge, and when/if it starts to get out of hand, *then* clamp down. PAT] ------------------------------ From: TELECOM Digest Editor Subject: A Strange Man Calls Me About 500 Date: Fri, 10 Feb 1995 12:30:00 CST This happened several days ago. You may remember we had an article here listing the prefixes assigned in 500 service, and the telcos they were assigned to. A day or two after that article appeared, I got a note from the sysadmin here saying he had received a call from someone who wanted to know 'how to get in touch with TELECOM Digest'. Normally any inquiries about the Digest mail, problems, etc are just handed over to me by the admin. The fellow called the admin on the phone to ask how to reach me and the admin wisely said he would take a message and relay it. I got email from the admin and returned this fellow's call within five to ten minutes. I called him on that MCI common-subscriber 800 number, where you call it, then enter a pin to be directed to the subscriber. This fellow answers the phone by using my name: "Ah hello Mr. Townson, Thank you for returning my call." ... ... this fellow said he did not have an email account, and 'did not know that much about computers' but he was hoping I could send him a copy of that list of carrier prefix assignments for 500. He wanted to know where I got it. I told him it was sent in by a reader, and mentioned the site where that reader could be contacted if he had any questions. Ah, he said, he certainly was familiar with that site, in San Jose, CA. I tossed out the phrase "Bellcore" and he knew all about them also. I told him I couldn't help wondering how, since he had no email and no computer, he would have known about a not that well known public access Unix site in San Jose. He claimed he read about it some magazine. He claimed he wanted to obtain a particular 500 number -- a vanity number -- but it was not available from AT&T so he thought he would find out which company did offer it. I asked him how he heard about TELECOM Digest. Now get this: He told me he was located in Brooklyn, New York, on Avenue U near Flatbush Avenue. He had gone to his local library to see what the reference librarian could tell him. The librarian gave him a few sources for telecom information and he 'decided' to try this Digest. In a book giving internet resources he found that the Archives are housed at MIT. He called some person on the staff at MIT who knew from nothing about the Archives. Then he noted that this resource guide referred inquiries to 'telecom-request@eecs.nwu.edu' so he called Northwestern University to ask about the Digest. He finally was connected with the sysadmin who took the message for me. All this, mind you, because he had heard 'from someone' that the Digest had printed, a day or two before, a list of exchanges assigned to the carriers doing or planning to do 500. I asked this fellow who he was and what he did for an occupation. He claims he is 'a retired cab driver'. He sounded to me like he was in his late sixties or even perhaps his seventies. All this time I am thinking to myself he knows far too much to be a retired cab driver in Brooklyn. For a retired cab driver in Brooklyn who has no email, no computer, 'not much computer knowledge' he certainly knows a lot about unix sites in San Jose and how to get ahold of site admins at MIT and Northwestern. He claims he 'bought a computer but never did take it out of the box; it is still sitting in the corner, maybe I should set it up.' I asked him how should I send the message to him with the listing he asked about. Maybe he would like to give me a more precise mailing address. Ummm ... well ... would I read the list to him over the phone? He asked about a couple of companies on the list; rattles off who they are subsidiaries of; wants to know about a couple prefixes in particular. I asked if he had a fax machine; if so, give me the number and I will fax the list. He stalls me on that one also. He says he has a fax but would have to set it up, and 'maybe I can get back to you in a couple days with the phone number it will be on ...' I am holding my nose ... something stinks at this point. I mention that given his location, Avenue U and Flatbush, I believe he must be right by the Bell System international cable which runs close to there. He knows all about that also. He told me he has 'half a dozen 700 numbers', a couple of 800 numbers, and he wants a vanity 500 number. 'Just an unemployed, retired cab driver from Brooklyn .. not much to tell about me ...'. What ticked me off the most was when I called the MCI 800 number using the pin he left, he *knew* it was me calling, even though he claimed 'it was just a guess, I was not expecting any other calls on *that particular* 800 number this afternoon ...' Anyone have any ideas who he is? It just all seemed very odd to me; his persistence in locating me by telephoning MIT, getting no where, then telephoning Northwestern, then knowing when I called back, claiming no email or network connection of any kind -- indeed, not even a computer installed -- but he immediatly recognizes the name of a site on the other side of the country; he knows far, far too much about the industry to be a retired cab driver in Brooklyn, 'living near Avenue U' and wanting his own vanity 500 number to go with his 'several 700 numbers'. He knows about Bellcore and obviously about 800 ANI. I'd like his name and address please, if possible. He wouldn't tell me himself.

Contact: Karen Logsdon NeXT Computer, Inc. 415-780-3786 or Carol Aarhus MCI 1-800-436-9749 MCI SELECTS NEXTSTEP TO SUPPORT FRIENDS & FAMILY CUSTOMER SERVICE SYSTEMS REDWOOD CITY, Calif. - February 7, 1995-NeXT Computer, Inc. announced today that MCI has selected its object-oriented software, NEXTSTEP, for the development and delivery of custom applications for MCI's New Friends & Family program. Introduced in January, New Friends & Family offers customers who spend just $10 a month 25% savings on all domestic direct-dialed calls, and 50% savings to other Friends & Family customers in their Calling Circle. To further streamline and improve its customer service applications, MCI has placed a multi-million dollar order for NeXT products, including the advanced PDO (Portable Distributed Objects) and Enterprise Object Framework, which will help advance the company's specialized customer service stations. "We are excited to work with a leading telecommunications innovator like MCI," said Steven P. Jobs, Chairman and CEO of NeXT Computer, Inc. "MCI's speed-to-market and track record with Friends & Family, 1-800-COLLECT and Friends & Family Connections is unmatched, and we look forward to helping them bring more advanced products like these to market even faster. MCI's commitment to our technology is another step in the marketplace acceptance of object technology in general," Jobs added. "We believe in NeXT's object technology, because it speeds our development cycles, keeping us ahead of the competitive curve, and significantly improves our time-to-market with new products and services," said Jim Folk, Vice President of Information Technology for MCI Consumer Markets. "We selected NeXT technology because NEXTSTEP/OpenStep is a powerful object-oriented development environment that allows us to build applications in shorter timeframes and spend more time focusing on customer needs rather than in the lab." MCI MCI, headquartered in Washington, D.C., has expanded from its core long distance business to become the world's third-largest carrier of international calling and a premier provider of data communications over the vast Internet computer network. With annual revenue of more than $13.3 billion, the company today provides a wide array of consumer and business long distance and local services, data and video communications, online information, electronic mail, network management services and communications software. NeXT Computer, Inc. NeXT develops and markets the award-winning NEXTSTEP object-oriented software for industry-standard computer architectures. Customers use NEXTSTEP's advanced object environment to rapidly develop and deploy custom, enterprise-wide, client/server applications. NeXT is headquartered in Redwood City, California, and has offices in North America, London, Paris, Munich and Tokyo. # # # # NeXT, the NeXT logo, OpenStep and NEXTSTEP are trademarks or registered trademarks of NeXT Computer, Inc.

