5.13 Project 25 Mode Features
The following features are unique to conventional P25 channels.
5.13.1 Digital Unit ID
Each radio that operates on Project 25 (digital) channels is programmed with an eight-digit
unit ID. This ID is unique for each radio and can be any number from 1-16,777,215. When
power is turned on with a Project 25 channel selected, this ID is briefly displayed.

5.13.2 Talkgroup ID
Each Project 25 channel is programmed with a talkgroup ID that determines which group
of radios will receive the call. A call is received on a channel if a selected or scanned
channel is programmed with that ID and the correct NAC is detected (see following).
Talkgroup IDs can be any number from 0-65,535. Talkgroup ID detect can be disabled by
the Normal/Selective squelch function described in Section 5.4.1 or the monitor mode
described in Section 5.2

5.13.3 Network Access Code
Project 25 conventional channels also use a NAC (Network Access Code) to control
which calls are received on a channel. The NAC can be 0-4095, and each transmit and
receive channel can be programmed for a different code. Other operation, such as
monitoring before transmitting, is similar to that of analog channels. NAC (and talkgroup
ID) detect can be disabled by the monitor mode described in Section 5.2.
