    I need to connect an Adtran TSU LT to an NM-8a/s installed in a 2800.
    The T1 is a known good, but the router is not connecting. The
    interfaces remain in an Up/Down state. I have used a hard loopback
    plugged into the back of the Adtran, but the router does not see the
    line come nor looped.

    Please help protect my miserable job!

  2. Cocolema,

    You may wish to investigate AdTran TSU LT Troubleshooting with a Cisco

    as well as AdTran TSU LT Documentation:

    and Cisco 2800 Troubleshooting:

    Hope this helps.
