<p>
A base station implementation of classic mobile networks.
All these networks use analog voice transmission.
The signaling is done by tones and/or FSK modulated digital messages.
It started with the idea to make a base station for the German B-Netz, but more networks followed.
</p>

<p>
This project is pure software that requires a transmitter and a receiver connected to the sound card of a Linux PC.
A second sound card or ISDN card is used to route calls from and to the mobile phone.
