Daniel Smith

Level 1

We have gone with the WIC-1AM modem module for our console routers. However, upon dialing in, I get a quick hangup by the WIC-1AM, debugs show the following:

*Apr 10 08:35:29.775: Modem (0/0) DCD Asserted

*Apr 10 08:35:29.799: Modem (0/0) DCD UnAsserted

My config is here:

router#sh run | begin line aux 0

line aux 0

exec-timeout 30 0

password 7 XXXXXXXX

script reset sportster

login authentication modem

modem Dialin

modem autoconfigure discovery

transport input all

stopbits 1

speed 300

flowcontrol hardware

line 0/0/0

stopbits 1

speed 115200

flowcontrol hardware

Thanks in advance for any suggestions!!

Hi Dan,

WIC-xAMs are sensitive to line voltage. So you might want to try a different phone line on it and see how that works.

By the way, if you are reverse-telnetted into the WIC, and now you dial in, do you see RING ?

Also try to dialout from reverse-telnet mode and see if that works.

Thanks and Regards,

Thanks for reply. I was able to do as you suggested, using atdt command to dial my desk phone, and observed RING, when an incoming call was placed. Still investigating, but no progress yet.

I went to another router with WIC-1AM installed and performed a 'debug modem' on that device while attempting a dial in. Here is what I collected:

The 'Unkn protocol' at the top may be the key.
