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
EXCELLENT	87 and above
GOOD	80 - 86
ACCEPTABLE	74 - 79
POOR	below 74