Currently, SNET (00088), the B-side carrier serves all of CT (it is the only company to do so, or will be after its agressive expansion into Litchfield County), as well as the Springfield, Mass area, up I-91 into Franklin County, and all the way to the Vermont line. Bell Atlantic/Metro Mobile, the A-side carrier, which is owned by the Mid Atlantic B-side carrier operating in NJ, PA, DE, VA, DC, MD, DE, and part of West Virginia (?), operates in all Connecticut counties except Litchfield, and in Rhode Island, Southestern Mass (e.g., south of I-495), Springfield Mass (but NOT Franklin), and the US-7/Berkshire region. Since Bell Atlantic (BAMS) and NYNEX plan to merge their services, (which hopefully will not drain revenues from BAMS's outstanding B-side Mid-Atlantic service), they need to shed their properties in RI and Mass which overlap. In an unusual, but logical move, NYNEX will be selling off its entire Rhode Island/Southeastern Mass system (00028), as well as it's Berkshire/Pittsfield, MA system (a woefully inadequate system) to SNET. That is, in EVERY market where the BAMS/Metro Mobile A-side system would have operated against a BAMS/NYNEX system, NYNEX has opted to sell its properties to SNET. SNET will now have a coverage area greater than Metro Mobile's, as it will include all of Litchfield County (which BAMS/Metro Mobile does not have the license for, and where it can offer services which MM/McCaw is prohibited from offering), and Franklin County Mass. It will also include all the NYNEX-B systems where Metro Mobile currently operates. Currently, NYNEX/MA-RI customers get toll-free calling between both states (or at least Mass to RI does if their literature is correct). How this will affect the current billing regime between the two states is unclear, but normally, B-side carriers can not carry Inter-Lata traffic without a waiver. I assume NYNEX received a waiver for this long ago; I do not know if the waiver will allow NYNEX/MA <-> SNET/RI calling in the same manner. (The A side does not offer toll-free MA-RI calling, so this isn't a terribly big issue, yet it is one of the advantages a NYNEX customer used to have over a Cell One/Boston or a Metro Mobile/RI customer.) Additionally, with SNET's "no roam charge" program(s), as well as those of NYNEX (and I assume shortly BAMS), Metro Mobile, always one to assert a roam charge when they can and which currently has some of the highest roaming rates in New England and New York, will likely be forced to lower these rates to be more competitive with a unified and roam-charge free B-side roaming system from Virginia to Maine. Currently, Metro Mobile/CT customer pay from $.60 to $.99 cents per minute to roam in NY, and MM/RI customers pay $3 day/$.99 per minute. CO/Boston customers pay $.44 peak/$.29 off-peak (plus the $2 roam-coordinator monthly beer charge :( ) in NY and New England, and NYNEX customers pay between $.50 to $.59 cents, and SNET customers pay between $.60 and $.75 cents. Metro Mobile will need to come down to match its "A" side partners as well as it's B-side "competitors". Anyhow, that's the news for now!

Go Communications is based in the Washington DC area. > 3) GO claim to be introducing GSM as CDMA looks unlikely to roll out > in the near future. What do other people think? No one technology will dominate, especially in the 10Mhz bands. The Federal Communications Commission will not dictate a specific technology standard that must be used by the industry. In fact, the FCC has embraced 7 common air interfaces and 2 signalling protocols. I do believe CDMA and PCS1900 will be the common air interface of choice for the 30 Mhz licenses or the A, B & C bands, while virtually all 7 common air interfaces will be utilized by the winners of the 10Mhz licenses or the D, E, and F bands. In addition, I believe winners of PCS licenses with exisiting cellular networks are likely to lean toward IS-41 compatible technology such as upbanded versions of IS-95 CDMA and IS-136 TDMA, while those without legacy networks will lean toward GSM MAP compatible technology such as PCS1900. See Technology Preference Score Card below. CDMA service availability (1) AirTouch already has "friendly users" on their CDMA network in San Fernando and is on target for commercial roll-out in June followed by coverage of entire LA region be year end (2) US West New Vector is on target for pre-commercial service in the entire Puget Sound Area by mid-'95. In addition to Seattle, the Puget Sound region extends to Bellingham to the North, Olympia to the South and the Cascade Mountain range to the East. Thus, US West will be available able to offer digital service virtually everywhere it can offer analog.

A new customer service, developed by Stentor Resource Centre Inc. (SRCI), has created another revenue generating opportunity for Bell and the other Stentor owner companies. Automated Directory Assistance Call Completion (ADACC) gives local directory assistance callers the option of having their calls automatically completed to the requested number for a 35-cent charge. It is now available in 905, 519, 705, and 416 area codes. This month it will be rolled out in area code 613 and in March, 807. Says project prime Sheila Philion: "Only a portion of local directory assistance requests are chargeable. With this value-added service, we've provided the Stentor owner companies (SOCs) with a vehicle that helps increase revenue potential associated with local directory assistance." Sheila says SRCI worked closely with Bell Sygma through every step of the project. Bell Sygma worked on the technical and operational requirements of the project, ensuring departments affected by the new system made all the necessary changes to allow for a smooth implementation. Says Bell Sygma team leader Art Brewer, "Bell Sygma overcame technical hurdles to get the technology delivered on time." "What I like about it is that it hits the customer right at the decision-making point. We know there's a strong likelihood that they will choose to use the call completion service. We're offering them an easier option that dialing the requested number themselves," says Janet Garrod of Bell's Consumer Market Management. The service has two billing options. The 'sent paid' option carries a 35-cent fee for each completed call. The 'alternative billing' plan adds an additional 75 cents to have the call charged to a Calling Card[tm], collect or third number.

Northern was approached by Hermes, a joint venture of U.S.-based Global Telesystems Group (GTS) and a consortium of 11 European railway companies, to submit a bid for the first stage of the planned network which will compete with the national carriers of France, Germany, Britain, etc. GTS is aiming to attract big international corporations which complain that the national carriers of Europe cannot meet their needs for "seamless" communications outside their national borders.

He has been charged with interstate transmission of a threat, a federal crime which carries a penalty of five years in prison on conviction. Mr. Baker published three stories in December on Internet in alt.sex.stories. One of the stories dealt with raping a female classmate after breaking into her home. He described the woman as 'shaking with terror' while several men beat, torture and sexually abuse her. Baker, whose home and parents are in Boardman, Ohio also exchanged messages with a man from Ontario in which he said, "Just thinking about it isn't enough, I need to do it." Federal authorities said the item published on the Internet became a threat and not just a fictional story when Baker identified his classmate by name. Baker was arrested last Thursday in Ann Arbor and taken to the federal correctional center in Detroit pending trial. Although Baker admits writing the story, he claims he meant nothing by it. He insisted the story was fictional and not intended as a threat. His attorney David Cahill said, "Jake is obviously sorry that he did this; he had no idea she would ever find out." The victim found out after University of Michigan authorities were alerted by an alumnus of the school who regularly reads Usenet and the various alt.sex groups. He notified the school and they in turn notified the subject of the article Baker had written. On Friday, Baker was taken before United States Magistrate Thomas Carlson for a bond hearing. After reviewing the matter, Magistrate Carlson refused to set bond. He stated that Baker must be considered very disturbed and a danger to the community; thus he will be held in prison pending his trial. As he was being led away, Baker insisted this was nothing more than 'a violation of my First Amendment rights and probably several other of my rights as well.' To protect the subject of the threat from further harassment she was not identified by authorities, who also asked the news media to not identify her. It must be remembered that in the United States, our consititution requires a presumption of innocence on the part of Jake Baker until proven otherwise to the satisfaction of a judge or jury in a court of law.

The relative in the other state is still there, but his phone number gets the message that the line has been disconnected, and not further information is available. I doubt that he wants to block my calls. Calling "Information" reveals that the name is not listed. But I know from others that he's still there. Question: can call blocking be limited to one or more specific numbers? From a specific area code? From a specific state? Thanks for the information. Bob Perkins bobp@netcom.com [TELECOM Digest Editor's Note: If there were unusual or esoteric kinds of special blocking in place then you would not get a recorded announcement that the number was disconnected. Yes, there are certain kinds of special blocks available. But if, for example, he was using Call Screening to specifically avoid your call, then the announcement would say 'is not taking calls at this time'. If he was blocking calls with blocked caller-id, (should you be doing that), then a recording would so indicate. I think it may be something you have not thought about: he may have had his number changed for whatever reason, and specifically had no referral given to it by people calling the old number. If the new number is non-published, then he would not be shown at that address, regardless of what you know or have found out from others, etc. Have you thought about that?

