SIST ETS 300 497-3 E2:2003 is the Slovenian adoption of ETS 300 497-3 Edition 2 from ETSI. It specifies the Abstract Test Suite (ATS) for conformance testing of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI) Medium Access Control (MAC) layer at the Fixed radio Termination (FT). Engineers, test labs, and approval teams use it to run DECT MAC tests in a consistent TTCN-based format and to record the results with the matching PIXIT and PCTR forms.
What does SIST ETS 300 497-3 E2:2003 specify?
SIST ETS 300 497-3 E2:2003 specifies the ATS used to test the DECT FT MAC layer. The standard is written as a Conformance Test Specification for voluntary testing to ETS 300 175, and it is aimed at approval testing and interoperability checking between equipment from different manufacturers.
The document is organized around the test method, the ATS conventions, and the supporting test documentation. Physical layer test specifications are handled in other DECT standards, while this part focuses on MAC-layer testing at the FT.
| Annex | What it covers |
|---|---|
| Annex A | The normative ATS for PTC LT_TC, including machine-processable and graphical TTCN forms |
| Annex B | The normative specification of PTC LT_MAC |
| Annex C | The normative partial PIXIT proforma for DECT MAC |
| Annex D | The normative PCTR proforma for DECT MAC |
| Annex E | Bibliography |
What are the key requirements of SIST ETS 300 497-3 E2:2003?
The standard’s core requirement is to use the abstract test method described in Clause 4. SIST ETS 300 497-3 E2:2003 uses a remote test method, embedded variant, with a single-party testing concept. In practice, that means the test system controls and observes the implementation through defined access points rather than by informal manual checks.
How the test system is structured
SIST ETS 300 497-3 E2:2003 defines the Point of Control and Observation (PCO) at the D-SAP between the MAC layer and the Physical layer. Events at this point are expressed as Physical Layer Abstract Service Primitives (PHL-ASPs) with a frame number parameter added. This matters because the test cases depend on frame-level observation, not just logical messages.
The standard also defines two co-ordination points:
- CP_TC between the Main Test Component (MTC) and PTC LT_TC
- CP_MAC between the MTC and PTC LT_MAC
CP_TC is used for coordination between test functions, while CP_MAC carries MAC-ASPs and DLC Protocol Data Units (DLC-PDUs). The practical effect is that the MTC can drive the test in a controlled way and keep the two parallel test components aligned.
How verdicts are assigned
SIST ETS 300 497-3 E2:2003 gives a clear verdict strategy in Clause 4. PTC LT_TC observes the PCO and assigns only preliminary verdicts; the MTC computes the final verdict. A PASS depends on both the expected PTC_TC outcome and the expected event from PTC_MAC, a FAIL is driven by a FAIL from PTC_TC, and an INCONC verdict is used when the observed coordination result does not match the expected one.
In practice, this keeps the result logic explicit. Test laboratories can trace why a case passed, failed, or became inconclusive instead of relying on an undocumented tool decision.
What the ATS does not cover
Clause 5 lists untestable test purposes. One named example is the paging Extended Flag behavior when the FT transmits pages. This tells the user that the ATS is not a complete behavioral description of the product, but a defined and bounded test set.
How the ATS is written and named
Clause 6 defines the ATS conventions for the lower tester part, PTC LT_TC. These conventions matter for maintenance, tool use, and repeatability. The document standardizes naming for test suite operations, parameters, constants, variables, timers, ASPs, PDUs, coordination messages, test cases, test steps, defaults, labels, and abbreviations.
In practical terms:
- standardized timers keep the same protocol names and also use min, max, and implemented values
- test case identifiers show the functional module and test type, such as capability, valid behavior, or invalid behavior
- verdict assignments are labeled so the conformance log can show exactly where a result was set
What PTC LT_MAC must support
Annex B requires PTC LT_MAC to meet, at minimum, the requirements with profile status M in ETS 300 474. It also specifies actions the test system shall support through coordination messages. These actions include generating specific error conditions, triggering handover procedures, and starting or stopping test case synchronization.
For a test lab, this means the MAC emulation must be able to provoke the required DECT behaviors, not just passively observe them. That is what makes the ATS executable for conformance assessment.
What terms does SIST ETS 300 497-3 E2:2003 define?
- Abstract Test Suite (ATS) - The collection of test cases and supporting definitions used to test protocol behavior in a standardized way.
- Abstract Test Method (ATM) - The testing approach used by the ATS, including how the test system interacts with the implementation under test.
- Main Test Component (MTC) - The test component that creates the parallel test components, manages coordination, and computes the final verdict.
