计算机与通信技术的结合,电话、数据、图象等多种通信业务的飞速发展,使信息网络系统进入到一个数字化、智能化、综合化的新的发展阶段。综合业务数字网(IntegratedServices Digital Network,简称ISDN)就是一种有希望实现上述目标的新型网络系统,是通信网的长远发展方向。目前,一些工业发达国家已把它列为九十年代到二十一世纪初发展信息系统(其中包括国防通信系统)的主要战略目标。本文主要介绍国际上研究和发展ISDN的动向,为了便于说明问题,先对ISDN的基本概念作一简要的介绍,最后对我国、我军发展ISDN提出几点不成熟的看法,供探讨。
The combination of computer and communication technology, the rapid development of a variety of communication services such as telephone, data and image make the information network system enter into a new stage of digitalization, intelligence and integration. Integrated Services Digital Network (Integrated Services Digital Network, ISDN for short) is a new type of network system promising to achieve the above objectives and is a long-term development direction of the communications network. At present, some industrialized countries have listed it as one of the major strategic objectives for the development of information systems in the 1990s and early 2000s, including the defense and communications system. This paper mainly introduces the trend of researching and developing ISDN in the world. In order to explain the problem, we briefly introduce the basic concept of ISDN. Finally, we discuss some immature opinions about how to develop ISDN in our country and for our discussion.
