11 LTR TRUNKING SYSTEM
11.6 Other LTR Functions
11.6 Other LTR Functions
The following calls can be used in an LTR Trunking system.
• Transpond
• System Search
• Clear to Talk
• ARQ Mode
Sending Back the Acknowledge (Transpond)
Transpond allows the transceiver to send back an Acknowledgment upon receipt of a call. The transceiver transmits the
Transpond Tone when the Acknowledge signal is transmitted.
Use of this function enables to verify whether the transceiver is within the communication area or not.
The transceiver sends back an Acknowledgment to the dispatcher after the transceiver is called using an LTR ID. The
transceiver starts the transpond when the amount of time configured for Transpond Delay Time elapses. (Refer to
Transpond Delay Time on this
Note
• If the transceiver receives a target ID for Transpond during the scan, the transceiver starts Transpond after the time configured for
Transpond Delay Time elapses. The transceiver resumes scanning after the amount of time configured for Dwell Time elapses. If the
Dropout Delay Time is shorter than the Transpond Delay Time, the transceiver starts the transpond after the amount of time configured
for Dropout Delay Time elapses.
• Transpond will be canceled if the transceiver changes a zone or GID while the Transpond Delay Time is counting down.
• While Transmit Inhibit is activated, the transceiver cannot start to transpond. (Refer to
Receiving ID (Transmit Inhibit) on page
Transpond Delay Time
Transpond Delay Time is the amount of time from when the transceiver receives a Group ID for which Transpond is configured
until the transceiver transmits the Transpond.
If the Dropout Delay Time is shorter than the Transpond Delay Time, the transceiver starts the transpond after the amount
of time configured for Dropout Delay Time elapses. (Refer to
Configuration using KPG-111D/ DN

Automatically Searching for an Available System for Connecting (System Search)
System Search can be used to automatically search for an available system with which to link.
If the transceiver cannot communicate by a user pressing the PTT switch, the transceiver is deemed to be outside of the
system coverage area. In this case, System Search can be used to search for an available system with which to link.
If the transceiver cannot connect to the system while the transceiver is communicating using a Data GID, the transceiver
can search for an available system with which to link using this function. In this case, the base station as a receiving
transceiver must be in a state to receive signals transmitted by the transceiver, for instance by scanning.
There are two ways to initiate System Search: Manual and Auto.
Note
For NX-200S/ NX-300S, the transceiver cannot initiate System Search by the Manual operation.
