NM-16AM module question in my cisco 3660

hi,

I have 3 of these modules.

with 1 module, when I configure a line and I connect to the line I get only a black screen.

when I do the exact same thing with another module, (configure a line on the 2nd module) it works fine.

my question is, how can I know if a module is broken or not functional. can this happen?

any advice on how to find out if a module is broken or if I single modem in the module is dead.

thank you.

also when I use debug modem and I call a modem that works fine I get this

11w6d: Modem 5/14 Mcom: in modem state 'Dialing/Answering'

11w6d: Modem 5/14 Mcom: in modem state 'Incoming ring'

11w6d: Modem 5/14 Mcom: in modem state 'Waiting for Carrier'

but when I don't get this I know in advance that it's not going to work and that I'll get just a black screen.

any advice please?

thank you.

Re: NM-16AM module question in my cisco 3660

To identify a functional module , we need to look at the front panel LED of 3660 router. If READY 0, 1, 2, 3 is blinking green it indicates,it indicates the functional module is installed in the slot.If this LED is OFF, it indicates the slot is empty or the module is not functional. For more info on 3660 MAR router, refer the following Link.
