6.12.3 Site Trunking
Site trunking occurs when a site can no longer participate in wide area trunking. It is
disconnected from other sites and only supports calls with other radios on that site and
cannot route audio to other sites. When site trunking is occurring, the radio searches for
other sites that may provide wide area coverage.
disconnected from other sites and only supports calls with other radios on that site and
cannot route audio to other sites. When site trunking is occurring, the radio searches for
other sites that may provide wide area coverage.
Site trunking ends when a wide area coverage site is located, the current site is operating
again as a wide area coverage site, an out-of-range condition occurs, or the failsoft mode is
entered. The radio can be programmed so that “Site Trnkg” is displayed and/or an alert
tone sounds when site trunking occurs.
again as a wide area coverage site, an out-of-range condition occurs, or the failsoft mode is
entered. The radio can be programmed so that “Site Trnkg” is displayed and/or an alert
tone sounds when site trunking occurs.
SmartZone and P25 trunked systems can be programmed for “Disable Site Trunking
Operation”. The radio is then not allowed to start or operate on a site trunking site. If a site
goes into site trunking, the radio leaves that site’s control channel and attempts to find
another valid wide area site. If no wide area site is available, the radio will continue
searching for another wide area control channel for check for failsoft if failsoft is enabled
and displays “Out-of-Range”. If a site adjacent to the current Home Site was in site
trunking but then enters wide area trunking, it is evaluated to determine if it should move
to that site as a better site.

another site (after a predetermined delay). When the failed site recovers, the radio will
(after a predetermined delay) return to the site.
