Subject: Chubby fingers vs "Smartphones" Message-ID: <firstname.lastname@example.org> As someone who has to continually set up these things to interface with Exchange systems, I can totally relate to this cartoon even if my fingers aren't too chubby! (I really hate interfaces designed for those under 30 years old...): http://www.dilbert.com/fast/2011-11-27/ I don't think I've set one up yet without swearing over mistyped server DNS entries or user credentials.... -- Regards, David. David Clayton Melbourne, Victoria, Australia Knowledge is a measure of how many answers you have, intelligence is a measure of how many questions you have. ***** Moderator's Note ***** The interfaces aren't designed; they're dictated. The Salesdroids demand something that looks familiar and easy-to-use, because that's what moves the product off the shelves. The problems that come after the sale are externalities to the Salesdroids. A competently engineered design would have a stenographer's keyboard, a few context-sensitive function keys, and a screen that can be seen in daylight. Bill Horne Moderator

Message-ID: <email@example.com> On the commuter train on Saturday I noticed it was quieter than usual. Typically on a weekend many passengers, especially the younger ones, are yakking away on their cell phones making the train rather noisy. (That's why some railroads have introduced "quiet cars", though not on weekends). Anyway, I did notice a number of passengers 'thumbing away', that is, apparently sending and receiving text messages. I understand text message traffic has gone up, which the cell carriers love because texting uses less bandwidth capacity than a voice call does, but they charge more for it. One needs to pay extra to get unlimited texting. Otherwise, as many parents found out the hard way, texting is expensive. Has text message traffic overcame voice message traffic? Could someone expand on today's cell phone traffic mix? Thanks. [public replies, please]

There were tariffs for "speial assemblies" which provide how costs would be charged for items and services not listed in the approved tariffs. Each one was costed for its particular assembly, and there were many special assemblies written and installed by telephone companies everywhere. Customers, especially business customers, had useds for all kinds of things not enumerated in the tariffs. In the 1940s, I worked as a reporter and editor for the Daily Oklahoman / Oklahoma City Times in Oklahoma City. On the switcchboard multiple, besides the local dial trunks, there what we could now call s "rotary group" of toll trunks, assigned number L.D. 343, which gives an idea of the volume of toll traffic. There were also tie lines to and from other related businesses, as well, I believe to the Washington, D.C., bureau. There was also L.D. 419 which appeared on a regular black set on a desk behind the city editor, bypassing the switchboard. In my experience, the switchboard operators were more then pluggers. If someone asked for Mr. Smith, the PBX operator probably knew the number and would connect to it without further discussion. They also took incoming calls and messages, and were uncanny in guessing where someone was if they were away from their desks. > The studios probably were liberally equipped with extensions, > trunks, and, key systems in offices.0 My guess is that they may have > had more trunks and extensions than other large businesses.

Newspapers were also very big users of communications services, by the nature of the news business. Many of the buzzers and squawk boxes were part of the telco provided quipment and integrated with the key systems. > Studios may have extensively used "code call" which was a system of > coded flashing lights that signalled a particular person to call > in.

Telegraph channels were also provided by the telecos, presumably at competitive rates, in view of the number that were provided by the telcos. TWX was a switched service. A private line system connecting Teletypes was called just that, not TWX. The nation was blanketed by such systems of the United Press (for which I later worked), Associated Press and International News Service, with local, regional and national wires. All of them I was familiar with were telco-provided, except on Saturday afternoons and nights in the fall when W.U. had rights to various stadium and private circuits were ordered from them to the selected wire service bureau or to some newspaper that sent thir own sportswriters. Sometimes W.U. would provide Morse operators with their keys and sounders. It was always a pleasyure to get them because they were so skillewd and understood what they were doing and could break immediately and send a query if there was some question that needed to be raised. > Like many industrial sites of the time, they may have owned a > separate in-house telephone network for internal calls.

As I recall, all Montgomery Ward stores had their own isolated systems. On the other hand, later when I was working for the Bell System, I knew of one industiral installatiion on the Gulf Coast that chose to go with Bell even thought it was higher in cost because of the massive ability of the Bell System to restore service after a hurricane. > In those days one could ask the long distance operator to "get me > John Smith in Scranton" and the long distance operator would call > distant directory assistance to get the number, then place the call > person to person.

I remember the first time I had a call handled by interoffice dialing. I worked in the Dallas bureau of United Press and called for our correspondent or client in Corpus Christi, passed my call and expect the next thing I heard would be the Corpus Christi inward operator answering and the Dallas operator passing the number. But the next thing I heard was the C.C. number ringing. Wes Leatherock email@example.com firstname.lastname@example.org
