Well, duh!  You do have to test each part if you want to eliminate things, 
but where you start is up to you.  If you've already replaced your end of 
the hardware (several times, as I think he said), then odds are pretty 
good it's not your hardware.

Bellsouth, Sprint, Verizon, a number of lesser known CLECs.  Once you're 
confident enough that the problem is definitely the LECs part of the 
circuit, just tell them you want a T1 tester dispatched and if they find 
the problem is in your stuff, you'll pay.  Unless you've skipped testing 
some part of the equation, you're not going to be out any $.

I missed that at the very bottom of the original post but saw that he was 
simply losing packets at the top of the message.  I see now, he said the 
LEC is seeing receive errors on their end.
