[H/W] "sh int" on an OC3 interface shows aborts

We're using a Cisco 7304 with an OC3 card installed (7300-2OC3ATM-SMI) running IOS 12.2(20)S10 for remote site connectivity. On the active OC3 (atm3/0) interface (containing 312 sub-interfaces) I am seeing a trickle of CRC errors accumulate but the number of aborts is increasing at a large rate. I have researched the aborts and can't find a good answer of what they are so I was hoping someone had an answer. Do the aborts signify it sees a physical layer issue? Or a higher layer issue? Any help would be appreciated!

It sounds like physical layer issue. Call your ISP or telco to do some loop testing.

You mean demarc. Its short for "demarcation".

But I wouldnt neccessarily replace the cable, sometimes all it takes is to clean the ends (note: with a fibre cleaning kit!), particularly if the environment the service is installed in can be a little dusty.
