Emergency Group Call; Emergency Private Call; Emergency Ms-Isdn Call - Motorola MTP830 S Feature User Manual

If the radio user wishes to finish Emergency Call, a confirmation pop-up appears to avoid unintentional disconnects.

3.6.1 Emergency Group Call

While in the Emergency Mode, you are able to initiate and receive an Emergency Group Call. This special call is
initiated by pressing the EMERGENCY button.
If a radio receives an incoming Group Call with emergency priority, the display shows that an Emergency Group Call
has been received, and a special audio alert is played. Your radio automatically switches to the Emergency Mode.
The audio for an Emergency Group Call always goes through the speaker (high audio), even if the low audio
is selected.
An Emergency Group Call can be configured as:
• Non-tactical — call on a talkgroup predefined by your service provider. The group might be different than
the one selected initially. After exiting from non-tactical Emergency Mode the radio is attached to the group
that was selected before initiating the non-tactical call. When in non-tactical Emergency Mode, you are
not able to switch talkgroups. DGNA messages have no impact during non-tactical Emergency Mode but
only after exiting the non-tactical Emergency Mode.
• Tactical — call on the currently selected talkgroup.
Emergency Group Calls in TMO
If the radio enters Emergency Mode while the Emergency Broadcast Call is active, the radio continues on the call
without initiating any calls and sends an Emergency Alarm. The behavior depends on your service provider settings.
When the Emergency Group Call you participate in terminates, your radio can behave in several ways, depending on
your service provider settings:
• If you are the call initiator, the radio can either stay in the Emergency Mode, or return to TMO Mode.
• If you are not the call initiator, the radio always returns to TMO Mode.
Emergency Group Calls in DMO
In DMO, Emergency Group Calls through a gateway are supported.

3.6.2 Emergency Private Call

The Emergency Private Calls are Simplex or Duplex Private Calls with emergency priority. On pressing the
EMERGENCY button, the radio initiates a Private Call with emergency call priority to the provisioned address. No
Emergency Alarm is sent and your radio does not enter the Emergency Mode. This pseudo emergency state (all user
indication and rejection of other services) ends as soon as the Emergency Private Call ends.

3.6.3 Emergency MS-ISDN Call

The Emergency MS-ISDN calls are simplex or duplex telephone calls with emergency priority. On pressing the
EMERGENCY button, your radio initiates an Emergency MS-ISDN call to the predefined MS-ISDN number.
The MS-ISDN call type (simplex or duplex) is predefined by your service provider.
