| 摘 要： | 数字数据网(DDN)是基于光纤数字电路,通过引入复用、交叉连接节点构成的,主要为满足非话音业务需要的传输网络。利用日益发展的数字电路,采用DDN技术,是目前满足那些要求传输时延短、通过量大的数据业务的一种较好的办法。本文扼要地介绍了发展我国DDN的总体技术设想,包括网络结构、网络业务、网络同步和网络管理控制。

| Abstract: | DON is the transmission network comprising digital multiplexing and cross-connect nodes based on digital optical fiber cables, with the aim to meet the demands on ever-increasing non-voice services. Utilization of abundant high-quality digital lines and DON technology is an effective way to meet the demands of short-delay and high-throughput data services. This paper provides the general concept of deploying DON in terms of technologies such as network architecture, network services, network synchronization and network management. |
