Abstract
본 발명은 데이타 전송장치에서의 케이블 시험장치에 관한 것이다.The present invention relates to a cable test apparatus in a data transmission apparatus.
종래 트위스티드 페어 케이블의 시험장치는 송신 데이타 처리부의 출력이 바로 대국 장치이 수신부로 출력되므로 인해 운용자가 각 장치간에 연결된 균형 트위스티드 페어 케이블의 상태를 별도로 시험해 보고 싶은 경우 해결이 안되며, 또한 송신될 데이타가 없는 경우 송신 패리티에 변화가 없어 케이블 시험에 지장이 있을 뿐만 아니라유지보수 기능상에 제한이 있는 문제점이 있었다.The test apparatus of the conventional twisted pair cable is not solved when the operator wants to separately test the state of the balanced twisted pair cable connected between the devices because the output of the transmitting data processing unit is directly output to the receiving unit, and there is no data to be transmitted. In this case, there was no problem in the cable test because there was no change in the transmission parity, and there was a problem in that the maintenance function was limited.
따라서 본 발명은 상기한 종래기술의 문제점을 개선코자 하여 균형 트위스티드 페어 케이블로 데이타, 클럭 및 패리티를 인접장치로 전송하는 시스템에 있어서 오프라인 상태에서 케이블의 이상유무를 판별하기 위한 고정 패턴 발생기능 및 이의 운용자에 의한 선택기능을 보유한 트위스티드 페어 전송방식에서의 고정패턴 발생에 의해 케이블을 시험하므로서, 송신될 데이타가 없는 경우에도 운용자의 명령에 의해 인접장치로 송출시키므로서 송신될 데이타가 실리기전에 미리 케이블시험을 가능케 하는등 유지보수 기능을 강화시키도록 하는 것이다.Accordingly, the present invention provides a fixed pattern generation function for determining whether a cable is abnormal in an offline state in a system for transmitting data, clock, and parity to a neighboring device using a balanced twisted pair cable to improve the problems of the related art. Test the cable by generating a fixed pattern in the twisted pair transmission method that has a selection function by the operator. Even if there is no data to be sent, the cable is sent to the adjacent device by the operator's command so that the data to be transmitted is tested before the data is loaded. It is to strengthen the maintenance function.
