とを特徴とする自動着信選択装置。[Claims for Utility Model Registration] In an automatic call selection device that connects a plurality of terminals to a central office line corresponding to one subscriber number, one of the plurality of terminals is connected to the central office line. A terminal including at least a calling signal detection circuit that forms a closed loop in response to a calling signal given from the terminal, and means for opening the closed loop after a predetermined period of time from the formation of the closed loop. After the closed loop is formed, the terminals are connected to each other via the central office line in such a way that they can receive a PIN number individually representing each of the plurality of terminals sent from the calling party in a PB signal, and each terminal The terminal self-checks whether the received PIN number matches its own PIN number set in advance, and only when the PIN number matches, the closed-loop terminal is configured to take over from one of the plurality of terminals. An automatic call selection device comprising at least means for maintaining the configuration.
