That was my arguement too Sam. I claimed that this was "more DSL than T-1," but that is allegedly what AT&T is installing around here. The CLEC claims that they have no power over what type of circuit the ILEC supplies as long as the data transfer meets spec. We do have a straight line back to the cloud, and right now we're getting our synchronous speeds of 1.5, (minus reasonable overhead,) but my research on these circuits leads me to believe that when the office is full, and users are both up and downloading at the same time we're going to see problems.

To answer your second post Sam, it's an integrated T-1. It comes into a smart jack outside, then in the phone room it hands off to an IAD which breaks out the voice into analog ports and hands the data off to the firewall.

It appears to me to be more of an HDSL, but I'm finding a lot of talk on the net where people are facing the same problem with them refusing the extra pair.
