SIST EN 300 497-4 V0.3.0:2003 is the Slovenian adoption of ETSI EN 300 497-4 Version 0.3.0 for Digital Enhanced Cordless Telecommunications (DECT). It specifies the Test Suite Structure (TSS) and Test Purposes (TP) for conformance testing of the Data Link Control (DLC) layer in the DECT Common Interface (CI). In practice, it is used to design and run approval-style tests for DECT equipment and to check whether a Portable Part (PP) or Fixed Part (FP) supports the claimed DLC behaviour.
What does SIST EN 300 497-4 V0.3.0:2003 specify?
SIST EN 300 497-4 V0.3.0:2003 specifies the TSS and TP for testing the DECT DLC layer. The focus is on conformance test purposes, not on defining a full Abstract Test Suite (ATS).
The scope says the third edition is a Conformance Test Specification (CTS) for voluntary testing to ETS 300 175. It adds test cases relevant for CAP testing, applies changes needed for the third edition of ETS 300 175, and corrects errors.
The document is organized into these main parts:
- Clause 1 - Scope
- Clause 2 - References
- Clause 3 - Definitions and abbreviations
- Clause 4 - Test Suite Structure (TSS)
- Clause 5 - Test Purposes (TP)
- Bibliography
- History
Clause 4 divides the DLC layer into the Control plane (C-plane) and User plane (U-plane), then splits each plane into functional modules and standard conformance test groups. Clause 5 lists the TP sets for those groups.
What are the key requirements of SIST EN 300 497-4 V0.3.0:2003?
SIST EN 300 497-4 V0.3.0:2003 is built around conformance test purposes for the DLC layer. The most important practical points are the test structure, the naming rules, and the class-by-class behaviours that the TPs cover.
Test structure and test group logic
Clause 4 defines the DLC layer as layer 2b of the DECT protocol stack and separates it into:
- C-plane for signalling
- U-plane for user data
That separation matters because the test purposes are organized by plane and by function, so a tester can locate the relevant behaviour quickly.
Clause 4 also splits the main test groups into:
- CA - Capability tests
- BV - Valid Behaviour tests
- BO - Inopportune Behaviour tests
- BI - Invalid Behaviour tests
These groups are important in practice because they separate basic capability checks from normal operation, unexpected but syntactically correct events, and malformed protocol data units (PDUs).
TP naming and definition conventions
Clause 5 defines each TP by a unique identifier, a reference, an initial condition, a stimulus, and an expected behaviour. It also gives a naming pattern of the form TP<fm>x-<nnn>.
That naming scheme matters because it lets test cases be traced to a specific plane, service class, and test type. For example, the identifier shows whether the TP belongs to C-plane Class A, U-plane Class 1, or another group.
C-plane testing
For the C-plane, the document covers LAPC Class U, Class A, Class B, and the broadcast service Lb.
- Class U TPs check whether the Implementation Under Test (IUT) can send and receive UI frames over MAC connectionless services or an open MAC connection. They also check how the IUT handles erroneous UI frames, such as wrong P bit, NLF bit, LLN, or Service Access Point Identifier (SAPI) values.
- Class A TPs cover link establishment, re-establishment, acknowledgement handling, timer-based retransmission, collision handling, and connection handover procedures. This matters because Class A operation depends on correct link state changes and correct reaction to timers such as
<DL-07>and<DL-04>. - Class B is named in the structure, but no TPs are defined for it in this document.
- Broadcast service Lb TPs check short and long broadcast frame formats and expedited versus normal broadcast message handling with prioritized queuing. These TPs are split by Fixed radio Termination and Portable radio Termination behavior.
U-plane testing
For the U-plane, the document defines TPs for transmission procedures in Classes 0, 1, 2, and 3.
- Class 0 covers correct transmission and reception of U-plane frames.
- Class 1 adds acknowledgement and sequencing checks, including timer
<DLU-01>, window-size behaviour, and rejection of frames with wrong bit values. - Classes 2 and 3 are included in the structure, but no TPs are defined for them in this document.
That distinction matters because Class 1 is the only U-plane class here with detailed sequencing and recovery checks, while Classes 2 and 3 are left without listed TPs.
Relationship to EN 300 175-4
Clause 5 states that all TPs are specified according to EN 300 175-4. It also says that certain Lower Layer Management Entity (LLME) functions are implicitly covered by the C-plane TPs.
That tells the reader where the underlying protocol behaviour comes from and what a test on the C-plane is also expected to exercise indirectly.
What terms does SIST EN 300 497-4 V0.3.0:2003 define?
- Implementation Under Test (IUT) - The equipment being checked against the test purposes.
- Test Suite Structure (TSS) - The tree-like organization of test groups used to arrange the test purposes.
- Test Purpose (TP) - A defined test objective with an initial condition, stimulus, and expected behaviour.
- Protocol Implementation Conformance Statement (PICS) - The statement used to identify which capabilities the implementation claims.
- Protocol Implementation Extra Information for Testing (PIXIT) - Extra implementation information needed to run some test purposes.
- Data Link Control (DLC) layer - The DECT layer under test, called layer 2b in this standard.
- Control plane (C-plane) - The DLC part that carries signalling information.
- User plane (U-plane) - The DLC part that carries user data.
Who uses SIST EN 300 497-4 V0.3.0:2003?
SIST EN 300 497-4 V0.3.0:2003 is used by DECT equipment manufacturers, conformance test laboratories, and approval or certification teams. It helps them check whether an implementation follows the DLC-layer behaviour expected by the DECT Common Interface.
It is also relevant for quality managers and engineering teams who need to map claimed capabilities to test cases, prepare PICS and PIXIT information, or verify interoperability between different manufacturers' equipment. The standard is particularly useful when the task is to build, review, or execute test cases for the Portable Part, Fixed Part, or their DLC protocol entities.
What changed in SIST EN 300 497-4 V0.3.0:2003 from the previous edition?
SIST EN 300 497-4 V0.3.0:2003 is presented as the third edition of the conformance test specification. The scope says it adds CAP-related test cases to support development of the CAP Profile Test Specification, updates the test content to match the third edition of ETS 300 175, and corrects errors.
The history shows earlier publications of ETS 300 497-4 in August 1996 and February 1998 before the Version 0.3.0 publication in 1999.

