This parameter defines the Mode S address of the internal loop back telegram used by the Ground
Station signal processing board (SPB) for test purposes.
5.4.3.5 Maintenance
Every write access to the online running Ground Station is a maintenance task. The supervisor should
activate the maintenance mode. This indicator notices the monitor users about the maintenance,
which will be performed.
In the ’Information’ text field, the supervisor in maintenance mode can prompt a message to the moni-
tor users. If the ’Information’ field is empty, a default string is written to the ’Information’ text field, if
monitor mode is switched on. Already present text in the field will not be overridden.
