Version: 1.11 Function Reference 6717 LTR TRUNKINGFigure 17-4 Clear to TalkYou can enable/disable the Clear to Talk function usingKPG-89D.! Configuration using KPG-89D• Configuring the Clear to Talk (Refer toFPRG 6.7.5Trunking tab - Clear to Talk.)17.7 ARQ ModeThis function allows a user to finish data communicationsin a Trunking System with a single link operation.When performing data transmission in a LTR TrunkingSystem, the transceiver is normally required to link to arepeater prior to each data transmission. The datatransmission may fail when the system is busy and thereis no available repeater channel. To solve this problem,ARQ Mode allows a user to finish the datacommunication operation in the Trunking system with asingle link.You can use the ARQ function with external Modem andFleetSync.You can enable/disable ARQ Mode using KPG-89DNote:" The transceiver does not transmit when no repeater is availableas the PF Ext. PTT (Voice) port, the PF Ext. PTT (Data) port, orthe PF Data PTT is pressed. When no repeater is available, theSystem Busy terminal becomes active." The System Busy terminal becomes active when no repeater isavailable while the transceiver is in receiving mode, even if thePF Ext. PTT (Voice) port, the PF Ext. PTT (Data) port, or the PFData PTT key is not pressed.! Configuration using KPG-89D• Configuring ARQ Mode (Refer to FPRG 6.7.5Trunking tab - ARQ Mode.)17.7.1 Transceiver Operation WhenUsing the ARQ Function in theExternal ModemWhen the DTC terminal of the external modem is low, thetransceiver starts the ARQ operation. In this case, thetransceiver transmits/receives using the Data GID.During this period, the PF Ext. PTT (Data) port controlscommunication. The transceiver does not transmit theEOT after ending the transmission. When the DTCterminal becomes high, and when PF EXT. PTT (Data)Port becomes high, the EOT is sent and the ARQoperation finishes after the Data CH/GID Dwell Timeexpires.The TOR port becomes low when the Data GID signal isreceived. When the external modem acknowledges thedata receipt, the DTC terminal becomes low and thetransceiver enters ARQ operation. When the PF Ext.PTT (Data) port is activated to transmit the ACK, the datatransmission is made on the specified channel. In thiscase, the transceiver does not transmit the LTR data andthe EOT.17.7.2 Transceiver Operation WhenUsing the ARQ Function withFleetSyncWhen the FleetSync initiates data transmission, thereceiving party starts the ARQ operation. The transceiverdoes 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 isreceived. When the transceiver acknowledges the datareceipt in the FleetSync mode, the transceiver entersARQ Mode. The transceiver does not perform the ACKresponse and the data transmission is made on thespecified channel. In this case, the transceiver does nottransmit the EOT.PTTTransmitReceiveTransmitReceiveDelay Tone Proceed ToneDelay Tone Intercept ToneLinkfailureAttemptingto make aconnectionfor 6 times.** When the Proceed Tone is enabled.
