    Hello,

    I have a cisco 2821 with a HWIC-1ADSL running.

    When I give a "show interface atm0/0/0" command I see CRC-errors (about
    30/min):
    (also note that there are no input errors)

    router#sh int atm0/0/0
    ATM0/0/0 is up, line protocol is up
    Hardware is HWIC-DSLSAR (with Alcatel ADSL Module)
    MTU 4470 bytes, sub MTU 4470, BW 1016 Kbit, DLY 500 usec,
    reliability 255/255, txload 1/255, rxload 40/255
    Encapsulation ATM, loopback not set
    Encapsulation(s): AAL5 AAL2, PVC mode
    23 maximum active VCs, 256 VCs per VP, 1 current VCCs
    VC Auto Creation Disabled.
    VC idle disconnect time: 300 seconds
    Last input never, output 00:00:00, output hang never
    Last clearing of "show interface" counters never
    Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 153
    Queueing strategy: Per VC Queueing
    5 minute input rate 162000 bits/sec, 1 packets/sec
    5 minute output rate 1000 bits/sec, 2 packets/sec
    88183 packets input, 125414082 bytes, 0 no buffer
    Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
    0 input errors, 29 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
    48726 packets output, 3586484 bytes, 0 underruns
    0 output errors, 0 collisions, 0 interface resets
    0 output buffer failures, 0 output buffers swapped out

    But when I give the command "show atm pvc 8/48" now I don't see them:

    router#sh atm pvc 8/48

    Any suggestions about what the problem can be? I already tried another IOS,
    but that makes no difference.

    And here is the output of a "show dsl interface atm0/0/0":

    some CRCs on an ADSL line are ok, if you have a shared phone line make sure
    you have filters on all other devices connected to your ADSL line.
