I have had the same thing. Once I was having a timing problem and was
troubleshooting with the telco and finally convinced them to swap out some
equipment at the CO(a mux I believe). The problem cleared up. About 3
months later the circuit bounced and the same problem was back. They had
tried to put that same equipment back in. I called them within 15 min of
the problem starting and told them they must have put there broken equipment
back in. The circuit bounced about 15 min later and was back up.

Hmm.... and it's not the fault of USWorst?
A couple of things come to mind -
You may in fact have a bad CSU; can you replace it with another unit
and see what happens? How far are you from your demarc (where the line
enters the building)? And how is your line build-out set? Are you running
hot?
BTW - what haven't they replaced? I have had arguments in the past
with Telcos and providers who swear that their equipment is not at fault.
Once they finally replace their equipment (usually their line interface),
everything works fine.
HTH - that's my $.02

Subject: Slightly OT: Telco Line Problems
We are having some odd line problems at one of our branches that none of us
have been able to figure out so I thought I'd throw this one out to the
group.
>From time to time, sometimes many weeks in between events, our csu/dsu
begins to report OOF and AIS (T1 yellow alarm) errors, but the line will
stay up for a while. Then, at some point, we'll get a T1 red alarm and the
circuit will die. We call USWest who then tests the line. According to
them, they've replaced just about everything between the CO and our
location, and the line tests clean. Friday it was bouncing every 30-60
seconds so we had them test it again. Since the test, it has been error
free but they claim not to have discovered any problems.
This is the endless cycle so far: the line dies, they test, they report no
problems, line mysteriously works fine after test for a several weeks, the
line has problems, the line dies, they test...etc.
My only remaining guesses are these two: bad csu/dsu that isn't bad all the
time, or intermittent problems at the location (we share it with a very
large supermarket.)
Any thoughts?
TIA,
