11 LTR TRUNKING SYSTEM
11.2 Using the Optional Signaling (LTR)
11.2 Using the Optional Signaling (LTR)
Optional Signaling is the signaling used to initiate a selective call. DTMF or FleetSync is the Optional Signaling which can
be used in an LTR Trunking system. All signaling types use audible frequencies. (Refer to
DTMF on page 359.)
Configuration using KPG-111D/ DN
Configuring the Optional Signaling (
Conditions to Decode the Optional Signaling
The LTR ID must match in an LTR Trunking system. Therefore, the conditions to decode the Optional Signaling in an LTR
Trunking system is LTR ID Decode only.
Call Alert Beep, the Call Alert display and Transpond are activated if the received Optional Signaling matches the Optional
Signaling preconfigured for the transceiver.
Once Optional Signaling matches, the signaling status remains matched until it is reset.
Unmuting the Speaker (Audio Control (LTR))
Audio Control is the condition which allows the transceiver to unmute the speaker by an LTR ID and Optional Signaling.
The conditions on which the transceiver unmutes the speaker can be configured for each zone.
The transceiver unmutes the speaker and emits received audio if the conditions configured for Audio Control are satisfied.
Conditions to unmute the speaker can be changed by a combination of the LTR ID and the Optional Signaling.
Following are the conditions to unmute the speaker.
Configuration
The transceiver unmutes the speaker if the received LTR ID matches the LTR ID preconfigured for the transceiver.
LTR ID
The conditions for unmuting the speaker do not change even if the transceiver transmits.
Unmuting, Call Alert Beep, the Call Alert display and Transpond are activated if the received LTR ID matches the
LTR ID preconfigured for the transceiver, and if the received Optional Signaling matches the Optional Signaling
LTR ID and preconfigured for the transceiver.
Optional Once Optional Signaling matches, the signaling status remains matched until it is reset. Once Optional Signaling
Signaling matches, the transceiver unmutes if only LTR ID matches.
When the transceiver transmits, the monitor will be activated and matching status of Optional Signaling will be reset.
Therefore, the transceiver unmutes the speaker by LTR ID after the transmission.
