PURPOSE:To increase connectors regardless of a base unit by deciding response timing by the connector and comparing a response signal from the connector by a slave unit so as to select an optimum radio speech path by the slave unit. CONSTITUTION:At connectors 11 and 13, the response timing is deviated by response timing decision parts 12 and 14. When a slave unit 15 receives the response signal deviating this response timing, it is informed of a response signal comparison part 16, and the response signal comparison part 16 compares the response signal from the connector 11 with the response signal from the connector 13, judges which connector is suitable for establishing the radio speech path and selects any one of the connectors. Thus, since the slave unit 15 compares the plural response signals and selects the radio speech path, the control of the base unit can be omitted and the connectors can be increased regardless of capacity in the base unit. |
