Default Condition: DTMF Decoder Mute Delay is 0.5 seconds
Examples:
When a DTMF digit is recognized by the controller, it mutes the audio so that
the digit is not re-transmitted. Since some time is required by the controller to
decode the digit, a short burst of tone is re-transmitted. A timer is started for
the purpose of delaying the muting. This allows a string of DTMF digits to be
entered, with all but the first one fully muted. The Select DTMF Decoder Mute
Delay command shown above controls this timer.
• If set to zero, the muting will end when the DTMF digit is released.
• If set to 9, the muting will last 0.9 seconds beyond the release of the DTMF
digit.
Since a voice will occasionally trip the DTMF decoder, a long mute delay may
not be desired.
If a DTMF digit is held down for a continuous period of time, the controller will
stop muting after 10 seconds.
To change the mute delay to 0.3 seconds, for example, enter the following
command:
(PW) 96 3 *
11-8
Form
(PW) 96 x *
