15 LTR TRUNKING
15.6 Clear to Talk
Clear to Talk can be used to emit the Delay Tone when
the transceiver accesses the repeater more than 3 times
after the PTT switch is pressed.
The transceiver emits the Delay Tone if the Clear to Talk
checkbox is not checked. If the transceiver emits the
Delay Tone, a user will notice that it is difficult to access
to the repeater.
Note: The transceiver emits the PTT Proceed Tone if Clear to Talk
is enabled in the TK-280/ TK-780. The PTT Proceed Tone
can be separately configured for the TK-3173.

15.7 ARQ Mode
This function allows a user to finish data communications
in LTR Trunked Radio System with a single link
operation.
When sending data in LTR Trunked Radio System, the
transceiver is normally required to link to a repeater every
time to send data. Therefore, data transmission may fail
when the system is busy and there is no available
channel on the repeater. To solve this problem, ARQ
Mode allows a user to finish data communications with a
single link.
ARQ can be used in FleetSync.
ARQ Mode can be configured to be enabled or disabled
by using KPG-101D.

15.7.1 Transceiver Operation When
If the transceiver starts sending FleetSync data, the
transceiver enters ARQ mode. In this case, the
transceiver does not send the EOT even if the transceiver
finishes sending data. The transceiver sends the EOT to
terminate ARQ operation when the transceiver finishes
sending all FleetSync data.
The TOR port is low if the receiving end receives the Data
GID signal. When the transceiver acknowledges that it
received FleetSync data, the transceiver enters ARQ
operation. The transceiver sends data with the channel
specified by the repeater without sending the ACK
message. In this case, the transceiver sends LTR Data
only and does not send the EOT. The transceiver sends
TOR from the AUX 2 Output port.
