This is very debated topic.
Quick answer is: a T1 is full duplex: 1.544 in both directions. Here is a sample graph from one of our links showing both inbound and outboud sometimes peaking at 1.544 (especially the rightmost wednesday)

Bell Labs Tech Doc 62411 is the official spec... You can get a copy here:

Or you can do a search on this publication and see what comes up. You may get a lot of crap about CSU/DSU's which are covered heavily in the ATT publication.
For links, I like this document:

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!
