ABSTRACT:
A system and method for allowing intercom and multiple voice channel communication within a private telephone system employing a private base station and a multiplicity of standard cellular terminals is disclosed. Full duplex intercom communications between two users within the private telephone system may be facilitated by use of two half-rate channels, one channel transceiver on even-numbered TDMA transmission frames and another channel transceiver on odd-numbered transmission frames, both from respective terminals to a private base station, which mediates the communication therebetween. Multiple voice channels are also provided within the private telephone system, allowing two users on two separate channels to communicate with respective remote wireline users simultaneously.
