I have a T1 at a remote office where the users are complaining of lag.
I get 22ms ping (which is typical) to this site, but after the clearing
counters about 12 hours ago... it looks like a lot of errors.
Does this typically mean something in particular to point me in the right
direction?
Is it possible this router (or the T1 card in it) is bad?
Or is this definitely a carrier problem... who I am still waiting for a call
back from.

as 139/255.
