摘　　要：介绍了一种为解决监控中心与数字直放站之间的传输要求而设计的一种E1数据时隙任意插入与同步提取的方案,该设计方案在基于一片E1接口芯片设计的E1数据接口电路的基础上通过FPGA实现,并配合ARM完成时隙的选择性调节。实际环境的试验结果表明:在工程实现中该方案具有良好的工作性能和一定的实际应用价值。This paper introduces a method designed for random insert and synchronous extraction of E1 data slots to meet the transmission requirements between supervision center and digital repeater. This method is accomplished on FPGA with a E1 data interface circuit which is designed basing on a E1 interface chip and achieves the selective adjustment of slots by cooperating with ARM. The test result gained in practical envi- ronment shows the scheme has better performance and potential applications in practical.
