I feel better having read your post John.... this one ain't so cut'n dry.
The router isn't showing a lot of disturbance, accept for the short PVC
up-time (last time PVC status changed 02:16:23) & the timeouts (Num Status
Timeouts 49). All the LMI traffic is making it back to the interface. It's
not a power issue, the router is does not appear to be resetting (PVC create
time 15:31:26), but a Sho Ver is what we'd really need to see. My bet is
CSU. If there were multiple DLCI's bouncing, I might cry out to the Telco.
Guess we'd really need to catch this thing when it was down... or wait for
it to get a little worse to be sure.
Is this a straight Frame connection (CSU & router). Is their any type of
Telco Mux inline to confuse the router as to when the line is really down
???
Throw parts @ it, try the CSU :-)
