An amusing anecdote, which may possibly be untrue today: I wanted to order 48 lines of MegaCom bulk 800 service (2 T1 lines) from AT&T. I was told that the circuits were entirely digital to the toll office, where they were broken down into 48 two-wire analog circuits, then sent downstairs (in the same building) to PacTel, where they were re-multiplexed (on a channel bank *I* had to buy) into digital T1 for shipment to the customer site. I couldn't even get four-wire circuits between the channel banks. Marc Kaufman (kaufman@Neon.stanford.edu)
