Can't say without knowing the particulars on the T1 at work. There's lots of kinds of T1s out there:
some people refer to any connection of 1536k as a T1 when it might be DSL/cable.
there are fractional T1s where, yes, there is a full T1 local loop, but the port size is smaller, such as 512k. These connections can either burst up to the full T1 or can be cut off at that exact 512k and not allowed to go higher. Depends on what was bought/delivered.
There is also an integrated T1, where voice lines and internet data reside on the same link. Most of the time, it is not dynamic, so you will have a set amount for data, such as half and half-- 12 voice lines and 768k Internet, for example. In a dynamic allocation situation, the Internet bandwidth will fluctuate depending on how many voice calls are going on at the same time.
All T1s are not created equal. Krazy Klown Telecom might sell a $250 T1 that will in no way match the performance and reliability of a UUnet T1, for example.
