Specify Tone Parameters for Global Tone Detection (Dialogic Diva Server)
$global_tone line tonetype parmlist
This command specifies a single tone range within which tones are recognized during CopiaFacts operations and can be used for application purposes, for example for detecting a specific answering machine type.
The parameters on this command are used as follows:
| line | the line number or line group(s) affected, or * for all lines. Only one tone range may be defined for each line. |
| tonetype | a value of 1 for single-tone detection is currently the only supported value. |
| parmlist | a list of five white-space-separated values as follows: |
| minduration | the minimum duration of the tone in milliseconds |
| minsnr | the minimum signal to noise ratio, expressed in decibels in the range 127db to -127db. |
| minlevel | the minimum level of the detected signal, expressed in decibels in the range 127db to -127db. |
| maxAM | the maximum allowed variation of the signal level, expressed in decibels in the range 0db to -255db. |
| maxFM | the maximum allowed variation of the signal frequency during tone detection, expressed in Hz. Note that this value limits the variation in frequency which is to be considered as a single tone. This differs from the $global_tone fq1dev parameter which specifies the variation in the reported value which will be accepted as indicating the specified tone ID has been detected. |
To define tone IDs for specific frequencies, use $global_tone commands. To enable and disable global tone detection, assign a value to the GTD_CHECK system variable. When a tone is detected, the tone ID is is returned in the GTD_TONEID variable.

Example:
$global_tone_parms DIVA 1 100 18 -36 1 5
$global_tone DIVA 1 340 10 ; ID1 is 340Hz ±10
$global_tone DIVA 2 400 10 ; ID2 is 400Hz ±10
