Status Messages

You can select from a list of up to 400 pre-programmed alphanumeric aliases each of which corresponds to a status
value. The valid range of uplink status values is a set of provisioned parameters. If the radio is not enabled with
targeted status, the status value is sent over the air interface to the address of the selected group. The radio recognizes
the general status acknowledgment sent from the SwMI, as well as the negative acknowledgment. In TMO, if no
status acknowledgment or negative acknowledgment is received, the radio retries sending the message. The number
of retries and time to wait before retrying are provisioned parameters. You are notified of the delivery status. As there
is no acknowledgment for DMO status messages, you are notified only of sending the status message. The radio does
not initiate sending of status messages on a traffic channel.
If the radio is provisioned with the targeted status, the status value is sent over the air interface by default to the last
sent target. You have also an option to specify a different individual or group to send the message to. In other words,
you can send an SDS status message to a directly entered ID (for example, ISSI, GSSI, MS-ISDN). If the radio is not
provisioned with the targeted status and you want to send an SDS status message, the following possible actions
apply:
• When the default address type of targeted SDS status is set to Private or Phone, the default address is used as
ISSI, GSSI or ISDN, depending on configuration.
• When the default address type of targeted SDS status is set to group, the selected talkgroup address is used.
• When the targeted SDS status is set to `Dynamic`, the status message is sent to the address configured for the
Dynamic statuses, or defined by a dispatcher (by means of SDS Remote Control).
The radio accepts status messages from addresses it is monitoring. The radio can be preprogrammed with an
appropriate text associated with each status value. The radio notifies when a new status message has been received.
Upon receiving an incoming status message, the stored text corresponding to the status value is extracted and placed
in the text message buffer as a text message. Receiving a status causes the radio to display the message mail screen,
allowing the user quick access to read the message. A received status can be stored in the radio text message buffer.
The PEI provides access for external applications to send and receive status messages.

Shadow Groups (Address Bundle)

The Shadow Groups feature offers a way of sending statuses to multiple destinations or recipients simultaneously.
Each radio can store up to 255 Address Bundles.
Three types of Address Bundles are supported:
• Status Addressing (including emergency alarm)
• GPS LIP Addressing
• RMS/FMS Addressing
Shadow Groups in TMO
Each Address Bundle may contain up to four target addresses (ISSI or GSSI). Each talkgroup may be configured to
send statuses, GPS LIP reports or RMS/FMS messages to a specific Address Bundle.
Shadow Groups in DMO
In DMO the Address Bundle contains one target address (ISSI or GSSI). Each talk group may be configured to send
statuses or GPS LIP reports to a specific Address Bundle.
The Shadow Groups feature may affect Emergency Calls setup time to be slightly elongated.
This is a selling feature.

Text Messages

The radio supports an internal text messaging application using the TETRA SDS Transport Layer. The radio can send
and receive up to 140 bytes of payload data (which can be up to 160 characters, if a 7-bit encoding is used).
Depending on radio settings, for each message in the Inbox , the following options are available:
