Abstract
본 발명은 전전자 교환기 가입자용 하이브리도 IC시험장치 및 그 시험방법에 관한 것으로 이것은 특히 하이브리드 IC를 별도의 시험용 보드에 실장하지 않고서도 하이브리드 IC 자체시험이 가능하게 한 것이다.The present invention relates to a hybrid IC test apparatus and a test method for a subscriber to an electronic switchboard, which enables a hybrid IC self-test without particularly mounting the hybrid IC on a separate test board.
종래에는 하이브리트 IC 자체시험장비가 없어서 하이브리도 IC를 교환기의 가입자 보드에 실장한 후 그 가입자보드를 시험함으로써 하이브리드 IC 기능을 시험하였으므로 많은 번거로움이 뒤따랐다.Conventionally, since there is no hybrid IC self-testing equipment, the hybrid IC function was tested by mounting the hybrid IC on the subscriber board of the exchanger and then testing the subscriber board.
본 발명은 상기의 문제점을 개선하기 위한 것으로서 하이브리드 IC(10)의 기본 기능감지를 위한 혹-오프 감지회로(50)와, 인테스트 릴레이회로(60)와, 통화전류 감지회로(100)와, 아웃테스트 릴레이 회로(70)와, 극성 반전회로(110)와, 링 공급 및 링 트립감지회로(80)(90)와, 송수신 이득 및 잡음을 측정하는 전송 특성 측정회로(40)와, 전체기능시험용 데이터 및 프로그램이 내장된 마이크로 프로세서(20)로 하이브리드 IC(10)를 로딩시켜 각 감지회로를 통해 하이브리드 IC(10)의 기본적인 기능시험을 수행한 후 전송특성 측정회로(40)를 통해 전송특성 기능시험을 수행하게 한 것이다.The present invention is to improve the above-mentioned problems, the lump-off detection circuit 50, the in-test relay circuit 60, the call current detection circuit 100, for detecting the basic function of the hybrid IC 10, Out test relay circuit 70, polarity inversion circuit 110, ring supply and ring trip detection circuit 80 and 90, transmission characteristic measurement circuit 40 for measuring transmission and reception gain and noise, and full function The hybrid IC 10 is loaded into the microprocessor 20 in which test data and programs are embedded, and after performing basic functional tests of the hybrid IC 10 through each sensing circuit, the transmission characteristics are measured through the transmission characteristic measurement circuit 40. The function test is performed.
