The above apparatus and method are particularly useful for the exchange of sending a ring signal comprising a call recognition signal that selects one of the telephone terminals branched by a third party's call. The apparatus connects and outputs the telephone line to the first port, and the telephone line is connected to the second port in response to an input of a switching control signal, and between the telephone line and the telephone terminal by switching of the switching means. Matching means for matching impedance, self-call signal detecting means for generating a call detection signal in response to a ring call output from the first port of the switching means, when a preset unique call recognition signal is included, and the magnetic And control means for automatically responding to the call by outputting a switching control signal to the switching means in response to the call detection signal output from the call signal detecting means.
