Figure 2-2: Presentation of a DECT base station
If the base station is mounted on a "metal structure" partition, the base station must be 60 to 80
cm from the partition using an extension bracket.
Connections
The maximum cable distance permitted between a base station and the PBX is 800 meters
(principle of the point-to-point S0 bus).
Wiring is carried out using an STP5 cable.
For more information on connecting the base stations according to PBX type, see the
corresponding section on “Deployment principles” and “Implementation of hardware”.
Rules for spacing cables relative to interference sources:
(1) high interference: industrial motors, inverters, rectifiers, transformers, high-voltage power
lines, etc.
Tableau 2 : Rules for spacing cables relative to interference sources
Furthermore, intersections with power cables must be set up at right angles to minimize overlap.
