PURPOSE:To reduce the number of connectors by applying the talking connection between a telephone set and a telephone line via the connector while calling function and calling function and transmission function of in the other telephone set are stopped. CONSTITUTION:When a telephone set B making a call completes the talking and a handset is returned, an on-hook signal is generated, a transmission section 9 is operated under the operation control of a control section 14 and end of call signal is sent through a radio line with a reception antenna 8 of the connecter A via a transmission antenna 10. Then the end of call signal sent from the telephone set B to the connector A via a radio line of a control channel is supplied to the reception antenna 8, a reception section 5 and a control section 7 of the connector A. When the control section 7 detects the end of call signal, the control section 7 in the connector A generates a call inhibition/release signal, it is sent to the telephone set B via the transmission section 3 and the transmission antenna 4 to be reached by all the telephone sets B in the standby state. |
