Claims (2)

CPU 및 스위칭회로를 구비한 사설 교환시스템의 트렁크 회로에 있어서, 전용회선(T, R)와 스위칭 회로간의 음성신호를 중계하기 위한 음성통화로부(100)와, 전용회선(T, R)상에 링신호를 공급하기 위한 링거(110)와, 상기 링거(110)의 출력인 링신호가 전용회선(T, R)에 송출되는 것을 제어하기 위한 링릴레이(120)와, 상기 링릴레이(120) 작동시간 동안 음성통화로부(100)로 유입되는 링신호 잡음을 제거하기 위한 뮤트용 릴레이(121)와, 상기 링 및 뮤트용 릴레이를 (120, 121)를 구동하기 위한 릴레이 구동수단과, 상기 링거(100)의 출력인 링신호로 부터 임펄스 형태의 링동기신호를 발생하기 동기검출 수단과, CPU로 부터 인입되는 링송출용 데이터를 상기 링동기 검출수단의 링동기 신호에 일치시켜 상기 릴레이구동 수단에 인가하는 데이터 전송수단으로 구성함을 특징으로 하는 링다운 타이회로의 링동기방식.In the trunk circuit of a private switching system having a CPU and a switching circuit, an audio call path section 100 for relaying a voice signal between the dedicated circuits T and R and the switching circuits and the dedicated circuits T and R are provided. A ringer 110 for supplying a ring signal to the ringer, a ring relay 120 for controlling the ring signal output from the ringer 110 to be transmitted to the dedicated lines T and R, and the ring relay 120 Mute relay 121 for removing ring signal noise introduced into the voice call path unit 100 during the operation time, relay driving means for driving the ring and mute relays 120 and 121; The relay detects an impulse-type ring synchronization signal from the ring signal output from the ringer 100, and the ring transmission data input from the CPU matches the ring synchronization signal of the ring synchronization detection means. It comprises a data transmission means applied to the drive means Ring synchronous type with ring-down tie circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
