S-1240系统自1986年12月在安徽省合肥市第一个开局使用后,迄今已有两年多了。在两年多时间中,S-1240系统由上海贝尔电话设备制造公司(SBTEMC) 生产并开通了约70余个局所,其中包括市话局、长话局、长市合一局等。同时,在质量上也有很大的进步。众所周知,任何一种交换机系统,要使其软硬件成熟,均要经过一段改进的历程。S-1240系统由于其系统庞大,功能齐全,在国际上首次使用了全分散的控制方式,因此必然要付出很大的努力来改进其软硬件。近年来的改进可以分为系统本身的发展和在开局、维护使用中的
It has been more than two years since the S-1240 system was first used in Hefei, Anhui Province in December 1986. For more than two years, the S-1240 system has been produced and launched by Shanghai Bell Telephone Equipment Manufacturing Co. (SBTEMC) with more than 70 offices, including the local telephone exchange, the long distance telephone exchange and the Changyi Joint Council. At the same time, there are also great improvements in quality. As we all know, any kind of switch system, to make its hardware and software mature, have to go through a period of improvement. S-1240 system due to its large system, full-featured, for the first time in the world to use a fully decentralized control, it is bound to have to make great efforts to improve its hardware and software. In recent years, the improvement can be divided into the development of the system itself and in the beginning, to maintain the use of
