    • An ATM exchange system which handles fixed-length cells, such as an ATM exchange, is designed in such a manner that even when a failure occurs particularly in an interface unit or an ATM switch section, downstream stations can be informed of the failure reliably and that when some failure is detected, counting of a charge counter is disabled to always ensure proper charging. For a method of matching between software and hardware in the ATM exchange system including the ATM switch section having a plurality of line associated sections and firmwares associated with those line associated sections, and a call control processor for controlling the ATM switch section, identifiers of an SVC (Switched Virtual Channel) call and a PVC (Permanent Virtual Channel) call are given to connection information of software on the call control processor, connection data affixed with the identifier of the SVC call is released only on the software on the call control processor during a restarting process of the call control processor, and a request to release the SVC call to all the line associated sections in the hardware of the ATM switch section, whereby matching of path information between the software on the call control processor and the hardware of the ATM switch section is performed.
    • 以ATM交换机等方式处理固定长度的小区的ATM交换系统,即使特别是在接口单元或ATM交换机部分发生故障的情况下,可以将下游站点可靠地通知故障, 当检测到某些故障时,禁止对计费计数器的计数,以始终确保正确的充电。 对于ATM交换系统中的软件和硬件之间的匹配方法,包括具有与这些线路相关部分相关联的多个线路相关部分和固件的ATM交换部分,以及用于控制ATM交换部分的呼叫控制处理器, SVC(交换虚拟通道)呼叫和PVC(永久虚拟信道)呼叫被给予呼叫控制处理器上的软件的连接信息,附加有SVC呼叫的标识符的连接数据仅在呼叫控制处理器上的软件上被释放 在呼叫控制处理器的重新启动过程中,以及向ATM交换机部分的硬件中的所有线路相关部分释放SVC呼叫的请求,由此呼叫控制处理器上的软件与硬件之间的路径信息的匹配 ATM切换部分被执行。
