Did they loop clean to the NIU or to the portmaster's? We had the same
situation that we finally tracked to the dB level we were seeing on the
line's as they terminated into the PM3's. It was originaly at +1dB,
inside the +2 to -7.5 reported, but caused massive CRC and bipolar
violations to be generated. Switch in this case was a DMS-100. We
got the dB level down to -0.3dB at which point the errors went away
and we have been running okay ever since, about two weeks now. I never
got a response from any Lucent techs on the list or by calling support
as to what dB levels the PM3 likes. If you or the telco can check the
dB level on the line, that is something to do. Every other install
we've done has gone (mostly) as planned so I haven't had to trouble
shoot PRI's very often.
Don't let up on Sprint, and don't be put off by their "We'll have to
charge you if it turns out to be your problem" mantra. I always
ask "Do we get to charge you if it is your problem?", at which point
the tech gets dispatched. :)
