Operation and Maintenance
DECT cordless phones Office 135 and Office 160
The software for the Office 135 and Office 160 cordless phones, is updated via radio
(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 software for the cordless phones is contained in the communication server
software package. The loaded software is tested when the cordless phone starts
up. If the loaded software is not identical to the version in the system software, the
system will initiate an Air-Download. The software 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 software.
The cordless phone remains fully functional during an Air-Download. The new
loaded software is activated only once the Air-Download has been successfully
completed. A restart is carried out on the cordless phone.
