Abstract

1. 청구 범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

환형 광통신 네트웍의 자동경로 절체 시스템.Automatic path switching system of annular optical communication network.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

155Mbps급 광통신 전송기술 중에 경로 자동 절체(Path Protection Switching)를 요하는 시스템에서 양방향으로의 입출력 신호별 신호성능 상태를 감시하여 가장 안정된 신호를 입력신호로 자동 선택하여 전송서비스를 최적화시키는 신호경로 선택제어 장치를 구현한다.Signal path selection control that optimizes transmission service by monitoring the signal performance status of each input / output signal in both directions in the system requiring path protection switching among 155Mbps optical communication transmission technology. Implement the device.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명은 세방향(EAST, WEST, ADD/DROP)만을 요하며 네트웍 구성 특성상 한 시스템은 두 방향(EAST, WEST)에서 동일한 신호가 입력되어 둘중 좀더 양호한 신호를 신호별로 자동선택하여 입력으로 취하고 출력신호는 양방향이 동일하게끔 보내주므로 대항되는 시스템에서도 자신의 시스템과 동일하게 처리되어도 통신이 가능하게끔 하는 네트웍 구조를 가진다.The present invention requires only three directions (EAST, WEST, ADD / DROP), and due to the characteristics of the network configuration, one system inputs the same signal in two directions (EAST, WEST), and automatically selects a better signal of the two signals as an input and outputs it. Since signals are sent in the same way in both directions, they have a network structure that enables communication even if they are handled in the same way as their own systems.

4. 발명의 중요한 용도4. Important uses of the invention
