发明名称 Radio telephone system control apparatus.
摘要 <p>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 (5, 5 min ) and a radio set of a master apparatus (4). An interphone switch (32) for selecting interphone performances is provided for respective radio telephone sets (5, 5 min ). The slave radio sets of the radio telephone sets (5, 5 min ) are turned OFF when the interphone switch (32) is OFF, and transmitters of the slave radio sets of the radio telephone sets (5, 5 min ) are turned ON. Consequently the connection between a wired telephone channel and the plurality of radio telephone sets (5, 5 min ) can be controlled with a single master apparatus (4) connected to the wired telephone channel. </p>
