Abstract

본 발명은 다중화 시스템에 관한 것으로, 특히 DSI 다중화 시스템에서 트렁크 인터페이스 유니트의 자가 진단을 가능토록 하여 이상 발생 부분을 명확히 알 수 있도록 한 다중화 시스템의 트렁크 자기 진단 장치에 관한 것이다.The present invention relates to a multiplexing system, and more particularly, to a trunk self-diagnosis apparatus of a multiplexing system that enables self-diagnosis of a trunk interface unit in a DSI multiplexing system so that an error occurrence part can be clearly understood.

종래의 다중화 시스템은 채널 유니트의 상태 진단이 가능한데, 에러가 발생되면 채널 유니트의 불량인지 트렁크 인터페이스 유니트의 불량인지를 판단할 수가 없는 문제점이 있으며, 장치 운용중에는 상기와 같은 테스트도 불가능한 문제점이 있었다.The conventional multiplexing system is capable of diagnosing the state of a channel unit. If an error occurs, it is not possible to determine whether the channel unit is defective or the trunk interface unit is defective.

따라서 본 발명은 발생된 테스트 패턴을 제1변성기를 통해 트렁크로 송신하고, 상기 송신되는 테스트 패턴을 피이드백시켜 재변환한 후 그 변환된 신호를 검색하여 프레임 에러 유무를 판단하는 송신 자기 진단수단과, 상기 트렁크로 부터 전송되는 테스트 패텬을 수신하여 기준으로 설정된 테스트 패턴과 비교하여 비트 에러를 판단하는 트렁크 자기 진단수단을 구비하여 진술한 바와 같은 종래 기술의 제반문제점을 해결하였다.Therefore, the present invention provides a transmission self-diagnosis means for transmitting the generated test pattern to the trunk through the first transformer, feeding back the transmitted test pattern, reconverting the signal, and searching for the converted signal to determine whether there is a frame error. In addition, the present invention has solved all the problems of the prior art by including a trunk self-diagnosis means for receiving a test pattern transmitted from the trunk and comparing a test pattern set as a reference to determine a bit error.
