我国电信事业的发展是电话热的基础我国电信业曾长期滞后于国民经济的发展速度,成为经济腾飞的一个制约因素。为了改变电信业的落后状况,邮电业的广大职工做出了艰辛的努力。目前我国的公用电话网已基本上实现了自动化、数字化。县以上城市及经济发达地区长途干线主要采用光缆、数字微波和卫星通讯系统。预计到1995年长途电路将达52万路,新增扩建一级光缆线路3.7万公里,建成北京——沈阳——哈尔滨、北京——武汉——广州、上海——杭州——福州、北京——太原——西安等22条光缆干线。同时将建设北沿海、南沿海、沿江三大数字微波干线1.5万公
The development of China’s telecom industry is the basis of telephone hotness China’s telecommunications industry lags behind the growth rate of the national economy for a long time and has become a constraint factor for economic growth. In order to change the backwardness of the telecom industry, the vast number of staff and workers in the telecommunications industry have made painstaking efforts. At present, China’s public telephone network has basically realized the automation and digitization. Long-distance trunk lines in cities above the county level and economically developed areas mainly use optical fiber cables, digital microwaves and satellite communication systems. It is expected that by 1995, the number of long-distance circuits will reach 520,000 and an additional 37,000 km of first-class optical cable lines will be built to build Beijing-Shenyang-Harbin, Beijing- Wuhan- Guangzhou, Shanghai- Hangzhou- Fuzhou and Beijing- - Taiyuan - Xi’an, such as 22 fiber optic cable trunk. At the same time, it will construct 15,000 kilometers of the three major coastal areas along the coast of the sea, along the south coast and along the three major digital microwave lines
