PS2: Is this behavior defined somewhere in 3GPP specs?
Normally the BTS (not BSC) is responsible for declaring a radio link failure event by sending CONN FAIL IND over the A-bis/RSL. Doesn't Ericsson RBS 6xxx send us such a message? The radio lonk failure is declared "based upon either the error rate on the uplink SACCH(s) or on RXLEV/RXQUAL measurements of the MS" (see 3GPP TS 45.008 sections 5.3). The Connection Failure Criterion is configured via the A-bis/OML.
