Isolated Site Operation; Entering Iso - Motorola L3000 User Manual

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 Phone and Private
Conversation 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 talk-
group or Talkgroup Mode (depending on Scan setting) that the sub-
scriber 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: (while in ISO the
LED indicator is off unless the unit is transmitting. The LED will
be green during those periods).
Phone Mode
Group Call Mode
Private Call Mode
Note: If the portable is powered on in an ISO cell, it will enter the
ISO state if there are no available neighbor cells.
