Trunking Operation
Site Trunking
In a SmartZone system, if the zone controller for a particular site fails,
the site enters into a site-trunking operational mode. In this mode of
operation, the user can only communicate with other units at the
same site.
Radios in a SmartZone system can be programmed by a qualified
radio technician to display
STE TRNK (W7) or STE TRUNK (W9) when
site trunking becomes active. The display alternates with the current
mode display as long as the radio remains in site trunking. The radio
also sounds a valid-key chirp when it first detects site trunking.
