摘要： A cordless telephone apparatus having a connecting unit and a cordless telephone set. The apparatus processes a connecting unit call signal sent from the connecting unit and an originating call signal sent from the telephone set by giving priority to either one of the two signals. In a preferred embodiment which gives priority to originating call processing, the connecting unit stops sending a connecting unit call signal and, instead, sends an originating answer signal when an originating call signal with a coincident identification signal is detected during the course of transmission of the connecting unit call signal. The telephone set also sends an originating call signal when a carrier with a coincident identification signal is received. In an alternative embodiment which gives priority to connecting unit call processing, the connecting unit sends a connecting unit call signal on receiving an originating call signal with a coincident identification signal. The telephone set, even during a call originating procedure, stops transmitting an originating call signal and, instead, sends a telephone response signal when it receives a connecting unit call signal with a coincident identification signal.
