User's Manual

The signal strength diminishes as the distance between the handset and the basestation
increases. The tone remains unchanged until the handset is out of range of the basestation.
How to use the deployment tool
The deployment tool is assembled as shown in Figure 49: Assembled deployment tool on
page 78, with the extension arm parallel to the floor. Position the basestation antenna upwards.
Place the basestation as close to the wall as possible and at the height recommended for
basestations.
To test the deployment tool, stand in an open area approximately three to five metres away
from the deployment tool on its tripod. Establish a link between the basestation and the
handset. Keep the deployment tool basestation in plain view. Ensure there are no obstructions
(including people).
Walk away from the basestation and observe the deployment handset link display. As the
deployment handset moves away from the basestation, the RSSI value changes. When the
RSSI value changes from 7 to 6 and the last shaded block disappears, the cell boundary has
been reached.
When the cell boundary is reached, stop and listen to the tone. Ensure the tone is clear with
no tone changes, tone breakup, modulation, mutes or clicks.
Do not select a cell edge that has an RSSI reading of less than 6. However, keep the following
in mind.
• There can be environments that cause poor tone at a RSSI meter reading of between 7
and 10. In this case, contact Avaya support team for assistance.
• The tone stops when the radio link is lost.
Interpreting handset tones
The handset tones indicate how close the handset is to the deployment tool basestation.
•
Steady tone – the handset is within the cell boundary, or at the cell boundary edge.
• Tone change, tone break-up, modulation, mute or click – the handset is beyond cell
boundary edge.
