Aastra 415/430 as of R3.2
syd-0344/1.6 – R3.2 – 09.2014
Due to the different hardware versions of the radio units, basic systems and inter-
face cards, the power available on the DSI-AD2 bus is not the same in every case:
Power available A:
• Applies to all the system phones of the Aastra 5300 series and the Office series.
• Applies to the SB-4+/SB-8 DECT radio units with hardware version "-1".
• Applies to the SB-4+/SB-8 DECT radio units with hardware version "-2" if they are
not
connected to a basic system with hardware version "-2" or are
not
con-
nected to an EADP4 interface card with hardware version "-3".
