c2f14834e5 Rename dbm0 (level) to speech (level)
In mobile communications we use speech level instead of milliwatts.
The deviation (FM) is always based on speech level, not on 1 milliwatt.

87a21a285a NMT: Assign traffic channel for outgoing and incoming calls
This way the control channel stays available for other (idle) phones.

No more loss of coverage for other phones, when a call to a mobile is
made.

It is still possible to define a combined control+traffic channel.
(e.g. for single channel setup)

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
