Radio telephone system control apparatus and method

Abstract From the Canadian patent

In a method and apparatus for controlling a radio telephone system, a speech channel is established between the slave radio set of a plurality of radio telephone sets and a radio set of a master apparatus. An interphone switch for selecting interphone performances is provided for respective radio telephone sets. The slave radio sets of the radio telephone sets are turned OFF when the interphone switch is OFF, and transmitters of the slave radio sets of the radio telephone sets are turned ON. Consequently the connection between a wired telephone channel and the plurality of radio telephone sets can be controlled with a single master apparatus connected to the wired telephone channel.
