    Hi. I use a Cisco 1700 router with a T1 WIC. The link has been flapping for
    a few days and now I no longer get traffic. When I unplug all cables from
    the WIC, reload the router and run 'show interfaces serial 0' I get:
    Serial 0 is down, line protocol is down
    I also get the alarm led yellow.
    My question is: Does "Serial 0 is down" (no administratively keyword) mean
    that the WIC died? Thanks for your help.

    No. It means there's nothing plugged into it. Or that there is
    something seriously wrong with the ckt (because it will normally be
    up/down as opposed to down/down). Loop it up and have the telco test
    the ckt.
