SMARTNET / SmartZone / P25 Trunked Features
With this option enabled on a talkgroup, as the talkgroup affiliates with a site that site is
saved if the radio is changed to a new talkgroup. When the radio moves back to the Wide
Area Scan talkgroup, it will attempt to affiliate on the saved site before looking for a new
site.
6.12.8.1 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 (or 15) adjacent sites 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,
the radio searches the list of control channels programmed into the radio.
Full Spectrum CC Scan - If the two preceding methods do not locate a control
channel, every channel available to the radio is searched.
6.12.8.2 Talkgroup Steering through System Access Permissions
To use system channel resources more efficiently, some system operators are using system
access permissions to steer certain talkgroups to particular sites. For example, a police
department may be allowed to use only Site 1, and a public works department may be
allowed to use only Site 2.
The problem with this operation is that every time a different talkgroup is selected, the
access permission may be different and a different site may need to be accessed. This
could result, in a worst case, in a delay of up to 30 seconds in finding a new site. This
could occur if there are no valid sites for the new talkgroup in the dynamic site list.
6.12.9 Initialize System Info on System Change
A programmable option feature allows a radio to be configured with multiple profiles, for
multiple sites with the same System ID and WACN. The feature can be used where a radio
system may have multiple sites but uses the same system ID and WACN at all sites, but
different control channel frequencies at each site.
If this option is enabled, multiple profiles can be created with different unit IDs or control
channel frequencies for P25 Trunking systems that contain the same System ID and
WACN.
If this option is disabled, multiple system personalities can be created for the same system.
This is the default setting.
