Let me attempt to clean this up a bit - I used to work for one of the RBOCs and this has always been a source of confusion - even for people who worked there!

It does not matter if a carrier system is handling voice or data, or is being fractionalized at each end to carry a combination of the two, a T1 and a DS1 are the same thing - a physical transport facility carrying digital information at a 1.544 Mb/sec rate (when using framing - a T1 transports at 1.536 Mb/sec if no framing is used).

For a really good workup of the history of the T1, go here: http://www.dcbnet.com/notes/9611t1.html