Under the MFJ, LECs were compelled to sell access, particularly switched access, to all carriers at the same rates. Since 1994, LECs can legally offer discounts and equivalent arrangements that reflect the underlying economies of access service provisioning. The net effect has been to favor AT&T with its economies of scale and disadvantage other carriers and resellers. How can regional facility based carriers and resellers overcome this cost disadvantage? 1. Develop and exploit economies of scale where possible. 2. Where these cannot be developed, use other carriers and competitive access providers who act as access aggregators to at least partially achieve economies of scale. If these strategies are not successful in bringing access costs down to a reasonable level, switched based resellers in particular, must determine if their approach to their marketplace is competitively viable. If it is not, then the firms must determine if a migration to switchless resale or service specialization are appropriate responses. Before the firm can choose the appropriate strategy or mix of strategies, it must understand its current and projected traffic patterns. The firm should construct a current and projected traffic matrix for all US end offices and international termination areas. Using the LEC tariffs and projected network backbone costs, the firm should identify for US end offices where direct transport makes economic sense given the current LEC tariffs. Obviously many end offices will have such a small amount to traffic that they can be assumed to be served by common transport at this stage of the analysis. This analysis yields a baseline cost against which to compare alternatives as well as identifying those end offices and LATAs where the firm could achieve economies of scale. The next step in the analysis is to identify ways to exploit the identified economies of scale and to shift marginal end offices onto direct transport through increased traffic. The firm can increase traffic in a particular end office in two ways. 1a. Increase the amount of traffic that its customer base generates at the end office. The firm can target through marketing efforts, customers who generate substantial amounts of traffic at the end offices and can offer discounts, that is share the economies of scale for those identified end offices, with customers. Many firms may be unable to realize economies of scale with this strategy. 1b. Make arrangements with other firms who cannot achieve economies of scale at specific end offices to carry their traffic. In many cases, part of the arrangement would be to offer to the other firm traffic to their high volume end offices. For example, a Northeastern based regional carrier or switch based reseller would want to partner with a Southeastern based regional carrier or reseller. The two firms would swap traffic so that the Northeastern based firm would originate and terminate Atlanta traffic through the Southeastern firm. The Southeastern firm would originate and terminate New York City traffic through the Northeastern firm. These arrangements would increase the opportunities for both firms to achieve economies of scale. The key is to identify good traffic matches and to have available cost effective connectivity between the two firms. The second strategic approach is to use access aggregators. ICG, MFS, and TCG, among others, offer alternative arrangements to the LECs for access in selected areas. They may replace the access tandems or offer an alternative to common and /or direct transport. In either case, they offer a cost reduction compared to the LEC for selected LATAs and/or end offices. This approach can be supplemented by the traditional use of WATS type services for termination coverage of areas with small amounts of traffic. While I have concentrated on the US, similar arrangements should be worked out where regulations permit for international traffic. US firms may find that partnering with a Canadian counterpart would enable both firms to lower overall access costs in their respective countries. Two or more US firms could split the cost of a private line group where regulations allow and the cost reduction would be attractive. While both strategies appear to be attractive, only the first, building economies of scale in particular end offices and LATAs, will generate sustainable cost differentiation. The second strategy of using aggregators is open to all carriers and depends primarily on access to cheap long haul bandwidth and negotiating skills. As the firm increases the total traffic at a particular end office, it becomes a more attractive partner to other firms. This form of partnering may well create opportunities for additional business relationships, particularly since an exchange of traffic would be involved.

Let me offer a few thoughts on this subject. Consider a company that provides communications services to people. It allows them to send and receive messages -- anonymously -- to each other. Some people use it to socialize. Some people use it to conduct business. Some people use it to talk about profound subjects; others use it to discuss things that are not profound. Some use it to help others; others use it to receive help for their problems. And some users abuse it and use it to harass people or to send child pornography. Should we demand that the company go out of business? Or rather, should we complain to the company itself when abuse happens? Well, there already is such a company. It is your local telephone company. Your post-office also does this. Yes, you can use the phone company anonymously -- just call from a pay phone. And you can use the post office anonymously, by not using a return address. Anon.penet.fi is like both the phone company and the post office. It is a common carrier which carries communications without examining the content of each message -- indeed, we would be very unhappy if the phone company listened to our phone calls, or the post office opened our letters, to determine the morality of the content of our communications. It doesn't snoop on us -- neither do Bell Atlantic or the United States Postal Service. And some users use anon.penet.fi for immoral purposes -- just as some people use Bell Atlantic for immoral purposes, and some people use the United States Postal Service for immoral purposes. That doesn't mean that we should eliminate Bell Atlantic or the postal service. Most people would not even call for the elimination of pay phones or delivery of mail without return addresses. Anon.penet.fi is also like the phone company service, Per Call Number Blocking. In some areas the phone company offers a service called Caller-ID. For readers unfamiliar with Caller-ID, let me just tell you that it tells people who's calling them. Caller-ID is similar to the return address on an envelope, or the From: header of a mail message. The phone company in many areas also allows people to press *67 or dial 1167 to suppress the caller-ID, so that their telephone number won't appear on the recipient's caller-ID display; this is called Per Call Number Blocking. It serves the same purpose as anon.penet.fi. Both of them suppress the identification information in a message. Yet, the government in some states *mandates* that Per Call Number Blocking be available. Apparently a lot of people feel that there is a privacy issue, and so they want the service. Anon.penet.fi also is like sending mail without a return address. Now there isn't, to the best of my knowledge, a large movement to prohibit delivery of mail without return addresses, is there? There is a possible compromise. The owner of anon.penet.fi indicates that he does not allow posting to all newsgroups. He could further restrict posting so that people would only post to legitimate newsgroups, much as the telephone company might cut of the phone service of a company that repeatedly uses its phone service for illegal purposes. And if you ever receive harassing mail through anon.penet.fi, just send mail to julf@penet.fi, just as you would call the telephone company if people made harassing phone calls. Anon.penet.fi is a useful service. It is available to many people with diverse needs. Sometimes people need to communicate anonymously, and anon.penet.fi allows people to do just that. Would you really want to eliminate the phone company or the postal service? [TELECOM Digest Editor's Note: There are some fundamental differences between telco, postal and anonymous email services. Your analogies are not quite correct. In the case of postal and telco, we do not supply them with our identity then ask them to keep it secret. We simply present the traffic in secret, using the letter with no return address or the call from the pay phone. In other words, when telco or postal note the anonymous nature of the traffic, the traffic is *already in their network*, and the transport already paid for by virture of the stamp on the envelope or the coin which was deposited in the collection box. They've no real choice but to handle the traffic at that point. The difference where anonymous remailers is concerned -- and I was one going back to the 'olden days' when people wrote letters on actual paper with actual pens -- is the traffic is considered delivered when it reaches the remail agent; he in turn then promises to put the traffic back out again, and protect your identity in the process. He has the option of doing that or not doing it; he can refuse your traffic if he does not want to handle it anonymously. Unlike the corner postal box where you drop things, or the payphone on the corner, the sole purpose of a remailer is to provide anomynity. Therein are some differences. Now, should we support a service whose purpose is merely to feed anonymous traffic into a network? *As long as he obeys the law and plays by the rules, yes.* The same thing could be said about 900-STOPPER, that attorney (I think in California) who allows and even encourages anonymous telephone calls through his switch. The rules where 'conventional' or 'traditional' traffic are concerned have always said you are ultimatly responsible for the uses made of your instruments. The rules have said if you deposit something in the United States mails -- or cause someone else to deposit something in the mail; i.e. you telephone a company fraudulently and they send you a credit card in the mail, you *caused them* to use the mail -- for the purpose of committing fraud, then you are criminally liable. It makes no difference if you simply have an agency relationship or not as long as you knew or should have known the uses being made of your service. Now, suppose I send you a pound of cocaine in the mail. I put it in the mailbox, a half dozen postal workers handle the package and you accept it when it arrives. I get caught and you get caught. We both get punished. Why don't the six postal workers in the middle -- since they were also in possession of an illegal substance -- get punished? The answer is quite simply, they had no way of knowing what they were handling. People who have no way of knowing what they are handling are called 'common carriers'. The postal service is a common carrier, as is telco, Federal Express and similar. They have to take all business which comes their way, and it is obvious from the volume of business they receive they would have no knowledge of the illegality or impropriety of any one segment of that traffic. In exchange, the trade off is that common carriers have to keep records of their traffic. The postal service is an exception to this, and that could be a story in itself, but the general rule is, common carriers have to retain, for a reasonable period of time records of their inbound and outbound, to be produced on request as part of an investigation, etc. The attorney who runs 900-STOPPER keeps those records; I don't care what he claims to the contrary. You think for a minute he is about to go to the penitentiary for your sins? Now he may -- probably does -- as a matter of course make those records very hard to obtain; you probably have to sue him and go through lots of hassles. In effect, his service provides a buffer of privacy for his clients, but bear in mind, there is recourse when it gets to that point if it ever does. When I operated my (old fashioned paper and pen, letter writing) remail service back in the 1970's, I required everyone who wanted to receive mail via my office to fill out postal form 1534 (authorization to deliver mail to an agent). And I had all kinds of shysters and con artists willing to pay me money each month to use my address as a mail drop. I used to get all these guys who wanted to advertise in (or answer ads in) 'adult magazines'. They never admitted as such to me; it was always this rap about how they were traveling salesmen needing a reliable place to have their mail held. What they meant was they did not want those 'swinger club' magazines going to their house in the mail where their wife would see it. And of course there were privacy considerations; they did not want to advertise in a publication like that giving their own street address. They'd rather the creeps and perverts showed up at my office door instead. That's cool, just pay me $$, and fill out this form for the post office please. I also had customers who only used me for outbound mail; they saw some benefit in having a Chicago postal cancellation on their letter instead of one from wherever they really were located. ("he must be in Chicago, I got a letter he sent me from there just last week, but he did not give me an address to write back to him ..."). I ran ads in {The National Enquirer}, {The World Weekly News} and other papers. A simple two line ad which said 'Remails from Chicago, $1 each, PO Box xxxx, Chicago, IL 60690'. People who knew what it meant knew what it meant ... those who didn't went on to read some other ads. Every day at the post office I would stand at the counter and open the mail. The dollar bills would go in my pocket and the sealed envelope addressed elsewhere which had been stuffed inside a larger envelope and sent to me went in the nearby mailbox. That simple. But for those who used my address as their drop, they had to sign a form sent to the Post Office Department of Mailing Requirements. When the Postal Inspectors would come to see me -- once a month or so on average, I would pull out my copy of the 1534 form for the client in particular, photocopy it for them and they'd be on their way after thanking me. Then I would send my client a note saying there had been a post office inquiry into his activities. I stayed out of it. The Postal Inspectors love doing doing business with the remail agents because there is none of the hassle of bothering with search warrants and all that. Its like the Federal Bureau of Investigation and that STOPPER attorney guy. They wish there were more of him and fewer telcos to have to deal with. The telcos come up with all the foolishness of requiring a subpoena and a warrant. He and the FBI guys probably go to the coffee shop downstairs and they buy his lunch while he talks about everything he knows. Now here comes the connection to anon.penet.fi. First of all, for me personally, I would not trust them. That's just me. But then, I know a little about sendmail and SMTP (sendmail transfer protocol) and how to make up my own fraudulent 'From ' lines if I were so disposed, so I may be prejudiced. They may be perfectly honest for all I know, and let's give them the benefit of the doubt and say they are. I have no reason to think otherwise, but I would still be very reluctant to originate some of the stuff I have seen come from there. Its another way of saying that anyone who thinks that the private one-on-one chat areas of America OnLine and Compuserve are *really* private -- that the midnight shift operator dudes in the machine room are not sitting there getting a few thrills of their own from time to time from what they read on their tubes -- is a fool. In any 'anonymous' networking, there are people who know what is going on, what was said and who said it, etc. So use any of those services at your own risk; anon.penet.fi might be perfectly fine, but you need to know the agent involved and trust him to throw up a few barricades as needed to make it harder -- its never impossible -- for you to be found out. Where the hangup comes is the agent can't have it both ways: either he is (1) responsible for his traffic and bears the consequences of it or (2) he is not responsible; is a common carrier and has records available for others to examine. If (2) does not apply, then go back to (1). ... Because by definition .fi is not in the USA, it gets a little harder to track things down, but they can be tracked down. If enough sites in the USA are pressured by their university or corporate owners or whatever to reject traffic from anon.penet.fi, then you will see some changes. I'd say let him and his clients do their thing; if no one will *receive* their mail or news, it will soon become pointless for them to *send* it. And sendmail can be hacked to refuse mail from a given site or send it straight to /dev/null, the same as telephone calls from blocked id's can be refused and mail in your box with no return address can be tossed out unopened or handed back to the carrier marked 'refused'.

