SmartZone Backup Operations
A).Radio operation in Site Trunking
Site trunking occurs when a site is
not 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.
The radio will of course always be
looking for a wide-area trunking site
to lock onto if it roams into range of
one.
1. When a site goes into site trunk-
ing, the radio will receive this
indication and will display
“
SITE TRUNKING
”
2. The display will alternate between
the current trunked mode and the
site trunking display for as long
as the radio remains in site trunk
ing.
3. Users should have a pre-determined
backup Tower site when the System
is in Site Trunking.
Tower prefixes
HO = Houston Tower
HU = Huffman Tower
TO = Tomball Tower
CL = Clodine Tower
AL = Alvin Tower
TM = Tamina Tower
