Referring to Figure 1, a console (dispatcher point) interfaces a base station with a point-to-point link. Only the console that interfaces with a specific base station 'knows' that base station, i.e. the console can only communicate with that base station because it is aware of the base station type, the type of point- to-point link used, the protocol, the type of radio signalling used by the base station, the encryption type and the encryption key. A console that inter- faces a specific base station decrypts and encrypts messages from and to its base station, and translates voice and data to a common protocol which is dis- tributed to all consoles that share a dedicated local area network (LAN).
