RF channel release skipping T3109
/* GSM 04.08 gives us two options for the abnormal * chanel release. This can be either like in the non-existent * sub-lcuase 3.5.1 or for the main signalling link deactivate * the SACCH, start timer T3109 and consider the channel as * released. * * This code is doing the later for all raido links and not * only the main link. Right now all SAPIs are released on the * local end, the SACCH will be de-activated and right now the * T3111 will be started. First T3109 should be started and then * the T3111.
