Conducting PS Area Check
1.
Call PS(2) from PS(1) to call the registered phone number via PS Registration.
PS(1) sends a tone signal to PS(2), and PS(2) returns the signal back to PS(1).
You can hear a tone when this signal is received.
2.
Set PS(2) close to the IP-CS and move around the service area listening to the tone from PS(1)’s receiver
to confirm voice quality and handover operation.
The CS-ID and signal strength of the IP-CS you are connected to and the target IP-CS for Handover is
displayed on the PS. When the signal strength is sufficiently strong, the CS-ID is displayed in green.
CSnnn-xx yy%
nnn: Current sync CS ID
xx: RSSI level
yy: Error rate
Detected CS IDs and RSSI level are displayed.
If the RSSI level exceeds the threshold, it is displayed with green shading.
Notice
When checking the PS area, ensure that at least one IP-CS is displayed in green on the LCD of the handset
within the service area.
Note
For information about the numbers displayed on this LCD screen, refer to the tables and example image
shown in "5.5.2 Preparing PSs to Test the Radio Signal Strength".
Notes for Conducting PS Area Check
When you conduct PS area checking, please note the following:
•
In order to perform handover for PSs, at least two IP-CSs need to be recognized by the PSs in the service
area.
•
IP-CSs with a signal strength that is sufficiently strong but that are not currently connected are also
displayed in green on the PS's LCD screen.
•
When the PS moves towards another IP-CS, the RSSI level of the currently connected IP-CS changes.
