摘　　要：随着网络规模的扩大和用户需求的增加,大客户的概念有所扩展,总部-分支的网络应用越来越广。采用何种接入技术,降低组网、维护成本,满足客户实际需求是当前网络建设的焦点。通过对CPOS网络的架构的研究,提出2.5G CPOS网络FPGA设计的总体方案,重点突破2.5G CPOS网络的接入、解析、通道化处理等关键技术的研究和实现,并选用Altera公司的FPGA芯片进行设计实现,加载到FPGA芯片用QUARTUS II信号采集工具Signaltap进行采样验证。With the increase of network scale and requirements of users,the concept of large customers is expanded, and the application of headquarters-branches network becomes become much wider. What kind of access technologies should be used to reduce network maintenance costs and meet customers＆#39; demand is now the focus of network construction. Based on the study of CPOS network architecture, the overall solu-tion of FPGA design for 2. 5G CPOS network is proposed, with emphasis on the breakthrough of key tech-nologies including access, analysis and channel process. Meanwhile, Altera＆#39;s FPGA chip is selected to load onto FPGA chip, thus with QUARTUS II signal acquisition tool Signaltap for sample verification.
