Async Dialback on 1841 w/WIC-2AM not working

Oct 21, 2005 1 Replies

Hello group,



I am trying to configure async callback on my 1841 with WIC-2AM. The dialin works well, but for some reason, the callback script is not being executed, the debug looks like this:


000079: *Oct 20 11:58:16.335 PCTime: CHAT0/1/0: no matching chat script found for 040284140
000080: *Oct 20 11:58:16.335 PCTime: CHAT0/1/0: Dialing using Modem script: d0efault-d0ials0cript & System script: none
000081: *Oct 20 11:58:16.335 PCTime: CHAT0/1/0: process started
000082: *Oct 20 11:58:16.335 PCTime: CHAT0/1/0: Asserting DTR
000083: *Oct 20 11:58:16.335 PCTime: CHAT0/1/0: Chat script d0efault-d0ials0cript started
000084: *Oct 20 11:59:16.431 PCTime: CHAT0/1/0: Chat script d0efault-d0ials0cript finished, status = Connection timed out; remote h ost not responding

Do you see anything in the config below that might not make sense ? It seems to me that, for some reason, the chat script is not tied to the line/interface...

Thanks for any help in advance. Regards, Naz



From the looks of it, this is not a configuration problem, but just your basic modem trainup problem. You might try using a dialing chat script that caps the WIC-AM modem in V.34 (+MS=V34.)

For troubleshooting this, I would recommend reverse telnetting to the WIC-AM line, then manually testing different AT strings and dialing the remote modem, till you get a connection that looks stable. The AT commands are documented at
