Using the Site Survey Kit
Performing the Survey
Position the Survey Base Station in the potential position for a base station
installation. Connect the power supply. If possible also connect an audio source via
either the telephone line or audio jack sockets
1. With a subscribed handset on-hook, dial
*99981*
and press
✓
2. The handset display shows the signal quality
RPN: 01 <Base station number.
Q52: 52 <Speech quality.
RSSI: 64 <Signal strength.
3. Take the handset off-hook as this will ensure more realistic figures
– If you have connected an audio source you will hear it whilst off-hook. Use
this facility to check the audio quality (only one handset can be off-hook and
receive the audio source at any time)
4. Check the boundaries of the Survey Base Stations coverage where
Q52 is
greater than 52
and
RSSI is greater than 64
. Mark this area on the building
plans and check that you have entered all areas that the base station might have
to server
5. Repeat this process with the Survey Base Station in a new location. Check that
the
overlap between coverage areas is at least 10 metres
6. To return the handset to normal operation press and hold
<
until you hear a
short bleep
When the Site Survey is completed, a copy of the Base Station locations and the
plotted coverage must be left on the customers premises. This allows engineers in
the future to review the initial installation and physical layout of the site
