    Functions Loading and saving a configuration • Quick exchange of a device in case of a failure without new configuration • Applying a standard configuration • Backup of a device configuration on portable hardware. An EDS500 500FSD20 modem detects the configuration stick automatically during operation. If the configuration stick is plugged into the device at power on then the configuration is loaded from the stick and copied to the internal configuration memory.