4.1 Overview
The Data Link Control (DLC) layer is layer 2b of the DECT protocol stack. The separation of the user information from
the DECT signalling data is managed by the allocation of two independent planes:
- the User plane (U-plane); and
- the Control plane (C-plane).

The U-plane is the part of the DLC implementation that is responsible for the transmission of the user data. The U-plane
may provide a series of different services and facilities, grouped into categories (LUx families).
The C-Plane is the second part of DECT DLC and is mainly involved with the transfer of signalling information. It
provides the means to support DECT Connection Oriented, Connectionless and Broadcast services (the broadcast
service exists only at the FT to PT direction). DECT DLC provides three classes of operation (Unacknowledged for
C/L services, Single frame and Multiframe for C/O services).
At the DLC layer, C-plane and U-plane resources are considered as completely independent. The association of C and
U-plane resources to serve a higher layer service (e.g. to setup and maintain a call) is a NWK layer responsibility.
Moreover, no interaction is required between the services provided by each of the planes.
Figure 2 shows the DLC (TSS) including its subgroups and defined for the conformance testing.

4.2 TSS
The test suite is structured as a tree with a first level defined as DLC representing the protocol group "DLC for Portable
Part (PP) and Fixed Part (FP)".
4.3 Test groups
The test groups are organized in three levels. The first level creates two protocol groups representing the protocol plane.
The second level separates the protocol plane in functional modules. The last level contains the standard ISO subgroups
CA, BV, BO and BI.
ETSI
10 ETSI EN 300 497-4 V0.3.0 (1999-10)
4.3.1 Protocol groups
The protocol groups identifies the DECT DLC planes, C-Plane and U-Plane, as defined in EN 300 175 [1] to [8].
4.3.1.1 C-plane
The C-plane protocol group is divided in four functional modules. The first functional module identifies the LAPC
Class U services. The second functional module identifies the LAPC Class A services. The third functional module
identifies the LAPC Class B services. The last functional module identifies the broadcast services Lb.
4.3.1.2 U-plane
The U-plane protocol group is divided in four functional modules. The first functional module identifies the Class 0
transmission procedures. The second functional module identifies the Class 1 transmission procedures. The third
functional module identifies the Class 2 transmission procedures. The last functional module identifies the Class 3
transmission procedures.
4.3.2 Main test groups
The main test groups are the Capability group (CA), the Valid Behaviour group (BV), the inopportune Behaviour group
(BO) and the Invalid Behaviour group (BI).
4.3.2.1 Capability (CA) tests
This test sub group shall provide limited testing of the major IUT capabilities aiming to assure that the claimed
capabilities are correctly supported, in accordance with the PICS.
4.3.2.2 Valid Behaviour (BV) tests
This test sub group shall verify that the IUT reacts in conformity with the standard, on receipt or exchange of a valid
Protocol Data Units (PDUs). Valid PDUs, means, that the exchange of messages and the content of the exchanged
messages are considered as valid.
4.3.2.3 Inopportune Behaviour (BO) tests
This test sub group shall verify that the IUT is capable of a valid reaction, when an inopportune protocol event occurs.
Such an event is syntactically correct but it occurs when it is not expected.
4.3.2.4 Invalid Behaviour (BI) tests
This test sub group shall verify that the IUT reacts in conformity with the standard, on receipt of a syntactically invalid
Protocol Data Unit (PDU).

Expected behaviour
TP Id The TP Id is a unique identifier it shall be specified according to the TP naming
conventions defined in the subclause below.
Reference The reference should contain the references of the subject to be validated by the actual
TP (specification reference, clause, paragraph).
Condition The condition defines in which initial state the IUT has to be to apply the actual TP.
Stimulus The stimulus defines the test event to which the TP is related.
Expected behaviour Definition of the events that are expected from the IUT to conform to the base
specification.
5.1.2 TP naming conventions
The identifier of the TP is built according to table 2.
