Thanks for the answers. So in a perfect world, the telco would terminate on an 829 at the telco entry point for the facilty then extend the circuit to the modular jack w/shorting bars. Right? I've always refered to the 829's as Smart Jacks...incorrectly I guess.

Next Question:

When the telco terminates a T-1 in a facility, it has to have a certain amount of signal strenght, right? And is this signal strength measured in gain? And if the signal strength is a bit on the low side, can they increase the gain or adjust the LBO for that T-1? If so, where would they do the adjustment...at the 829?

Again...thanks in advance for your help!!
