我国市话长期发展缓慢,设备紧张,不能满足社会需要,导致用户小交换机大量增加。据统计,1976年至1981年间,全国市话交换机年平均增长率为6.9%,而用户小交换机年平均增长率为11.8%。1982年,全国市话交换机总容量为232.3万门,用户小交换机容量为276万门,二者之比为1:1.2,少数城市的比例高达1:3以上。北京市用户小交换机容量约为市活的两倍,并以每年3万门以上的速度增长。

Long-term development of our country’s local telephone slow, equipment, can not meet the needs of society, resulting in a substantial increase in users of small switches. According to statistics, from 1976 to 1981, the annual average growth rate of local exchangers was 6.9%, while the average annual growth rate of small island exchanges was 11.8%. In 1982, the total capacity of local exchangers was 2.233 million and the number of users’ minor exchangers was 2.76 million, a ratio of 1: 1.2. In a few cities, the ratio was as high as 1: 3. Beijing’s subscriber switchboard capacity is about twice as large as that of the city and has grown at a rate of more than 30,000 gates per year.