Randolph U Franklin) Subject: Phones in Jail Date: 15 Feb 1995 23:19:39 GMT Organization: ECSE Dept, Rensselaer Polytechnic Institute, Troy, NY, 12180 USA Reply-To: wrf@ecse.rpi.edu (Wm. Randolph U Franklin) Today's {Wall Street Journal} has a long page one story on phones in jail. It's a $1G business. They say that there are 1M prisoners, so that makes an average of $1K/yr/inmate! Although they avoided it in the past, the big three are getting in since the profits are so big. The kickbacks, err commissions, to the jailers can be in the $millions. To pay for them, the phone companies may surcharge the calls even above the usual operator-assisted collect call rates. To lessen fraud, there may be lists of allowable or disallable numbers for calling. To give every prisoner a chance to call, the phone may disconnect after 15 minutes. (So why don't they just install more phones since the average phone in jail does $15K/yr?) Everything is monitored, from the numbers called by each inmate to recording the calls themselves. To get around the list of allowed numbers, some inmates call friends who forward the call to a disallowed number. AT&T tries to detect and block that. A collect call is automatically announced with fact that it's from a prison, the inmate's name and the prison name before the recipient has to decide whether to accept it. There was no mention of whether any inmates are running PPP or SLIP, or whether any inmates have cellular phones. :-) If these monopolies drive up the cost of calling much more, I foresee a market for illegal phone lines or cellular phones, supplied by the guards like they might supply any other contraband. Of course, it's a change from decades ago, when inmates were totally walled off from the world. Wm. Randolph Franklin, wrf@ecse.rpi.edu, (518) 276-6077; Fax: -6261 ECSE Dept., 6026 JEC, Rensselaer Polytechnic Inst, Troy NY, 12180 USA [TELECOM Digest Editor's Note: AT&T was staying out of the corrections industry business for quite a while because of the high rate of fraud. According to the WSJ article quoted, they are now rethinking their position on this. Corrections is a big market; lots of money to be made in all sorts of angles there. When I was in 6th grade at Lincoln Elementary School, a policeman known as Officer Friendly came to our class. The purpose of his visit was to tell us that he would like nothing better than to see the day come when there was no need for police officers anywhere, because everyone obeyed the law, as he was anticipating we would do. At the time, there were about nine hundred inmates in Cook County Jail, and about four hundred employees in the Cook County Sheriff's Department. (Now there are more than nine *thousand* inmates and about seven *thousand* employees of the Sheriff and the Circuit Court.) I held up my hand to ask a question, and was called on. I said, "There are four hundred employees of the Sheriff! Are you gonna stand there and say they all want to be put of out of work and on unemploy- ment?" He gave me the funniest look ... The sad fact is there are lots of people in the corrections industry with a strong vested interest in keeping the status quo. You don't *really* think they want the extremely high rate of violent crime in the USA to drop anytime soon do you? You don't *really* think they want to end the war on drugs do you? Yes, things have changed since long ago when inmates were totally out of society. Aside from no more James Cagney prison movies (inmates bang their cups on the table and start a riot; Cagney lays dying and makes his final confession to the Catholic priest (Father O'Something; what actor was that?) ... even the prisons don't look like prisons any more. Downtown with a friend one day a few years ago, we have lunch on the corner of Van Buren and Clark Street; she observes this nice building across the street -- a big highrise which looks like a modern office building, or perhaps a very nice apartment complex. After lunch, I had a couple quick phone calls to make and walk across the street, into the lobby of the building and use the payphone. She comes with me and stands there in the nicely furnished lobby. A receptionist is there at a desk; potted plants and sofas are around. I make my phone calls and we leave. On the way out she comments what a nice place it is; is it the corporate headquarters for some large company? No, I tell her ... its a federal prison. Haven't you ever been in one before? Her eyes grow big like saucers. Across the street is a Dunkin Doughnuts place; a bunch of guys sitting in there drinking coffee and passing time. They are prisoners who are let out during the day for whatever reason waiting until the last possible minute before they are due to go back up the street and into the prison and their dormitory for the night. I'm not saying I would like to live in one, but they are much different -- at the federal level at least -- than the old days.

