6 ANALOG COMMUNICATIONS / 6.1 Using Signaling
DQT Turn-off Code
DQT Turn-off Code is the function to prevent the speaker of the receiving party from emitting the squelch tail noise
by sending the DQT turn-off code after transmission ends on the channel for which DQT Encode is configured.
If a receiving subscriber unit receives the DQT turn-off code, the received audio signal is muted.
The DQT turn-off code is sent for 170 ms and then transmission stops according to the DQT Decode characteristics of
the subscriber unit used in the repeater system.
Waiting to Receive by Multiple Signaling (Multiple Encode/Decode Table)
Multiple Encode/Decode Table is the table configured with the Encode/Decode signaling type that the repeater
waits to receive along with the Primary signaling (the QT tone or DQT code) configured for each channel. If this
function is used, the repeater can wait to receive a maximum of 16 combinations of signaling (a combination of
Primary + 15 combinations of Encode/Decode tones and codes).
A maximum of 15 combinations of QT/DQT can be configured in Multiple Encode/Decode Table. The signaling
configured for each channel is used as Primary for No. 1 signaling in Multiple Encode/Decode Table.
In addition, the signaling table to be used can be changed depending on the status of ports by assigning the function
to change Multiple Encode/Decode Table to AUX Input/Output ports.
(Refer to Available Functions for the AUX Input/Output
To use this function, the following configurations need to be configured using KPG-D7:
・Configuring the Multiple Encode/Decode Table
A maximum of 15 Multiple Encode/Decode Tables can be configured. A maximum of 15 combinations of QT/DQT
are configured for each table. The QT/DQT configured for each channel is used as Primary for No.1 signaling in
Multiple Encode/Decode Table.
・Configuring the Multiple Encode/Decode Table number to be used for each channel
The Multiple Encode/Decode Table number (1 to 15) can be configured for each channel. The repeater can wait to
receive the QT/DQT configured for the channel and the QT/DQT configured in Multiple Encode/Decode Table of
the specified number.
・Configuring the Encode Tone (Multiple)
The QT/DQT to be used to transmit using the PTT (Test PTT and External PTT) control can be configured if the
repeater receives the QT/DQT on the channel where Multiple Encode/Decode Table is configured.
