Kenwood NEXEDGE NX-248 Instruction Manual page 25

If BCL Override has been programmed, you can transmit over
the current signal:
1 Press and hold the PTT switch.
• If the channel is already in use, a warning tone will sound.
2 Quickly release and then press the PTT switch again.
3 Speak into the transceiver as you would during a normal call.
PTT ID
PTT ID is the transceiver unique ID code which is sent each
time the PTT switch is pressed and/or released.
Note:
◆ PTT ID can be made only in analog operation.
SIGNALING
■ QT/ DQT
The Encoder/Decoder function uses QT/ DQT to segregate
talk groups, so users only hear calls from their own group.
■ Radio Access Number (RAN)
RAN is a signaling system designed for digital radio
communications. When a channel is set up with a RAN,
squelch will only open when a call containing a matching
RAN is received. If a call containing a different RAN is
made on the channel you are using, you will not hear the
call. This allows you to ignore (not hear) calls from other
parties who are using the same channel.
■ NXDN ID
NXDN ID is an optional signaling system available only for
digital communications.
■ DTMF
A DTMF PTT ID is included for dispatch operations or
simple remote control applications. The DTMF decode
capabilities include Selective Call ID, Transpond with ID,
and "Wild Card" Group Calling.
