9.2.1
Site Trunking
Site Trunking is only available with Capacity Max system. A site must be able to communicate with the
Trunk Controller to be considered as System Trunking.
If the site cannot communicate with the Trunk Controller in the system, a radio enters Site Trunking
mode. While in Site Trunking, the radio provides a periodic audible and visual indication to the user to
inform the user of their limited functionality.
When a radio is in Site Trunking, the radio displays Site Trunking and a repetitive tone sounds.
The radios in Site Trunking are still able to make group and individual voice calls as well as send text
messages to other radios within the same site. Voice consoles, logging recorders, phone gateways,
and data applications cannot communicate to the radios at the site.
Once in Site Trunking, a radio that is involved in calls across multiple sites will only be able to
communicate with other radios within the same site. Communication to and from other sites would be
lost.
NOTE: If there are multiple sites that cover the current location of the radio and one of the sites
enters Site Trunking, the radio roams to another site if within coverage.
