ATM interface issues

Hi Guyz,

I am having a very strange issue with my 887 Branch router type at different locations that suddenly loose connection on the WAN ATM0 interface.

A router reboot does not solve help bring up the interface but when the ATM0 cable connection is unplugged and plugged in again, it works.

Does anyone have a hit as to what this could be? I am experiencing it more and more often.

see below for the device details.

Well, what puzzles me is why this is happening all over a sudden on different devices.

I thought more of a configuration change on the provider ATM cloud that i am also trying to investigate at the moment.

thanks.

will keep u posted.
