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.
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.
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.
6.12.4 Determining Current Site and Searching For New Site
To display the RSSI level of the current site, press the Site Search option button or select
that menu parameter. The display then indicates the current site number as “Site xx” and
the RSSI level as “RSSI xx”. This mode is then automatically exited.
To scroll through the other programmed sites, press and hold the Site Search option button
while “Site xx” or “RSSI xx” is displayed. If site lock is on when site search is entered (see
following), the radio will be locked on the new site when this function is exited.
Note If a site failure occurs, the radio will automatically leave the failed site and register on
another site (after a predetermined delay). When the failed site recovers, the radio will
(after a predetermined delay) return to the site.
