SMARTNET/SmartZone/P25 Trunked Features
1
Assume TG1 is selected. If it is the first time this talk group is selected, normal
searching for a control channel occurs according to the hunt methods previously
described.
2
When another talk group is selected, the active valid site for TG1 is stored in EEPROM
memory.
3
The next time TG1 is selected, the following procedure is performed before performing
the normal hunt methods previously described.
a
The last valid site ID and its receive and transmit channel numbers are loaded from
EEPROM memory.
b
The dynamic site list is checked to see if any newer receive/transmit channel
information is available for the last site ID.
c
The best receive/transmit information is used and the radio checks to see if this
control channel is available.
The result of the preceding operation is that the radio has a reasonable chance of finding a
valid site, usually on the first try. This greatly reduces access time, even on systems which
have highly restricted talk group based access.
