    • The invention relates to a method for warming up a spare process in parallel with an active process in a replicated real-time switching system, in particular in a telephone exchange. The switching system comprises an active control unit (WP) having, permanently or when necessary, a replicating hot-standby spare unit (SP) connected to a common internal message bus, so that the spare unit performs the same processes as the active control unit in parallel. In accordance with the invention, the operation of the active process ( sigma ) to be replicated is temporarily frozen in the active control unit (WP) when the process has no tasks to be performed, the other processes of the active control unit simultaneously being kept in operation. After this a spare process ( sigma ) is created to the spare unit (SP), and the state data ( sigma ) of the active process is loaded into the spare process. Provided that no new tasks have come in during this time to the active process ( sigma ), the warm-up is found successful. The warm-up is found failed if new tasks have come in.
    • 本发明涉及一种与复制实时交换系统中的活动过程并行地预热备用过程的方法,特别是在电话交换机中。 切换系统包括主动控制单元(WP),其永久地或者必要时具有连接到公共内部消息总线的复制热备用备用单元(SP),使得备用单元执行与主动控制单元相同的处理 在平行下。 根据本发明,当该过程没有执行任务时,要复制的活动过程(σ)的操作被暂时冻结在主动控制单元(WP)中,主动控制单元 同时保持运行。 之后,为备用单元(SP)创建一个备用过程(sigma ),并将活动进程的状态数据(sigma )加载到备用进程中。 只要在这段时间内没有新的任务进入积极进程(sigma ),那么热身赛是成功的。 如果新的任务进来,热身者就会失败。

    • A stored-program-controlled local telephone exchange in which internal connections and conference connections are treated as though they were both a combination of an external connection, namely an originating connection and a terminating connection. This is achieved by providing a virtual route (ETV1... ETV60), which is realized by records in a computer memory and which is linked to a call handler (CR1... CRn) and which, from the aspect of the call handler, behaves as a conventional trunk terminal (ET1... ET60). Alternatively, the virtual route can be replaced with two hardware implemented digital trunk terminals which are mutually connected by means of a physical wire connection. In the case of a conference connection, the conference equipment (MJ) is connected to a hardware implemented digital trunk terminal (ETC) which coacts with the virtual route (ETVMJ1... ETVMJX). From the aspect of the call handlers (CR1... CRn), there is formed a barrier (11) over which signalling takes place in an identical manner irrespective of whether the call concerned is an external call, an internal call or a conference call. A group selector (GS) incorporated in the local telephone exchange is influenced by program logic located behind the information barrier (11), without the call handlers being aware of the existence of the group selector.
    • 存储程序控制的本地电话交换机,其中将内部连接和会议连接视为外部连接即始发连接和终止连接的组合。 这通过提供虚拟路由(ETV1 ... ETV60)来实现,该虚拟路由由计算机存储器中的记录实现,并且链接到呼叫处理器(CR1 ... CRn),并且从呼叫处理程序的方面 ,表现为传统的中继终端(ET1 ... ET60)。 或者,虚拟路由可以由通过物理线连接相互连接的两个硬件实现的数字中继终端代替。 在会议连接的情况下,会议设备(MJ)连接到与虚拟路由(ETVMJ1 ... ETVMJX)协作的硬件实现的数字中继终端(ETC)。 从呼叫处理器(CR1 ... CRn)的方面,形成了屏障(11),信令以相同的方式发生,无论所涉及的呼叫是外部呼叫,内部呼叫还是电话会议 。 组合在本地电话交换机中的组选择器(GS)受位于信息屏障(11)后面的程序逻辑的影响,而呼叫处理程序不知道组选择器的存在。

    • User-friendly modifications and restructuring of the data for many line terminating sets and/or system components and abrupt switching of relay operation to the new relay operation program. Central control unit with numerous processors (BP, CP, IOC) which over any half of a doubled bus system (B:CMY) have access to any halves of doubled main storage sections (CMY), the halves of which regularly store identical information. If the memories are not doubled, at least two different memories (LMY, AV) store identical information. During a special operating time individual processors (e.g. BP1, IOC1), a bus system half (e.g. B:CMY1) and several of the memory sections together with a memory of an address management unit (AV) are separated and connected to an autonomous special computer (O&M, BP1, IOC1, AV, B:CMY1, CMY1); in the rest, the previous relay operating program continues to work with the latter's memory sections. In the special computer the data/programs stored therein are modified. After re-unification of the special computer with the rest, the modified program can immediately control the relay operation, so that first only the earlier memory sections of the special computer control the relaying activity until the modified data are copied also into the corresponding other memory sections.
    • 对于许多线路终端机组和/或系统组件的数据进行用户友好的修改和重构以及将继电器操作突然切换到新的继电器操作程序。 拥有众多处理器(BP,CP,IOC)的中央控制单元,其中任何一半的双总线系统(B:CMY)可以访问双重主存储区域(CMY)的两半,其中一半的系统定期存储相同的信息。 如果存储器不加倍,则至少两个不同的存储器(LMY,AV)存储相同的信息。 在特殊的操作时间内,单独的处理器(例如,BP1,IOC1),总线系统一半(例如B:CMY1)和几个存储器段以及地址管理单元(AV)的存储器分离并连接到自主特殊 电脑(O&M,BP1,IOC1,AV,B:CMY1,CMY1); 在其余部分中,以前的继电器操作程序继续与后者的存储器部分一起使用。 在专用计算机中,存储在其中的数据/程序被修改。 在专用计算机与其他计算机重新统一之后,修改的程序可以立即控制中继操作,使得首先只有特殊计算机的较早存储器部分控制中继活动,直到修改的数据被复制到相应的其他存储器 部分。
