Abstract

본 발명의 목적은 송신모드로부터 통화모드로 전환했을 때 벨이 울리는 것을 방지하는 데 있다.An object of the present invention is to prevent ringing when switching from a transmission mode to a call mode.

이를 위한 구성은 송신모드와 통화모드를 전환하는 모드 전환회로(6)를 제어하는 전환제어회로(7)를 주택내 전송부(4)로부터 주택내 정보의 송신을 종료했을 때 주택 내 전송부(4)내에 설치된 스위치(42)를 오프하는 제어회로(71)와 스위치(42)가 오프된 후 전화교환기(12)가 전화회선(11)의 전압극성을 반전시키기 까지의 소정시간 만큼 통화모드에의 리턴을 지연시키는 지연회로(72)에 의하여 구성했다.The configuration for this is that the switching control circuit 7 for controlling the mode switching circuit 6 for switching between the transmission mode and the call mode ends the transmission of the information in the house from the transmission unit 4 in the house. (4) After the control circuit 71 and the switch 42 which turn off the switch 42 provided therein are switched to the call mode for a predetermined time until the telephone exchange 12 reverses the voltage polarity of the telephone line 11. The delay circuit 72 delays the return of.
