Abstract

본 발명은 교환기의 가입자 선호 시험 회로에 관한 것으로, 특히 다수의 교환기로 구성된 교환국의 가입자 선로 상태 시험에 적합한 시험 방법에 관한 것으로, 가입자에게 통화로를 제공하거나 가입자 선로를 시험하기 위한 회로를 구성해 주는 다수의 교환 단위 캐비넷(22∼24)과, 상기 다수의 교환 단위 캐비넷(22∼24)을 제어하여 각 교환 단위 캐비넷(22∼24)에 연결된 가입자 선로를 시험하는 글로벌 교환 단위 시스템(21)으로 구성되어, 글로벌 교환 단위 시스템을 통하여 교환 단위 캐비넷에 연결되어 있는 가입자 선로를 중앙 집중적으로 시험할 수 있으므로, 교환 단위 캐비넷마다 가입자 선로 선로 시험부와 시험 용 터미널을 설치해야 하는 문제점을 해소해 주고, 시스템 운용 상의 신뢰도를 향상시켜 주는 효과를 제공한다.The present invention relates to a subscriber preferred test circuit of an exchange, and more particularly, to a test method suitable for the subscriber line status test of an exchange station composed of a plurality of exchanges, comprising a circuit for providing a subscriber line or testing a subscriber line. The master controls a plurality of exchange unit cabinets 22 to 24 and a plurality of exchange unit cabinets 22 to 24 to test a subscriber line connected to each exchange unit cabinet 22 to 24. It is possible to centrally test the subscriber lines connected to the exchange unit cabinet through the global switching unit system, thus eliminating the problem of installing the subscriber line test unit and test terminal in each exchange unit cabinet. It provides the effect of improving the reliability of system operation.
