Those errors from the router in my experience are 99/100 times a carrier issue. Occasionally it can be your extended demarks or patch cables, and on that 100 th time it could be hardware but I’d go with the carrier as a first look

Over the last few months, I've had sporadic D channel errors. Am I correct in suspecting carrier issues? Typically, if it's a problem on our end, we'd see other errors like unregistered gateways, etc.

I don't have any more log details from the 6608 ports, but the one port on our 3945 had this information in the logs at the time: 


Jul 13 2012 04:33:58.335: %CONTROLLER-5-UPDOWN: Controller T1 0/0/0, changed state to down (AIS detected)

Jul 13 2012 04:35:17.644: %MARS_NETCLK-3-CLK_TRANS: Network clock source transitioned from priority 10 to priority 1 

Should I be looking in CallManager logs for more information at this time?
