Another thing to look at is how they are testing. If
you have a full T1 then you can have them run a 'round
robin with multi pattern' stress test. This will
break any marginal component. Some telco's will tell
you that you can't test that way on a frame circuit,
but that is only if you are not running all 24
cahnnels.
Also, are they doing head to head testing, this will
force the LEC to actually plug into the smartjack and
test from there. But there is charges to this one if
they don't find a problem.
