Are these layer 1 or layer 2 error?

[rleung2001]

I entered the following 2 commands, there is no input error on atm 0/0/0, only 92 crc, but there are lot of crc error on sh dsl atm 0/0/0, are these layer 1 or layer 2 error?

router#sh int atm 0/0/0

ATM0/0/0 is up, line protocol is up

Layer 1 errors. The circuit is not very clean, but probably acceptable. Which DSL FW are you running, from show dsl interface ?

[rleung2001]

What is that header error? I thought it was the layer 2 header.

Try upgrading to FW 3-0-33 from

check docfile for instructions.

here is CRC in Adls encapsulation, low level.
