LED on the radio unit Ascotel DECT

Each radio unit is equipped with 3 LEDs. The radio unit operating state is indicated
by different LED colours and flashing sequences in cycles of 1 second, specifically by
the middle LED on the SB-4, by one of the two outer LEDs on the SB-4+ and by the
two outer LEDs on the SB-8 / SB-8ANT (separately for each AD2 bus). Each character
(G, R or -) corresponds to 1/8 of a second.
Example:
During the synchronization phase GGGGRRRR the LED flashes periodically
1/2 second green, 1/2 second red.

This operating state appears in the following situations:
- during a configuration data upload
- after a system first start (the radio unit is operational only once at least one DECT subscriber is entered in
the numbering plan)
-if in the AIMS Configuration Manager, the parameter "DECT system state " is set to "Passive"
- If a radio unit is not allocated to a Location Area (this may happen after adding a radio unit to a system
with several Location Areas, which is the case when a radio unit has already been set in a Location Area
unequal 0). In this case the added radio unit has to be manually allocated to the selected Location Area.
