【摘要】 ISDN业务在当前的电信网络中应用广泛,因此在NGN网络中实现ISDN业务非常必要。一号数字用户信令——DSS1是ISDN业务实现的基础,本文分析了在NGN网络中实现DSS1的必要性,并对NGN网络中实现DSS1信令系统的原理进行了详细研究,提出了DSS1信令系统的实现模型,最后对DSS1的实现过程进行了详细介绍。更多还原

【Abstract】 Integrated Services Digital Network(ISDN) service is widely used in current telecom network,so to carry out ISDN service in the Next Generation Network(NGN) is very necessary.Digital Subscriber System No.1(DSS1) is the basic of carrying out ISDN service.This paper analyzes the necessity of implementation of DSS1 signalling system in the next-generation-network.And it also analyzes in detail the principle of implementation of DSS1.Then the typical DSS1 signalling system architecture is given,and how to carry out DSS1 is introduced in detail finally.更多还原
