ISDN是一种在现有电话网基础上有效、经济地利用网络资源,提供可靠的、智能化服务的技术。它实现了模拟用户线的数字化,将用户线的使用效率提高了一倍。它综合了现有通信网上所有的业务,借助一些智能化的方法,力图通过一个ISDN网络支持所有电信业务的提供,并且进一步实现现有网络中所不具备的一些新的特性。实际上,这种技术实现的目标就是在传统电话网上开展数据、多媒体通信等增值服务。对于我们这样一个拥有1亿门容量、覆盖面极广的世界第二大电话网而言,如何充分利用其现有的资源提供更丰富的应用和业务是一个很重要的问题,不应仅仅停留在提供传统的电话服务的水平上,各种
ISDN is a technology that efficiently and economically uses network resources and provides reliable and intelligent services based on the existing telephone network. It digitizes analog subscriber lines and doubles the use of subscriber lines. It integrates all the services of the existing communications network, with some intelligent means, trying to support the provision of all telecommunications services through an ISDN network, and further to achieve some new features not available in existing networks. In fact, the goal of this technology is to realize value-added services such as data and multimedia communications over the traditional telephone network. For us, one of the world’s second largest telephony network with a capacity of 100 million gates and a very wide coverage, how to make the most of its existing resources to provide richer applications and services is a very important issue that should not stop at Offers a variety of traditional telephone service levels
