摘　　要：SDH的全称是同步数字传输体制,是在电信级的网络上得到了广泛应用的传输技术,SDH本身的保护机制相当完备,使得其网络安全而可靠,网管功能技术成熟、组网灵活,并且提供了大容量的高带宽实时透明传输,有完善的自愈体系与支持TDM业务的能力。文中介绍了SDH技术的基本原理、逻辑组成与网络拓扑等知识,并且以实际使用中的OptiX 2500+设备为平台,以一个四点复用段环扩容成五点复用段环为例,在网管服务器上通过参数配置,描述了加点扩容的执行步骤,进行了扩容调试和设备扩容调测,演示了规范的操作流程。Is the full name of SDH synchronous digital transmission system, the level is in the telecommunications network has been widely applied on transmission technology, the protection mechanism of SDH is quite complete, making the network safe and reliable, mature technology, flexible network network management function, and provides a real-time transparent transmission, large capacity and high bandwidth has perfect self-healing system and support TDM business ability. This paper introduces the basic principle of SDH technology, logic and knowledge of network topology, and in the actual use of OptiX2500 ＋ equipment as the platform, with a four-point reuse Duan Huan multiplexing Duan Huan expansion into five, for example, in the network management server through the parameter configuration, describes the steps of the expansion and add, expansion and the debugging and equipment capacity test, illustrates the standard operation procedure.
