一、前言 云南电力通信事业正处在飞速发展的时期,通信能力迅速增强,技术层次显著提高。目前已初步建成了由基础网(即传输网)、业务网(即程控电话网、无线寻呼网、调度通信网、远动及自动装置数据网等)组成的现代化通信网。网络的基础设施与兄弟省相比基本处在同一水平上,但是,通信的现代化是技术装备和管理现代化的有机统一体,缺 I. Introduction Yunnan Power Communication is in a period of rapid development. Its communications capability has rapidly increased and its technical level has risen significantly. At present, a modern communication network has been initially established which consists of a basic network (ie transmission network), a service network (ie program-controlled telephone network, wireless paging network, dispatching communication network, telecontrol and automatic device data network, etc.). The infrastructure of the network is basically at the same level as the fraternal provinces.
