内容简介

　　With the rapid development of the power communications network， the digital synchronization network has become an important part in it and is the key to ensure the performance and quality of network synchronization. With the introduction of various new services and the rapid development of SDH transport network in electric power communications， a quicker development of digital synchronization network has become an urgent need. Therefore， it is imperative and necessary to develop a specification for engineering design of digital synchronization network， which may suit the electric power communications network and meet the future requirements for some time.　　In the development of these specifications， the design experiences in the past decade are summarized. Through extensively referring to the engineering， operation practices and study results， while seeking comments from engineering， operation and management entities concemed， the drafiing panel endeavors to work out these specifications that can reflect the relevant requirements in respect of engineering， construction， and operation management.
