A manual exchange could have 10,500 numbers. Also, if the phone number had a party line suffix, eg. HOllis 5-9242J, the J was dialed, too. Literature on the panel exchange in NYC confirms the registers could hold and pass 8 digits. I don't know if that applied in other big cities. When calling from a dial exchange to a manual exchange, the desired number appeared on a display panel in front of the manual operator. She merely plugged into that number. Manual service continued in NYC until the early 1950s. A late 1940s telephone strike steeply reduced service to manual exchanges--the public was asked to make emergency calls only. In the early 1950s, NYC subscribers could dial 'toll' calls in Long Island instead of going through the operator. Instead of being billed 10c or 15c for such calls on an itemized basis, the message unit meter was incremented accordingly for distance and time (the meters already existed to do that for local calls). Some subscribers complained about the loss of itemized billing, but it undoubtedly saved the phone company a lot of clerical processing.

Subject: Re: AT&T advert from 1970s re: World Trace Center Message-ID: <email@example.com> >There was a Verizon CO down the street that had its windows and part >of a wall blown out. Yes, this is the source of the myth that the Internet is more resilient than the phone system. By sheer coincidence, there is a major NYT (now VZ) central office in the VZ headquarters building at 140 West St, across the street from the WTC, which was badly damaged when the WTC buildings collapsed, also due to water in underground vaults, seriously disrupting both voice and data circuits. The major Internet hub was (and is) 60 Hudson St, the old WU building, which was far enough away to be undamaged, so Internet service was OK to the extent it didn't depend on circuits going through 140 West St. If the buildings happened to be swapped, the meme would be that the Internet collapses in a disaster and the phone network is rock solid.

Ironic that the hub of message record communications is the Western Union building, which used to handle message record telegraph traffic. As discussed before, the old Western Union company had high hopes to be a big player in data communications, since after all, that was their primary business. I still wonder, given the benefit of hindsight, if anything could've been done differently to save the company and let it be part of the data comm revolution. (There is some suggestion FCC unfairly favored the Bell System over Western Union in some regulatory decisions). The former long time AT&T HQ was at 195 Broadway, not far away. The original AT&T is gone, too, having been bought out by one of the Baby Bells. Do they still have a presence in Bernardsville, NJ, where their network communications center used to be? Is the statue of Golden Boy still out there?

Part of the transition, at least in the NYC area, was the inclusion of arbitrary two-letter office codes which had no name. Mid 1960s, IIRC. The one I remember best was LT1-xxxx. Probably the best known number out of that office was the main number for WABC-TV, LT1-7777, pronounced 'Ell-Tee-one ...'. I also vaguely remember an 'XX' office code, letter X, as in dial 9, not a notation for an arbitrary digit.

Well, as other threads have indicated that doesn't always work either since after a major event everyone goes to use the network and because of the load on the network your call fails. The more likely reason that people were getting more cellphones in 2001 is that they were becoming cheaper and it became "normal" to have a cellphone since you could have a phone for as little as a few dollars a month.

It should be noted that implementations of new technology back then often had three levels: --Initial experiment. This would be making a long distance call over a long circuit, the first transmission of television, the Morris IL ESS, making a working transistor, etc. It is a long way from successful experiment to actual commercial installation. --Commercial installation: a regular installation for paying customers, such as the Susc. NJ ESS, public TV broadcasting, use of transistors in production productions. --Widespread usage: It takes time after the first commercial installation for a new product to become widespread. For instance, the Bell System continued using some open-wire transmission into the 1970s before more modern methods replaced it. While commercial TV came out in 1940, then more so in 1948, it took time before all cities had it. In the case of early long distance transmission, the Bell System may have had a successful test of a long distance conversation early on, but it took time before all the elements necessary to make that happen were developed to an adequate level to be affordable, reliable, etc to use in real service. For instance, many improvements to vacuum tubes were required to make repeaters possible--a higher vacuum, physical arrangement of the components, materials used in the components. For example, considerable experimentation was required to develop the optimum metal alloy of the grid and filament, as well as techniques to manufacture those components in quanity. When the transistor was developed, it took about ten years to understand its operating principles, figure out the optimum materials and 'doping', and development high-volume reliable production manufacturing. It took a few more years to get the cost down below tubes (there were plenty of consumer electronic products of the early 1960s made of tubes, not transistors). The first volume of the Bell Labs history (op cit) goes into detail about all of these issues.

Subject: Whoa - Apple Wins a 3D Display & Imaging System Patent Stunner Message-ID: <email@example.com> Whoa - Apple Wins a 3D Display & Imaging System Patent Stunner Patently Apple September 13, 2011 The US Patent and Trademark Office officially published a series of 13 newly granted patents for Apple Inc. today and one was a real stunner. Today's report focuses on this advanced 3D display and imaging system that packs one hell of a wallop. Apple's patent covers a wild 3D system that could generate an invisible space in front of the user that could allow them to work with holographic images or project their hands onto a screen in front of them to manipulate switches or move pieces of virtual paper or parts of a presentation. One could only image how this could be applied to 3D gaming, business or medical applications in the future. This is Apple's second major revelation about such an advanced 3D system and many supporting patent applications would suggest that the system is progressing quite well in Apple's research labs. The good news, is that future iOS devices will be one of the drivers behind this new beast. This is definitely one of Apple's coolest ideas to date. ... http://www.patentlyapple.com/patently-apple/2011/09/whoa-apple-wins-a-3d-display-imaging-system-patent-stunner.html

Surely they were destroyed, too. From a 1999 edition of the LERG, NYCMNYST was the CLLI code for 2 World Trade Center. It had three Verizon entities listed there: NYCMST00W - an old data switch NYCMSTCG0 - A 1AESS (analog) switch NYCMSTDS0 - A DMS-100 I'm guessing that the 1A was retired before 2001, quite possibly before 1999 (the LERG sometimes has old entries left behind). NYCMNYWS was the West St. CO, next to WTC, which was severely damaged by falling debris. It had a whole heap of switches in it. Not to mention NYCMNYJV, 1 World Financial Center, also next door to WTC, And possibly others whose street addresses were not "World Trade Center" but were impacted. -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701
