7-2
General
APCO Project-25 (P25) is designed for public safety
digital radio, and allows you to make a call to a
specific station (Individual call) or to a particular group
(Talkgroup call) in the Conventional mode.
Other P25 transceivers on the channel will not listen in
on a call that does not match their Individual/Talkgroup
group ID or Network Access Code (NAC).
Moreover, the following functions and calls are
available: Call Alert function, Radio Inhibit/Uninhibit
function, Remote Monitor function, Radio Check
function, Status Message, Short Message, Status
Query, Phone Call and Emergency Call function.
NAC matching is not necessary for the above
functions and calls.
Each transceiver has a unique ID, and it allows
to be substituted with an alphanumeric name, if
programmed.
You can use this ID (or name) to select a target station
to call, and the ID (or name) of the target station is
displayed after receiving a call.
