This software implements base station protocol of classic mobile phones. With
radio transmitter and receiver connected to one sound card and a headset
connected to another sound card, it is possible to make and receive calls to
and from mobile phone. Currently supported networks:

* A-Netz
* B-Netz (ATF-1)
* C-Netz
* NMT 450 / 900 (Nordic Mobile Telephone)
* AMPS (Advanced Mobile Phone System)
* TACS (Total Access Communication System)
* Radiocom 2000 (French network)
