본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명을 설명하기 위한 MX-3턴업 테스트 블록도, 제3도의 (가)는 본 발명에 따른 로컬 턴업시 디지탈 신호 처리기의 연결상태도이고, (나) 및 (다)는 리모트 턴업시 디지탈 신호 처리기의 연결 상태도, 제4도의 (가)는 1대의 MX-3를 점검하기 위한 디지탈 신호 처리기의 연결 상태도이고, (나)는 2대의 MX-3를 점검하기 위한 디지탈 신호 처리기의 연결 상태도.2 is an MX-3 turn-up test block diagram for explaining the present invention. (A) of FIG. 3 is a connection state diagram of the digital signal processor during local turn-up according to the present invention, and (B) and (C) are remote turn-up. Connection diagram of digital signal processor, Figure 4 (a) is a connection diagram of digital signal processor for checking one MX-3, (b) Connection of digital signal processor for checking two MX-3 State diagram.

Claims (1)

MX-3에 내장된 MCU가 멀티플렉서(11), 디멀티플렉서(12), 모니터용 디멀티플렉서(13), 패턴발생기(14) 및 패턴검출기(15)가 내장된 각각의 유니트(DS1,DS3,OIU)를 제어하여 상기 MX-3의 하드웨어 및 라인상태의 정상여부를 판별하되, 로컬 턴업 테스트시 상기 각 유니트(DS1,DS3,OIU)내부의 모니터용 디멀티플렉서(13)를 점검하고자 하는 채널에 연결시킴과 아울러 상기 패턴발생기(14)를 구동시켜 소정의 패턴이 발생되게 한 후, 상기 각 유니트(DS1,DS3,OIU)에 루프백을 가하여 각 유니트(DS1,DS3,OIU)내부의 패턴검출기(15)로 패턴이 검출되게 함과 아울러 그들의 패턴동기여부를 확인하여 동기가 되지 않았을 경우에는 해당 유니트의 하드웨어를 불합격으로 판정하고, 동기되었을 경우에는 소정 횟수동안 기록된 패턴에러수를 드레쉬 홀드값과 비교하여 많을 때 해당 유니트의 하드웨어를 불합격 판정하고, 리모트 턴업시 시스템으로부터 루프백되는 패턴의 에러를 상기 로컬 턴업시와 같이 검출하여 드레쉬 홀드값 이상일때 상대방 시스템의 하드웨어나 연결라인을 불합격 판정하도록 하는 것을 특징으로 하는 다중통신 중계기의 자체 고장 진단 방법.The MCU embedded in the MX-3 uses the multiplexer (11), demultiplexer (12), monitor demultiplexer (13), pattern generator (14), and pattern detector (15) with built-in units (DS1, DS3, OIU). The controller determines whether the hardware and the line state of the MX-3 are normal, and during the local turn-up test, connects the monitor demultiplexer 13 inside the units DS1, DS3, and OIU to the channel to be checked. After driving the pattern generator 14 to generate a predetermined pattern, a loopback is applied to each of the units DS1, DS3, OIU to pattern the pattern detector 15 inside each unit DS1, DS3, OIU. If the synchronization is not performed by checking the pattern synchronization, if it is not synchronized, the hardware of the unit is determined to be unsuccessful. If it is synchronized, the number of pattern errors recorded for a predetermined number of times is compared with the threshold hold value. When the unit Determining the failure of the hardware, and detects the error of the pattern looped back from the system at the time of remote turn-up as in the case of the local turn-up to determine that the hardware or connection line of the counterpart system if the threshold hold value or more is failed. Self-diagnosis method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
