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. All trunking features are still available.
The radio will of course always be looking for a wide-area trunking site to lock onto
if it roams into range of one. Also, busied call requests will automatically be
queued at the new site if a site switch is done.
1. When a site goes into site trunking, the radio will receive this indication and
will display “SITE TRUNKING” (MTS 2000 III radios) or “SITE TRK” (MTS
2000 II radios).
2. The display will alternate between the current trunked mode and the site
trunking display for as long as the radio remains in site trunking. A radio-wide
codeplug option will specify whether a site trunking indication will be displayed
or not.
3. The radio will not be considered in site trunking if:
a. The zone controller determines that the site should no longer be in site
trunking and the radio receives this indication, or
b. the radio is out of range, or
c. the radio enters failsoft operation.
Received Signal Strength Indication (RSSI) Text Display
RSSI is used by the radio in Smartzone site switching. It gives an indication of
how strong a signal is being received by the radio. RSSI values are shown below.
When pressing the SRCH button, the radio will display the current site followed by
the RSSI text display.
Signal Rating RSSI Value
