基于四纤环同步数字传输设备割接问题的探讨

Study on the Cutover of Quadruple-fiber-based SDH Equipment

针对当前同步数字传输四纤自愈环复用段保护网上设备的迁改,例行检修等设备需要中断所带来的业务倒接问题,研究了在四纤环上的业务不受影响情况下将节点中断进行相关工作的可行性,以及采用的方法,并分析了四纤环的结构和倒换原理。

The movement of the equipment in the net of SDH quadruple-fiber self-healing ring and routine inspection of equipment would bring intermission of server.This paper studies the feasibility of node intermission and the effective method for implementation.Besides,it analyses the structure of quadruple-fiber and its working principle.
