HI
We have an Cisco 2500 series router not configured by me but show strange behaviors of that i loose contact with the router very often however i can not confirm it is due to power shortage or error in transmission at this point but like to investigate what and why it is going down.

Where do i start and what to look for ???
I am leaning toward the possibility that the service provider of T1 is to blame but not sure ...
