Ascotel® DECT radio unit
The Flash memory on the Ascotel® DECT radio unit contains an area that cannot be
modified. It is used for starting the radio unit and receiving the software for the ra-
dio unit.
The actual software for the radio unit is contained in the PBX's system software. The
loaded software is tested when the radio unit starts up. If the loaded software is not
identical to the version in the system software, the software will be downloaded
from the PBX on to the Ascotel® DECT radio unit and stored in the Flash memory of
the Ascotel® DECT radio unit.
Office 135 and Office 160 DECT handsets
The software for the Office 135 and Office 160 DECT handsets, is updated via radio
(AIR download). This requires the handset to be logged on to system A.
The memory in the handsets is a Flash memory. The Flash memory contains an area
that cannot be modified. This area contains the handset's boot software.
The software for the handsets is contained in the PBX software package. The
loaded software is tested when the handset starts up. If the loaded software is not
identical to the version in the system software, the PBX will initiate an AIR down-
load. The software is loaded from the PBX onto the handsets via radio and stored in
the Flash memory.
To be able to run an AIR download, you need to ensure that the handset contains a
functional software.
