SIST ETS 300 393-10 E1:2003 is the Slovenian standard identical to ETS 300 393-10 Edition 1 from ETSI. It defines the Specification and Description Language (SDL) model of the Terrestrial Trunked Radio (TETRA) Packet Data Optimized (PDO) air interface. In practice, it gives a formal behavioral model for the TETRA PDO Mobile Station (MS) side of the air interface.

What does SIST ETS 300 393-10 E1:2003 specify?

SIST ETS 300 393-10 E1:2003 specifies the SDL model of the TETRA PDO Air Interface. The document is organized into Scope, References, Abbreviations, and General, with a foreword and history section around the main clauses.

The foreword places this standard in a five-part ETS series for TETRA PDO:

• Part 1: General network design
• Part 2: Air Interface (AI)
• Part 7: Security
• Part 10: SDL model of the Air Interface (AI)
• Part 11: Protocol Implementation Conformance Statement (PICS) proforma specification

What are the key requirements of SIST ETS 300 393-10 E1:2003?

The central purpose of SIST ETS 300 393-10 E1:2003 is to model TETRA PDO air-interface behavior in SDL. The most practical point is that the SDL model supports protocol understanding and implementation, but the textual specification remains authoritative if the model and the text differ.

Model scope and precedence

The standard defines the SDL model for the TETRA PDO MS. It is built from the description in ETS 300 393-2, and any conflict is resolved in favor of the textual specification.

In practice, implementers use this rule when the formal model and the descriptive standard do not match exactly. It prevents the SDL diagrams from overriding the written protocol definition.

What is included in the model

SIST ETS 300 393-10 E1:2003 says the model comes from the SDL validation model for TETRA PDO, with validation-only detail removed. It mainly keeps SDL blocks and processes, and includes SDL procedures when their function is not obvious from the name alone.

For readers, this means the document is focused on the parts of the model needed to understand the protocol behavior, not on every validation detail.

Relationship to the air-interface description

The standard keeps the names of signals and parameters aligned with ETS 300 393-2 where SDL permits it. It also reflects the limitation that SDL is not used here for bit-exact data description.

In practice, this helps engineers cross-check the model against the textual air-interface standard, while remembering that SDL is a behavioral notation.

Protocol entity structure

The General clause says each SDL protocol entity is made up of two main parts: a protocol part and a formatter part. The protocol part handles the service access points above the entity and the PDU interface to the next lower protocol entity. The formatter part converts between PDUs and N - 1 Service Primitives (SP).

This structure matters because it shows where protocol handling ends and service conversion begins, which is useful when implementing or tracing message flow.

Scope limits

SIST ETS 300 393-10 E1:2003 focuses on the TETRA PDO MS model. It does not define base station functionality in the SDL model, and concurrent services for the TETRA protocol stack are outside its scope.

That tells a reader to use this standard for MS-side modeling, not as a complete description of all TETRA network functions.

What terms does SIST ETS 300 393-10 E1:2003 define?

• Specification and Description Language (SDL) - The formal language used to describe protocol behavior and structure.
• Mobile Station (MS) - The TETRA terminal side modeled by this standard.
• Packet Data Optimized (PDO) - The TETRA profile concerned with optimized packet data transfer.
• Protocol Data Unit (PDU) - The unit exchanged by protocol entities.
• Service Access Point (SAP) - The interface point between protocol layers.
• Service Primitive (SP) - The service interaction passed across a service interface.
• Connection Oriented Network Protocol (CONP) - One of the SDL model parts named in the document.
• Specific ConnectionLess Network Protocol (SCLNP) - Another SDL model part named in the document.

Who uses SIST ETS 300 393-10 E1:2003?

SIST ETS 300 393-10 E1:2003 is used by TETRA protocol engineers, SDL modelers, and implementers of the PDO MS air interface. It is also useful for verification teams comparing protocol behavior against the written air-interface specification.

In practice, the document supports:

• protocol design and review
• implementation of TETRA PDO MS behavior
• model-based analysis and validation
• checking how PDUs map to service interactions
