【摘要】 随着现代社会对网络带宽需求的越来越大,光缆网络铺设成本越来越低廉,各大网络运营商开始大规模引进光网络。为了配合建设上海市政府“百兆进户、千兆进楼、T级出口”的网络覆盖,上海电信城市光网项目应运而生。城市光网项目以EPON技术为基础建设初期的光网络。在对PON技术及设备进行了基本了解,并深入研究了电信FTTx相关业务的业务开通流程以及上海电信现有业务自动激活系统之后,设计了EPON网元自动激活模块的北向接口以及南向接口。北向接口部分详细介绍了自动激活系统与服务开通系统之间的交互以及北向接口参数。南向接口部分通过两家厂商私有协议的对比,建立了统一的接口规范,结合电信FTTx业务开通流程需求,设计EPON网元自动激活子模块。在现有自动激活系统的基础上实现各子模块的自动激活流程。本文研究工作的意义在于,该自动激活模块在上海电信自动激活系统中启用,将大大缩短PON相关业务开通时间,提升用户感知度,增强电信竞争实力。自动激活成功率稳定维持在95%以上,证明该EPON网元激活模块工作稳定性很好。然而随着电信业务需求的不断变化,该激活模块需要进一步研究以适应新的需求变化。更多还原

【Abstract】 For the requirements of large network bandwidth and the cost of fiber optic cable network’s construction less and less, the network carriers such as China Telecom start to build lage-scale optical networks. The Shanghai Government proposes the request that "Fast into the household, Gigabit into the floor, the T-class export network coverage" and then the City Optical Network project comes into being in Shanghai Telecom. The project use EPON technology for the early network infrastructure.The Southbound interface of the EPON network element automatically activation module as well as the Northbound interface is designed after a basic understanding of the PON technology and equipment and an in-depth studying of the FTTx related business processes of Shanghai Telecom and the existing Business Automically Activation System.The section of designing Northbound interface introduce interaction between the automatic activation system and the provisioning system with paramenters in details.The section of designing Southbound interface an uniform interface is eatablished from comparison of the two vendor-proprietary protocols. The EPON network elements automatic activation sub-modules are designed with requirements of FTTx business process, which can make the automatic activation of businesses come out on the basis of exsiting Automatic Activation System.The significance of this study is, using the automatic activation of the module in the Shanghai Telecom Automatic Activation System will greatly shorten the turn-on time,enhance the user perception,enhance competitive strength of Shanghai Telecom.Automatic activation success rate remained stable in90%proves that the EPON network element activation module works well. However,the demands for telecom services changing,the activation module requires further study in order to adapt to the new changes in demand.更多还原
