RUA/RUI Radio Behavior

When the radio is logged off and receives RUA accept from the infrastructure without sending logon information, it
indicates book on with assigned logon period timer. The radio sends automatically book on response according to the
terminal settings: Book on Reject — the radio rejects all the book on, Book on Accept — the radio accepts all the
book on.
To log off, use the radio menu. The dispatcher has also the option to log you off using Force Off setting.
The pseudo log on is a state which occurs when the RUA/RUI authenticated radio goes to LST, or infrastructure
accepts the logon with the empty granted assignment period. In this state, the radio has the full functionality available
except some services as forwarding calls. This state is signalized with a specific icon.
The RUA/RUI feature is specified with the following timers:
• Logon Process Timer — defines the amount of time during which the radio awaits log on response from
infrastructure.
• Time Out Warning Timer — defines the amount of time after which the radio displays the warning.
• Logon Period Timer — defines the amount of time during which the radio is logged on.

RUA/RUI Interactions

When you switch from TMO to DMO, the terminal logs off (depending on the codeplug settings). When you switch
from DMO to TMO, the radio initiates the log on process.
You may be RUI-authenticated when out of coverage. In this situation, the radio is in pseudo logged on status. All the
timers are the same as for the logged on user with the coverage. You may also be logged off when out of coverage. In
this situation, the radio is provided with the limited service access. In both cases, if the radio is back in the coverage
area and receives RUA request from SwMI, it prompts you to log on.
If during the emergency operations you receive the force-off, it logs you off without exiting the emergency
operations. As long as the radio is in the emergency operations, the radio display does not indicate any change.
When the radio turns on in the LST, it prompts for the PIN. If the correct PIN is entered, the radio switches to the
pseudo logged on state. When you move to the LST, the radio switches to pseudo logged on state. However, no
prompt for the PIN occurs.
When you change to a different physical terminal, the store and forward report is routed to the radio where you are
currently logged on. When the radio receives store and forward report, it does not display the report, as the reports
have to match the sent SDS. If an SDS consumer report is requested, it is recommended that the receiver sends an
explicit separate SDS message to confirm the message has been received and read. The report is stored together with
the sent SDS in the Outbox, because of that when you log off, delete the messages from the Outbox. When you
change to different physical radio, the previous permanent radio does not receive the report. The status of store and
forward message in the Outbox cannot be updated.
