摘　　要：计费系统JFXT直接从数字程控交换机中提取信息,从而省略了需长期运行的数字采集部件及相应系统、适应长途计费、复式计费及宾馆计费等要求,并能进行实时与定时处理,具有完善的计费、统计、查询、打印及修改参数功能,操作方便、灵活。系统应用了汇编语言、高级语言和数据库语言混合编程及结构化与速成原型法等多种编程技术研制而成。The charge counting system JFXT takes messages directly from the digit private automatic branch exchange. It can satisfy several kinds of demands for charge counting, for example, far distance counting, hotel counting, and so on. It can also handle in time or on time, and it have the perfect fullctions of counting, inquiring, printing and modifying of parameters. The charge counting system JFXT can be used conveniently and effectively. The program of the system is constructed by assembly language, high-level language and database language. The techniques of construction and rapid prototyping are used in the system.
