At the same time , the assay analyzes and illustrates on ochsp and omsp at detail . based on the design of wdm optical net scheme , this assay write o - apsp , which utilizes k1 , k2 that come from osc to sending failure messages of nodes . it also built aps model which grounded on oms 在对wdm光网络结构实现方式详细研究的基础之上,本文编写了光网络自动保护倒换协议( o - apsp ) ,利用来自光监控通道( osc )的k1 、 k2aps倒换字节来传送节点故障信息,建立了基于光复用段自动保护倒换模块。
Chapter five describe the real example of the project of dwdm . related with the project of the east - north loop of fiber transmission system , research the layout of the network , analysis the performance of the transmission and bring out the frondose project of construction , inculde the number of the wave length , the speed of the transmission , the style of he fiber etc . chapter six is the summary of the article 第五章是dwdm技术在通信工程建设中的实际应用,本论文以作者参与的一项具体的工程设计? ?中国移动集团公司建设的东北环光缆传输工程中dwdm技术的运用为实例,根据预测业务发展的要求,从传输性能的分析,到网络的规划,技术上的实现,提出了其具体的建设方案,包括波长数目、传输速率、光纤类型、光复用段、设备制式等。
It must be appreciated and accepted in telecom market , due to its advanced technology reliable performance and high cost performance . a series of technical key problems have been solved , mainly f an overal exhaustive design of the 128k switching network system was presented based on 4k net - chips , with our own intellectual property a 3 level 64k switching net was successfully designed , in which the tlevel consists of l6 4k net - chips and the s - level consists of a self designed single vlsi fpga chip with 560 pins . an optical net interface and an optical multiplexer were designed to carry out the voice transmission and distribution of l28 , 000 users 在研究开发过程中,解决了一系列的技术关键问题,主要有:提出了基于有自主知识产权的4k网片的128k网络系统的总体设计方案;研究设计了tst三级结构64k交换网,其中t级含有16片4k网片, s级由自行设计的、 560pins的、单片大规模fpga实现;研究设计了双机双网双余度的通信控制处理器系统,实现了对用户呼叫、 tst各级网络的控制、报警等各种功能;研究设计了光网接口oni和光复用器omux ,实现了12 . 8万用户话音的传输分配。
