以电话网为基础建设窄带综合业务数字网和智能网

电话网是覆盖最广的电信业务网，湖北省内窄带综合业务数字网（Ｎ－ＩＳＤＮ）和智能网（ＩＮ）建设应与ＰＳＴＮ综合考虑，湖北省Ｎ－ＩＳＤＮ的发展目标是在２０００年前完成由叠加网向混合网的转变，并实现和各公用网络的互连互联，省内智能网的建设则根据湖北省的实际情况采用ＴＳ／ＳＳＰ／ＩＰ方案，智能网还将实现为与移动网和ＩＮＴＥＲＮＥＴ的结合。

Construct N - ISDN and IN Based on PSTN

The construction of N-ISDN and IN in Hubei province should be considered in combination with PSTN to take advantage of its wide coverage. The goal of N-ISDN development in Hubei is to migrate the overlay network to a hybrid one by the year 2000, and implement the interconnection with other public networks. IN construction should adopt the TS/SSP/IP solution in the light of the reality of the province. IN should also be integrated with the mobile network and the Internet.
