5: The first and third frequencies
6: The second and third frequencies
7: The first and second frequencies if two or more than two frequency components, or the first
frequency if only one frequency component is available.
If no value is provided for
f_0/1/2/3
, it automatically uses the combination of the first one or two
available frequency components.
●
on_0/1/2/3
: the tone active time in seconds
Negative value: Not allowed
No value: infinite tone active time
Others: normal tone active time (as many as 3 decimated digits)
●
off_0/1/2/3
: the tone inactive time in seconds
Negative value: Not allowed
No value: infinite tone inactive time
Others: normal tone inactive time (as many as 3 decimated digits)
Example:
4(1/.3+2.34,3/2+1.5)
This example means:
●
Use the first frequency to generate a tone for 0.3 seconds
●
Follow this tone with 2.34 seconds of silence
●
Use a combination of the first and second frequencies to generate a tone for 2 seconds
●
Follow this tone with 1.5 seconds of silence
●
The cadence operates repeatedly for 4 seconds.
Tone Examples
These examples show the interpretation of a few common tone patterns:
Dial Tone
DIAL, "350-18,440-18"
Dial tone is generated as a mixture of two frequency components:
350 Hz at –18 dBm and 440 Hz at –18 dBm
The expiration time is infinite, and tone active time is infinite.
Busy Tone
BUSY, "480-18,620-18;10;(.5+.5)"
Busy tone is generated as a mixture of two frequency components:
480 Hz at –18 dBm and 620 Hz at –18 dBm
The expiration time is exactly 10 seconds. It has only one cadence segment, which has tone active 0.5
second and tone inactive 0.5 second.
