And that includes customer-owned portable wall-mounted phones. Such phones were attached to a telco-provided backplate fitted with a modular jack and two mounting studs to provide physical support for the phone. The backplate was permanently installed on the premises. The whole interface was identified by USOCs RJ11W (single line), RJ14W (two lines) or RJ18W (single line with make-busy feature). In order for this arrangement to work, it was necessary to design a plug-and-jack interface that would make the proper electrical connection when the phone was installed, but would disconnect without damage when the phone was removed. Wall-mounted modular jacks also had to accept wired phones so the jack had to be equipped to accept the "little plastic locking tab" that AES mentioned. And, of course, the whole concept--plug, jack, and cord--had to be designed so that plugs could be attached by non-telco personnel (including the general public) with inexpensive tools. It's easy to criticize the whole modular concept, but if you consider the requirements I've noted above, you begin to understand why the industry and the FCC chose it. Modular interfaces were defined in Part 68 of the 1997 (and earlier) editions of the FCC Rules and Regulations. A PDF of the 1997 edition is posted at http://tinyurl.com/OldPart68. USOC configurations are defined in Section 68.502, beginning on page 394 (PDF page 134). Neal McLain

However, I wasn't criticizing the modular concept per se. I was criticizing the design of the "lever" on the modular connector, which in many (most?) cases was angled outward pointing back along the cord -- a perfect "fishhook" to catch on anything it came close to. Surely some other "snap-in" design or level design would have possible.

Here it's an outfit sending AC 918 and CID "TCIM", whose emissaries say, "Hi, this is [FirstName] calling from Bank of America to ... ." When I interrupt to say, "That's funny, you need to tell your supervisor that Caller ID reports you as TCIM," they answer, "That's right, and we're calling on behalf of Bank of America to ... ." When I suggest that, as I'm not interested in whatever they're offering, they put me on their own internal Do-Not-Call list, they answer, "The Do Not Call Registry doesn't apply here because you're already a Bank of America customer." My response: "That would mean I have a customer relationship with Bank of America -- but not with you, who are merely a third party marketing partner. And anyway, what I'm asking is that you add this number to your own, in-house, Do-Not-Call list." And that they nominally agree to do. We'll see :-) . Cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP ***** Moderator's Note ***** The easiest way to avoid the problem is to avoid being on their list in the first place. I always lie when banks or other businesses ask for my phone number: I think that since they're never going to call me for anything important (_that_ kind of service is gone forever), they deserve to have their time wasted.

Apparently they weren't a very popular >option; I KNOW they were uncommon. <grin> When we put it in, it was the only such unit in the entire state, and, I believe, all of NW Bell territory. In either commercial or residential service. The second installation in the state was nearly 10 years later -- a budget business-class hotel put in a bunch of them as the 'house phone' in all the public areas. Made sense for that use -- didn't have to have any furniture near it, just a piece of the wall; no cord to get tangled, etc. Not sure what they used in the rooms themselves, > I think far more people went for Trimline or Princess sets. I'm sure lots more people went for trimline/princess sets. The panel phone was one of a handful of 'specialty' telephone sets that Bell offered -- ones where you shelled out a bunch of money to 'buy' the phone (actually just the housing), and then paid a recurring monthly for 'renting' the actual phone mechanism innards. What, a decade later, was marketed as the (greatly expanded) 'design-line'. If I'm remembering right (some 45 years later) the 'purchase' price for that phone was something like $120. Including the installation. Which was a significant chunk of money in 1964 dollars.

No. Originating switch "doesn't know" if/when the call will leave the network of the originating C.O. Multiple reasons.
  1. IF it does leave that originating network, money changes hands with the destination network. For cost-accounting, and 'audit' thereof, purposes both telcos need a unique identifier of both endpoints of the call.
  2. 'Caller' info is required to be available at the destination switch, to meet various law-enforcement needs, per statute.

Subject: Re: What is a "female-specific mobile handset"? Message-ID: <4CB4946E.8070704@AmericanCLEC.com> I hope just coloring a phone pink is not the answer, I am a woman who hates the color pink. I would think making phones smaller so that they fit better in a woman's hand would be nice, for me some Blackberrys feel very cumbersome because they are so wide. The other issue I have is finding headsets that fit my tiny little ears properly (the Jabra 125 fits well though). -April Coffman
