The clerk was a moron. They sell you a SIM (or a prepaid phone with a SIM), then activate it and assign you a telephone number. That's how prepaid service works in the US. This is exactly what I did in an AT&T store in NYC last month. He said he could only assign me a number in the NYC area -- if I wanted one upstate where I live I'd have had to call 611 later and have them change my number. SIMs aren't tied to phone numbers. That relationship is made at the switch. That's why you can move an existing number to a new phone, and change the number on an existing phone. R's, John

Subject: Comcast Tests Tech Overhaul Message-ID: <4DDE7C88.firstname.lastname@example.org> By jessica E. Vascellaro Comcast Corp., facing a growing threat from online video services, is fighting fire with fire. The country's largest cable-service provider soon will start testing a new way to deliver its television channels, co-opting the same technology standard that upstart Internet rivals have used to challenge traditional pay-TV business models. Using the MIT campus as its proving ground, Comcast in coming months will try delivering TV channels using the same standard used to deliver data over the Internet, known as the Internet protocol, or IP. Like other cable providers, Comcast currently delivers channels over less versatile digital television technology that sends the video in streams to set-top boxes and isn't compatible with the Internet. http://tinyurl.com/3o6erko

Message-ID: <email@example.com> In April 1982 the BSTJ reported on a new remote switching system, the No. 10A, that was intended to economically replace small step-by-step community dial offices and provide ESS features to subscribers who otherwise couldn't get them. Table of Contents of that issue: (very detailed description of the system) http://www.alcatel-lucent.com/bstj/vol61-1982/bstj-vol61-issue04.html The No. 10A is a slave system to a larger ESS. IIRC, many small switching offices were indeed replace by this or other arranagements. In a sense, this switch is a fancy line concentrator. Now, nearly 30 years later, would anyone know of the actual service experience of the 10A or similar functional units? It seems like a good idea, and given the huge drop in the cost of electronics since that time, probably more such systems have been deployed. Of course the flip side is that many tiny communities with a CDO have grown as a result of population growth and suburbanization and would need more capacity.

Subject: Early Voice Mail ("voice storage") systems Message-ID: <firstname.lastname@example.org> The May 1982 issue of BSTJ has a seires of articles on voice storage. This technology led to voice mail services. As usual, Bell Labs extensively researched the architecture, physical design, software, office engineering, maintenance, and reliability, with articles describing in detail the findings. The preface says the FCC ordered Bell to cease work on this system as it violated regulatory policy--it was considered a premium add-on in violation of "Computer II". So even though in 1982 Bell's competitors were providing both transmission services and customer equipment, Bell was forbidden to offer its own premium services. How much of this research carried forward to voice mail systems I don't know. But I can't but suspect that subsequent private developers benefited from Bell's original research and trials. table of contents may be found at: http://www.alcatel-lucent.com/bstj/vol61-1982/bstj-vol61-issue05.html

Since there are security issues with SIMs/handsets these days the customer identification credentials are probably the issue, not any technical issues. If is probably the difference in the internal bureaucracy between the two organisations. -- Regards, David. David Clayton Melbourne, Victoria, Australia.
