CCITT No7 신호 링크용 중계선 정합회로Relay line matching circuit for CCITT No7 signal link

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

제1도는 본 발명에 따른 회로도.1 is a circuit diagram according to the present invention.

제2도는 CCS방식의 원리도.2 is a principle diagram of the CCS method.

제3도는 LMA선택 회로의 진리표.3 is a truth table of the LMA selection circuit.

Claims (1)

중계선 정합 회로에 있어서, 수신 데이터에서 멀티 프레임의 동기 비트를 검출하고 동시에 멀티 프레임이 손실되었을 시 손실경보 신호를 생성 출력하는 멀티 프레임 검출부(100)와, 193진 카운트하며 상기 멀티 프레임 검출부(100)의 동기 비트를 받아 리셋하는 카운터부(200)와, 상기 카운터부(200)의 출력신호를 받아 수신 데이터에서 멀티 프레임의 위를 찾아 주고 상기 멀티 프레임 검출부(100)의 손실 경보와 상기 카운터부(200)의 출력을 논리곱하여 CAS와 CCS에서 동시에 사용할 수 있도록 하는 LMA 선택부(300)와, 상기 LMA선택부(300)의 출력을 래치하여 출력하는 출렵부(400)로 구성함을 특징으로 하는 중계선 정합회로.In the relay line matching circuit, a multi-frame detector 100 detects the sync bit of the multi-frames in the received data and simultaneously generates and outputs a loss alarm signal when the multi-frames are lost. The counter unit 200 receives and resets the sync bit, and receives the output signal of the counter unit 200 to find the position of the multi-frame in the received data, and the loss alarm of the multi-frame detector 100 and the counter unit ( And an LMA selector 300 for logically multiplying the outputs of the outputs 200 and simultaneous use in CAS and CCS, and a hunting unit 400 for latching and outputting the outputs of the LMA selector 300. Relay line matching circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
