县电业公司在13个乡镇共有13个营业厅和14个变电站,营业厅为10M带宽0A办公业务,接口类型为FE以太网,要求汇聚到电业公司。各乡镇变电站要汇聚到武鸣调度网,每个变电站至少要求1路RS232串口,用于电力调度网,且要求考虑未来发展视频监控业务,预留2M带宽专用视频业务FE以太网接口。经分公司多次组织技术论证,最终确定按如下思路设计技术方案:在
County Electric Company in 13 towns a total of 13 business offices and 14 substations, business offices 10M bandwidth 0A office business, the interface type FE Ethernet, requiring convergence to the electric company. The township substation should be brought together to Wuming dispatch network, each substation requires at least 1 RS232 serial port for power dispatching network, and requires consideration of the future development of video surveillance services, reserve 2M bandwidth dedicated video services FE Ethernet interface. The branch repeatedly organize technical feasibility studies, and ultimately determine the following ideas to design technical solutions:
