Abstract

가정자동화 시스템에 일반전화기의 연결을 릴레이 구동부에 의해 전원공급 또는 중앙처리장치(CPU)에서 제공되는 일반전화기 인에이블 신호단(NP2E)의 신호에 따라 릴레이 구동신호를 발생하고, 스위칭부(253)에서 상기 릴레이 구동부(252)의 출력에 따라 국선(T, R) 또는 일반전화라인(L1, L2), 링신호단(RING)을 선택한다.Connects a general telephone to the home automation system and generates a relay driving signal according to the signal of the general telephone enable signal terminal NP2E supplied from the power supply or CPU by the relay driving unit, and the switching unit 253. According to the output of the relay driver 252, the trunk line (T, R) or the general telephone line (L1, L2), and selects the ring signal terminal (RING).

상기 스위칭부(253)에 의해 통과되는 상기 일반전화기의 후크 온/오프 상태를 감지하며, 전송부에서 일반전화기에 음성 송수선이 용이도록 인터페이싱한다.The switching unit 253 detects a hook on / off state of the general telephone, and the interface transmits the voice telephone line to the general telephone.
