Specify Tone Parameters for Global Tone Detection
$global_tone chan toneid parmlist
This command applies only to Diva. A $global_tone_parms command is also required.
This command specifies a tone which is recognized during CopiaFacts operations and can be used for application purposes, for example for detecting a specific answering machine type. To determine the parameters to enter, it is easiest to prepare a recording of the tone in a VOX or WAV file use a utility such as Adobe Audition (formerly CoolEdit 2000) to analyze the frequencies.
The parameters on this command are used as follows:
| chan | the channel number or channel group(s) affected, or * for all channels. Up to 32 tones may be defined for each channel. |
| toneid | The tone ID number to identify the tone (a value 1 to 32). CopiaFacts will analyze up to 32 separate tones. |
| parmlist | a list of two white-space-separated values as follows: |
| freq1 | the first or only tone frequency in Hz. |
| fq1dev | the deviation of the above tone in Hz. |
To enable tone detection, assign values to the GTD_CHECK system variable. When a tone is detected, the tone ID is returned in the GTD_TONEID variable.
Hardware Issues: Diva only
Example:
Specify a single tone of between 372Hz and 378Hz :
$global_tone * 1 375 3
