1720 serial int. up/up

Hi all

One of my friends encountered a situation when the leased line connected the 1720 serial int. was removed the

#sh int s0/0

command is still showing the int as up/up even when the telco modem/line is disconnected.

He changed the WIC card with a new one but the same scenario.

Anybody has any ides what could be wrong here? Appreciate any ideas...thanks

Re: 1720 serial int. up/up

Do you have 'no keep' under the serial interface config?

Can you post the serial interface configuration?
