KX-T: Strange Disconnects

The key is to be able to duplicate the problem at will. Once you're able
to duplicate it, you'll be able to nail it down.

First, swap lines 3 and 4, and see if the problem moves. If the problem
stays on line 4, then it's the card.

If the problem moves to line 3, swap 3 and 4 back, then remove line 4
from the surge protector (unless the surge protector is grounded
directly, it's not doing much good anyway).

If that doesn't resolve it, DC from the KSU and answer the line directly
with a buttset at the KSU. 

If the problem is still there, do the same thing at the demarc.

If the problem is still there, then send it to the LEC. If the problem
goes away, change to a new feed pair.

Subject: RE: KX-T: Strange Disconnects

Hey all.  Been on hiatus from this topic for a few weeks, but the
behavior is still occurring.  Recap:

Been getting disconnects on our line 4, which is automatically forwarded
to our TVS-50 and is used as an incoming AA line.  Users are reporting
that the disconnects occur between 1 and 4 minutes into the call.

I have not been able to track down any other similarities, other than
the calls all appear to be on the same line.

Does anyone have any ideas as to what to do in order to track it down?
Am I looking at possibly a hardware (phoneline) failure?

Also, the incoming phone lines go through a power-strip/surge supressor
which is also designed to suppress CO surges into the system (in other
words, all CO lines are coming into this strip for supression).  This
power strip is hung directly off of a UPS.
