Rules and guidelines
The following rules and guidelines apply to basestation installation.
• For DC-powered systems, an input voltage of at least –48 volts is required for maximum
basestation line length.
• One hundred ohms is the maximum line length for a C4610 high traf
fic basestation. If the
line measurement approaches 100 ohms, use an external power supply.
• If the exact location is not accessible, mount the basestation as close as possible to the
location in the site survey.
• Mount the basestation in a vertical position, not horizontally, on a ceiling.
• Lead the basestation cable directly away from the basestation. Surplus cable can cause
basestation malfunctions.
• Place the basestation where it is unlikely to be damaged. For example, a basestation in
a warehouse must be placed where it cannot be damaged by a forklift truck.
• Surrounding objects must not affect the basestation. For example, a basestation in a car
park must be placed higher than any vehicle parked next to it.
• The minimum distance between two basestations must be greater than two metres.
• Do not mount basestations on large concrete or stone columns, air ducts or large metal
objects.
• The external basestation is powered from the line connection and does not require a
mains connection.
• Use the external housing kit to mount any basestation out-of-doors.
• Use the external housing kit for any basestation subject to conductive pollution or dust
that can become conductive due to condensation.
Compatibility
The C4600, C4610, and C4610E basestations are compatible with all software releases for
DECT
, Meridian 1, CS 1000E and CS 1000M systems. The basestations are backward
compatible.
C4610E and external antenna
The C4610E 12-channel basestation has an adaptor to support an external antenna.
The
external antenna increases the operating distance between the basestation and the DECT
handset. Avaya recommends the use of a Huber & Suhner dual-planar directional antenna.
Directional antennas are suitable for use in places such as large halls, outside parking lots,
