Synchronization and Deployment Guide
Important parameters
When deploying there are 3 parameters which are equally important:
•
•
•
RSSI-values: Value indicating signal strength
Q-value: Value indicating the signal quality (preferably steady at min 64)
Sound Quality: Measured by walking away from the base station with the handset and
measure where the RSSI value drops below 75 and the Q-value stays constant at 64.
Below is an example of RPN values when pressing *99989* on a handset:
Descriptions of the values above:

The hexadecimal numeral system is used to describe RPN values and time slots.
RPN values range from 00 to FF.
Time slot values range from 0 to B (there are12 time slots)
Third line shows that the actual base station has RPN number 8, signal quality of
connection is 64, signal strength (RSSI) 108, 3BC means third frequency, time slot B, and
that the last handover was a connection handover (C).
A signal quality of 64 is a connection without errors, this number will be reduced by one for
each error (such as reflections or noise). Preferably this value should be steady at
minimum 64.
The value of signal strength range from 110 to 35. Counting down from 110.
