Claims (3)
- 통신 시스템에 있어서,전송로를 통하여 수신되는 신호로부터 동기신호가 검출되는지를 판정하고, 데이터 캐리어 검출 제어신호에 상응하는 상태의 데이터 캐리어 검출 신호를 생성시켜 출력하는 전송 모듈; 및상기 전송 모듈의 동기신호 검출 판정 결과를 모니터링하여, 소정의 시간 이상 동안에 연속하여 동기신호가 검출되지 않은 것으로 판정되는 경우에만 전송로 링크 단절을 인식하는 상태의 데이터 캐리어 검출 신호를 생성시키고, 그렇지 않은 경우에는 전송로 링크 연결을 인식하는 상태의 데이터 캐리어 검출 신호를 생성시키도록 제어하는 데이터 캐리어 검출 제어신호를 생성시키는 제어부를 포함함을 특징으로 하는 통신 시스템에서의 데이터 캐리어 검출 신호 생성 제어 장치.
- 제1항에 있어서, 상기 전송 모듈은전송로를 통하여 수신되는 신호로부터 동기신호를 추출하기 위한 동기신호 추출부;상기 동기신호 추출부에서 추출된 동기신호와 초기 설정된 동기신호를 비교하는 비교부;상기 비교부의 비교 결과에 따라서 일치하는 경우에는 업 카운팅을 실행하고, 일치하지 않은 경우에는 다운 카운팅을 실행하는 카운터;상기 카운터의 값이 소정의 임계값을 초과하는 경우에는 동기신호가 검출된 것으로 판정하고, 그렇지 않은 경우에는 동기신호가 검출되지 않은 것으로 판정하는 동기신호 판정부; 및상기 데이터 캐리어 검출 제어신호에 상응하는 상태의 데이터 캐리어 검출 신호를 생성시켜 출력하는 데이터 캐리어 검출 신호 생성부를 포함함을 특징으로 하는 통신 시스템에서의 데이터 캐리어 검출 신호 생성 제어 장치.
- 제2항에 있어서, 상기 비교부는 동기신호를 소정의 비트단위로 분할하고, 분할된 비트단위로 초기 설정된 동기신호의 해당 비트들과 비교함을 특징으로 하는 통신 시스템에서의 데이터 캐리어 검출 신호 생성 제어 장치.
