Re: Information capacity of a T1?

[Mel Beckman]

A T1 is full-duplex, and can send and receive 1.544 Mbps in both directions simultaneously. I wrote a book on the subject (LAN to WAN Interconnection: A Handbook for the Perplexed, McGraw Hill; ASIN: 0070196141; (August 1995)). A T1 consists of a transmit pair and a receive pair, which are completely independent (other than sharing the same clock). I only have the Chinese edition of my book left, but I'll cheerfully send you a copy <grin>

Folks:

There's a controversy about the amount of traffic that a T1 circuit can carry.
Obviously, it can send, or receive, 1.544 Mbps per second.

But can it send *and* receive 1.5 Mbps simultaneously? Or does the total data
carried (send plus receive) max out at 1.5 Mbps?

I've heard people who ought to know give both answers. So I'll open the question
to the world's experts and ask this list.

There's a T-shirt for the best answer. Extra credit will be given for a tutorial
(or links to tutorial information) about how this stuff works. Thanks!
