I have a question about the different between 2 crc errors
ADSL circuit has packet loss, when I enter show dsl int atm 0/0/0.
The crc Errors and Header Errors are 0.
This is good.
When I enter show inter atm 0/0/0.
The crc value is incrementing when packet loss occurred.
What is/are the differece between 2 crc?

The other day while troubleshooting I had a DSL circuit that had huge CRC and header errors on the sh dsl interface atm0/0/0; it ended up being the providers circuit. SNR went from 9db to 19db after they 'cleaned' the circuit and errors went away.
