Abstract

이 발명은 AETB-M(Analog Emergency Transfer Board-M)보드의 기능시험을 위한 인터페이스 장치에 관한 것으로, AETB-M보드를 시험하기 위해 보드단위의 자체기능을 시험하면서 보드의 이상유무를 신속히 검사할 수 있는 인터페이스 기능을 제공하기 위해, AETB-M보드(10)의 원하는 채널을 선택하기 위해 단말기로부터 채널선택 정보를 입력받으면 릴레이 드라이버/릴레이 회로(11)에 연결된 AETB-M보드의 채널을 선택하기 위한 채널선택회로(12), 20Hz의 링 신호를 입력받아 AETB-M(10)의 링 신호 송출기능을 시험하기 위한 20Hz 링 신호 검출회로(13), 상기 채널선택회로(12)와 20Hz 링 신호 검출회로(13), 피시험체인 AETB-M보드(10)와 가입자 단말①, ②에 연결되어 서로를 연결시켜 주기 위한 릴레이 드라이버/릴레이회로(11)로 구성된 ECCB(Emergency Common Control Board)에 관한 것이다.The present invention relates to an interface device for the functional test of the AETB-M (Analog Emergency Transfer Board-M) board, to test the board's own functions to test the AETB-M board, and to quickly check the board for abnormalities. In order to provide the interface function, the channel selection information is input from the terminal to select the desired channel of the AETB-M board 10 and the channel of the AETB-M board connected to the relay driver / relay circuit 11 is selected. 20Hz ring signal detection circuit 13 for testing the ring signal transmission function of the AETB-M 10 by receiving the channel selection circuit 12 and the 20Hz ring signal, and the channel selection circuit 12 and the 20Hz ring signal. An ECCB (Emergency Common Control Board) composed of a relay driver / relay circuit 11 connected to the detection circuit 13, the AETB-M board 10 under test, and subscriber terminals ① and ② to connect with each other. will be.
