Abstract
A backup memory for constituent packages constituting a transmission system for communication stores a key code identifying the package and configuration data for the package. The constituent packages can be started in a parallel manner based on key code comparison performed between a main CPU and the package so that the time required to start the package is reduced.
Claims9
A backup memory configuration system for use in a communication transmission system having a control package provided with a main CPU for performing control functions of said transmission system, and a plurality of constituent packages provided with respective devices for performing communication functions of said transmission system, and an operation system for supplying configuration data required for operation of the plurality of constituent packages, comprising:
- a plurality of backup memories, each attached to a respective one of the control package and the plurality of constituent packages;
- wherein
- each of the control package and the plurality of constituent packages stores, in the backup memory attached to the package, a key code identifying the package and the configuration data for the package;
- and
- the control package allocates and distributes the key codes to the plurality of constituent packages when the transmission system is started, and allocates and distributes the key code to an individual constituent package when the configuration data is required to be set in the individual constituent package after the transmission system already has been started.
