Abstract

PURPOSE:To effectively use radio frequency, by using radio frequency of 3 waves, and radio frequency of 2 waves among said 3 waves, in the course of controlling the connection of a radio circuit, and in the course of service between each subscriber, respectively. CONSTITUTION:A master station device 1 sets radio frequency of transmission as the first wave fs' to an outgoing slave station 3, and sends a dial tone to the latter. The slave station 3 sets radio frequency of transmission as the second wave fs, simultaneously tunes radio frequency of receiving to the first wave fs' and receives the dial tone. Subsequently, when an outgoing subscriber 2 dials, a selective signal is transmitted from the slave station 3. The device 1 analyzes the selective signal, and after that, switches radio frequency of transmission to an incoming slave station 4, to the second wave fs. The slave station tunes the radio frequency of transmission and the radio frequency of receiving to the third wave fc and the second wave fs, respectively, in accordance with a calling indication signal. Subsequently, when an incoming subscriber 5 responds, the device 1 stops transmission of the second wave fs, the slave station 4 switches the radio frequency of transmission to the first wave fs', and service between each slave station 3, 4 is exeucted by the first wave fs' and the second wave fs.
