9 ANALOG CONVENTIONAL SYSTEM
9.2 Using the Signaling
Using the Optional Signaling (Analog)
Optional Signaling is the signaling used to initiate a selective call. DTMF, 2-tone, or FleetSync is the Optional Signaling
which can be used in an Analog Conventional system. All signaling types use audible frequencies. (Refer to
tone to Initiate a Selective Call on page
The transceiver behaves as follows according to the configuration for Optional Signaling Decode Condition:
"QT/DQT" is configured for Optional Signaling Decode Condition:
If the received QT tone or DQT code matches the QT tone or DQT code preconfigured for the transceiver and the
received Optional Signaling matches the Optional Signaling preconfigured for the transceiver, the transceiver emits the
Alert Tone or starts Transpond.
"Carrier" is configured for Optional Signaling Decode Condition:
If the transceiver receives a carrier and the received Optional Signaling matches the Optional Signaling preconfigured
for the transceiver, the transceiver emits the Alert Tone or starts Transpond. In this case, the received QT tone or DQT
code does not need to match the QT tone or DQT code preconfigured for the transceiver.

Unmuting the Speaker (Audio Control (Analog))
Audio Control is the condition which allows the transceiver to unmute the speaker. The conditions on which the transceiver
unmutes the speaker can be configured for each channel.
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 QT tone or DQT code and Optional Signaling.
Conditions to unmute the speaker can also be changed by changing a combination of carrier and Optional Signaling.
The conditions to unmute the speaker when the transceiver uses a QT tone or a DQT code are as follows:

Table 9-4 Audio Control (Analog) (QT/DQT)
If the transceiver receives a carrier and the received QT tone or DQT code matches the QT tone or
DQT code preconfigured for the channel, the transceiver unmutes the speaker.
If the transceiver receives a carrier and all the following conditions are satisfied, the transceiver
unmutes the speaker:
The received QT tone or DQT code matches the QT tone or DQT code preconfigured for the
channel.
The received Optional Signaling matches the Optional Signaling preconfigured for the channel.
If the transceiver receives a carrier and the received QT tone or DQT code matches the QT tone or
DQT code preconfigured for the channel, the transceiver unmutes the speaker.
Or, if the transceiver receives a carrier and the received Optional Signaling matches the Optional
Signaling preconfigured for the channel, the transceiver unmutes the speaker.
