ATM0 is initializing, line protocol is down

Hello,

I just got a Cisco 1721 that is going to replace my functioning SpeedStream 5500 ADSL router. I have purchased the proper ADSL WIC because I had this WIC working at the office on an ADSL line we have there.

Here is the problem. When I do a:

R1#show int atm0

I get:

ATM0 is initializing, line protocol is down Hardware is DSLSAR (with Alcatel ADSL Module) MTU 4470 bytes, sub MTU 4470, BW 800 Kbit, DLY 640 usec, reliability 0/255, txload 1/255, rxload 1/255 Encapsulation ATM, loopback not set Encapsulation(s): AAL5 AAL2, PVC mode

23 maximum active VCs, 256 VCs per VP, 0 current VCCs VC Auto Creation Disabled. VC idle disconnect time: 300 seconds Last input never, output never, output hang never Last clearing of "show interface" counters never Input queue: 0/224/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: Per VC Queueing
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 packets output, 0 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out

So to me this looks like a layer 1 problem because it cannot train the line. Yet when I pull the phone line out of the 1721 the interface stays initializing and does not go to down:

Is this normal? Could the card have busted between my house and work? I have a green WIC1 OK light.

Any ideas what my problem could be?

Thanks,

Thanks for your quick reply but I am afraid I am still in the same situation. The line will not train so the card must have either died on the way home from work today or I am doing something very wrong.

But can someone tell me what the WIC 1 OK led gaurentees?? A green to me would indicate that all the self tests passed and at least on a physical level the card should be good.

It my assumption correct?

Thanks,

Tina

R1#show diag [wic-slot-num]

Your WIC is for ADSL-over-ISDN line. Could be that your office line is over ISDN, while your home line is ISDN-over-POTS? If so, then you need WIC card without -DG in the name.

Kind regards, iLya
