摘　　要：为了在E1链路上能够可靠稳定地传输以太网数据包,提出了一种基于E1链路的高级数据链路控制(HDLC)成帧解帧处理电路。该电路采用HDLC协议在系统发送部分对介质无关接口(MII)发送的以太网数据包进行封装,并通过广域网(WAN)接口发送出去;在系统接收部分再对WAN接口接收的数据进行解封装。仿真结果表明:在发送端以太网数据包通过MII进行发送的情况下,该电路在接收端可以成功恢复出初始的以太网数据帧。In order to transmit ethernet packets over E1 link reliably and stably,a high-level data link control(HDLC)frame-forming and frame-de-framing processing circuit based on E1 link is proposed.This circuit adopts HDLC protocol to encapsulate ethernet packets sent by media independent interface(MII)in the sending part of the system and send them through wide area network(WAN)interface.In the receiving part of the system,the data received by WAN interface is unsealed.The simulation results show that the initial ethernet data frames can be recovered successfully at the receiving end when ethernet packets are sent through MII at the sending end.
