LTR TRUNKING SYSTEM
LTR Trunking system is a communication system that uses the LTR Trunking protocol and the Trunking system consisting
of Group IDs.
In an LTR Trunking system, the transceiver can communicate via a repeater. The transceiver uses an available channel on
a repeater to communicate.
The following data format is used to transmit and receive the LTR data between the repeater and the transceiver.
Sync
9
The transceiver uses the LTR ID (Group ID) to initiate a call to the target transceiver. Communication will be established if
Encode ID of the transmitting transceiver matches Decode ID of the receiving transceiver.
Encode ID is the LTR ID to be sent when the transceiver transmits.
Decode ID is the LTR ID used to unmute and to allow communications if the received LTR ID matches the LTR ID
preconfigured for the transceiver.
Using the same LTR ID allows a user to communicate within a Group.
