为使通信专业学生更好地理解SDH的网元结构和通道复用原理,设计以典型光传输设备OptiX155/622H实现不同类型网络组建和传输不同类型的信号的实验。实验内容包括OptiX155/622H的功能和用法的介绍,以及基于OptiX155/622H的链形网和环形网组网及E1、IP信号的传输。实验过程分硬件和软件两部分:硬件部分旨在增强学生的动手能力,软件部分实现板卡业务的配置。学生可以在实验基本内容的基础上对自己感兴趣的理论部分做实验的拓展,一方面可以加深对通信信道复用理论的认识,另一方面可以激发学生对通信工程应用的兴趣。
In order to make communication professional students better understand SDH’s network element structure and channel multiplexing principle, a typical optical transmission equipment OptiX155 / 622H is designed to realize experiments of different types of networks to set up and transmit different types of signals. The experiment includes the introduction of the functions and usage of the OptiX155 / 622H, the networking of the chain network and the ring network based on the OptiX155 / 622H, and the transmission of E1 and IP signals. The experimental process is divided into two parts: hardware and software: the hardware part is designed to enhance students’ practical ability and the software part is to realize the configuration of the card service. On the basis of the basic content of the experiment, students can expand their experiments on the theoretical part that they are interested in. On the one hand, they can deepen their understanding of the theory of multiplexing of communication channels and on the other hand, they can arouse students’ interest in the application of communication engineering.
