Tone Profile Features
Understand the configuration fields that define a tone profile.
You use a semicolon to separate the configuration field.
You cannot use spaces in a tone profile pattern.
Tone Field-1 Composition
This field describes frequency components used for tone synthesis and it supports as many as three
different frequencies.
The frequency expression is a string of numeric values with the notation '+' or '-'. The numeric
values are the frequency's decimal values in Hz and amplitude in dBm (maximum 3 dBm). Different
frequencies are separated by a comma.
Example: 350 - 18,440 - 18,550+2
This example means:
● The first frequency at 350 Hz with strength at -18 dBm
● The second frequency at 440 Hz with strength at -18 dBm
● The third frequency at 550 Hz with strength at +2 dBm
Tone Field-2 Composition
This field describes the overall tone playback duration in seconds.
The expression is a numeric value, and supports as many as 3 decimated digits. The numeric value
can negative, zero, positive, or skipped:
● Negative value: tone plays indefinitely
● Zero value: tone playback is skipped
● Positive value: Normal playback duration
● No value: tone plays indefinitely
