Alarms and alarm configuration
EDS500 500FSD20 modems have an alarm concept to communicate certain error conditions
with an alarm relay, LEDs for display or software signalisation. The individual alarms (referring to
interfaces or the system) are summarised in the system-wide alarm state. The alarms have three
levels of severity.
Alarm level
