Operating state of the Aastra DECT radio units
Each radio unit is equipped with 3 LEDs. The operating state the radio units is indi-
cated by different colours and flashing sequences in cycles of 1 s, specifically by
one of the two outer LEDs on the SB-4+ and by both outer LEDs on the SB-8 / SB-
8ANT (separately for each DSI 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.
Tab. 100 Flashing sequences of the status LED on the DECT radio unit
An orange status LED indicates that DECT signalling is active, i.e. DECT sequences
are currently being transmitted between the cordless phone and the radio unit. Ex-
amples:
• With each keystroke on the cordless phone the LED briefly lights up orange.
• During a cordless phone firmware download the orange LED remains lit until the
download is completed.

This operating state appears in the following situations:
- During a configuration data upload
- After a system first-start
- If in WebAdmin in the
DECT
(

) view the parameter
DECT system status
is set to
Passive
- If no location area is assigned to a radio unit - (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.)
