PRIVACY PLUS™ ROAMING
OPERATION (MTX150 MODEL
ONLY)
This section outlines the Privacy Plus Roaming
operation of your radio. Please refer to your
authorized Motorola dealer to determine if
the features discussed in this section are
relevant to the system you are operating
on.
Privacy Plus Roaming operation extends
communication beyond the reach of a single
trunked site in a system where wide-area
coverage is needed. Privacy Plus Roaming
operation offers the following capabilities:
• Dynamic Site Assignment - Allows the
zone controller to dynamically assign
channels at sites where required.
• Variable Density Sites - Allows sites to
have varying numbers of channel resources
to accommodate low-density areas as well
as high-density areas.
• Automatic Site Registration/
De-registration - Privacy Plus Roaming
radios automatically send in their unit IDs
and current mode selections upon power
up, power down, site switches, and mode
changes. This allows the zone controller to
know the location of the radio at all times,
and its selected mode.
• Critical Site Assignment - One or more
sites can be designated as a critical site.
This instructs the zone controller to ensure
that every site designated as a critical site
to have available channel resources, before
a channel is granted to a radio requesting
to be identified as a critical site user.
Otherwise, a busy indication will be sent to
the unit.
• Busy Override - This feature allows a
Privacy Plus Roaming radio to send a busy
override request if a busy indication is
issued. The zone controller sends a grant
even though all of the sites may not have
available channel resources.
• Enhanced Automatic Site Switching - A
Privacy Plus Roaming radio will use RSSI
