Broadcast Call Initiated By User; Timed Talkgroup Change; Broadcast Call - Motorola MTP830 S Product Information Manual

26 | Services and Features
Depending on the codeplug settings, you may be prohibited from initiating ATG calls. In such case, you are still
permitted to initiate an emergency call to an ATG group.

Broadcast Call Initiated by User

This feature allows you to make a Broadcast Call from the radio initiated on the predefined talkgroup. The alias
(message) displayed during Broadcast Call, as well as the call priority and destination address (talkgroup), can be
configured in codeplug. This feature can only be used in TMO mode.
During Broadcast Call, other features are impacted:
• No other services except emergency are allowed (same as in emergency mode)
• Hot Mic functionality cannot be used.
• When Broadcast Call begins, any other ongoing services are terminated.
Note: If the type of the encryption is defined by the BSI feature (radio with a SIM Card), the Broadcast
Call is always clear. Otherwise if the radio uses other encryption service the type of the encryption used for
that Call is up to the encryption settings of that service.
Note: Not all infrastructures support this feature. Consult with your service provider before enabling this
feature.

Timed Talkgroup Change

This feature allows switching between the original and the predefined talkgroup (TMO or DMO) by using a One-
Touch Button.
The radio attaches to the selected, predefined talkgroup only for a specified amount of time (Functional Timer).
After the timer expires, the radio returns to the previously attached, original talkgroup. Returning to the original
talkgroup can also be assigned to the second press action of the button.
Example: A campus university combines four buildings: A, B, C, and D. A security procedure is to raise an
internal alarm for the building and then notify the entire campus. The staff in each campus building
configures radios with three types of talkgroups.
1 Internal Communication Talkgroups – regular talkgroups for the entire campus and individual buildings
to communicate between staff members.
2 Internal Alarm Talkgroups – emergency talkgroups, individual for each building.
3 External Alarm Talkgroup – an emergency talkgroup to alert the entire campus.
The staff in individual buildings uses the dedicated Internal Communication Talkgroups for daily routines
and the Internal Alarm Talkgroup for safety procedures. The campus staff in every building also scans the
External Alarm Talkgroup.
The campus IT administrator assigned in CPS the Timed TG Change function to a One-Touch Button to
switch between the original Internal Communication Talkgroup, and the Internal Alarm Talkgroup. This way
the radio users can immediately switch to the emergency talkgroup and start an internal emergency call.
One of the staff members in building A is in an emergency situation. The person presses the One Touch
Button to switch to the Internal Alarm Talkgroup and starts the emergency call. The other staff members in
building A hear the voice communication on the Internal Alarm Talkgroup. It turns out that the emergency is
serious and one of the building administrators starts the global alarm for all campus buildings.

Broadcast Call

This kind of call enables dispatcher to transmit to all radios in the specific area.
The radio joins calls received with a communication type broadcast and displays a notification that this call is a
broadcast call.
