3.5.2.2
Receiving Emergency Group Calls
The radio receives an Emergency Group Call from a selected pre-programmed group. An appropriate
tone and status icon indicates an incoming call.
3.5.3
Non-Tactical Emergency
In Non-Tactical Emergency, the radio switches to a designated Emergency talkgroup when starting
Emergency Operations. This talkgroup is used for the complete duration of the Emergency Operation.
Changing talkgroups is not allowed at this point.
In Trunked Mode Operation (TMO), the radio can make Emergency Non-Tactical Group Calls without
sending attachments. If configured, the radio assumes implicit attachments after receiving a temporary
address.
In Direct Mode Operation (DMO), the Non-Tactical Emergency proceeds on the same frequency as the
previously selected talkgroup. The service provider can designate any Individual TETRA Subscriber
Identity (ITSI) address to be used for Emergency Operations. This ITSI can be an Open Group -
broadcast address.
After exiting from Non-Tactical Emergency, the radio returns to the previously selected talkgroup.
3.5.4
Emergency Individual Calls (Private or MSISDN)
The Emergency Individual Calls are simplex or duplex calls with emergency priority.
On pressing the Emergency button, the radio initiates an individual call to a provisioned private or
Mobile Station Integrated Services Digital Network (MSISDN) address.
This feature also supports the direct or hook dialing method on simplex and duplex calls. For full
duplex Emergency Individual Calls initiated to an MSISDN address, the default dialing method is
configured to hook. This default dialing method cannot be modified.
In Emergency Individual Calls, the radio rejects all incoming individual calls with nonemergency
priority. These rejected calls are shown as missed calls after the Emergency Individual Calls have
ended.
Emergency Full Duplex Private Calls (FDPC) supports high/low audio state. The audio state is
configurable. You can select the audio state during incoming or outgoing emergency FDPC by toggling
hi or low audio during active Emergency FDPC.
