摘要程控交换机（SPC)是存储程序控制交换机，可以说是用电子计算机控制的电话交换机。C&C08数字程控交换机，采用了分级分布式体系结构，是大容量的综合网络交换系统。通过实际的数据配置，实现了局内和局间的语音业务。本文首先对程控交换的基本知识，和C&C08交换机的结构与功能进行介绍。C&C08程控交换机是通过BAM（后管理模块）来管理的，局内用户之间的语音业务可以通过配置计费数据、字冠数据和用户数据来实现。中继数据是用于局与局之间的连接，是运用信令系统来实现的。另外重讲述数据调试，主要内容是局与局之间的数据配置。现在通用的是七号信令，其强大的功能让它的地位无可动摇。对于本实验室的独立模块局，要实现局与局之间的语音业务就要设置自环，这无疑提高了该项目设计的难度。本次设计为C&C08程控交换机局间业务，通过实践调试的过程，对C&C08交换机有了较深入的了解和认识，掌握工程与维护技能，同时对通信网络状况有了深入的认识。关键词：C&C08程控交换机；字冠数据；中继数据；七号信令；自环AbstractExchangetechnologydevelopmentexperiencedfourstages:circuitswitching,packetswitching,fastpacketswitching,labelswitching.Theswitchingnetworktorealizedatacommunication,therearetwomainconditions:oneisusingthepublicswitchedtelephonenetworktransmissionandexchangeofdata,anotheristheuseofpublicdatanetworktransmissionandexchangeofdata.Aswitchincommunicationplaysacrucialrole,informationindifferentlines,terminaloranetworkswitchingbetweenthedistributionprocessarecompletedbyit.SPCisstoredprogramcontrolswitch,canbesaidtobecontrolledbycomputertelephoneexchange.C&C08PBXismanagedbyBAM(afterthemanagementmodule).AndtheBureauofvoiceservicesbetweenuserscanachievebyconfiguringbillingdata,prefixdataanduserdata.RelaydataisusedfortheconnectionbetweentheBureauandtheBureau,whichisachievedbytheuseofsignalingsystem.Nowthecommonthess7makesitthestatusunshakablebecauseofitspowerfulfeatures.Thebureauwillsetself-looptoachievevoiceservicebetweenbureauandbureaubecauseoftheindependentmodulesfortheBureauofthelaboratory.Itimprovesthedifficultyofthedesignofthisprogramundoubtedly.InthispaperthestructureofC&C08switchfunctionanddatadebuggingareintroduced,emphaticallynarratedBureauandtheBureaudatabetweenconfiguration.Keywords：pabx；prefixdata；relaydata；Thess7；self-loop目录摘要..............................................................IAbstract...........................................................II1.绪论..........................................................................................................................11.1本设计目的及意义................................................11.2交换机发展历史..............................................22C&C08程控交换机.....................................................................................................42.1C&C08硬件层次结构.........................................42.1.1主控框配置............................................62.1.2中继框配置............................................72.1.4单板功能..............................................82.2C&C08硬件数据配置.........................................92.2.1硬件系统结构简介......................................92.2.2设备编号..............................................92.2.3HW资源的分配.......................................102.2.4NOD资源的分配......................................103局内语音业务实现................................................................................................123.1局内数据配置......................................
