Abstract

PURPOSE:To use frequencies effectively, by setting a waiting frequency common to all subscribers, and transmitting a specific signal with this frequency in case of a call from a calling subscriber to the other party, and forming automatically a communication line at the base station when the other party responds. CONSTITUTION:When a handset 14 is hooked up to depress a specific key 13 in a calling subscriber station 10, the signal of a frequency FR1 modulated by a call signal fC is transmitted to a base station 5. The base station 5 which receives this signal transmits the signal to many waiting subscriber stations 10, and a controller 4 of a corresponding called subscriber station 10 is started. When the operator recognizes it to hook up the handset 14, the signal of the frequency FR1 modulated by a response signal fa is transmitted to the base station 5. The base station 5 receives this signal to transmit the signal of a frequency FT1, which is modulated by a designating signal fs, through an idle junction line from a transmitter 2. This signal is received by respective controllers 4 of the station, where the key 13 is depressed, and the station where the handset 14 is hooked up, and thus, these stations communicate with signals of frequencies FTm and FRm designated by a transmitter and receiver 3.
