摘　　要：The research and implementation of SDH retiming mechanism were discussed. SDH system is more cost effective than PDH system for high bit rates. In SDH network, transport network channel have timing transparency when transporting PDH signals between two devices having similar interfaces. It is found that the implementation of SDH in the telecommunication networks improves the quality of mobile telecommunication.Synchronization is becoming more and more important with the large deployment of SDH network. Retiming, a new means of timing reference transfer means, is presented. The specifications and implementation of retiming mechanism are also discussed. The benefits that were brought by retiming mechanism are also analyzed.
