NXDN™ OPERATION

NXDN™ system operation
NXDN is a new “Common Air Interface” (CAI), the
name for over-the-air methods by which transceivers
and repeaters communicate. NXDN defines the next-
generation digital transceiver.
The NXDN system has two operating modes,
Conventional and Trunking.
In an NXDN Conventional system, you manually
search for an empty channel.
In an NXDN Trunking system, the transceiver
automatically searches for an empty channel, and
sends the information to the transceivers. In addition,
a Control Channel repeater is required.
If you use an NXDN transceiver, you can transmit
or receive an Individual Call, Group Call, Status
Message, Short Message, Call Alert call, and so on.

NXDN Conventional operation
The NXDN Conventional system enables efficient
Conventional operation in the digital mode.

To select the Conventional zone, see page 3-3.
z
Multi-site Conventional operation
The Multi-site Conventional system can support up to
16 sites (each site has one repeater) through an IP
network, and enables efficient Conventional operation
in the digital mode.
L
To select the Multi-site Conventional zone, see page 3-3.
z
Single-site Trunking operation
The Single-site Trunking system enables further
effective channel management by sharing a minimum
number of channels with a large number of users.
L
To select the Single-site Trunk zone, see page 3-3.
z
Multi-site Trunking operation
The Multi-site Trunking system can support up to 48
trunked sites through an IP network. This enables
the users to communicate with stations through the
interlinked trunked site.
Each site can have up to 30 repeaters.
L
To select the Multi-site Trunk zone, see page 3-3.
NOTE:
During the Single-site or Multi-site Trunking
operation, you can receive and transmit digital calls
in the same way as in the Conventional mode.
