NXDN TRUNKING SYSTEM

NXDN is a generic name for a digital communication system protocol utilizing 4-level FSK. Using NXDN, the transceiver can

initiate an Individual Call or Group Call for voice calls, communicate various types of messages, or send and receive GPS data.

Also, connecting a transceiver to an external device (such as a PC) allows communication because the NEXEDGE transceiver

supports serial command communication.

In an NXDN Trunking system, 2 types of channels, control channels and traffic channels, are used (these are referred to

collectively as a system).

A control channel is used for sending various messages to control a system. A control channel is also used for calls, such

as Status Call or Short Data Call.

A traffic channel is used for sending various types of communication information of users.

Via a system, the transceiver can establish communications using NXDN IDs (Unit ID and Group ID), such as an individual

call or group call.

In addition, the transceiver can be operated either in a single system or in multiple systems in an NXDN Trunking system:

the former uses only one system and the latter uses 1 to 8 systems.

Single System

In a single system, the transceiver can use only one system.
