Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
교환기 시스템의 트렁크 채널 테스트 방법.How to test trunk channel of exchange system.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
디지탈 트렁크를 사용하는 교환기 시스템에서 채널 루프백 경로를 이용하여 디지탈 트렁크의 포트를 테스트한다.In an exchange system using digital trunks, the ports of the digital trunks are tested using the channel loopback path.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
채널 루프백 경로를 이용한 디지탈 트렁크의 테스트 방법이, 채널 테스트명령 수신시 테스트데이타발생수단과 해당 채널의 디지탈트렁크를 연결하는 과정과, 루프백모드신호를 송신하여 디지탈트렁크의 해당 채널에 대한 루프백을 형성하는 과정과, 형성된 루프백 경로로 테스트데이타를 송신하는 과정과, 테스트데이타와 루프백경로를 통해 수신되는 데이타를 비교하여 동일할 시 정상 채널로 세트하고 상이할 시 비정상 채널로 세트하는 과정으로 이루어진다.The method of testing a digital trunk using a channel loopback path includes connecting a test data generating means and a digital trunk of a corresponding channel when receiving a channel test command, and transmitting a loopback mode signal to form a loopback for a corresponding channel of the digital trunk. And a process of transmitting test data through the formed loopback path, and comparing the data received through the loopback path with the test data and setting them as normal channels when they are identical and as abnormal channels when they are different.
4. 발명의 중요한 용도4. Important uses of the invention
교환기시스템에서 디지탈 트렁크의 유지보수를 위하여 내부적으로 각 채널별로 루프백 테스트할 수 있어 채널의 이상유무를 용이하게 테스트할 수 있다.For the maintenance of digital trunks in the exchange system, loopback tests can be performed for each channel internally to easily test for channel abnormalities.
