Aastra 470 as of R1.2
syd-0337/1.2 – R1.2 – 11.2011
6. 5. 3. 4 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. 102 Flashing sequences of the status LED on the DECT radio unit
An orange status LED indicates that the DECT signalling is active, i.e. DECT se-
quences are currently being transmitted between the cordless phone and the radio
unit. Examples:
• With each keystroke on the cordless phone the LED briefly lights up orange.
• During a cordless phone software download the orange LED remains lit until the
download is completed.
State Cycle Meaning

Red Error:
R R R R R R R - DSI bus not in order
R - - - - - - - Power supply error or DSI line too long

1)
This operating state appears in the following situations:
- during a configuration data upload
- After a system first-start
- If the parameter
DECT system state is set to Passive in the AMS Configuration Manager
- 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.)
Green Normal operation (requirement: LED not switched off ):
G - - - - - - - All B channels available
G G G G - - - - 1 to 3 B channels busy
G G G G G G G - > 3 B channels busy
