congratulations! Now the fun part starts.
Briefly the problem was with ports connections. I did
not expected that
quad-port card requires all ports to be connected. Everything started to
work after I placed dummy loopback connectors to unused ports 3 and 4.
This definitely does not reflect my experience with any of the DAHDI quad-port
cards I have used so far.
After it I was able to check physical link with
e1-prbs-test and was able
to communicate with BTS.
Strange. Maybe some bug or problem with the specific model you use, or
related to the suspected IRQ trouble, or it is a question of clocking? Maybe
the clock reference was configured to (only) use a port that had no signal applied?
