基于MPC852实现SDH光网络设备网元管理功能

介绍了使用MPC852处理器既完成SDH（同步数字体系）设备光业务和公务业务的盘控器功能又实现SDH网元管理功能，具体描述了网元DCC（数据通道转换器）通信接口硬件设计、网元管理模块与盘控器模块间的数据交换机制以及网元管理设备可靠性策略的设计，使用这种方法实现网元级网管系统既降低了成本，又提高了SDH网元管理设备通信的可靠性，最后通过具体的工程组网应用验证了本方案应用于实际工程的良好效果。

Implementation of Element Management Function of SDH Optical Network Equipment Based on MPC852

This paper introduces the implementation of optic and official modules of Board Control Termi- nal, and Element Management Unit of SDH network based on MPC852,and describes mainly the hardware design of DCC communication interface of Network Element, the mechanism of data switching between Element Management Unit and Board Control Terminal, and the reliability strategy of Element Management Equipment. The application of this approach not only reduces the cost intelligent communication reliability of SDH Element by applying the method to actual projects. of Element Management System, but also improves Management Equipment. Finally, good results are achieved by applying the method to actual projects.
