Chapter 2: Services and Features
The types of Call-Out alerts are:
Normal
An alert message sent by a dispatcher either to a single radio or to a group of radios.
Storm Plan
An alert message sent by a dispatcher to a group of radios. To raise its reliability, it is sent several
times. You are not able to respond to the Call-Out alert and any key press takes you to the
information phase.
Simple Call-Out
An alert with the functionality similar to full Call-Out but without the information phase. There are
two types of Simple Call-Out:
With user receipt
The Call-Out mode is ended when the acknowledgment timer runs out, or when you select Accept,
Reject, Standby, or reply with a text message.
Without user receipt
The Call-Out mode is ended when the acknowledgment timer runs out, or when you press
Menu/OK to enter CO Menu and select Exit.
Fallback Mode
An alert message that is limited only to voice communication. To initiate this type of Call-Out, press
a One-Touch Buton predefined by your service provider. It can be cleared manually.
NOTICE: Fallback is only possible when the radio is in Local Site Trunking.
Test Call-Out
A special Call-Out alert sent by the dispatcher to test this feature. On receiving the Test Call-Out,
the radio plays a tone and displays Test Call-Out. To respond and clear the alert, enter Call-Out
menu and select Test OK or Send Message.
Only the emergency mode has higher priority than the Call-Out. However, if your service provider
configures Emergency Calls to be ignored during Call-Out mode, the radio rejects them with no
notification. When you receive the alert, the following responses are available.
•
Accept – additional information from the dispatcher is displayed.
•
Reject – display returns to the home display and the talkgroup is set to the one before the Call-Out.
You can address a Call-Out alert by:
•
Individual Short Subscriber Identity (ISSI) – to an individual radio.
•
Group short Subscriber Identity (GSSI) – to a group of recipients.
All incoming and outgoing Call-Out messages are stored in CO Box (Call-Out Box) and can be
managed through the Man-Machine Interface (MMI). You can protect Call-Out messages from being
deleted or from the overwriting policy of the radio. The overwrite policy deletes the oldest one upon
receipt of a new Call-Out message. When a new Call-Out arrives, the new Call-Out overrides the old
Call-Out, even if it has not been responded. An ongoing Call-Out overrides the old one in any phase of
the Call-Out alert. Also, the overwrite policy deletes unprotected Call-Out messages first before
deleting protected ones.
There is a two-level structure for the alerts. First level is the main alert list, and the second one are all
the messages associated with the alerts. Both lists are displayed chronologically with the newest on
top. The capacity of the CO Box is 100 Call-Out alerts and 100 messages (incoming/outgoing).
In normal mode, you can browse the CO Box and read all the Call-Out messages. In the Call-Out
mode, you can only read the ongoing Call-Out messages.
The Call-Out service functions in two main phases:
