While commom large volume digital switch systems provide basic voice services , special digital switches are often undertaking critical coordination tasks in some special units , such as police , fire - fighting departments , medical emergency services , factories and ore fields , as well as power systems . these dedicated exchangers used to execute coordination are commonly called digital programmable coordinator ( dpc ) . the small volume dpc ' s introduced in this article are majorly used in power systems 除了通用大门数程控交换系统提供基本的语音服务外，专用的程控交换机在一些特殊部门如公安、消防、医疗急救、厂矿和电力系统中常常承担着重要的调度任务，这种专用的完成调度功能的交换机一般称为数字程控调度机，本文设计的小门数数字程控调度机就主要应用于电力部门。
It is a minitype of pbx with an single chip micyoco as the hardcore , it has four customer and one relay interfaces , a 16 x 16 exchange network , along with a keyboard as input and several leds as output . we can communicate within the local telephone exchange and also with the other phones in the other exchanger 该系统包括了程控交换机的所有基本部件：以单片机为核心的控制系统、四个用户接口、两个中继接口、 8 16交换网络以及信号发生源等，能够实现自动局内呼叫处理、出局呼叫处理以及入局呼叫处理。
The network management can effectively use the network resources , the optimized network telephone traffic flows to . also works as when network overload , can maximum limit display the network the handling ability . it also may take one kind of tool solves the network telephone traffic problem which possibly meets 本论文的工作就是围绕如何有效处理s1240程控交换机话务报告展开,从实际工作应用出发,结合目前程控交换机现状,提出s1240交换机话务收集系统体系结构,并开发调测该系统。
In this paper , it analyses the maintaining and operation software system of order - based c & c08 spcts emphatically , it constructs the database model of simulation system with database technology , analyses and designs the platform of simulation system , disgusses the system model and main flowing 文中重点分析仿真对象基于命令的c & c08数字程控交换机的维护操作软件系统。文中利用数据库技术构建仿真系统数拥库模型，进而分析设计了仿真系统平台，讨论了系统模型和主要流程。
In the paper , firstly , it talks about the stored program controlled telephone switch ( spcts ) technology , computer simulation technology and simulating training system ; secondly , it describes the software construction of spcts , compares the main styles among the maintaining and operation system of spcts , analyses the order - based maintaining and operation system of spcts , by this way , designs and achieves the simulating training system 文中首先讨论了与系统相关的程控交换机技术、计算机仿真技术和仿真训练系统；然后，描述了程控交换机的软件结构，比较了交换机维护操作系统的主要模式，分析了基于命令的程控交换机维护操作系统，进而在此基础上设计实现仿真训练系统。
The system goal to the s1240 program controlled switch telephone traffic reported carries on analysis processing , the telephone traffic reported reflected the telephone network movement unusual situation and the warning situation , withdraw from the massive normal data , further analyzes processing for the attendant , reduces attendant ' s working pressure , guarantees the maintenance work the standard unity 本系统开发了s1240程控交换机话务报告日常工作处理模块,减轻了维护人员日常维护工作量,保证维护工作的质量。本系统开发了s1240程控交换机话务报告话务高峰处理模块,为进一步解决话务高峰时的维护问题打好基础。
Optical relay network technoiogy is to buiidup various teiephone networks by the flexible sdh transmission equipment working with stored program control switches . at present , it has been adopted by most of telecom operators in iocal networks of pstn and becomes an eff6ctive solution to imp the operation cost , improve the qos , as well as faciiitat6 the oam 光中继组网就是利用同步数字体系( sdh )传输设备本身组网的灵活性来配合程控交换机组成各种电话网络，在目前的公共电话交换网络( pstn )中的本地网络中，较多地被电信运营商所采用。
At present the national toll station no . 3 network managements system to the primitive telephone traffic reported carries on only the simple data computation and according to the network level classification , is establishing the time start telephone traffic disposal procedure carries on processing , and forms the general form classification to carry on the output 本文的主要成果有:在资料和开发工具有限的情况下,开发了与s1240程控交换机对接的接口程序模块,为实时处理s1240程控交换机的各种系统报告提供了基础保证。本系统开发了s1240程控交换机报告分拣处理模块,为随后相关系统报告和告警的处理奠定了基础。
Since the early 1990s , when the electronics industry came to the stage of digital technology , china has broken through in high - end series personal computers and servers , large - scale parallel computer systems , chinese electronic publishing systems , large - scale spc exchanges for central offices , mobile communications systems , sdh wdm fiber communications systems , thin route satellite communications systems , new generation digital video terminals , manufacturing technology for 0 . 8 - 0 . 35 m cmos integrated circuit chips , etc 到90年代进入数字技术阶段,高档系列微机和服务器产品、大规模并行计算机系统、中文电子出版系统、大型局用数字程控交换机、移动通信系统、 sdh波分复用光纤通信系统、稀路由卫星通信系统、新一代数字视频终端、 08 ? 035微米cmos集成电路芯片制造技术等，都有突破性进展。
