I have a Strange problem with a point to point T1.
I have a 2610XM (Site A) With 3 WIC-1DSU-T1-V2 Cards in it, Two of thos T1s are point to point T1s to a 1721 on the other end. I am running PPP with MLPP across those T1s.
The problem is that one of the circuits changes state every 2 hours and 16 minutes.
If the circuit is up, it goes down. If it is down it comes back up. This happens EVERY 2:16
While the T1 is down, the Site A interface Shows Down/Down and a remote alarm. The Site B side Shows UP/DOWN.
