Abstract

PURPOSE:To simplify the constitution of the incoming-call display part of a mobile station by transmitting a calling signal, synchronizing with a calling signal from a switchboard, from a base station to the mobile station after a radio circuit is connected with regard to radio-coupled telephone sets. CONSTITUTION:A calling signal, once sent out of switchboard 3, is detected by calling signal detecting circuit 11 and at the same time, control circuit 12 is put into operation to generate tone signals f1 and f2. At mobile station 2, detectors 23 and 24 detect signals f1 and f2 and control circuit 29 sends tone signal f3 to base station 1. On receiving signal f3, base station 1 stops the transmission of signal f2. Oscillator 13 generates signal f1 synchronizing with the calling signal from switchboard 3. Through detector 23 and AND gate 27, this signal puts incoming-call display unit (bell) 28 into operation. Therefore, the need for an oscillator for intermittence at the station 2 side is eliminated and bells of stations 1 and 2 can be put into operation synchronizing with each other.
