What data is stored where
The communication server’s data storage system consists of different elements:
• In the Flash components are stored the system software, the boot software and
the configuration data. The contents of the memory are retained even when
there is no power supply.
• In the RAM components (main memory) are stored volatile data that cannot be
saved. It is available only when the system is in operation.
• The EIM card (Equipment Identification Module) contains the system-specific
data (system ID, system type, sales channel, licence code, generation, DECT iden-
tification numbers), IP address of the Ethernet interface on the configuration
server). The contents of the memory are retained even when there is no power
supply.
• The data of applications on the applications server (if an CPU2 applications card
is fitted) is stored on a hard disk.
