| 摘 要： | 目前大部分IP转E1设备还没有紧致型外围器件互联接口（CPCI）,这里采用RC6105作为多路E1传输以太网的转换芯片,提出了一个带CPCI接口的四路E1传输一路以太网数据的设计方案,使设备通过CPCI总线与工控机无缝连接。介绍了基于CPCI的多路E1传输以太网的整体解决方案,涉及到网络物理接口器件（PHY）和介质访问控制器（MAC）的标准媒体独立接口（MII）连接,帧映射通用成帧规程、以太网帧封装映射及重组还原问题。

| Abstract: | Most IPoverE1-equipment has no CPCI interface.This paper,with RC6105 as conversion chip,proposes a design with CPCI interface in which four E1 channels transport one ethernet data.Thus the equipment and industrial controllers could be seamlessly connected through the CPCI bus.This paper describes an overall solution for CPC-based multi-E1 channel transporting ethernet data,which involves the PHY and MAC equipment connection related to the MII port,frame-mapped generic framing procedure,ethernet frame encapsulation mapping,reorganization and recovery. |
