11 LTR TRUNKING SYSTEM
11.1 Using the LTR ID for Basic Communications
Data Delay Time
Data Delay Time is the delay time from when the transceiver starts transmitting until the transceiver starts sending the LTR
data. This function can be used when the transceiver is having a hard time linking with the repeater.
Configuration using KPG-111D/ DN

Scan Weight
Scan Weight is the length of time to decode the LTR ID sent from a repeater while the transceiver is scanning.
The transceiver receives its own LTR ID from a repeater, and then the transceiver will unmute or proceed to Trunkout.
Frequent use of the same GID as own Home Repeater number indicates that those who have the same Home Repeater
number are doing Trunkout. Therefore, it may take a long time to receive the LTR ID addressed to own transceiver.
Therefore, Scan Weight must be configured longer so as not to miss LTR Data during the scan.
1 unit of weight is approximately 500 ms.
Note
If the duration configured for Scan Weight is too long, the speed of System Scan of the transceiver will slow down. The appropriate
value for Scan Weight must be determined by checking the congestion of the system and noticing how frequently GIDs having the
same home number are used.
Configuration using KPG-111D/ DN

Receiving
Transceivers can communicate only if the received LTR ID matches the LTR ID preconfigured for the receiving transceiver.
Received audio sounds from the speaker while the received LTR ID matches the LTR ID preconfigured for the transceiver.
Participating in an On-going Voice Call Midway Through the Call (Late Entry)
Late Entry is the function to participate in on-going voice calls even if the transceiver receives a voice call midway through
the call.
The transceiver in an LTR Conventional system can participate in an on-going voice call by decoding the LTR ID always
sent along with audio data, even if the transceiver receives a voice call midway through the call. However, the transceiver
cannot participate in an on-going call from a group call or individual call using Optional Signaling (such as DTMF and
Fleetsync) even if the transceiver receives a signal, since signaling is sent one-time when starting transmission.
Searching Whether the Transceiver Receives a Call (Scan)
Using the Scan function, the transceiver can check each channel in turn whether the channel has a signal. If a channel has
a signal, the transceiver receives the signal on the channel.
The following scan functions can be used in an LTR Trunking system.
• Single Scan
• Multi Scan
• List Scan
• Group Scan
