VWIC2-2MFT-T1/E1 ISDN Problem

Unanswered Question
May 28th, 2010

Hi Experts,

I have a 2911 router runing CME with 2 VWIC2-2MFT-T1/E1 , 2 ports of 1 card are going to be used for data circuits while 2 ports of other card are going to be used for voice T1.

I am able to configure data ports successfully but when I try to configure voice interfares I am having trouble.

1. I don't see a Serial0/1/0:23 interface . Instead I see it as Serial0/1/0:0

2. It does not accept any ISDN comand.

Following is show inventory and controller configuration.

You need the comand..pri-group timeslots 1-24 under te controller you want to use for voice. Once that is configured your "D channel" will b available.

controller T1 0/1/0

pri-group timeslots 1-24

this will autoimatically create..interface s0/1/0:23.

Also don't forget to issue the commands before applying pri-group under controllers:

     !

     isdn switch-type xxxx

     network-clock-participate wic xxxx

     !
