DTMF Speed
DTMF Speed is the speed to send out the DTMF codes. Transmit speed of the DTMF code can be configured by entering
the number of digits to be sent per second. The transceiver sends the DTMF code at the configured speed.
The transmission speed of the DTMF code can be selected from 6, 8, 10 or 15 digits/ second using KPG-111D/ DN.
Following are durations for Digit Time (transmit time) and Gap Time (muted time) depending on the selected value.

First Digit Delay Time
First Digit Delay Time is the amount of time from when the transceiver starts transmitting until the first digit of the DTMF
code is sent out.
The transceiver transmits an unmodulated signal until the amount of time configured for First Digit Delay Time elapses.
