Specify Tone Parameters for Global Tone Detection (Dialogic Diva Server)
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 returned in the GTD_TONEID variable.
