click on its Value and enter the new information in the text box. Then press
another field to save your change. The definitions of the parameters are:
•
DTMF Digit Detect On: Determines the minimum duration of DTMF tones that can be
recognized by Voice Processing during Play Mode (for example, when a prompt or
message is playing). Valid settings for this parameter are 32, 48, 64, 80, or 96 millisec-
onds. The default is 48 milliseconds.
•
DTMF Digit Detect Off: Determines the minimum silence allowed between DTMF
tones that can be recognized by Voice Processing during Play Mode. Valid settings for
this parameter are 32 or 48 milliseconds. The default is 48 milliseconds.
•
DTMF Digit Delay On: Determines the minimum duration of DTMF tones that can be
recognized by Voice Processing during Idle Mode (for example, when Voice Processing
is waiting for input). Valid settings for this parameter are 32, 48, 64, 80, or 96 millisec-
onds. The default is 32 milliseconds.
•
DTMF Digit Delay Off: Determines the minimum silence allowed between DTMF
tones that can be recognized by Voice Processing during Idle Mode. Valid settings for
this parameter are 32 or 48 milliseconds. The default is 48 milliseconds.
•
DTMF Digit Low To High Twist (Play and Idle): Reflects the difference between the
DTMF digit high frequency and low frequency energy (high minus low). To allow the
Voice Processor to detect a digit that consists of frequencies, the high frequency energy
cannot be stronger than the low frequency energy by more than the setting of this
parameter. In Play Mode the default for this parameter is 9.2dB. In Idle Mode the
default is 8.2dB. Valid settings for this parameter are: No Limit, 6.7dB, 8.2dB, 9.2dB,
10.7dB, 12.7dB, 15.2dB, or 18.2dB.
•
DTMF Digit High To Low Twist (Play and Idle): Reflects the difference between the
DTMF digit low frequency and high frequency energy (low minus high). To allow the
Voice Processor to detect a digit that consists of frequencies, the low frequency energy
cannot be stronger than the high frequency by more than the setting of this parameter.
In Play Mode the default for this parameter is 8.2dB. In Idle Mode the default is 5.2dB.
Valid settings for this parameter are: No Limit, 4.2dB, 5.2dB, 6.7dB, 8.2dB, 10.2dB,
13.2dB, or 18.2dB.
•
DTMF Digit In To In Ratio (Play and Idle): Indicates a digit's energy minus the next
digit's energy. In order for the Voice Processor to detect a digit that consists of frequen-
cies, a digit's energy must be stronger than the next digit's energy by the amount of this
parameter setting. The default setting for Play Mode is 2.0dB. The default setting for
Idle Mode is 8.0dB. Valid settings for this parameter are 1.0dB, 2.0dB, 3.0dB, 4.0dB,
6.0dB, 8.0dB, 9.0dB or 10.0dB.
•
DTMF Digit In To Out Ratio (Play and Idle): Indicates a digit's energy minus the
noise energy. In order for the Voice Processor to detect a digit that consists of frequen-
cies, the digit's energy must be stronger than the noise energy by at least the amount of
this parameter setting. The default setting in Play Mode is 1.0dB. In Idle Mode, the
default is 4.0dB. Valid settings for this parameter are 0.5dB, 1.0dB, 2.0dB, 3.0dB,
3.5dB, 4.0dB, 4.5dB, or 5.0dB.
