In the early days of the IBM phone network, this was the case between
multiple PBX locations in a large site (I'm familiar with
Poughkeepsie; other sites were probably similar).
There were a multitude of dialling prefixes to go from one local
location to another.

Yes.
Before a unified "dial 8" IBM internal network, there were a multitude
of codes for different locations. Some of them were of the "let your
fingers find the way" where you dialled a code for one location, and
then its code for an associated location.
After the dial 8 network was put in place, you dialed 8 + 3 digits for
location + 4 digits extension.

I had a couple of experiences trying to get from an outside call to a
remote location, it depended on the whim of the operator. On one
occasion, I was able to get a person to agree to call the remote
extension and deliver a message.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead. -Request for Comments: 1925 IOOF
[TELECOM Digest Editor's Note: The Stanotel network of Standard Oil
Company was really something in that regard, but the biggest I have
ever seen -- with a seven digit dial in number from the 'outside
world' and absolutely unprotected; no password required -- was the
United Airlines phone system, _Unitel_ based out of the airline's
corporate offices in Elk Grove, Illinois. They had eighty or ninety
tie lines (all dialed into beginning with '1' followed by two more
digits; for example, '147' was the tie line code you would dial to
reach the San Francisco airport. Dial 147 (or 176 for Ohare as
another example), you then heard another dial tone from the centrex
in the distant city. At that point, do what you want, but most of
_those_ centrexes also had tie lines of their own going to still
smaller airports. You got USA WATS lines (band 6 as I recall) by
dialing 181 off of the Elk Grove system. One of the tie lines served
the airport in Seattle, WA, but then from that distant centrex there
was another three digit code which got you the centrex at Boeing
Aircraft, mainly because Boeing was/is a big supplier to United
Airlines. Another three digit tie-line code off of the Seattle
airport centrex (reached from Elk Grove if I recall correctly with
'124') got you _their_ WATS lines from Seattle, still another code
(from the Seattle centrex) got you access to Canadian WATS. If you
let your fingers do the walking, you discovered all sorts of very
interesting three digit (or less) tie-codes and/or outside lines
through those distant centrexes, all directly dialable with their
own tie-codes out of Elk Grove.
This was back in the days when everything in northern Illinois was
312, and subscribers could have an 'unlimited call pak' as they
were known for about $25 per month. All reachable and unpassworded
on 312-954-xxxx (a call-extender for the use of people working from
home rather than the UAL office complex.) The United Airlines 'Unitel'
system was a _m a s s i v e_ thing. One of the tie lines even went
to the United States Department of Aviation Administration, but when
you got to _that_ switchboard you could not get the '9' level or any
of its tie-lines or WATS lines, etc. But you sure could get out to
other points from most of the connecting switchboards/centrexes, etc.

WIRELESS POWERS $34 BILLION YEAR IN TELECOM: "A new report from
Statistics Canada says the telecom services industry took in $34
billion last year, up 4.1% from 2003. The growth came entirely in
wireless, where revenue rose 17.5%, subscribers increased 12.7%, and
revenue per subscriber increased 3.0%.
** Wireline still produces two-thirds of industry revenue,
but its contribution fell by 0.6%, the third consecutive
annual decline. The number of wireline phones in service
has been falling for 12 quarters: 4Q 2004 was 1.2% below
4Q 2003.
** At the end of 2004 there were 46.5 mobile phones per 100
inhabitants, up five points from 2003.
** Overall operating profits were $7.2 billion in 2004,
compared to $6.2 billion the previous year. Wireless was
significantly more profitable than wireline.
** Capital spending, which increased in both wireline and
wireless, totaled $5.5 billion in 2004, a 12.2% rise. This
was the first increase since capital spending peaked at
$7.7 billion in 2001.

(See Telecom Update #433, 461, 470)
** The report calls spam "a significant social and economic
issue, a drain on the business and personal productivity
of Canadians, and a cloak for criminal activity." Spam now

U.S. VoIP PROVIDERS MUST PROVIDE E911 BY FALL: By the end of
September, all U.S. VoIP phone services that interconnect with the
public switched telephone network must include E911 emergency calling
capabilities to their customers as a mandatory feature. The Federal
Communications Commission order, released yesterday, says that within
120 days:
** VoIP providers must deliver all 9-1-1 calls, along with
the customer's phone number and location, to the
customer's local emergency operator.
** Incumbent phone companies must provide access to their
E911 networks to any requesting telecommunications
carrier.

that selecting contracting, and training an appropriate call centre
will take longer than the time allowed.