Carlson Subject: BA Files Waiver to Prevent Higher ISDN Costs Forwarded to the Digest FYI. (No, that's not 'For Your Insomnia' PAT] ---------- Forwarded message ---------- Date: Wed, 15 Feb 95 13:23:21 GMT From: Bell Atlantic To: Multiple recipients of list Subject: BA Files Waiver to Prevent Higher ISDN Costs FOR IMMEDIATE RELEASE CONTACT: February 13, 1995 Michel Daley, (202) 392-1021 Bell Atlantic Files Waiver to Prevent ISDN Costs From Skyrocketing WASHINGTON, D.C.--In an effort to keep the Information Superhighway growing, Bell Atlantic late Friday asked the Federal Communications Commission (FCC) to set aside an order that would increase Integrated Services Digital Network (ISDN) prices dramatically. Bell Atlantic said it is ready to roll out ISDN service for residential customers, but the recent FCC ruling will increase the cost of the service 20 to 30 percent. Without a waiver, the company said, 60% of the potential ISDN consumer market will disappear. ISDN uses a single multi-channel, digital line to deliver voice, data and video services simultaneously. "We are shocked the FCC mandated a new price structure," said Edward D. Young, III, vice president and associate general counsel for Bell Atlantic. "We predict that, unless the commission adopts new rules: * not only will consumer demand for ISDN services drop, but also * new business demand will be reduced up to 35%, and * up to 25% of existing users--who have already made a substantial investment in ISDN equipment--will cancel their service. "The Commission's existing rules are not designed for services like ISDN," Young said. "Its ruling will kill the stampede to a valuable new service. ISDN can provide consumers with a high-speed, digital on-ramp to the Internet and to an array of information services." On Jan. 11, the FCC refused to allow NYNEX to restructure ISDN subscriber line charges (SLCs) to be more competitive with other carriers. The SLC is federally mandated and is set annually. The SLC is used to subsidize local telephone network costs, which helps to keep basic residential telephone service affordable. The Commission ruled that separate SLCs should be billed for each ISDN channel; ISDN lines have up to 24 channels. Several other carriers are billing SLCs per ISDN line, not channel. SLC amounts vary by jurisdiction, but are currently as high as $6.00 per line within Bell Atlantic's region. Bell Atlantic is a world leader in providing ISDN technology with over 91,400 ISDN lines in service. All common carriers must now comply with the FCC's rule interpretation in the NYNEX case unless they obtain a waiver. Bell Atlantic Corporation, based in Philadelphia, is the parent of companies which provide a full array of local exchange telecommunications services in New Jersey, Pennsylvania, Delaware, Maryland, Virginia, West Virginia and Washington, D.C. The corporation is at the forefront of developing a variety of new products, including video, entertainment and information services. Bell Atlantic also owns an interest in Telecom Corporation of New Zealand and is the parent of companies that provide business systems services for customer-based information technology throughout the U.S. and internationally. In addition, Bell Atlantic is the parent of one of the nation's largest cellular carriers and has an ownership position in cellular properties internationally, including Grupo Iusacell, S.A. de C.V., Mexico's largest independent cellular company. ------------------------------ From: smorrow@dotrisc.cfr.usf.edu (Steve Morrow) Subject: Call Accounting/Telemanagement Software Date: 16 Feb 1995 01:22:48 GMT Organization: University of South Florida Greetings all, I just wanted to solicit some opinions, comments, or words-of-wisdom about any call accounting or telemanagement software that you may be using or know of. We are currently using Orbitel Call Accounting from Teltronics, as well as "Telecommunications Information Management Systems" (TIMS) from LSU. Both are Informix-based systems which we are running under AIX 3.2.5 and Informix SE 5.0 on an RS/6000. We are outgrowing both rapidly, and are interested in systems that are more robust and current. Ideally, we would like to see something Informix (or even Oracle) based, where at a minimum, the front-end apps and reports are written in the RDBMS's tools and can be customized for our needs, and phone/extension/authcode data are stored in tables. It would be nice to see something which polls raw call data into tables also. Does this seem realistic? We've been approached by Matsch Systems (MicroFocus-based) and Sunbelt Business Computers (SunDial, Informix- based). Both _appear_ to offer nice packages, but these are only two of a 160 companies that provide telemanagement software (according to a vendor list I just got a hold of)!

Poe) Subject: Fax Modems and Voice Lines Date: 15 Feb 1995 22:46:34 GMT Organization: JHU/APL I have been trying to get a fax modem (internal, in a Mac Powerbook) to work at home, on a line shared with an answering machine and several voice sets (3). The feature that doesn't work is one the manufacturer calls "Silent Answer", where it allows other devices to pick up the phone, then listens in for fax ("CNG"?) tones. When it hears the fax tones, it is supposed to pick up the phone, causing the answering machine (for instance) to go offline. I have wasted a lot of time and false leads from the manufacturers trying to figure out what's wrong here. As near as I can tell, the modem simply can't hear the CNG tones when a handset or answering machine picks up (there are clues in the software response). One small clue in the owners manual suggests that equipment that injects noise in the line may cause CNG not to be recognized. So my question: Assuming this is the problem, is there a quick, off-the-shelf (cheap) fix? Do I put some sort of audio filter in line with the modem? I assume I need something specific to telecomm applications, since there are certain voltage conventions to be followed.

