Abstract

1. 청구 범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

사설교환기에 관한 것이다.It is about a private exchange.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

국선으로 디지트에 대한 다이알 신호를 출력하는 동안 발신가입자회로와 스위칭회로를 차단하는 사설교환기에서 국선 다이알 송출시의 노이즈 제거 방법을 제공한다.The present invention provides a method for removing noise during CO line dial transmission in a private exchange which cuts off a subscriber subscriber circuit and a switching circuit while outputting a dial signal for a digit to a trunk line.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

사설교환기에서 발신가입자가 국선으로 다이알 신호를 송출하는 방법은 상기 발신가입자의 훅크오프에 의해 통화로가 형성되어 디지트에 대한 다이알신호가 송출될 동안 상기 발신가입자의 가입자회로를 스위칭회로로부터 분리함을 특징으로 한다.In the private exchange, the calling subscriber transmits a dial signal to a trunk line by disconnecting the subscriber circuit of the calling subscriber from the switching circuit while a call path is formed by the hooking-off of the calling subscriber and the dial signal for the digit is sent. It features.

4. 발명의 중요한 용도4. Important uses of the invention

국선 다이알 송출시 발신 가입자로 유입되는 노이즈를 차단하기 위해 이를 구현한다.This is implemented to block the noise flowing into the calling subscriber when the CO line dial is transmitted.
