17.7 ARQ Mode

This function allows a user to finish data communications
in a Trunking System with a single link operation.
When performing data transmission in a LTR Trunking
System, the transceiver is normally required to link to a
repeater prior to each data transmission. The data
transmission may fail when the system is busy and there
is no available repeater channel. To solve this problem,
ARQ Mode allows a user to finish the data
communication operation in the Trunking system with a
single link.
You can use the ARQ function with external Modem and
FleetSync.
You can enable/disable ARQ Mode using KPG-89D
Note:
" The transceiver does not transmit when no repeater is available
as the PF Ext. PTT (Voice) port, the PF Ext. PTT (Data) port, or
the PF Data PTT is pressed. When no repeater is available, the
System Busy terminal becomes active.
" The System Busy terminal becomes active when no repeater is
available while the transceiver is in receiving mode, even if the
PF Ext. PTT (Voice) port, the PF Ext. PTT (Data) port, or the PF
Data PTT key is not pressed.

When the DTC terminal of the external modem is low, the
for 6 times.
transceiver starts the ARQ operation. In this case, the
transceiver transmits/receives using the Data GID.
Link
During this period, the PF Ext. PTT (Data) port controls
failure
communication. The transceiver does not transmit the
EOT after ending the transmission. When the DTC
terminal becomes high, and when PF EXT. PTT (Data)
Port becomes high, the EOT is sent and the ARQ
operation finishes after the Data CH/GID Dwell Time
expires.
The TOR port becomes low when the Data GID signal is
received. When the external modem acknowledges the
data receipt, the DTC terminal becomes low and the
transceiver enters ARQ operation. When the PF Ext.
PTT (Data) port is activated to transmit the ACK, the data
transmission is made on the specified channel. In this
case, the transceiver does not transmit the LTR data and
the EOT.
17.7.2 Transceiver Operation When
When the FleetSync initiates data transmission, the
receiving party starts the ARQ operation. The transceiver
does not transmit the EOT after ending the transmission.
When the FleetSync Data communication is completed,
the EOT is sent and ARQ operation ends.
The TOR port becomes low when the Data GID signal is
received. When the transceiver acknowledges the data
receipt in the FleetSync mode, the transceiver enters
ARQ Mode. The transceiver does not perform the ACK
response and the data transmission is made on the
specified channel. In this case, the transceiver does not
transmit the EOT.