By converting punched cards to 5-level paper tape you could send the
data over ordinary telegraph circuits and equipment, including the
Bell System TWX service. These circuits might be just wires, or
telegraph carrier channels, or they might include regenerative
repeaters for the 5-unit code. There were also private systems for
transmitting 5-level code within a company or organization - these
were supplied by Bell or by Western Union.
The Bell System didn't allow any "foreign" (meaning customer-provided
equipment) attached to the switched network. They vigorously defended
this position until it was overturned by the Carterfone case. If you
wanted to use customer-provided equipment you had to lease a private
line. You could lease a telegraph-grade line or a voice grade line
which cost a lot more. So the IBM card-to-card transceiver came in a
DC model that would work slowly over a telegraph line, and in an AC
model that would work faster over a voice grade line. And since it
did not need the entire bandwidth of a voice-grade line IBM designed
the modem with four different frequency bands so that up to four
systems could operate simultaneously over a voice-grade line.
The earliest modems were not really called that but were the carrier
systems installed in telephone and telegraph company offices to allow
multiple telegraph transmissions over a single voice-grade circuit.
The cusotmer usually didn't know or care whether his leased line was
wire from end to end or was transmitted over a telegraph carrier
channel.
Modems, in the form of carrier channel terminals packaged to be self-
contained, were sometimes used in manual TWX service to connect the
teletypewriter on the customer's premises to the TWX central office.
In the late 1950s the Bell System deployed a message switching system
for Delta Airlines. This used the voice telephone switched network to
connect stations to each other. A cabinet of equipment about four
feet high contained a model and an auto-dialer which went between the
telephone line and the very complicated Teletype set used to transmit
messages and dial numbers automatically. About the same time Bell
provided a voice-grade private line and high speed (1200 baud) modems,
called "digital subsets", to the FAA for transmitting weather data
around the U.S. on a private leased voice grade line. Also at that
time you could buy third-party modems operating to 2400 baud or so to
use on private lines.
Then in the early 1960s the Bell System opened things up by leasing
modems that allowed the customer to connect business machines to the
modem and transmit data over the switched network. The EIA RS-232
standard interface soon followed. In the same time frame they
converted TWX to a dial service, operating mostly over the voice
switched network. Some other services were proposed, including a Wide
Area Data Service, but these were shot down by the FCC. --

<snip>
See http://nordicgroup.us/prepaid which compares 17 prepaid plans for
the United States. It's a great site, as it compares all aspects of
each plan, including coverage, minimums, roaming, per-minute charges,
daily access fees, per call surcharges, etc.. I'd say that even if it
wasn't my site!
The short answer is this:
For the U.S., get a TDMA service from http://gobeyondwireless.com .
They'll sell you a TDMA/AMPS phone, or you can pick up a used phone
very cheaply (look at http://craigslist.org for the first city you'll
be in in the U.S.). The used phone must have previously been active
on AT&T's TDMA network (not Cingular's). There is no charge to
activate your own phone, and you can buy time on-line. Don't worry
about which area code you get. Minutes do not expire.
The other good option in the U.S. is CallPlus TDMA
(http://www.callpluswireless.com/). While they have a higher per-minute
rate, and a higher minimum, they do include international long distance to
many countries at no extra charge (see
http://www.locus.net/html/popup_50countries.html. Same deal regarding
handsets, they'll sell you one, or you can use an AT&T TDMA handset.
What about GSM in the U.S.?
---------------------
GSM service in the U.S. is not great, with large areas still having no
coverage. SIM cards are quite expensive, as are prepaid minutes. If
you go the GSM route, avoid T-Mobile, and go with Cingular, and be
certain to get a phone that supports 800 Mhz and 1900 Mhz GSM (800 Mhz
is sometimes called 850 Mhz).
What about CDMA in the U.S.?
----------------------
Coverage is excellent, but prepaid CDMA is more expensive than prepaid TDMA.
Europe
-------
For Europe, the best deal is to obtain an unlocked dual band (900/1800
Mhz) GSM phone, and then use Riiing. You didn't say where you are
located, you can see the Riiing product at
http://www.planet3000.com/SIM_INTL_riiing_DTL.shtml.
GSM Phone for Europe and Riiing
------------------
Triband GSM phones (900/1800 & 1900) are very cheap now, because they
are not well-suited for the U.S. anymore because most GSM is at 800
Mhz. See http://store.yahoo.com/sentimentalgifts/mott2gsm90mh.html for
a good deal on a tri-band GSM phone. For U.S. GSM use you want a dual
band 800/1900 Mhz handset, or a quad-band (800/1900 & 900/1800). The
quad-band GSM phones are still pretty expensive.

