Introduction
The Compact DECT Repeater allows you to extend the range of coverage of
a Compact DECT Base Station (CDBS) without requiring more wiring to the
system. The only physical connection required for each Repeater is a mains
supply. Two versions of the Repeater are available; a standard Repeater and
a Repeater that can have an optional directional aerial fitted (see below).
Up to six Repeaters can be added to an existing CDBS as shown below.

Repeater 3
Repeater 1
Repeater 2
Repeater 4
Repeater 5
Repeater 6
Note:
When programming for Repeater Jumps, you must start with
Repeater 4 to CDBS, followed by Repeater 5 to 4 and finally
Repeater 6 to 5.
E.g. Repeater 4 acts as a base station for Repeater 5, which in
turn acts as a base station to Repeater 6.
The range at which a Repeater can work will typically be between 50 and
150m within a building. Each Repeater works in conjunction with an existing
parent DECT Base Station. These calls are 'borrowed' from the CDBS.
Hence, each call using a Repeater reduces by one the capacity of its parent
CDBS (capacity of 6 calls). A Repeater jump link can only handle two
simultaneous call at any one time.
The use of a directional aerial allows the Repeater to be placed up to 1000m
from its parent base station (subject to intervening structures) as follows.
