Pau, I'd appreciate very much if you could confirm which signals should […]

The situation you are trying to catch ("the trx is enabled, just after trx_is_usable() starts to return true." || "the trx is disabled, just after trx_is_usable() returns false.") is precisely what S_NM_RUNNING_CHG I itnroduced recently is for. You should be using that one only in that case (you also need to do the checks for the BBTRANSC also, since trx_is_usable() checks both RCARRIER and BBTRANSC).

Please have a look at the commit messages I posted above, they contain a couple examples on how to use the signal.
