摘　　要：局用程控交换机是计算机按预先编制的程序控制接续的自动交换机,全称存储程序控制交换机。该系统实现功能如下：主要对局用程控交换机的二进制磁带卸载数据,按照规定格式要求,转化成标准ASCII码格式校验并以文本形式输出,经过内存排序,提供给后续计费模块处理。结果验证了系统控制方案的可行性和正确性,并对系统算法进行分析与改进。系统具有很强的推广价值及实际工程应用前景。Bureau of PBX is the preprogrammed computer program control in automatic exchange, the full name of stored pro-gram control switches. This system realizes the function is as follows：mainly to the public line SPC exchange of binary tape un-install data, format requirements, in accordance with the relevant provisions into standard ASCII format validation and output in the form of text, sort through memory, for subsequent billing module processing. Results verify the correctness and feasibility of the system control scheme, and algorithm of the system were analyzed and improvement. System has a strong promotion value and the actual engineering application prospects.
