    Hi,

    Any help on the below will be appreciated. I tried to have the same configs
    for the interfaces and the DCE ends are on the 2504 router but I'm still
    having some dramas.

    Here's my output from the 2 routers:

    Can someone pls advise why one of the serials is down?

    Thanks,
