18 DTMF68 Index Contents Confidential FUNC (K)/Ver. 1.0118.2.2 First Digit Delay TimeThe First Digit Delay Time is the delay used for sending aDTMF code when a DTMF code is automatically sent inthe following cases:• Automatically sending the DTMF code using PTT ID,Autodial, Store & Send, BOT, EOT or TelephoneDisconnect (TK-3173 only).• When sending the DTMF code using Keypad AutoPTT.The transceiver transmits unmodulated signals until theFirst Digit Delay Time elapses if the transceiver sends theDTMF code.The First Digit Delay Time can be configured by usingKPG-101D. Configuration using KPG-101D• Configuring the First Digit Delay Time (Refer toFPRG 6.10.1 Encode Tab - First Digit Delay Time.)18.2.3 First Digit Delay Time with QTThe First Digit Delay Time with QT is the durationbetween when the transceiver starts transmitting andwhen it starts transmitting the first digit of the DTMF codeif the transceiver automatically sends the DTMF code ona channel configured with QT/DQT with PTT ID, Autodial,Store & Send, Beginning of Transmit, End of Transmit orKeypad Auto PTT. The transceiver transmitsunmodulated signals until the First Digit Delay Timeelapses.The First Digit Delay Time with QT can be configured byusing KPG-101D. (Refer to FPRG 6.10.1 Encode Tab -First Digit Delay Time with QT.)18.2.4 First Digit TimeThe First Digit Time is used to adjust the time length ofthe first DTMF digit when a DTMF code is automaticallysent.The duration of the transmitted first digit of DTMF is thesum of the transmission time configured for DTMF Speedand the First Digit Time.By extending the transmission time of the first digit of thesent code, the DTMF code can be reliably received by thetransceiver at the receiving end even if its Power Saver isenabled or the transceiver is scanning.The First Digit Time can be configured by usingKPG-101D. Configuration using KPG-101D• Configuring the First Digit Time (Refer to FPRG6.10.1 Encode Tab - First Digit Time.)18.2.5 * and # Digit TimeThe * and # Digit Time is the extended transmission timefor a * tone or # tone when a DTMF code is automaticallysent.The duration of the transmitted * tone and # tone is thesum of the transmission time configured for DTMF Speedand the * and # Digit Time.If the first digit of the DTMF code is the * tone or # tone,the transceiver compares the extension time to send thefirst digit configured for the First Digit Time with the * and# Digit Time and uses the longer extension time to sendthe first digit.The * and # Digit Time can be configured by using KPG-101D. Configuration using KPG-101D• Configuring the * and # Digit Time (Refer to FPRG6.10.1 Encode Tab - * and # Digit Time.)18.2.6 DTMF Hold TimeThe DTMF Hold Time is the duration from when thekeypad is disabled to when the transceiver returns toreceive mode if the transceiver sends a DTMF code byusing Keypad Auto PTT or Manual Dialing.The transceiver at the receiving end treats anuninterrupted DTMF signal that it receives as one codesequence. The DTMF Hold Time is therefore used tomaintain an uninterrupted transmission to send a seriesof DTMF codes.The DTMF Hold Time can be configured by using KPG-101D. Configuration using KPG-101D• Configuring the DTMF Hold Time (Refer to FPRG6.10.1 Encode Tab - DTMF Hold Time.)18.2.7 D Code AssignmentD Code Assignment can be used to configure whether theD code is used for D code of DTMF or a dialing pause.D Code Assignment can be configured by usingKPG-101D. Configuration using KPG-101D• Configuring the D Code Assignment (Refer toFPRG 6.10.1 Encode Tab - D Code Assignment.)
