摘要
SDH(Synchronous Digital Hierarchy,同步数字传输体系)是一种将复接、线路传输及交换功能融为一体、并由统一网管系统操作的综合信息传送网络。SDH可实现网络有效管理、实时业务监控、动态网络维护等多项功能,能大大提高网络资源利用率、降低管理及维护费用、实现灵活可靠和高效的网络运行与维护。
本论文在第一章的绪论中主要介绍了论文的研究背景、SDH的传输原理和特点、SDH的应用与发展趋势;第二章对C市概况简介;第三章介绍了C市电信局本地网网络现状;第四章详细介绍了C市电信局SDH传输网络结构设计方案;第五章介绍了SDH网络保护方式的选择与设计;最后对论文工作进行了总结,并提出了下一步研究的设想。其中第一章为原理性论述,第三、四、五章是本论文研究工作的主要体现。
关键词:SDH;同步光网络;综合信息传送网络
Abstract
SDH (Synchronous Digital Hierarchy, synchronous digital transmission system) is a kind of multiplex, transmission and exchange function ., and by the work management system prehensive information work. SDH can achieve the efficiency work management, real time monitoring, work maintenance and other functions, can greatly improve the utilization rate of cyber source, reduce management and maintenance costs, the realization of flexible and reliable and work operation and maintenance.
This thesis in the first chapter of the introduction mainly discusses the research background, the transmission principle and characteristics of SDH, SDH application and development trend of the second chapter of the C city; profiles; the third chapter introduces the C City munication work status; fourth chapter describes in detail the C City munication Bureau SDH work structure design scheme; fifth chapter introduces work protection measures selection and design; at the end of the paper, and the next step research. The first chapter discusses the principle of, third, the four or five chapter is the research work of this thesis mainly embodies.
Keywords: SDH; synchronous work; integrated information work
