摘　　要：利用包网络传输成本的优势,在现有的以太网 /IP网络上仿真电路业务,可以实现传统时分复用(TDM)设备间的无缝连接,从而保护投资。本文提出了在基于以太网的IP网络上传输E1业务的一种整体解决方案,介绍了适配电路的设计和实现。It is a great advantage for investment protection to emulate circuit switching services over existing packet switching networks, such as Ethernet/IP networks. A protocol with total solution is proposed for seamless transportation of E1 service over IP networks based on Ethernet. The design and implementation of the adaptation circuit is analyzed . The equipment is tested in the real network and is shown practical and economical.
