[asterisk-users] Merlin Legend PRI not quite there yet

Greetings list,
I have been beating around a problem for a while now and decided
after weeks of searching I would try the list once again.
The jist is this:
Merlin Legend connected to verizon via a 100D (PRI) card. Works great.
Asterisk connected via a crossover'd TE110P to a second 100D (PRI) in
the legend.
The green light on the TE110P comes on, but we have a red alarm on
the 100D card.
Asterisk can see RED ALARMS on the PRI when we busy out the 100D card
on the legend system. Asterisk also shows the alarms disappear when
we restore the 100D card on the legend. We reset the card and run a
loopback. After the loopback the red alarm is gone for roughly 4 to
10 minutes then turns back on. I believe this to be a "threshold" of
errors being reached which triggers the red alarm.
Checking the status of the 100D card shows it has a RED alarm and
error events:
Checking the error events shows
MIS (Misframes) 250
Slips: 57
Errored Seconds: 255
Bursty Seconds: 017
Severely Errored Seconds: 255
Frame Slips: 255
We have replaced the crossover cable. (Using standard 1-5, 2-4, 4-2,
5-1 pinout).
We have replaced the 100D with a known good unit
We have replaced the previous T100P with this new TE110P
We replaced the server with a supermicro P4 server.
All the results are the same.
QUESTION is where can I go from here? What can we do to correct this
problem? Could this be a timing setting on the legend switch?
Anything would be appreciated, even a snicker or two about our still
using merlin legends will be accepted. :-)
Sterling.
