SMARTNET / SmartZone / P25 Trunked Features
6.13.5 Auto Site Search
Auto site search automatically searches and selects the best site available. User selection
of sites is not available in Auto Site mode.
of sites is not available in Auto Site mode.
6.13.6 ZoneFail Site Lock
This is an optional feature that can be enabled only by factory programmed. It does not
require any special inputs from the infrastructure to operate. This feature is intended to
prevent some of the confusion resulting from a site controller failure. When this occurs, all
sites go into the Site Trunking mode and radios continue to roam normally according to
RSSI level. The result is that the various radios selected by a particular talk group may be
operating on different sites and are unable to talk to each other (see Section 6.13.2 for
more Site Trunking information).

With the Zone Fail Site Lock feature enabled, the radio continues to roam normally when
the system zone controller is active. However, if the zone controller fails, this is detected
and the Zone Fail Site Lock mode is entered. The only site the radio is then allowed to
operate on is its home site. If its home site is not available, “OUT-OF-RANGE” is
displayed. A zone controller failure is detected by determining that every site in the
dynamic site list is in Site Trunking. Currently, this condition must be detected for at least
1 minute for the Zone Fail Site Lock mode to be selected.

The result of this operation is that all radios with the same programmed home site are
forced to the home site to communicate which ensures that they can continue to
communicate. If the home site is not available, the Out-of-Range condition tells the user to
attempt communication on another system or by some other means.

6.13.7 P25 Wide Area Scan
This feature is intended to enhance roaming performance, especially when system level
steering through radio or talk group permissions is used.

6.13.8 Normal P25 and SmartZone Control Channel Hunt
The following control channel search methods are normally used to find a control channel:
Short Hunt - The dynamic array of 7 adjacent sites (SmartZone) or 15 adjacent sites
(P25 Trunking) is searched. This list is saved on power down and loaded again at
power up. It is erased whenever parameters are downloaded to the radio.
(P25 Trunking) is searched. This list is saved on power down and loaded again at
power up. It is erased whenever parameters are downloaded to the radio.
Long Hunt - If no valid control channel is located by the preceding short hunt method,
