Design and implementation of Ethernet and E1 protocol convertor

Ethernet is widely used in social life. It has become an important infrastructure in the information society. Ethernet over synchronous digital hierarchy (SDH) is regarded as an economical and efficient scheme in the long-distance Ethernet interconnection. This paper considered the design of the Ethernet to E1 protocol converter, based on the frame granularity scheme which takes into account of miniaturization, low power, and low cost. Firstly, the related technology of Ethernet and E1 link is introduced. Then, a system design scheme is put forward based on the Ethernet transmission protocol and the feature of E1 links, and details of each part are discussed. Finally the test methods and results of the system are given. Performance evaluation and tests have validated the feasibility and efficient of the design scheme.
