Well, at least you're openly honest about it ;-)  Such honesty will 
make rehab that much easier for you. :-)

What error message did the sender see?

Well, if you were to turn off TracingMask and SessionTracing to 0xFFF 
then we'd be able to see those HDLC frames that caused the FCS error in 
the first place, hopefully they'd give us an idea of what the problem 
was.

But what it looks like is that we only caught part of the HDLC frame 
(post-page message signal, PPS), and this threw the timing off, and the 
sender did not repeat the signal as much as it should.  Maybe there was 
a disconnection.

Is this error frequent?
