Description

When I'm testing my BSC with a centos BTS + fake trx I'm getting lots of the
messages

<0003> abis_rsl.c:143 (bts=2,trx=0,ts=0,pchan_from_config=CCCH+SDCCH4,state=NOT_INITIALIZED) Abis RSL rx CCHAN: mismatching chan_nr=0x90

It's not 100% reproducible, but it sounds like the BSC' fsm for the timeslot is in a wrong state.
My BSC is on 1.6.0-407-g55d7ee57cf57
My BTS is on 1.2.0.332.2edf

#1 Updated by pespin about 2 months ago

I have seen this locally today, it happens while BTS is not yet ON (because for instance osmo-trx is not available or still not in POWERON state, TS not configured, etc.)
