SDH测试平台的设计和实现

Design and Implementation of Bench of SDH Testing

光纤通信是现代信息传输的重要手段.SDH(Synchronous Digital Hierarchy)这种新的传输体制凭借大容量、标准化的优点成为光纤通信的主力.SDH接收/发送器是用于SDH光网络的重要器件.设计并实现了一个自动化的SDH测试平台.平台提供了TCL扩展接口,测试者可以通过接口动态控制SDH过程,实现对SDH接收/发送器的自动化测试.

Fiber communication is an important means of modern information transmission. The new transmission system, SDH, will be predominant in the Fiber communication through its incomparable strong point. SDH Receiver/Sender is one of the most important parts of SDH Fiber Optic Network. This article is to design and implement an automatic bench of SDH Testing. The bench provides TCL extended interface, so the testers can control the SDH process dynamically, and implement the automatic testing for SDH Receiver/Sender.
