58 Operating in P25 trunking mode
About P25 trunking
Your radio may be able to operate on a P25 trunking
system as well as a conventional repeater-based system.
On a conventional system, radio users compete for
access to individual channels, and one channel can be
overloaded with traffic while others are often unused.
The trunking system allows several channels to be
automatically shared by a number of radio users. These
traffic channels are pooled and allocated, as required,
for the duration of a call. As calls are completed, the
traffic channels are returned to the pool, to be used for
other calls. This system means reduced waiting times to
make calls.
Checking that the system is available
When you first switch to a talkgroup configured for P25
trunking, the radio attempts to access the network and
register on a control channel.
If registration is successful, the trunking system available
symbol
appears in the display.
Registration is unsuccessful
If registration is not successful, does not appear, and
the display shows No service .
The radio sounds five beeps, followed by a repeating
double beep. The double beep continues until
registration is successful.