Personal Communicator Divison. Date: Wed, 15 Feb 1995 23:23:49 GMT Press Contacts: Cheryl Beck-Ruff Motorola 708/576-7150 Karen Magill Cunningham Communication, Inc. 617/494-8202 Motorola Announces Commercial Availability of Envoy(r) Wireless Communicator Envoy Device Available in Reseller Locations SCHAUMBURG, Illinois - February 14, 1995 - Motorola's Wireless Data Group today announced that the Envoy(r) Wireless Communicator, which began shipping in the U.S. to distributors in late December of 1994, is now available nationally in select reseller and distributor locations. The Envoy Wireless Communicator, which is based on General Magic's Magic Cap(tm) platform and Telescript(tm) communications language, is a portable communications tool for mobile professionals, which is extremely powerful yet simple to use. "Since we began shipping in December, industry response to the Envoy product has been tremendous and sales have been strong," said Rick Lane, general manager of the Wireless Data Group's Personal Communicator product organization. "The Envoy Wireless Communicator is changing the way mobile professionals communicate by allowing them to manage business from remote locations and dramatically increase their productivity." The Envoy Wireless Communicator is currently available at the following reseller and distributor locations (respective headquarters noted below): o Totally Wireless (San Jose, CA) o DCC Inc. (Minneapolis, MN) o PanaPacific (Campbell, CA) Distributor o Rockwell Computer (New York City, NY) o Oak Brook Computer Center (Oak Brook, IL) o Fourth Dimension Industries (Holbrook, NY) o PageCom (Dallas, TX) o J & R Computer (NewYork City, NY) o Dynatek Communications (Warminster, PA) Distributor o Verns Electronics (Boca Raton, FL) o Wireless Telecomm(tm), Inc./WTI (Aurora, CO) Motorola's Wireless Data Group works closely with select resellers, distributors, VARs, system integrators and specialty retailers that are interested in providing users with the highest-quality wireless solutions and support. Initially, Motorola will limit the number of organizations distributing the Envoy device and focus its efforts on ensuring maximum product sell-through and user satisfaction. Wireless Communicator Increases Productivity, Flexibility The Envoy Wireless Communicator allows mobile professionals to instantly access, communicate and organize information while on-the-go. Designed for both business and personal use, the Envoy Wireless Communicator integrates two-way nationwide wireless, wireline and infrared communications onto a single portable communications device. The Envoy Wireless Communicator is an all-in-one tool for those who need to stay in touch and organized while away from their desk. The Envoy device: o can send and receive messages to any of over 20 million e-mail enabled users. o communicates with millions of existing products and services including pagers, fax machines, desktop computers and on-line services. o helps manage life's complexities - tracks appointments, files name cards and captures expenses. Integrated Wireless Delivers Instant Access and Response The Envoy Wireless Communicator features a built-in two-way wireless packet data modem that allows users to send and receive messages and information at their convenience. The Envoy Wireless Communicator also includes a fax and data modem, allowing information to be communicated through any telephone network. Through its combination of wireless and wireline modems, in addition to infrared for local area communications, the Envoy product offers the most versatile communications capabilities on the market today. To augment its functionality, Motorola's Envoy Wireless Communicator also features two PCMCIA Type II slots that allow users to simultaneously operate third-party software applications and add memory to store more data. About the size of a paperback book and easily stored in a briefcase or purse, the Envoy Wireless Communicator weighs 1.7 lbs. and measures 7.6 x 5.8 x 1.2 inches. Complete Suite of Built-in Software The Envoy Wireless Communicator comes bundled with software to connect users to two communications services: AT&T PersonaLink(SM) Services; and RadioMail(tm), connected via the ARDIS(r) nationwide wireless data communications network. ARDIS services more than 90 percent of the business areas in the U.S., including 400 metropolitan areas, which encompass 10,700 cities and towns. AT&T PersonaLink AT&T PersonaLink Services is an electronic community where people can send and receive messages, gather news and information - even shop. PersonaLink is the first on-line service to incorporate (Telescript) electronic "intelligent assistants," which empower subscribers with unprecedented control over their communications. Subscribers can program the intelligent assistants to do tasks such as sort, prioritize and forward electronic mail to virtually any e-mail service, including the Internet. PersonaLink offers subscribers cost and convenience options with a robust on-line service that will fully integrate wireless and wireline communications. AT&T's PersonaLink wireless service, scheduled for introduction this year, will be a nationwide radio packet data service with automatic roaming, full end-to-end encryption (for enhanced security) and wireless access to the user's electronic mailbox. Also available during the second quarter will be AT&T Market Square(SM) plaza, an electronic shopping service offering products such as clothing, flowers, computer equipment and collectibles. RadioMail RadioMail allows wireless messages and information to reach Envoy communicators in all locations where ARDIS service is available. This service enables users to wirelessly communicate with a broad population of electronic mail users via the Internet and commercial public mail systems, delivering access to a global network of more than 20 million people. The Envoy Wireless Communicator also features built-in software which allows access to available services from America Online(r) and Official Airline Guides (OAG(r)) FlightLine(tm) Service. America Online allows users to receive stock quotes and communicate with electronic mail users. The OAG FlightLine Service offers air travelers direct access to timely flight information. The Envoy Wireless Communicator also comes with Intuit's Pocket Quicken(tm), an application that allows users to manage personal finances. Motorola is working with multiple independent software developers that have created a variety of applications and services for the Envoy communicator. More than 15 applications, ranging from spreadsheets to desktop connectivity kits, are available. Motorola and General Magic will continue to work with independent software developers to create more applications and services for the Envoy device. Pricing, Distribution and Availability Although pricing is ultimately the responsibility of the reseller, the street price of the Envoy device is likely to range from $1,000 to $1,500, depending upon the solution bundle users choose to purchase from the distribution channel. Accessories available for the Envoy communicator include carrying cases, a travel and a rapid charger, and replacement parts such as batteries, power adapter and stylus. Motorola makes it convenient for customers to purchase additional products and services through the Motorola Software and Accessories Catalog, packaged with each communicator. For general information about Motorola's wireless solutions and other Envoy communicator reseller locations, users can call the information and dealer locator number, 1-800-8WIRELESS. Motorola's address on the Internet's World Wide Web (WWW) is http://www.mot.com/ The Envoy device will be supported by Envoy communicator retailers as well as Motorola's HelpDesk. Family of Wireless Communicators Earlier this year at MacWorld Expo, Motorola also announced and shipped its Marco(r) Wireless Communicator in the U.S. Motorola's Marco device is based on Apple's Newton(r) operating platform. Both Envoy and Marco Wireless Communicators integrate computer and two-way wireless technologies into a new category of product and represent the industry's first family of wireless communicator solutions. Motorola's devices currently support the ARDIS wireless data network.

Little Rock, AR *** (501) 791-0124 What should of been a simple installation of a second line has turned into a an expensive nightmare. In November, 1994 we asked to have a second line installed on Dec. 1 as part of a promotion SWB was offering. They came an installed the line adding DLC to the outside of the house Finally around the latter part of January we get them back out to put both lines on one DLC so that the existing two pair wire could be used for both phones. Still no dialtone on our second line. I check the wiring and everything 'appears' to look ok. All pairs are wired to the jacks. Whomever installed the wiring originally was more than likely the phone company judging from the workmanship. (it 'LOOKED' great). Rather than ohm the wires which I didn't have time or interest in doing I called the phone company earlier this week to just have the second line disconnected siting a month and a half to install and not wishing to spend anymore time or money on a phone that I haven't been able to use. They tell me that we have 'In-line' wiring on our lines and that before turning the line out I should take advantage of this. So I did. The tech comes out the next day goes to my daughters room and leaves in five minutes telling my wife that it will be a $56.00 charge. The second line worked on her phone but, still no dialtone on the other three jacks in the house for the second line. I call today to complain a: about the $56 charge that we were not made aware of upfront, and b: that I still did not have a dialtone on any of my other jacks. They said that I needed 'special' jacks for two line phones. I explained that the jacks that were here all had the capability of handling two pair, and look just like what I would buy at Radio Snack. All they would say is I needed special jacks, and they would be glad to come out for an additional charge of $44.00 for the first 15 mins and $16.00 for every additional 15 mins and fix the phones. I explained to them that I put my ohm meter on the yellow and black wires coming out of the floor and I have no current at all on this pair even while the other line is ringing. (I'm no phone guy but, have been in computers/networking over 19 years professionally and know that there ought to be enough current when it's ringing coming down that line to knock loud enough to notice). Anyway, unwilling to pay an additional charge I told them to simply disconnect the line, after 2 1/2 months I'm tired of messing with it and to take all the 'extra' crap that they added to the house with it. ie ... old house and unique. And I wasn't happy about having something else stuck on the outside of it. They called back this evening. The tech said all he had to do was strip the wires and it worked. . I told them that I would check all the other jacks. Sure enough whomever had installed the jacks originally had put the wires on the post but had not stripped them. Ah problem solve I thought. Stripped wires and reconnect. *&$%() Still no dial tone on the second line, back out with the ohm meter. Still no reading across 'bare' yellow and 'bare' black wire with line ringing. No current, nada. This holds true on all three jacks. Now, the question is. I am an idiot and am missing something simple or should I be able to get some kind of reading off the wires? or both?. The tech assured me on the phone that I should get dialtone at all the jacks for the second line. What should I tell them when I talk to them Monday again? jim.wenzel@grapevine.lrk.ar.us The Ferret Bulletin Board System (501) 791-0124 North Little Rock, Arkansas [TELECOM Digest Editor's Note: I think you would be wise at this point to go back to the very beginning where the demarc is and the wires come into your house. Trace that second line from its starting point to the one place where it does appear and works correctly. At some point it branches off to serve the other three jacks and the wires are broken or disconnected and this may be a very obscure place. Don't keep jumping around the house with your ohm meter. Just go back to the very beginning and patiently work your way forward through your entire premises. If you cannot locate which wires are which at the point where they branch out, then put a sounder or noisemaker on the line at one of the jacks which does not work and go listen for that on all the pairs where they converge by the demarc. If you don't have anything else to use, take a small portable battery operated radio and hook the speaker connections to the dead pair in one of the boxes. Go to the demarc with a phone receiver and alligator clips and start prodding around until you hear your favorite radio station. Use logic and a process of elimination to unsort the wires and get the right ones in the right places. Forget Bell and their $56 charge.

