22 FUNCTION PORTS
22.2 D-sub 25-pin Connector (Mobile Only)
DTC
DTC is the port that controls the transceiver to migrate to the Data Zone-channel or GID used for data communications
and then activate ARQ Mode.
The transceiver normally needs to link to a repeater every time to send data in an LTR Trunking system. However, it may take
a longer time to send data, or a data transmission may fail if the system is busy and there is no available channel on the
repeater. ARQ Mode can be used to avoid these problems and unfailingly complete data communications with a single link.
If ARQ Mode is used, the transceiver does not send the EOT until the transceiver finishes data communications once the
transceiver establishes a link to the repeater. The transceiver retains the linked state using the Hung Up Time configured
for the repeater and then send or receive the acknowledgment during the Hung Up Time. With this function, the transceiver
is not required to link to a repeater every time to send data, hence Air Time can effectively be utilized.
The relationship between the channel or GID where the DTC port is activated and the Data Zone-channel or GID is shown
as below.
Current Channel or GID
Conventional Zone-channel (Analog)
Conventional Zone-channel (NXDN)
LTR Trunking Zone-GID
NXDN Trunking Zone-GID
Note
• The data channel is not reverted by Revert CH/GID.
• When the DTC port goes low level during the scan, the transceiver migrates to the Data Zone-channel or GID in the Revert Zone.
• If "Data PTT" is assigned to another port, "DTC" cannot be assigned.
• If "External PTT (Data)" is not assigned to another port, "DTC" cannot be assigned.
Speaker Mute
Speaker Mute is the port that is used to mute the speaker audio output line.
The transceiver mutes the speaker when the Speaker Mute port goes low level. The transceiver unmutes the speaker
when the Speaker Mute port goes high level.
Mic Mute
Mic Mute is the port that is used to mute the microphone modulation line.
The Mic Line (Front Mic and MI2) is muted when the Mic Mute port goes low level. The Mic Line (Front Mic and MI2) is
unmuted when the Mic Mute port goes high level.

Table 22-6 DTC
The transceiver migrates to an analog channel or GID configured for Data Zone-CH/GID
(Analog) in the Conventional Zone.
If no Data Zone-channel or GID (Analog) is configured, the transceiver will migrate to the data
channel (Channel Type = Analog only) configured for the highest channel number in the zone.
The transceiver migrates to an analog channel or GID configured for Data Zone-CH/GID
(Analog) in the Conventional Zone.
If no Data Zone-channel or GID (Analog) is configured, the Key-entry Error Tone sounds from
the transceiver and the transceiver does not respond at all.
The transceiver migrates to an analog channel or GID configured for Data Zone-CH/GID
(Analog) in the LTR Trunking Zone to start transmitting.
If no data Zone-channel or GID (Analog) is configured, the transceiver will migrate to the data
GID configured for the highest GID number in the zone.
The transceiver migrates to an analog channel or GID configured for Data Zone-CH/GID
(Analog) in the NXDN Trunking Zone.
If no Data Zone-channel or GID (Analog) is configured, the Key-entry Error Tone sounds from
the transceiver and the transceiver does not respond at all.
