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 identifica-
tion numbers, IP address of 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 a CPU2-S applications card is
fitted) is stored on a hard disk.
