    Abstract: Replacing the functionality of an active digital loop carrier subsystem (DLCSS) or active module with a standby DLCSS or standby module in an IP addressable telecommunication switch is effected by providing only a single externally-known IP address for the module pair and then swapping the IP address of the active module for the IP address of the standby module so that externally-connected devices recognize only the IP address for the module in use. A central network management station in communication with a local nonvolatile memory element controls the IP address swapping.

    Abstract translation: 通过为模块对只提供一个外部已知的IP地址,然后交换IP来实现在IP可寻址电信交换机中更换活动数字环路载波子系统(DLCSS)或主动模块与备用DLCSS或备用模块的功能 用于备用模块IP地址的活动模块的地址,以便外部连接的设备只识别正在使用的模块的IP地址。 与本地非易失性存储器元件通信的中央网络管理站控制IP地址交换。
