Abstract

본 발명은 통화로를 갖는 사설교환 시스템에 있어서 주장치측 가입자와 원격단말가입자측 상호간 호출과 호출에 응동하여 다양한 모드로 통화로가 구성되는 원격동기장치에 관한 것으로 2회선의 통화로에 음성주파수 대역인 300-3400 HZ 의 상측 또는 하측파대에서 시분할된 원격제어 신호를 송신하거나 수신하는 것에 의하여 가입자간에 전화 또는 방송을 위한 통화모드가 일제 또는 부분적으로 선택될 수 있도록 된 음성주파수 대역을 이용한 시분할 방식의 원격동기장치에 관한 것이다.The present invention relates to a remote synchronization device in which a call path is configured in various modes in response to a call and a call between a host subscriber and a remote subscriber side in a private switching system having a call path. Time division method using a voice frequency band in which a call mode for telephone or broadcasting can be selected in whole or in part by transmitting or receiving a time-division remote control signal in the upper or lower band of 300-3400 HZ. It relates to a remote synchronization device.
