Hello Harald,
Thank you for your responses. I'll change configs with slot-overlapping but
looks like I'm quite far from getting it to work.
Today I found that I have "kernel: wct4xxp 0000:03:02.0: Interrupts not
detected." in syslog. This line was visible only if I load modules manually
(not via systemctl start dahdi)
I heard that it happens on some hardware with Digium cards, I'll try
tomorrow to change PCI slot to avoid sharing one IRQ with USB
devices, maybe disable USB at all. If it doesn't help, I'll try a new
server with different HW.
Now it seems a root cause of the most of problems with communication
between BSC and BTS
Thank you
Babanov Ivan

The pcap file shows that OsmoBSC is sending SABME
requests but that the BTS
never responds to any of them. I would assume that somehow the timeslot
configuration on BTS and BSC side don't agree, i.e. you're sending the
SABME
on a timeslot that the BTS doesn't expect it on.
I remember that the E1 related configuration on the Noika BTS (at least
the InSite)
is relatively complex. Might be best to check all related settings.
