Abstract

본 발명은 2개의 주파수를 갖는 중계 신호 및 이상 신호를 검출하는 전전자 교환기의 이상 신호 검출 방법에 관한 것으로서, 종래의 기술에 있어서는 이상 신호 검출 기능을 가지고 있지 않아 교환기간 중계 신호 전송중 선로상의 잡음 및 환경의 악영향으로 인하여 신호가 비정상 상태로 되어 규격을 만족시키지 못하는 경우 교환기에서는 신호가 없는 것으로 판정하여 신호를 강제로 종료시키거나, 일부 정보가 누락된 상태로 처리되어 비정상적인 신호 처리가 이루어지는 결점이 있었으나, 중계 신호 검출기가 본 발명과 같은 이상 신호 검출 기능을 가지고 있는 경우에는 상대국으로 이상 신호 검출 결과를 전달하여 신호를 재전송하도록 하여 완전한 신호 처리가 이루어지므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to an error signal detection method of an all-electronic switch that detects a relay signal and an abnormal signal having two frequencies. The conventional technology does not have an abnormal signal detection function. And when the signal is abnormal due to the adverse effects of the environment and does not meet the specification, the exchange determines that there is no signal and forcibly terminates the signal, or processes the signal in a state in which some information is missing, thereby causing abnormal signal processing. However, when the relay signal detector has the abnormal signal detection function as in the present invention, the defect can be improved because the signal is transmitted to the other station and the signal is retransmitted so that complete signal processing is performed.
