| 摘 要： | 自从ＩＴＵ—Ｔ完成了ＳＤＨ基本的建议以后，世界上各大通信设备制造厂家集中了大量的．人力和财力开发ＳＤＨ产品，因为这类新一代的产品将会被广泛地应用于通信网，而其硬件比ＰＤＨ设备的要复杂得多，软件量比ＰＤＨ的监控系统要大得多。本文只是从实用的角度出发，对ＳＤＨ系统的产品类型、硬件技术、软件技术、组网技术和同步技术作了概括的介绍。

| Abstract: | The major telecommunication equipment suppliers over the world developed SDH products during recent years by converging vast investment and man-power, as ITU-T finalized the fundanental recommendations for SDH system. SDH products, as a new generation, will be widely deployed in the telecommunication networks. The hardware of SDH products is more complex than that of the PDH equipments and the software lines of code is much more than that of the PDH supervisory system. In this paper, from practical point of view, introduced briefly on the hardware, software, networking and synchronization technologies which were adopted in SDH products development. |
