7206VXR/PA-T3+/Frame-Relay PVC Status Keeps Changing
We're seeing all PVC's drop and then reappear in less than a minute on our frame-relay T3. Verizon is seeing the T3 drop also, but can't find a problem - they've tested up to the demarc, and everything appears to be fine (so they say - we've all been here before, haven't we??) Is there a way we can test the T3 interface in our 7206 to prove that the interface is or is not a part of the problem. Interface statistics appear fine, but the PVC's keep changing...very high carrier transition count looks suspect and points to Verizon.
