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.
Using the deployment tool
Assemble the deployment tool as shown in Figure 52: Assembled deployment tool on
page 207, 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 3 to five 5 from the
deployment tool tripod. Establish a link between the basestation and the handset. Keep the
deployment tool basestation in plain view. Ensure no obstructions exist (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. After the
RSSI value changes from 7 to 6 (--80 dBm to --85 dBm) and the last shaded block disappears,
the cell boundary is reached.
After 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:
• Some environments can cause poor tone at a RSSI meter reading of 7 to 10. In this case,
contact Avaya support for assistance.
• The tone stops after the radio link is lost.
For more information about deployment requirements, see Radio synchronization on page
19.
Handset tones interpretation
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 breakup, modulation, mute or click--the handset is beyond cell
boundary edge.
Take the following precautions:
• Do not use the deployment tool on windy days.
• Do not use the deployment tool in bad weather.
• Keep all personnel away from the apparatus.
• Follow all safety requirements.
