Sounds amazingly like ISDN (except for the limit of 5 data calls, since the ISDN D channel has no such limit, as far as I know.) They also seem to imply that you don't need more pairs. ISDN needs 2 pairs instead of 1. I wonder if Victoria really only needs 1 pair? >No decisions have been made on how much the new service will cost or how it >will be marketed. John Lucas, a Pacific Bell spokesman, said that if a new >digital standard emerges, Victoria can be modified to be compatible. Sounds like Pacific Bell has never heard of ISDN. For Pete's sake, ISDN is an international standard! It's been implemented on 5ESS, goes on trial in Illinois this year, and our soon-to-be-upgraded-to-5ESS is expected to have ISDN installed and working in 1987.

I believe ISDN has several different interfaces and that one of them uses a single 2-wire interface. The exact data format and whether and what kind of echo cancellation will be used are still under discussion. -- I love to go skiing on a Super Bowl Sunday.
