486d2d5dbe NMT: Fixup assign traffic channel 
dms_call state now belongs to transaction, so it is kept while switching
to traffic channel.

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

The power level is ramped smoothly within 1 ms up or down.

R2000, AMPS and C-Netz turn off power when voice channel is not i use.

C-Netz turns off power between OgK timeslots.

0c9de251be NMT: Implement Hagelbarger Code 
This will correct burst errors of received messages. If the message
is too corrupted, it will be ignored, because some element may not
match then. The digits and line signals are checked for consistency,
since they are repeated serveral times in a message.

7a9762e28e NMT: Disable Supervisory signal during DMS (SMS) transfer and use Timeout

no timeout for Supervisory signal. Instead, the SMS layer will timeout
after some seconds without receiving data.
