数据通信是计算机和通信相结合而产生的一种新的通信方式,它是各类计算机网络的基础。在计算机日益渗透到现代通信系统中的今天,伴随着数据通信这一新的通信业务与技术的发展,针对数据通信系统的测试手段也正在逐步完善。专用的测试设备不断出现,测量仪表的更新换代较之通信发备更快。随着公用数据网的逐步开通和综合业务数字网的建立以及迅速发展的网际互连和高速信息公路。测试对于数据通信系统的研究、开发、生产、安装、调试以及维护使用来说显得愈加重要。
Data communication is a new form of communication that is a combination of computer and communication. It is the basis of various computer networks. Today, computers are increasingly penetrating into modern communication systems. Along with the development of new communication services and technologies for data communication, the testing methods for data communication systems are also gradually being improved. Dedicated test equipment continues to appear, replacement of measuring instruments faster than the communication equipment. With the gradual opening of public data networks and the establishment of integrated services digital network and the rapid development of Internet interconnection and high-speed information highway. Testing is becoming increasingly important for the research, development, production, installation, commissioning, and maintenance of data communications systems.
