2-24 Services and Feature Description
6866588D21-D Chapter 2 - MTP850 Ex/MTP810 Ex Product Information Manual March 2009
The message can be sent to a target TETRA terminal using SSI addressing, and will be sent with a
request for a received delivery report.
7.4.2 Receiving a Text Message
Upon receiving a text message, the terminal will place the text into a circular buffer. The user will be
notified when a new text message has been received and quick access to read the message will be
provided.
If a delivery report is requested, it will be sent by the terminal upon receipt of the message by SDS-
TL.
If a consumed report is requested, it will be sent when the user reads the message.
Note: If the user reads the message when the terminal is out of service, the report may not be sent.
7.4.3 Saved Text Messages
IMPORTANT: Editing is available only for the full keypad terminal.
The user is given the ability to save incoming or edited (outgoing) text messages. These messages
can be edited and sent and will be only capable of being erased by explicit action from the user.
7.4.4 Timestamp
The timestamp displayed to the user will be extracted from the SDS TL PDU (as specified in the
TETRA SDS Transport Layer Standard - see [Ref 11]). The timestamp will be generated and
inserted into the message by the SwMI.
7.5 SDS Type 4 (Other than Text Message)
7.5.1 Home Mode Display
This feature provides the ability to configure over-the-air, text that will be shown by default on the
terminal’s display.
If this feature is enabled, the terminal displays a text string to the user on the idle display as
specified in Paragraph 18.1.1 "Idle Display". This text can be provisioned in the codeplug.
Upon receipt of an SDS User Defined Type 4 message with a predefined Protocol Identifier for
Home Mode Display (this PI will be provisioned in the codeplug), the terminal will replace the
previous string with the string received in the SDS message. This new text will be used until power
down, or until another is received. If an empty text is received, the terminal will revert to the text
provisioned in the codeplug.
7.5.2 ATS Entry Prompt (a.k.a Predefined Templates)
This feature assists the terminal in sending correctly formatted messages that are intended for
computer applications.
IMPORTANT: Editing is available only for the full keypad terminal.
The terminal user is provided with the ability to select a predefined entry prompt which will define a
message format to assist in the construction of an SDS message. The prompt definition can be
provisioned in the codeplug. The definition defines areas that are ’read-only’ and areas that can be
editable, as well as the type of characters that can be entered (numeric, alpha-numeric or phone
digits). Along with the message definition will also be the address to send the message to.
