The DECT System
These units support up to 4 simultaneous handset calls each. There are
two versions of the DBS available; a standard DBS and an enhanced
DBS.
A standard DBS uses even timeslots (see page 4).
An enhanced DBS uses odd time slots (see page 4).
Hence, by using a combination of standard and enhanced DBSs, higher
density DECT environments can be deployed. The recommended limit of
DBSs in one area, with a combination of standard and enhanced DBS, is
seven (with ratios of 3:4 or 4:3). If all standard or all enhanced DBSs are
used, then the recommended limit of DBSs in one area is four (seepage
10).
Using standard telephony cable base stations can be placed at up to 2km
from the DECT. Base stations units are designed for wall mounting.
* Older style BDSs (supplied prior to autumn 2001) can only be placed at
up to 1km from the DECT.
Each base station is supplied with a 1.5m line cord for connection to a
Slave Jack Socket (not supplied).
– Size: 100mm wide x 100 high x 40mm deep (inc. wall mounting
bracket).
A Repeater works in conjunction with a Base Station to extend that Base
Station's area of coverage. A directional aerial can be added to increase
the distance from the associated Base Station (up to 1km line of sight).
Each Repeater is programmed to associate with a particular Base Station
using a Repeater Setup program. The Repeater can handle up to two
simultaneous calls. These calls are 'borrowed' from the Base Station.
Hence, each call routed via the Repeater reduces the number of calls that
the Base Station can handle.
The Repeater does not need any wiring connection to the Base Station or
DECT. The Repeater is designed for wall mounting and is supplied with a
plug top PSU fitted with 2 mtrs of cable.
– Size: 100mm wide x 100 high x 40mm deep (inc. wall mounting
bracket).
– Power: Power from a 230V, 50Hz plug top PSU, (9VDC, 300mA).
