宁夏电力通信交换网使用7号信令系统的研究

Study on Using No. 7 Signaling System in Communication Exchanging Network for Ningxia Power Grid

信令系统是通信网的神经系统。随着综合业务数字网的发展和信息高速公路对通信的要求逐步增高 ,宁夏电力通信交换网目前使用的中国 1号随路信令 ,已不能满足程控交换网对信令的要求。7号信令是国际标准化的通用公共信道信令 ,具有传送速度快、信息容量大、应用灵活等优点。本文阐述了宁夏电力通信发展中 ,在交换机中推广使用 7号信令系统的必要性。

Signaling system is the neural system of communication network. With the development of ISDN (Integrated Service Digital Net) and the requirements of information highway to communication,the China No. 1 signaling System used in communication exchanging network for Ningxia power grid can notmeet the demands of program -controlled exchange network for signaling The No. 7 signaling system is a modem standardized,advanced and common- usedpublic channel around the world with the advantages of fast transmission speed, large information capacity and agile application. With the development of communication in Ningxia power grid,the necessity,urgency and scheme of applying No. 7 signaling system in exchangers are set forth in this paper.
