10 ANALOG CONVENTIONAL SYSTEM
10.1 Initiating Voice Communications (Basic Transmission and Reception)
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 Analog Conventional system can participate in an on-going voice call by decoding QT/DQT signaling
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 2-tone, 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 Analog Conventional system.
• Single Scan
• Multi Scan
• List Scan
• Priority Scan
Refer to 19 SCAN on page 436
Transmitting
Pressing the PTT switch starts transmitting. When the signaling (QT/ DQT) is used, the transceiver sends the QT tone or
DQT code. In this case, if the transmitted QT tone or DQT code matches the QT tone or DQT code preconfigured for the
receiving transceiver, the transceivers can communicate.
Restricting the Continuous Transmission Duration (Time-out Timer)
Time-out Timer (TOT) is the function to restrict the duration for the transceiver to continuously transmit.
This function is used to prevent a user from occupying a repeater or frequency which is shared with other users. The
transceiver automatically stops transmitting and releases the channel if it continuously transmits longer than the configured
time.
Time-out Timer can be configured for each zone. Also, timers, such as TOT Pre-alert, TOT Rekey Time, and TOT Reset
Time, relevant to Time-out Timer can be configured.
