10. IP‐DECT SERVER 400 & IP‐DECT BASE STATION
The IP‐DECT Server 400 controls the IP‐DECT Base Station(s) and manages the IP interface to an optional
IP‐PBX. The communication protocol between the IP‐DECT Server 400 and the IP‐PBX is SIP. The IP‐DECT
Server 400 uses the wireless band ETSI (1880‐1900 MHz), referred to as 1G8.
The IP‐DECT Server 400 can be deployed as either a single‐cell or multi‐cell solution. The single‐cell option is
easy to deploy for a small scheme, where there is the need for more users or coverage of a larger area then
the multi‐cell solution can be used with up to 3 additional IP‐DECT Base Stations.
The IP‐DECT Base Station has 12 simultaneous traffic channels (32Kbits/s), this controls the traffic in the air
and works as the link between the DECT handsets and the IP‐DECT 400 Server.
IP‐DECT 400 Servers and Base Stations are housed in the same ABS enclosure; always check the Model No.
