CRC Errors

[jszapipes]

At one of my remote sites i am getting complaints of dropped calls, so i take a look at their router and notice the CRC errors are climbing on one of the serial interfaces at a steady rate. I assumed it was a faulty T1 controller, so i replaced it, but the issue remains. I replaced the cables with new ones, but the problem remains. I called our carrier and had them check the circuit and it checked out good. I have replaced the router, but still, the errors keep growing and dropped calls still persist. I am at a stand still and would appreciate any help!!!!!  Nothing has changed with the configuration (encapsulation, duplex, speed, clock rate, etc...)

Thanks in advance,

Joe

CRC errors == faulty circuit.

Note, you must be present onsite for a BERT test with telco in order to have them at least acknowledge the problem.

Their normal reaction is to deny until pressed with evidence.

Apparently running the test a second time found an issue in the telco equipment. Or they never ran the first test!! Thanks.

Hi Joe,

take loop and perform bert test with carrier i think that will resolve the problem.