Our Usenet feed went away for several months and I have only recently

cause the ionosphere to become more reflective of higher-frequency
radio waves at various times.

Solar cycles called Cycle19 in the late fifties, but I do remember all
the rest from the late sixties to the one that is just now winding
down.
In November of 1970, I heard BBC1 TV audio in the 41.5 MHZ range for
the first time here in the very center of the contiguous 48 United
States.
When Solar activity began to peak in the late seventies again, the BBC
was back during our Fall and Winter months. We would start to hear
some of the transmitters begin to fade in around 08:00 or so on a good
day. If it was a really good day, the 45-MHZ video buzz would be
there, also. The 30-50 MHZ band is used for two-way radios and paging
services in North America so the video was _NOT_ amusing to users of
that spectrum such as state police agencies. The Oklahoma Highway
Patrol which polices primarily traffic regulations on those parts of
roads that are not part of some municipality suffered withering
jamming for hours at a time by video sidebands off the 45-MHZ center
carrier as the Highway Patrol used several frequencies between 44.7
and 45.22 MHZ.
The signals usually came and went, sometimes reaching what one might
call local quality until about 1 or 2 in the afternoon. By that time,
it would be well after dark in England as we are UTC - 6 in the
Central Standard time zone.
Due to the fact that F2 Layer propagation above 30 MHZ is almost
exclusively a daytime-only phenomenon, the reception of BBC1 audio was
always a mid-morning to early afternoon experience for us. One could
hear programs aimed at children coming home from school and the
evening news and weather among other BBC programs.
A few other notes are in order. The BBC wasn't the only television
service audible during those exciting times. The French also had a
Band-I service whose audio was at 41.250 MHZ plus or minus offsets.
More often than not, both the British and French television audio were
simultaneously receivable so it is good that they weren't on the same
exact frequencies.
If you consider the distance between Oklahoma in the middle of the
continental US and the UK or France, one would expect the propagation
to be almost identical, but the path tended to favor the French
system. Either their transmitters were run at a higher power level or
the angle of propagation for the signals was more favorable to France
than to England. Also, various transmitters in the UK would be
booming in loud and clear while others were barely audible.
Both the French and British television systems made extensive use of
offsets to minimize video interference to television sets near enough
to receive signals from two transmitters at the same time such as what
would happen if someone lived in the countryside between two towns
whose Band-I transmitters were on the same channel. On the BBC1
system, the offsets appeared to be about twelve KHZ or so which meant
that with a selective AM receiver, one could tune in the London area
or the Northern Ireland transmitter.
One slightly amusing thing I remember was that one of the BBC
transmitters must have had a crystal oven that wasn't too accurate.
Its signal would whistle or heterodyne against another BBC transmitter
in another part of the country, but the pitch of the note would begin
to rise or fall through zero beat within 20 or 30 seconds. A few
minutes later, it would shift back the other direction. I am guessing
this coincided with the cycling of the thermostat and the heating and
cooling of the crystal.
The audio, by the way, for both the British and French systems was AM
or amplitude modulated. The video for at least the British system was
405 lines at 50 fields per second. A few hobiests in the US actually
cobbled together modified monochrome television sets and tuners and
were able to get scratchy images. I was told that without modification
to the video circuits, the images were reverse polarity because the
405-line system used the opposite signal levels for black and white
than do modern PAL or NTSC systems.
If one reads the book, The History of RADAR, there is an interesting
footnote to the British Band-I system. Since the UK figured that war
with Germany was imminent in the late 30's, the decision was made to
pump money in to the fledgling television equipment manufacturing
industry in England because the manufacture of TV picture tubes and
VHF transmitting and receiving equipment fit perfectly in to the still
top-secret efforts to develop useful radar systems for defense.

Exactly. But then, you never had to tell the phone company where you
were with circuit switched.
That being said, when I switched to Vonage I knew about the 911 issues
ahead of time. I put in my address, researched their work with RI
E-911 and even tested to be sure everything was functional.
So now if for example, my service goes out like it did between 5:30PM
and 6:00PM yesterday I have a legitimate gripe with Vonage. But if it
was my own stupidity there is no one to blame but myself.
I smell a major rat in this whole scenario. The incumbent carriers are
scared to death of VoIP because it proves that they've been raking us
over the coals for many years. In fact it is worse now than it once
was. My first phone line cost a grand total of $12.00 a month and I
was renting the phone. Now a basic line with message unit service
costs $30.00 after all the taxes and fees.

