I currently have serveal 3660-MB-2FE in a HUB and Spoke configuration to ditribute two E1'2 to multipule sites each site along with data using frame-relay. Each remote site has 2 PVC one PVC has 6 DSO's and the second has data
The configuration is working fine the voice quality is good.
What is happening is a times the Q921/Q931 signalling goes complete crazy and fails I have done debug on layers 2 & 3 each and every time it seems to be something differnt. If I do a reload everything seem to work perfectly for a while.
I am at a lost!!!
