>3) I am also asking them to check for bridge traps.

Definitely have them check for this.  We had some bridge tap on a two pair of
wires that was being used by us for a Frame Relay connection.  It was enough to
cause the signal to degrade a couple of times per day and cause a reset of the
connection - took about two minutes to come back up every time.  The telco
(GTE) finally sent someone out at 3 am with a $125,000 UNIX based pattern
testing portable computer to send simulated traffic down the circuit.  Finally
one of the test patterns reproducibly caused the link to die.  The tester was a
stickler who wasn't going to leave until he had tried every possible pattern.
Even though you're not doing the same application, make sure whoever runs tests
on your lines runs every conceivable test...you never know which one will be
significant ahead of time!!
