Using the Signaling
NAC is the signaling to be used for facilitating communication within a group if the same channel is shared by several groups.
Sharing the Same Channel (Frequency) by Several Groups (NAC)
NAC (Network Access Code) is a digital signaling type having the same function as analog QT tone or DQT code. This
signaling is used when the transceiver transmits or receives on a P25 channel.
The transceiver mutes calls that the transceiver does not wait for if a NAC is configured for each channel. Therefore, a user
can communicate in a group without listening to conversations from other groups.
The following are transmission and reception behaviors of NAC.
Table 1-3 NAC Transmission/ Reception Behaviors
Reception
The transceiver behavior varies depending on the configuration in
Squelch Type
(NAC or
Selective Call).
NAC:
If the received NAC matches the NAC preconfigured for the transceiver, the transceiver emits
the received audio from the speaker.
Selective Call:
If the received NAC matches the NAC preconfigured for the transceiver and the received
Talkgroup ID or Individual ID matches the Talkgroup ID or Individual ID preconfigured for the
transceiver, the transceiver emits the received audio from the speaker.
Transmission
The transceiver sends the preconfigured NAC when transmitting. Pressing the
PTT
switch causes
the transceiver to send the NAC.
