Qwest T1

Hmmm. I disagree with some of this, but it's not important. Basically, =
you need to identify the actual demarcation point. It's not necessarily =
the NIU/Smartjack. It could be three floors up terminated on a surface =
mount RJ48 type interface. Looping up/back the NIU only tests the cable =
pairs to the NIU, no further.

The other point well made here is to get your vendor involved.

Cheers,
