Firmware System Aastra 400 DECT

DECT radio units SB-4+, SB-8 and SB-8ANT
The Flash memory on the radio units contains an area that cannot be modified. It is
used for starting the radio unit and receiving the firmware for the radio unit.
The actual firmware for the radio unit is contained in the communication server's
system software. The loaded firmware is tested when the radio unit starts up. If the
loaded firmware is not identical to the version in the system software, the firmware
will be downloaded from the communication server on to the radio unit and stored
in the Flash memory of the radio unit.
Cordless DECT phones of the Aastra 600c/d family
The firmware for the Aastra 600c/d cordless phones, is updated via radio (Air-
Download). The update can be enabled or disabled individually for each cordless
phone using the menu System - Download server on the cordless phones. If the
cordless phone is logged on to several systems, this menu defines which system
the firmware update is relevant to.
There is only one firmware for the cordless Aastra 600c/d series phones. It is in-
cluded in the communication server's software package and stored in the file sys-
tem of the communication server.
DECT cordless phones Office 135 and Office 160
The firmware for the Office 135 and Office 160 cordless phones, is updated via ra-
dio (Air-Download). This requires the cordless phone to be logged on to system A.
The memory in the cordless phones is a Flash memory. The Flash memory contains
an area that cannot be modified. This area contains the cordless phone's boot soft-
ware.
The firmware for the cordless phones is contained in the communication server
software package. The loaded firmware is tested when the cordless phone starts
up. If the loaded firmware is not identical to the version in the system software, the
system will initiate an Air-Download. The firmware is loaded from the communica-
tion server onto the cordless phones via radio and stored in the Flash memory.
To be able to run an Air-Download, you need to ensure that the cordless phone
contains a functional firmware.
The cordless phone remains fully functional during an Air-Download. The new
loaded firmware is activated only once the Air-Download has been successfully
completed. A restart is carried out on the cordless phone.
