基于大数字微波和虚拟环技术的链式传输网成环改造

描述了在如海岛等光缆资源匮乏的特殊地理条件下，运用大数字微波设备，结合虚拟环技术，对单向链式传输线路进行双纤单向通道保护环的环网改造的方案设计及基于华为T2000网管平台的业务配置及实现。同时针对微波段易受环境干扰，易于产生误码的特性，对业务配置进行一致路由法改造，减小了恶劣天气下微波段误码对环网的影响，提高了环网的安全性与合理性。实践证明改造后的环网工作正常，提升了网络安全性，该方案具备推广价值。

The Cyclization Reconstruct Based on Microware and Virtual Ring on Chain type Transmission Network

It＇s introduced a Cvclization Reconstruct by using digital microware in lack of optical cable condition like island. The virtual ring technic is used to build Two-fiber unidirectional path protection ring on HUAWEI T2000 monitor. By consistent routing, problem made by error code of microware is solved and security of network is improved. The reformed network worked well and the solution illustrated a good prospect of application and extension.
