PS3, Line 11: and since notification to RSL Emulation happens async, it
: can happen (verified) that ChanRqd message from BTS arrives and is
: handled before we register the RACH req into the ConnectionTable
one option that could be investigated is to temporarily pause processing of any RSL events until you have received the fn from L1CTL and installed the expectation in the ConnectionTable.
We already have this kind of logic as 'dchan_suspended' in RSL_Emulation.ttcn. You could also have something like a chan_rqd_suspended and set/unset that via procedure port.
I'm not saying it must be done that way, I'm just stating this is a proven option to work around such races.
