Isolated Site Operation
Isolated Site Operation (ISO) allows group call communications to continue
within a single cell site when connectivity to the network is lost by allowing the
cell to operate in a local, one cell only mode. ISO is limited to dispatch
talkgroup calls only. In all modes the display will update to include "-Isoft" on
the first line. Talkgroup communications will be limited to only those units that
are connected to the ISO cell, and only on the talkgroup or Talkgroup Mode that
the subscriber unit last used before the cell entered the ISO state.
Entering ISO
The portable will enter the ISO state when its cell becomes isolated from the
network, assuming the portable has no available neighbor cells. It will display
one of the following screens: (The LED indicator is off in ISO unless the unit is
transmitting. While transmitting, the LED will be green.)
NOTE:If the portable is powered on in an ISO cell, it will enter the ISO state if
there are no available neighbor cells.
