Just to add to what other folks here have said, remember that your point to
point link is not a physical wire from one end to the other.
Most likely the middle is ATM with a CBR.
Main_office-----C/O--------carrier_network--------C/O-------Branch_office
>From the phenomenon you describe, I would say that there is a problem on one
of the local loops. Either your CSU is not configured properly, the CSU in
the CO is not configured properly, or something else is in the loop, so to
speak. The other side is ok, because as far as it is concerned, it is doing
what it is supposed to with the C/O equipment to which it is attached.

Subject: OT: Point to Point Serial link
I have a production network where one side of a point to point serial
link is showing up/down and the other side is showing up/up. I thought
that if one side went down they would both go down. I know on frame
relay one can be up/up and the other down, but I thought on a point to
point this would not be the case. Am I missing something basic here? I
am running the T1s into 2610 routers with built in WIC-T1-CSUs.
Thanks.
Eric
