b32e0ab602 Implementation of RX level squelch (for A-Netz and B-Netz) 
Use -S <dB> for setting RF level or use -S auto for auto level.

When squelch closes, audio is muted. If squelch is closed for some
seconds (depending on network), call is released. (RF loss condition)

The previous loss detection has been removed

bb64c6b3ba AMPS: Add DTX support 
When DTX is enabled (-S dtx=2 or 3), a missing SAT tone causes the receiver
to mute audio and insert a low level of comfort noise.
Also the missing SAT tone will not cause the connection to be terminated.