When I couldn't find it in the menu, I also bailed with a *0. It seems that due to "Tariff Restrictions", call sequencing has been disabled in my area. The AT&T rep DID, however, offer to program my "Final Stop" number (which it seems is a manual effort by AT&T). Isn't "Final Stop" service call sequencing also?? When I gave her the number (which is my CellOne NY/NJ number, forwarded to Voice Mail), she asked, "Is that a cell phone, sir?". Nice database those people at AT&T have. ;-) She said it's not a problem, it's just that they "like to know." Also, it seems that once True 500 Voice Mail is enabled, the pager notification option will only work if your pager is reachable from an 800 number. I guess AT&T doesn't want to foot the bill for all those out-dials to pager companies all over the country. In this case, it looks like I'm going to keep my CellOne NY/NJ Voice Mail, since CellOne is only TOO happy to page me at my local 516 pager number. Stan (that's 1-500-442-0000 to you!) [TELECOM Digest Editor's Note: I did not bother to subscribe to their voicemail. I have voicemail in several places; more than enough to meet my needs. I just have the Reach List and Override capabilities. They never could explain why Call Sequencing is not available here; I think the whole thing is still sort of messy but they will gradually get it working. Sending out that postcard announcing the ability to call anywhere was sure a dumb thing to do though.

Apple Hails FCC Frequency Allocation for Data-PCS CUPERTINO, California -- February 15, 1995 -- The long-expected era of wireless computing was given a solid boost last week when all five FCC Commissioners unanimously voted to allocate 10 Megahertz of radio spectrum for low-power, wireless data communications, "Data- PCS." Apple initiated the FCC process that led to the decision, beginning with a Petition for Rulemaking in January, 1991. Apple's petition was endorsed throughout the computer industry and by numerous educational, business, and medical institutions and associations. Apple senior vice president David Nagel and vice president and general counsel Ed Stead led Apple's effort before the FCC and Congress in obtaining radio frequencies for Data-PCS. In light of last week's FCC decision, Nagel said that, "The FCC, under the leadership of Chairman Reed Hundt, has recognized the importance of wireless computing and, with this commitment of frequencies, has made possible new ways to learn, provide medical care, do research and conduct business." Stead added that, "This action gives U.S. computer companies a substantial edge in world markets; it will enable millions of students to connect to the growing online digital information world such as the Internet without costly installation or airtime charges, and makes possible a rich diversity of consumer, business, medical and institutional benefits." Before last week's action, the few radio bands available for wireless computing were overloaded with industrial transmitters or occupied by microwave stations; and, thus were unusable without massive relocation costs (estimated to be as much as $500 million) and ten to twelve years of band-clearing. The new frequency allocation for Data-PCS -- 2390 to 2400 MHz -- is shared only with ham radio operations, which are compatible with Data-PCS devices. As a result of the FCC's allocating the new band without further procedural or administrative delay, starting immediately, manufacturers can produce radio modems so educators and other users can set up their own wireless networks. The cost and complexity of wireless computing devices can be substantially reduced and their bandwidth (or data rate) can be significantly greater, allowing for such applications as multimedia.

Here is a message from Dr. Berryhill, a lawyer who filed the case, indicating that the Patent Office has granted the request and will reexamine the patent. Greg Aharonian Internet Patent News Service (for subscription info, send 'help' to patents@world.std.com ) (for prior art search services info, send 'prior' to patents@world.std.com ) (for WWW patent searching, try http://sunsite.unc.edu/patents/intropat.html ) ==================== On February 9, the Patent Office issued an order granting the request for reexamination of U.S. Patent No. 5,195,132. According to the order, "A substantial new question of patentability affecting claims 1-24 [all claims] of patent number 5,195,132 to Bowker et al. is raised by the request". It is expected that a notification of the reexamination, which has been assigned re-exam control number 90/003674, will be published in this week's Official Gazette. Accordingly, there will be approximately three more months during which any other citations of prior art will be entered into the patent file for consideration during reexamination. The Patent Office has given AT&T two months during which they may file a statement as to why reexamination should not be ordered. Such a statement would be unlikely, since it would then give the requester's an opportunity to reply. In the event that AT&T does not respond, it is expected that reexamination will be ordered shortly after the two month deadline, and that an Official Action rejecting all of the claims of this member of the "True Voice" patent family will be issued. ------------------------------ From: bei@dogface.austin.tx.us (Bob Izenberg) Subject: Bellcore ISDN Spec Phone Number?

The conference will be hosted by the Center for Tele-Information at DTU located in Lyngby just north of Copenhagen. This CFP is also available on the WWW as http://www.tdr.dk/~jnp/ifipin.html. Call For Papers =============== At the moment there are two major trends in Intelligent Networks (IN) development: o ITU and ETSI based IN o and long term development as undertaken by, for example, the TINA consortium and the European RACE and ACTS programmes. The present IN development, based on capability set technologies, is on the way to the network. The migration path from IN to, for example, TINA architectures are still under study. But there is a distinct move towards more open platforms for the functional entities, such as SSP, SCP, SDF, etc. supported with, for example, the core INAP protocol. At the same time a number of research projects are defining an IN architecture to be used in broadband networks as well as in present networks. The first demonstrations of these concepts are scheduled for '95. The integration of intelligence in broadband and mobile networks, and the way in which the service logic is distributed may shake industries. The aim of the the Working Conference is to collect state of the art contributions in the area of IN technology. Topics of interest include, but are not limited to: o Service Provider solutions on Service Creation and Management o Applications on Broadband and Mobile o Experimental systems and case studies o Performance issues o Long Term IN Architectures Papers should not exceed 12 pages including text and illustrations. Frontpage should contain authors' names, affiliations, address, phone, fax and e-mail address and an abstract. All submitted papers will be reviewed. Contributions must be send to: Osa Bennett Center for Tele-Information Technical University of Denmark Elektrovej, Building 371 DK-2800 Lyngby Denmark at the latest June 9 1995. Previous Conferences: The growing importance of Intelligent Networks for Teleoperators and Service Providers in a competitive market, stimulated IFIP TC-6 (Telecommunication Systems) to establish a task group on IN. The task group organised IN Workshops in 1993 and 1994 at the Lappeenranta University of Technology, Finland. Due to the success of these workshops the event is now proceeding as a Working Conference in 1995 in Copenhagen, Denmark and Conference in 1996 in Dallas, USA.

(Calling prices > within a state may vary.) When making several calls at once, press > "*R" between calls to return back to the menu. Woah! $1.05 for the first minute? That's completely different from what the AT&T rep told me last December when I was inquiring about 500 service. She was explaining all the different service levels, and mentioned that with the top one or two, I could get this Place-a-Call service. "Oh, you mean like a calling card?", I said. "No, much better than a calling card, because there will be no surcharge on the first minute of the call. The whole thing will be billed at the .25/.15 rate." I said that did sound interesting indeed, but wondered out loud why AT&T would seemingly undercut their own calling card rates so readily. "Well," she said, "I guess they reasoned that it would only take a smart user a moment or two to realize that they could achieve the same thing by forwarding their 500 number to the place they wanted to call, calling their own number, and then forwarding it back. They're just making the process easier, since you can do it anyway." As she was telling me this, a little voice in the back of my head was saying, "No, that just makes too much sense. It can't be true. It implies a level of sophistication on AT&T's part, combined with a respect for the intelligence of the customer, which are unknown in the industry." It seems the little voice was right. But will her alternate scenario work? The only objection I can see is that someone else may dial the 500 number while you're on the call, and they would be forwarded to the same destination as your call. But with a minimum cost of $1.05 per call, it could be worth getting a separate unpublished 500 number, and using it solely for beating the calling card surcharges. Come to think of it, an 800 number might be better for this use, as long as it could be follow-me forwarded toll free. Gary Novosielski GPN Consulting [TELECOM Digest Editor's Note: Some of their competition allows outcalls via 800, such as MyLine and Arch with no additional first minute charges. If you get a second 500 number exclusively for the purpose you describe, you must remember there will be monthly service fees on that which will offset some of the savings under your scheme. Their ill-fated postcard which went out in error -- outcalls are not available yet, no date when they will be, despite the postcard -- did mention the $1.05/95 rate for the first minute. Who knows, maybe that was wrong also. Unless you expect your 500 number to get a lot of traffic, I imagine you can get by with just one. Its unlikely a second call will come in just at the same moment. What you can do is set it up to forward your call as you describe then immediatly when you place your call and the other end answers, if there is a second phone line handy, you can use it to dial in 0-500 and take down the forwarding. It won't disturb your call in progress.

