TOPIC: Cisco 2650XM T1 issue

Cisco 2650XM T1 issue 7 years 10 months ago #36961

Hello. I am having trouble bringing up a T1 on a 2650XM router. I am using a VWIC-2MFT-T1 card in the 2650. The other device is a
Cisco 7206. If I pull out the VWIC-2MFT-T1 and put it in a 1721 the T1 comes right up, so it seems the card is ok and the 2650 requires something additional in the code.

This is what I have on the 7206:

controller T1 6/0
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24

interface Serial6/0:0
ip address

This is what I have on the 2650XM:

Router#sh run
Building configuration...

Current configuration : 962 bytes
version 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname Router
no network-clock-participate slot 1
no network-clock-participate wic 0
no aaa new-model
ip subnet-zero
ip cef
controller T1 0/2
framing esf
clock source free-running
linecode b8zs
channel-group 1 timeslots 1-24
interface Serial0/2:1
ip address

The carrier detect light is green on the 2650 WIC. The status of the interface is up/down. I can use the same config on the 1721 to bring the circuit up.

Anyone know what I am missing here?
