Tone Profile Features of the OBi Device
The general format for tone profiles follows the following format: [field-1];[field-2];[field-3];...;[field - 6]
Use ";" to separate the configuration fields.
Note that no spaces are allowed to be used in a tone profile pattern.
Field–1 Composition:
This field describes frequency components used for tone synthesis and it supports up to 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 ',' .
Example: 350-18,440-18,550+2
The above example illustrates the 1st frequency at 350 Hz with strength at -18 dBm, the 2nd frequency: 440 Hz with
strength at -18 dBm and the 3rd frequency: 550 Hz with strength at +2 dBm.
Field–2 Composition:
This field describes the overall tone playback duration in seconds.
The expression is a numeric value, and supports up to 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
Example: 30.234
Meaning: tone playback terminates after 30.234 seconds
Field–3 to Field–6 Composition:
Field - 3/4/5/6 share the same definition, and each field describes one single cadence segment. Together 4 fields form a
macro-segment, which will be repeated until tone playback expires.
The expression is a string of numeric values with the special notation '/', '(', ')' and ','.
It has a complete format as below:
