    • In an ATM switching module, expansion interfaces are connected in pair to an ATM switch to respectively operate in active and standby states. When another ATM switching module is installed and a connection is established between an expansion interface of standby state and the newly installed ATM switching module, a process sets the standby state expansion interface in hot-standby state, and holds off incoming ATM cells destined for the hot-standby state expansion interface until the connection is ready to accept cell traffic, whereupon the hot-standby state expansion interface is switched to active state, whereby the ATM switch and an ATM switch of the another switching module constitute a multi-stage configuration. The processor is arranged to update the routing table according to internal state of the ATM switch so that, when a call is to be established for an incoming ATM cell, the header of the cell contains a plurality of fields containing routing data respectively associated with different stages of the multi-stage configuration.
    • 在ATM交换模块中,扩展接口成对连接到ATM交换机,以分别在主动和待机状态下工作。 当安装另一个ATM交换模块并且在待机状态的扩展接口和新安装的ATM交换模块之间建立连接时,进程将待机状态扩展接口设置为热备用状态,并且保持目的地为 热待机状态扩展接口,直到连接准备好接受小区流量,此时热待机状态扩展接口切换到活动状态,由此ATM交换机和另一交换模块的ATM交换机构成多级配置。 处理器被安排为根据ATM交换机的内部状态来更新路由表,使得当要为入局ATM信元建立呼叫时,小区的报头包含多个字段,包含分别与不同的路由数据相关联的路由数据 多级配置的阶段。
