C-Netz: --ms-power defines power level (not P-bits)
...
Also the level 8 can be selected. Actually level 6 is selected, but
reduced to 8 when making a call.

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.

C-Netz: Added list of base station names and IDs
...
Automatic polarity detection is now done by using the polarity of last
transmitted message. We cannot use two base station IDs anymore, to
detect the polarity. Now we deal only with the defined base station ID.

C-Netz: Correctly synchronize time stamp of SpK to OgK
...
Even if the SpK is not used (yet), it must count time stamp (bit_time) so that
SpK keeps in sync with the OgK, until frames are received from mobile station.
