新一代SDH设备中的统计复用与时分复用

摘要

在数据业务即将成为主流业务的背景下，通过对比基于技术融合方式构造的几种新设备，阐述了下一代SDH传输设备的特性，该设备采用了统计复用与时分复用(TDM)结合的方式，既发挥时分复用的可靠性、实时性，又发挥统计复用的高效性.%With the continuous explosion of data service, there are several alternatives in attempting to meet this demand. In this article, we introduce a new SDH transmission technique having two main characteristics， statistics multiplexing and time division multiplex(TDM). So this system has the traits of reliability,real time and validity.
