Because we are selling them a 128K connection, and the only kind of
line we can get is a full T1, they don't have Fractional T1s in this neck
of the woods. Frame relay is only if you want to tie into the BellSouth
network.

> I think I would need to know more about the circuit design. At the T-1 level, all timing is passed through, unless, they run this circuit through a DS0 DACS to limit the speed to 128k, then you would have to take timing off of the loop on both ends.

We are treated as mushrooms, we are kept in the closet and fed
bullshit. If you know what I mean.

Need more info.
All the info we got was that they had some kind of problem with a
repeater on the T1.
