摘要
RC7216是Raycom公司为实现4路E1线路传输以太网数据而设计的专用集成电路。其设计以RC7216为核心,配以少量的外围元件,通过1～4条E1线路点对点传输10 M/100 M以太网MAC帧数据来实现,并且允许E1线路之间存在一定延迟。介绍了RC7216网桥的硬件结构、工作原理及其应用。
RC7216,produced by Raycom corporation,is an ASIC used to transmit Ethernet frames using 4-E1 channels.Ethernet to 4-E1 bridge can be easily made using RC7216 with a few peripheral circuits.Through 4-E1,it transmits 10M/100M Ethernet MAC frames point-to-point and tolerates a little interval in 4 E1 channels.The structure,principle and application of bridge with RC7216 are introduced.
