Broadcast Call; Announcement Call; Ptt Double Push; Ptt Queue - Motorola MTP850 S Product Information Manual

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.
Typically, this call type is addressed to the broadcast address (ISSI).
A broadcast call takes precedence over any other call that has the same or lower call priority.
Note: The radio cannot initiate a broadcast call, however, the radio is able to initiate the "broadcast-type"
call restricted to the particular talkgroup using the Announcement Call feature.

Announcement Call

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 Announcement Call, other features are impacted:
• No other services except emergency are allowed (same as in emergency mode)
• Hot Mic functionality cannot be used.
• When Announcement Call begins, any other ongoing services are terminated.
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. Not all infrastructures support this feature. Consult your service provider before enabling it.

PTT Double Push

The PTT double push (D-PTT) feature enables to generate a specific tone sent to radios in the talkgroup. You can
send the tone by pressing twice PTT, or pressing once a One-Touch Button (if configured by the service provider).
After the D-PTT tone is played, you can press and hold the PTT once again to get the permission to talk. Otherwise if
you press the PTT while the D-PTT tone is played, it is ignored. D-PTT tone is not audible on sending radio.
To send the tone (when the feature is enabled), you press the PTT twice in a period defined in CPS. The D-PTT is
triggered only when the radio is in idle or group call mode. The D-PTT tone is not played on the sending radio.
If the PTT is kept pressed after second press and the radio finishes sending the D-PTT tone it allows starting group
call. You are notified of the behavior by the permission to talk tone after D-PTT tone ends. If PTT is released after the
second press, only the D-PTT tone is sent.
Note: The D-PTT tone is sent as voice, hence the receiving radio plays the sound no matter whether the
feature is enabled on it.
You can adjust the D-PTT tone volume level in the speaker/earpiece of the sourcing radio. Disabling all the tones
does not affect the sent tone volume. From the MMI you can change the D-PTT tone to be single, double, or triple.
The tone type can also be changed in the codeplug.

PTT Queue

This feature allows you to configure the response to releasing PTT of the call originating radio. This determines how
to cancel waiting for the call when the infrastructure is busy and your call is queued.
