Frog, why do you think it couldn't be a clocking issue? I have to admit the
times I've seen this type of behavior it's usually been a clocking issue.
Are there any interface errors other than the interface resets...like CRCs,
etc? Serial interfaces will also bounce when certain error threshholds are
reached in an effort to correct the problem at hand.
Whatever the case may be, sounds like the provider may have to correct
something on their end unless you have misconfigured something or have a
faulty extended demarc or similar (which is usually part of the CPE). Are
you setup to pull clocking from the provider?

Subject: OT: WAN serial interface keep resetting.................
Hi Guys,
This is a real life scenario, HWIC-serial (v.35) is keep resetting. I have
changed the new HWIC , the slot and even a router but still same issue.
I doubt that it could be a clocking issue. This internet here is through
VSAT provider.
has anyone faced this sort of issue?
Because of interface is keep resetting causes flips and a few application
sessions drops. I have observed these soft of flips are around 50-100
interface reset in 24 hours.
Thanks..............
