NXDN OPERATION <COMMON>
6-2
NXDN system operation
NXDN is a “Common Air Interface” (CAI), the name for
over-the-air methods by which transceivers and repeat-
ers communicate. NXDN defines the next-generation
digital protocol.
The NXDN system has two operating modes, conven-
tional and trunking.
In an NXDN conventional system, you should manually
search for a clear channel.
In an NXDN trunking system, the repeater automati-
cally searches for a clear channel, and sends the infor-
mation to the transceivers.
In addition, Type-C requires a Control Channel repeat-
er.
If you use an NXDN transceiver, you can transmit and
receive Individual Calls, Group Calls, Status Messages,
Short Messages, and so on.
