我国自主研制开发程控交换机取得了突破性进展。目前,我国公用通信网局用程控交换机总容量的一半为国内生产的设备。国内生产的程控交换机占新增容量的比例去年达到87%,今年将达到90%以上。这中间,由中国自主研制开发的程控交换机在本地网中所占的比例已达14%,去年全国新增局用交换机中有五百多万门是中国自主研制开发的,占当年新增交换机容量的23.3%。据介绍,我国自主研制开发的程控交换机虽然研制开发起步晚,但技术起点高。
China’s independent research and development program-controlled switches made a breakthrough. At present, half of the total capacity of program-controlled switches in China’s public communications network bureau is domestically produced equipment. The proportion of domestically-produced program-controlled switches in the newly added capacity reached 87% last year and will reach over 90% this year. In the middle, the proportion of program-controlled switches independently developed and developed by China has reached 14% of the total number of local networks. Last year, more than 5 million of the total number of switchboards in the country was independently developed and developed by China, accounting for an additional switch 23.3% of capacity. According to reports, although China’s independent research and development of program-controlled switches started late development, but the technology starting point.
