TNP1 Support
The TETRA Network Protocol type 1 (TNP1) allows the user of a Terminal Equipment (such as a
PC) to control TETRA services at the Mobile Terminal via the TETRA Peripheral Equipment
Interface (PEI).
The TETRA services include: Mobility Management, Call Control, Short Data Service (SDS), and
Supplementary Services. In addition, there are commands to access the MT2 configuration and
storage parameters.
To handle the TNP1 interface, the TNP1 application must run on TE2.
The TE2 has to be connected via the RS232 serial communication cable and its application has to
be registered on the MT2.
SDS is available to the TNP1 application running on TE2. The TE2 application can access SDS via
AT commands, or TNP1 on UDP/PPP protocol. This means either AT commands or UDP/PPP, not
both at the same time.
The following menu options are used to configure the terminal's configuration for TETRA Network
Protocol type 1 (TNP1) Support:
27.1 Default Service Profile
This is a list of 256 read-only cells to store in each cell the Default Service Profile for each Protocol
Identifier (PI). The values of the cells are used only while the Point-to -Point (PPP) link is up (for
example AT ON-line). The position of each cell within the list determines its PI. For example, PI for
the first cell is 0 and for the last cell is 255.
Each cell has the structure of information element "SDS (Short Data Service) Control".
The field values may be as follows:
• MT-controlled - only the application in MT will transmit requests or receive responses when it
controls the services.
• TE-controlled - only the application in TE will transmit requests or receive responses when it
controls the services.
• Neither
Values of some PIs cannot be changed, as they are reserved for the future use or restricted by
internal MT application.
27.2 Default Service Profile
This is a list of 256 read-only cells to store in each cell the User-Defined Service Profile for each PI.
The values of the cells are used only while the PPP link is up. The position of each cell within the list
determines its PI.
