SDH语音调度在冶金行业中的应用

Application of SDH Audio Scheduling in Metallurgical Industry

从SDH入手,针对此数字传输系列下的数字中继线技术,结合首钢公司语音调度系统联网项目,阐述了SDH在冶金行业语音调度网络的应用,介绍了SDH下最常用的E1数字接口模式语音调度网络,并指出了基于SDH的数字中继组网调度模式的必要性。

From the SDH, aiming at digital trunk line technology under the digital transmission series and combining with the Shougang Corporation audio scheduling system networking project, the paper sets forth the SDH application in metallurgical industry audio scheduling network, introduces most commonly used E1 digital interface mode audio scheduling network in SDH, and points out the necessity of digital relay network scheduling model based on SDH.
