Abstract

본 발명은 키폰시스템의 각종 아날로그 신호계통의 고장 유무를 진단하는 진단처리 시스템과 관련된 것으로서, 종래에는 이러한 키폰시스템의 각종 회선에서 고장유무를 알기 위해서는 별도의 검사장비로 소정개소를 일일이 검사 진단 하는 수단을 활용하고 있어서 그 진단처리의 효율저하와 불편을 피할 수 없는 것이었다.The present invention relates to a diagnostic processing system for diagnosing the failure of various analog signal systems of a key phone system, and conventionally, means for separately inspecting a predetermined point with a separate test equipment to know whether there is a failure in various lines of the key phone system. As a result, the decrease in efficiency and inconvenience of the diagnostic process was inevitable.

본 발명은 키폰 시스템의 모든 아날로그 접속 회로와 스위치 매트릭스의 고장유무를 시스템 CPU의 고장진단 모드에 따라 자체진단 가능하므로 진단효율성을 증가시킬 수 있다.The present invention can increase the diagnostic efficiency since it is possible to self-diagnose all analog connection circuits and the switch matrix of the key phone system according to the failure diagnosis mode of the system CPU.
