Proper command to use for modifying E/M card


I'm attempting to configure MOH on my CME, from a live source as documented here:

I've got the CD player ready, have had the adapter cable built to connect it to the E/M card, but I'm not sure how to modify the E/M card with the voice-port command. The card is on a 2851 router, and it is installed in the location marked "HWLC1". I am totally unfamiliar with this aspect, an am not sure what I should use (eg., voice-port 1/1/0, etc).

Any help woudl be greatly appreciated.


Re: Proper command to use for modifying E/M card

Once your router detects the VIC, it should appear in the config (sh run) as voice-port a/x/y. a, x and y can vary based on slot, port etc.

to configure e/m to support MOh, you will need to do the following,

voice-port 1/1/0 <-- e/m port 0 on slot 1.


signal immediate

operation 4-wire

input gain

dial-peer voice 1 pots


port 1/1/0 <-- this needs to be e/m port

ephone-dn 1

number 3333

moh out-call

Re: Proper command to use for modifying E/M card

Hi, I have the following listed in my show run:

voice-port 0/0/0:23


voice-port 0/1/0


voice-port 0/1/1


voice-port 0/2/0


voice-port 0/2/1


voice-port 0/2/2


voice-port 0/2/3


voice-port 0/3/0


voice-port 0/3/1


voice-port 0/3/2


voice-port 0/3/3

So just so I understand, 'slot 1' (the middle number of the three) would refer to the actual location on the router marked HWLC1? So likewise, slot 2 or 3 would refer to the locations HWLC-2 and -3?

Re: Proper command to use for modifying E/M card

I see that you have many voice ports and you are trying to identify which port is e/m. You can do a show voice-port a/x/y to find out which port is e/m.

You can also do a sh voice-port summary to find out the interface types on each vic.

From your port numbering, you seem to have ,

a. 1 port t1 vwic on slot 0,

b. 2 port vic on slot 1,

c. 4 port vic on slot 2 and

d. 4 port vic on slot 3.

Most likely your slot 1 (2 port vic) should be e/m.

Do a show voice-port 0/1/0 or (0/1/1) to find out what kind of interface it is.

Re: Proper command to use for modifying E/M card

The router is in a different location, but I wrote down what I have:

HWLC0: VWIC2-1MFT (T1 interface card)

HWLC1: VIC2 e/m card

HWLC2 & 3:VIC2-4FXO cards (not in use)

Thanks for the advice!!
