[c-nsp] AAL5 CRC Errors on Cisco 7505 with Enhanced ATM

[Skeeve Stevens]

Anyone know what would be causing these CRC Errors..   It is happening
across a dozen or so PVC's.
Just a hint on what to check, or to look at.

The CRC errors are not being seen on the other end. but they are seeing
packet loss.
