2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

전전자 교환 시스템의 보조기억장치들에 전원이 공급되어 있음에도 불구하고 동작 상태가 비정상이거나, 상기 보조기억장치들로부터 데이타를 읽거나 기록할 때 에러가 발생될 경우 정확한 에러 발생의 원인을 알 수 없었다. 또한 운용자는 에러 발생의 원인을 찾기 위해 보조기억장치를 제어하는 보드의 점검, 보조기억장치를 연결하는 케이블 점검들 여러가지 점검을 하여야 하는데 이 점검의 시간이 장시간으로 이어질 경우에 전전자교환시스템 운용에 큰 장애를 유발시켜 시스템 다운(DOWN)이라는 결과를 가져오는 문제점이 있었다.If the operating state is abnormal even though power is supplied to the auxiliary storage devices of the entire electronic exchange system, or if an error occurs when reading or writing data from the auxiliary storage devices, the cause of the correct error occurrence is unknown . In addition, the operator must check the board that controls the auxiliary memory to check the cause of the error, check the cable that connects the auxiliary memory, and if the time of this check is prolonged, Causing a large obstacle, resulting in a system down (DOWN) result.
