8 NXDN CONVENTIONAL SYSTEM
8.1 Initiating Voice Communications (Basic Transmission and Reception)
Over-the-Air Alias
Over-the-Air Alias allows the receiving transceiver having the display function to display the ID Name of the transmitting
transceiver when receiving a call even if the ID Name of the transmitting transceiver is not configured for the receiving
transceiver.
Using this function, Unit ID Name of the added unit does not need to be configured such as when a unit is added to the
system in service.
The transmitting transceiver sends Unit ID Name when making voice calls. If the receiving transceiver having the display
function receives a call such as an Individual Call, the Unit ID Name stored in the reception frame will appear on the main
display.
Note
• The received Unit ID Name appears after displaying differently from the received Unit ID Name in the following cases.
• The Unit ID of the transmitting transceiver is not configured in the Unit ID List.
• The Unit ID of the transmitting transceiver is not stored as Caller ID.
• The received Unit ID Name is different from the ID configured in the Unit ID List or the ID Name stored in the transceiver.
• NX-240/ 240V/ 340/ 340U/ 740H/ 740HV/ 840H/ 840HU does not support the function to display the ID Name.
Configuration using KPG-169D/ KPG-170D/ KPG-175D

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.
Refer to
16 SCAN on page 172
Transmitting
Pressing the PTT switch starts transmitting. When a signaling (RAN) is used, the transceiver sends the RAN code. In this
case, if the transmitted RAN code matches the RAN 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. A Warning Tone A sounds from the transceiver at this time.
Timers, such as TOT Pre-alert, TOT Rekey Time, and TOT Reset Time, relevant to Time-out Timer can be configured.
