Abstract

본 발명은 사설교환기의 전용성 자동시험 장치 및 방법에 관한 것이다.The present invention relates to an automatic test apparatus and method for a private exchange.

종래에는 사설교환기의 전용성 회로를 시험하는 경우 운용자에 의하여 전용선을 시험하였으므로 전용선 회선에 대한 점검을 주기적으로 신속하게 수행할 수 없어 전용회선을 신속하게 유지보수 할 수 없게되어 전용선의 신뢰성이 저하되는 문제점이 있었다.Conventionally, when testing the dedicated circuit of a private exchange, since the operator tested the leased line, the inspection of the leased line cannot be performed quickly and periodically, so the maintenance of the leased line can not be performed quickly. There was this.

본 발명은 사설교환기의 전용선들을 주기적으로 자동시험하여 시험결과정보를 운용자에게 제공하여 주므로, 전용선에 대한 유지보수를 신속히 할 수 있어 전용선의 신뢰성을 향상시킬 수 있다.The present invention is to periodically test the leased line of the private exchange to provide the test result information to the operator, it is possible to quickly maintain the leased line can improve the reliability of the leased line.
