Spectralink IP-DECT Server 400/6500 and DECT Server 2500/8000 Synchronization and Deployment Guide
Important Parameters
When deploying, there are 3 parameters which are equally important:
RSSI values: Value indicating signal strength
l
Q value: Value indicating the signal quality (preferably steady at 64)
l
Sound Quality: Measured by walking away from the base station with the handset and meas-
l
ure where the RSSI value drops below 75 and the Q value stays constant at 64.
Example and Description of Values (RPN, RSSI, Quality) (Only relevant to Spectralink
Handset 7202/7212/7522/7532/7622/7642/7722/7742)
Descriptions of the values above:
RPN (Radio Part Number) values range from 0 - 255.
l
RSSI (Received Signal Strength Indicator) values range from 35 - 124. Counting down from
l
124.
QV (Quality) values range from 0-64.
l
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 64.
FTS ( Frequency, Timeslot, State)
l
Time slot values range from 0 to B (there are 12 time slots)
o
State: E = Economy mode active. B, C indicates if last handover was a connection han-
o
dover or a bearer handover.
Note:
To only see handover type, disable Economy mode in the handset menu (Set-
tings > Advanced > Economy mode).
First line shows that the actual base station has RPN number 14, signal strength (RSSI) 124,
l
signal quality of connection is 64, 99C means ninth frequency, time slot 9, and that the last han-
dover was a connection handover (C).
Last four lines are candidates for connection handover (if any). Only the RSSI value and the
l
RPN value is shown.
