Site Trunking

Site trunking occurs when a site is no longer able to
participate in wide-area calls controlled by the zone
controller. Radios operating in site trunking can only
communicate with other radios at that site. All trunking
features are still available. The radio will always be
looking for a wide-area trunking site to lock onto if it
roams into range of one.
