  • Cisco 2650XM T1 issue

    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 10.0.0.1 255.255.255.0


    This is what I have on the 2650XM:

    Router#sh run
    Building configuration...

    Current configuration : 962 bytes

    controller T1 0/2

    linecode b8zs
    channel-group 1 timeslots 1-24
    !
    interface Serial0/2:1
    ip address 10.0.0.5 255.255.255.0

    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?

    Thanks
Working...
