PBX Restrictions
38DHB0002UKFH – Issue 5 (27th October 2003)
PBX Restrictions
–
Collective Ringing Groups:
Including a large number of Compact DECT handsets in a collective
ringing group can cause unpredictable results.
–
Power Fail Circuits:
Compact DECT DAB circuits are not approved for direct connection to
PSTN analogue trunks. This is not a problem when connected via a PBX
except if a PBX directly connects some analogue extensions to analogue
trunks during PBX power failures.
See Power Fail Circuits on page 14.
Environmental requirements
The planned locations for all parts of the system must meet the following
requirements:
– Check that the area is a well ventilated area, having a temperature range
of 0
°
C to +40
°
C and a humidity range of 10% to 90% non-condensing.
– Check there are no flammable materials in the area.
– Check there is no possibility of flooding.
– Check that no other machinery or equipment needs to be moved first.
– Check that it is not an excessively dusty atmosphere.
– Check that the area is unlikely to suffer rapid changes in temperature and
humidity.
– Check for the proximity of strong magnetic fields, sources of radio
frequency and other electrical interference.
– Check there are no corrosive chemicals or gasses.
– Check there is no excessive vibration or potential of excessive vibration,
especially on the cabinet
mounting surface.
Power Supply Requirements
Both the Compact DECT Base Station and Repeater(s) are designed to
operate from a standard 230V (
±
10%), 50Hz single-phase main supply. The
Base Station is rated at 5.4VA and each Repeater is rated at 2.7VA for power
consumption.
The use of a UPS to support the system during mains power failure is highly
recommended. This equipment also provides mains conditioning for the
system. Contact Avaya for details of preferred and tested suppliers and
models.
Cabling & Trunking Requirements
All cables and wires should be run through protective trunking or ducts
wherever possible.
Unless otherwise stated, all devices connect using standard telephone cable
(type CW1308). This can be single or multiple pair cable.
EMC Requirements
The Compact DECT system is EMC approved and carries CE mark approval.
For a particular installation to be EMC compliant, it must meet the following
requirements at all times:
– Only EMC approved equipment must be used.
– You must install all units with their covers in place.
