Abstract

본 발명은 제어된 직류 전원과 브릿지 다이오드를 이용하여 설치가 편리하고 여러 개의 접속 장치의 연결 사용시 가능하도록 한 제어된 직류 전원을 이용한 정전시 국선, 내선 전화기 접속장치에 관한 것이다. 이를 위해 본 발명은 릴레이 구동 수단을 포함하며 제어된 직류 전원을 국선과 내선 전화기의 접속 장치에 공급하여 주는 주장치와; 주장치로부터 출력된 제어된 직류 전원의 유무에 따라 내선 전화기와 주장치의 내선 접속 회로 또는 국선을 접속하는 정전시 국선, 내선 전화기 접속 수단으로 구성된 것이다.The present invention relates to a trunk line and an extension telephone connection device in case of power failure using a controlled DC power supply, which is easy to install by using a controlled DC power supply and a bridge diode, and is enabled when a plurality of connection devices are connected and used. To this end, the present invention comprises a main device including a relay drive means for supplying a controlled DC power supply to the connection device of the trunk line and the extension telephone; According to the presence or absence of the controlled DC power output from the main apparatus, the main telephone line and the extension telephone connection means in the event of a power failure connecting the extension telephone and the extension circuit of the main apparatus or trunk line.