Southwestern Bell yesterday; this one offers a _full year_ of the e

Could someone put a brief explanation of :
OPT- IN
OPT -Out
Thanks,
[TELECOM Digest Editor's Note: 'OPT' means 'optional', and it is the
opposite of 'default', or the way 'things would normally happen'.
In the context of this thread, Vonage has not been normally providing
a working 911 service. To obtain 911 you have to make an effort to
get it, by notifying the carrier. That would be 'OPT-IN' or ask to
be included in whatever the program is.
OPT-OUT (or option-out) is when the 'default' (or the way things normally
happen) is to include you, but you do not want the default to happen,
you want to option yourself out of the program or event being offered.
Again, in the context of this thread, Vonage intends within ninety
days -- probably due to recent government fiat -- to change their
default (the way things normally happen) to be valid 911 service for
everyone. If you do not want what will be the new norm, of emergency
phone service, you will have to take action to be excluded (Opt out)
rather than before when you had to 'Opt in' to use the emergency
program. PAT]

Autovon used "standard" Touch-tone phones. Ones with *all* the buttons.
including the 4th column of 4.
Autovon actually made use of those 4th-column buttons, for things like
indicating the 'priority' of the call. If all circuits were busy and
you had "priority' traffic, you could push the magic button for that,
as part of dialing the number, and some (random) "non-priority" call
would get abruptly terminated, to free up the required circuit, so
that your call could go through.
There were other 'specialty' capabilities as well, specific to a
"command and control" operation.
The 'enhanced' features (including 'priority') were not necessarily
available on -every- Autovon phone -- it took a certain 'class of
service' as it were, before one could use them. And, of course, there
were very specific 'policy' rules about _when_ one could use them.
[TELECOM Digest Editor's Note: As Robert knows, those four additional
touch tone keys were known as A,B,C, and D. I forget the exact
meaning of each, but my question is, did anyone with 'regular'
service but with an Autovon phone ever try pressing those keys in
a regular call? I did a couple times, and the immediate result was
a 'fast busy' signal; the call would not complete. PAT]

Um ...
This has never been a secret with Sprint; in fact, if you look in the
user manual for any recent phone it will *say* there are charges. It's
in the manual for my Samsung VGA-1000...
The only per-minute charges are for the old 14.4Kbps slow wireless web
access. PCS Vision is billed either flat-rate or per kilobyte
transferred depending on which Vision package you have.

I believe the issue is that even once you activate it, you wouldn't
get connected to real E911 services. The LECs didn't provide them
with the proper access to the E911 infrastructure, so Vonage was
forwarding 911 to administrative offices rather than 911 operators.

Well, my number was transferred yesterday (the same day I called MCI

The above quote, attributed to Mr. Jeff Pulver, is disingenuous at
best and just plain false at worst. As part of their deliberation
process, the FCC spoke directly with people already affected by the
lack of reliable 911 functionality on their VoIP service. In fact,
lives have already been lost because of this shortcoming. Saving those
lives in the future would be substantially more than just "a quick
political sound bite."
If I invented a new kind of engine that promised 100 miles per gallon,
most people would agree that would be a good thing. If that engine was
unable to meet current federal emission standards, however, I would
not be permitted to sell it. I would be able to test it and develop it
but I would not be able to sell it to the general public until it did
meet those standards. I could complain that the government was
"stifling my ability to move forward with this radically new engine, a
machine that would change our lives for the better" but I would still
be required to meet current emission standards before going to
market. My complaints that the Model A Ford had no such restrictions
placed on it would not carry much weight.
We have a similar situation with VoIP. apparently, lives have already
been lost or, at least, imperiled. Regulations exist for a reason. In
this case, the reason is the preservation of life and property. We
must decide if that is at least as important as the preservation of

I know for a fact that's not true with Sprint at least. If you buy

Sprint will not require a contract for postpaid service if you pay $10
per month over and above the normal plan fees. You can even switch
from being in contract to doing the $10 per month (but you will have
to pay the $150 early term fee for that privilege). Of course, they
don't charge you extra for month-to-month if you've fulfilled your
contractual obligation.
Back when my wife got her Sprint phone in late 2000, their in-store
local coverage map didn't indicate that our neighborhood was covered
-- which is odd, because they have a tower a mile or so from our house
-- so we went month-to-month for a couple months until we were
satisfied that coverage was what we needed, after which we signed a
contract and eliminated the $10 fee.
