上海电报局担负着国内和国际极其繁忙的电报通信业务,为了改变当前电报通信中仍是采用人工转报的落后面貌,自1975年开始在上无十三厂与复旦大学的帮助下,研究采用通用电子计算机进行电报自动转接的新技术,制订了自动转报的技术方案,并于1976年和77年先后装置了两台DJS-131电子计算机,相继配置了32路异步通信转接器、G-3型磁鼓存贮器、多机通信转接器和双机系统监视器等设备。目前已初步建立了可接32路外线(包括座席)自动转报的双机系统。中间试验表明,系统已基本具备各项业务功能,稳定性曾达数百小时,电报转接时间平均3分钟左右,比人工降低十倍,变字率0.04％,比人工下
In order to change the backwardness of manual reporting in current telegraph communications, the Shanghai Telegraph Bureau is responsible for extremely busy domestic and international telegraph communications. Since 1975, with the help of No. 13 Factory and Fudan University, Shanghai Telegraph Bureau General Electronic Computer automatic transfer of the new telegraph technology, developed a technical solution for automatic reporting, and in 1976 and 77 have installed two DJS-131 electronic computer, have been equipped with 32 asynchronous communication adapter, G-3 drum memory, multi-machine communication adapter and dual-system monitors and other equipment. At present, a dual-system system that can automatically report 32 outside lines (including seats) is initially established. Intermediate tests show that the system has basically all the business functions, the stability had reached hundreds of hours, the average transfer time of telegraph about 3 minutes, 10 times lower than the manual, variable word rate of 0.04%, lower than the artificial