Through my on-going education at the University of Minnesota, Morris and my work experiences at U S WEST (summer intern) I have found that I am most interested in LAN/WAN technology and connectivity. I would enjoy designing, setting up, and administering a LAN/WAN. I'm an especially intrigued by the nation-wide (and worldwide) telecommunications infra- structure, and have put many hours into studying these areas. I am also a UNIX enthusiast and have been the SysAdmin for one of the UNIX boxes on campus for over a year. Currently I am in the third year at the U of M pursuing a degree in Computer Science. If any of you could suggest a course of action that I might take (after receiving my CS degree) I would be most pleased. Thank you. Mark Bentley A.K.A.

Of course, such a rationale would make sense only in the context of changing the dialing plan to allow *any* country to be dialed as just . But that idea won't fly unless we're also prepared to change our existing N11 numbers into something else (say, 1N11 or 0N11). The problem is that some international calls would have the same initial three digits as some very important N11 numbers (namely 911 and 411), and therefore timeouts would be required to disambiguate the two. This might not be such a big deal in the case of Directory Assistance (411) vs. Zurich, Switzerland (41-1-). But it certainly would be a problem for Emergency (911) vs. Delhi, India (91-11-). I don't think that anyone wants to add delays to the 911 system, and I also doubt that there will be much enthusiasm for changing the emergency number and then educating everyone about the new one.

Police have received calls on their emergency line and answered, only to hear additional buttons being pressed as the person continues dialing a complete number in India. When they can get the person's attention, the caller seems very confused about why he got the police instead of whoever he was calling. Obviously he forgot the '011' part, but police dispatchers on a busy night do not have a lot of patience to sit and explain that to the confused caller.

Here's the historical reality. AT&T wanted to be broken up. The original case was against Western Electric and AT&T's ownership thereof. WECo had an effective monopoly on public network manufacturing in the USA; with about 84% of the lines (AT&T's). All other manufacturers (GTE, ITT, Stromberg, etc.) had to fight for the remaining crumbs. The goverment sued to have AT&T divest Western Electric. AT&T countered by divesting the local telcos. The Reagan administration's Justice Department liked the idea and handed it to the Judge. He actually ameliorated some of its harsher terms; as originally set up, it was (IMHO) to be an out-and-out screw job on the to-be-divested local Bells. AT&T wanted rid of the Bells because everyone knew that computers and long distance were the profit items; local telcos received huge subsidies via the splifs. Of course not everything worked out as planned. AT&T's initial forays into the computer business were less than stellar, while the Bells have not all done so badly! I do however agere that the rules need reform nowadays; they're overly rigid and seem more designed for market allocation than for consumer protection. Cellular is just the most obvious, egregious weakness. Fred R.

But who are the startups > that are out to kill the PBX makers? A PBX consists of two parts: a switching fabric and a control processor. Most switches today have a switching fabric that is hardwired; the control processor does not need much power; the 68000 that you mention is a good choice. An 8080 would be enough, but has insufficient room for programs in its 64 KB address space. It is possible to build a switching fabric entirely of almost-standard computer hardware plus analog/digital conversion chips. The economics are definitely headed in that direction. The problem is that the program must ALWAYS be running, and the inexpensive personal computers do not have that kind of stability. I would expect that someone will soon put a small PBX on a PC plug-in card in the same way that people are now putting network hubs and even small routers on such cards. This will become especially attractive as stable multitasking systems take over from Windows and Mac-OS. Today, this is commonly done for keysystem-sized ISDN PBXs, which benefit from being able to install software updates via the PC disk drive.

Date: 15 Feb 1995 17:09:38 -0500 Organization: America Online, Inc. (1-800-827-6364) Reply-To: jeffb65582@aol.com (JeffB65582) PC's as PBXs? You've found one of my favorite subjects here. I'm the VP of Systems Development for a small switching system manufacturer that's been around for eleven years. In parallel with the development of our business, I have watched the development of the PC industry and been on the constant lookout for how we can benefit from PC technology in our product line. It's truly a good news / bad news story. PC's have attractiveness in that they supply enormous computing power at low cost. However, they also have many architectural limitations as well. If you want to use a PC for a PBX, you should consider some of the architectural limitations I'm talking about. Try these as examples: 1. Not enough card slots. A big PBX has hundreds of port card slots. My smallest PBX has forty (to support 288 ports). PBX port cards are generally much larger in surface area than PC ISA cards to support the many interfaces and high voltage spacing requirements. Don't forget that the port cards have to deal with the transient surges from multitudes of phone lines that all serve as "antennas" during every thunderstorm. 2. No ability for hot maintenance. Try adding a new card or replacing a card in your PC without turning it off and without interrupting its operation. Sure, you can pay technicians overtime to work after hours but that eats up the savings that drive the PC idea in the first place. 3. Inadequate power systems. Remember, the PBX has to power the ports, usually with -48VDC. Its important to keep the phones running all the time. Existing PC power supplies, voltages, backplanes, and connectors aren't up to it except in small cases. 4. PC technology is in a constant state of flux. Part of the PBX vendor's task is configuration management. Reliability partly stems from doing a good design, testing it, and then replicating it with identical copies. PC's change so rapidly that its very difficult to put them into a product that has a ten year plus service expectation. You need to have a continuous ongoing engineering process just to deal with PC design evolution. Try the desk top view point: How many PCs had your phone seen come and go from your desk top? What was the average PC cost? Convert that to dollars per year and see if you still think the PC will save money. 5. No hardware aid for software reliability. PBX systems do not have perfect software. They achieve high reliability through a combination of excellent software, testing, and certain hardware features designed to make the total combination have better reliability characteristics. Redundancy, load sharing, watch dog timers, and distributed intelligence, when properly applied, all contribute to this. If PC software vendors have a solution for this, they're keeping it well hidden. These are but a few examples of the problems we have faced trying to use PC technology in the switching business. Dealing with the customer requirements reflected above is a major ingredient to our survival in a market where many other start-up companies have vanished. Of course, it is said that PC's can evolve to meet any objections I raise for use at telephone equipment. You must decide, however, when you cross over the line where the "PC" you started with has changed so much that it can no longer be recognized as a "PC". It may surprise some to hear that PBX vendors are not ignorant of PC developments. Over the last several years, PC technology has had a significant impact on PBX design. Processors, chip sets, PCMCIA memory, and many other components that were pioneered by the PC industry have found their way into modern PBX design where they save cost and do not compromise reliability. If you look "under the hood" of some PBX's, you might identify what you see as an evolved PC. Perhaps they only reason they are not considered to be PCs is because they "don't do windows". These comments would be incomplete if I didn't mention that there are some products on the market that identify themselves as PC based PBX systems. In each case, they have found a niche where they try to work around the issues raised above with a combination of modified PC hardware and external equipment. Two systems I'm familiar with can not support ground start, direct inward dial, and T1 trunk connections. They use external devices to convert the phone trunks to loop start lines they support. Some also use external power supplies yielding a collection of boxes to support the PBX function. The PC technology disk storage gives them good capabilities in voice messaging and the VGA display can yield a single nice attendant display. Some of the other points I made above are simply not addressed in these products and time will tell what portion of the small line size market can accept the compromises. I applaud their pioneering approach while at the same time I know that their products can not meet many of the customer bid specs that I see. One of the neat things about the telecommunications marketplace is the enormous room for different ideas and products. If there is a significant class of customers that accept these systems, it should become apparent in the next year or two. My own company uses PCs as data collectors and report processors for PBX based automatic call distributors. If these PCs go down, the phone switch continues to process calls. We also have a blended architecture ACD (automatic call distributor) product which uses an industrial PC coupled with existing switching equipment shelves (of our own design) to produce an advanced call center system some of the best features of both. This product provides ACD call functionality, voice messaging, IVR, and fax server functions integrated together. These systems focus the PC into the areas where it is strong and cost effective while allowing the benefits of the existing switch equipment to be retained. If necessary, the entire PC can be duplicated in a redundant configuration. We continue to look for and innovate with PC technology. But the PC technology needs to blend with many other elements to make a good telecommunications system. I tend to agree with "Chazworth@aol.com" that the PBX vendors of today will still be the providers tomorrow no matter what the technology evolves to. Users still need the service & maintenance expertise of these. When something breaks, they NEED it fixed with on-site persons very quickly and the PC industry has done little to address this.
