基于FPGA的多路E1传输高速RS422业务方案

High speed RS422 transmission scheme over E1 based FPGA

提出了一种高速RS422业务通过多路E1进行传输的设计和实现方案,该方案能够将标称速率为8704kb/s的同步RS422业务映射为5路E1,同时在接收端正确恢复业务数据,实现业务传输,并利用FPGA实现了该传输方案。

A High Speed RS422 transmission scheme over E1 is proposed in the paper. In the presented scheme, synchronous RS422 which nominal speed is 8704kb/s can be transmitted over 5 channels El, and the business recovery is implemented in the receiver. And the scheme is implemented by FPGA.
