Dear all
I have a 1721 router with WIC-1T connected to framerelay network, when the modem is powered off and then powered on again serial interface becomes down/down and not becomes up again except i unplug & plug the serial cable connecting the modem and the router.
I changed everything; router, WIC-1T, serial cable & modem; and the problem still exist.
Anyone has any idea about that.

hi
can you revert back the exact ios code which you are running in this router ?
Since you have already changed the cable,card & modem may be the possible problem can be with the IOS code coz of some unknown/known bug.

hi
Can you try add a new floating static route in place of those backup commands under the serial interface ?
just remove these command backup delay 5 60
backup interface BRI0 from the serial interface and try configuring ip route 0.0.0.0 0.0.0.0 bri0 10.
After doing this can you try the same exercise which you were doing earlier and check whether your serial port comes active (up/up) instead of down/down as mentioned in your earlier mail..

Hi
Thank you first for your valueable recommendations
I did that before, i removed the configuration of BRI at all and i maintain the configuration of the serial only.
and the same problem exist.
