ok, thanks a lot. I've modified the program accordingly. However, still
no success in getting any response from the RBS2308.
On the other hand, on a RBS2401 this works. As soon as you send something
like one SABME per second on timeslot 1, after a couple of seconds the RBS
will start answering using UA and later I-frames.
Now the only mystery remains about the RBS2308.
And somebody (*hint to the list*) will still have to write a OM2000 BSC-side
implementation, basically what we have with abis_nm is for TS 12.21, but for
the proprietary Ericsson OM2000 protocol (details see my wireshark dissector).
But at least for the 2401 we should have all required information now.
Regards,
Harrald
