Abstract
청구 범위에 기재된 발명이 기술되 분야 : HDB3 라이코드신호를 사용하는 인테페이스 조건의 전송라인에서 라인 코드에러를 검출하는 장치. 발명이 해결하고자 하는 기술적 과제 : HDB3 라인코드신호를 사용하는 인테페이스 조건의 전송라인에서의 라인 코드에러를 검출하는 장치를 구현한다. 발명의 해결방법의요지 : 본 발명은, HDB3 라인코드신호를 사용하는 인테페이스 조건의 전송라인에서의 라인코드에러를 검출하는 장치에 있어서, 입력되는 HDB3 신호중에서 연속되는 4개 이상의 데이타가 제로임에 응답하여 BPV 에러로 검출하는 "0000"신호 검출부와, V펄스간 B펄스가 홀수개 존재함을 확인하기 위해 V펄스 간의 B펄스의 갯수를 세기 파악하도록 4의 제로 데이타가 부호화법칙에 따라 B00V 나 000V로 부호화된 것을 검출하여 모두 제로로 만들어 주는 BOOV 및 000V 신호검출부로 구성한다. 발명의 중요한 용도 : 코드에러 감출 장치.FIELD OF THE INVENTION The invention described in the claims is described in the field: An apparatus for detecting a line code error in a transmission line in an interface condition using an HDB3 record signal. The present invention provides an apparatus for detecting a line code error in a transmission line under an interface condition using an HDB3 line code signal. Summary of the Invention The present invention provides an apparatus for detecting a line code error in a transmission line of an interface condition using an HDB3 line code signal, wherein four or more consecutive data are zero among input HDB3 signals. In response, the " 0000 " signal detection unit for detecting a BPV error, and zero data of 4 according to the coding law are used to determine the number of B pulses between V pulses in order to confirm that there are an odd number of B pulses between V pulses. It consists of a BOOV and 000V signal detection unit that detects what is encoded in 000V and makes them all zero. Important uses of the invention: code error concealment device.
