Abstract

PURPOSE:To inform the state of a carrier at an incoming call to a master station by using an answerback signal as a nonmodulation carrier and switching the length of its transmission time. CONSTITUTION:A switch section 2 connects an antenna 1 and a reception section 3 by using a signal S1 from a radio control section 5 in the state of call standby state. In case of the calling, a master transmission section signal is demodulated by the reception section 3 from the antenna 1 through the switching section 2 and the result is input to the control section 5. The control section 5 discriminates whether or not the inputted signal S2 is a call to its own station and in case of the call signal, an answerback signal is to be sent. In sending a signal (a) for the call for from the master station, the state of the carrier is sent through a status switch 6 corresponding to the consecutive length of the answerback signal as shown in figures b, c and the master station discriminates the status of the carrier depending on the length of the answer- back signal.
