摘要
同步复用和映射方法是ＳＤＨ最具特色的内容。本文在简要介绍ＳＤＨ基本知识的基础上，通过对由１４０Ｍｂｉｔ／ｓ信号、２Ｍｂｉｔ／ｓ信号组成ＳＴＭ—１信号的介绍，可使读者对ＳＤＨ有进一步的了解。
The synchronous multiplexing and mapping method is the most characteristic of SDH. This paper first gives a brief intreduction to SDH,and then prewents the STM 1 signal composed by either 140Mbit/s signal or 2Mbit/s signal,from which the reader can have some further understanding of SDH.