- Parallel Test Component (PTC) - A concurrent test component used to observe or stimulate the implementation during a test case.
- Implementation Under Test (IUT) - The protocol implementation being checked against the standard.
- Point of Control and Observation (PCO) - The defined place where the test system controls and observes protocol behavior.
- Protocol Implementation Conformance Statement (PICS) / Partial Protocol Implementation Extra Information for Testing (PIXIT) - The PICS states what the implementation claims to support, and the PIXIT supplies test-specific implementation details needed to run the ATS.
- Protocol Conformance Test Report (PCTR) - The report template used to record the conformance assessment results.
Who uses SIST ETS 300 497-3 E2:2003?
Test laboratories use SIST ETS 300 497-3 E2:2003 to execute DECT MAC conformance tests and complete the PCTR. They rely on it when setting up the test environment, choosing PIXIT values, and documenting verdicts.
Manufacturers of DECT fixed radio equipment use it to check how their implementations behave against the DECT MAC requirements. This helps during development, integration, and pre-compliance testing.
Quality managers and approval teams use it to review whether the implementation was tested with the expected method and whether the report documentation is complete. The standard is also relevant to anyone preparing the test system emulation described for PTC LT_MAC.
What changed in SIST ETS 300 497-3 E2:2003 from the previous edition?
This second edition corrects errors found during implementation of the first edition of ETS 300 497-3. It is identified as Edition 2 of the DECT Common Interface Test Case Library, Part 3.

Figure 1: Remote test method, embedded variant
A single-party testing concept is used, which consists of the following abstract testing functions:
PCO: the Point of Control and Observation (PCO) for MAC Layer testing is located at
the D-Service Access Point (D-SAP) between the MAC layer and the Physical
layer. All test events at the PCO are specified in terms of Physical Layer
Abstract Service Primitives (PHL-ASPs) (frame number parameter added).
CP_TC: Co-ordination Point Test Case (CP_TC) is located between the Main Test
Component (MTC) and Parallel Test Component (PTC) LT_TC in the test
system. It is used for passing co-ordination messages between these two
testing functions.
CP_MAC: Co-ordination Point MAC (CP_MAC) is located between the MTC and PTC
LT_MAC in the test system. It is equivalent to the PCO used for Data Link
Control (DLC) layer testing in part 6 of this ETS. All co-ordination messages at
this CP are specified in terms of MAC-ASPs and DLC Protocol Data Units
(DLC-PDUs).
Page 11
ETS 300 497-3: February 1998
PTC LT_TC: the Lower Tester Parallel Test Component LT_TC (PTC LT_TC) is located in
the test system. It makes restricted use of the PCO by only observing the test
events in both directions. It assigns preliminary verdicts (the MTC assigns the
final verdict).
NOTE: This restricted use of the PCO is a non-ISO/IEC 9646-2 [14] application of the PCO.
PTC LT_MAC: the Lower Tester Parallel Test Component LT_MAC (PTC LT_MAC) is located
in the test system. It provides indirect control and observation of the
Implementation Under Test (IUT) during test execution, via the underlying
service-provider. It does not assign any verdicts.
MTC: the Main Test Component (MTC) is located in the test system. It is responsible
for creating and terminating the PTCs, managing the co-ordination points
CP_TC and CP_MAC, and computation of the final test case verdict.
Upper layers: no explicit Upper Tester (UT) exists in the test system. However, the System
Under Test (SUT) (upper layers) needs to carry out some UT functions to
achieve some effects of test co-ordination procedures.
The primitives used at the PCO (physical SAP - DSAP) are defined according to ETS 300 175-2 [2],
clause 7 and associated subclauses.
The co-ordination messages used at CP_MAC co-ordination point are abstract primitives including
protocol data units and frames. The abstract primitives (MAC ASPs) are defined according to
ETS 300 175-3 [3], clause 8 and associated subclauses. Two abstract primitives for starting and stopping
the synchronization between the main test component and the parallel test component LT_MAC are
added for the needs of the tester. The protocol data units (DLC C-plane PDUs) are defined according to
ETS 300 175-4 [4], clause 7 and associated subclauses. The frames (DLC U-plane frames) are defined
according to ETS 300 175-4 [4], clause 12 and associated subclauses.
4.2 Test strategy
The ATM defined in subclause 4.1 requires the use of concurrent TTCN, which is specified in Amendment
1 of ISO/IEC 9646-3 [15]. The parallel test components PTC_TC and PTC_MAC is, however, seen as two
independent entities. This means that there is no communication or synchronization between the two
PTCs during the test.
PTC_TC is specified in TTCN (annex A). Since PTC_TC is only observing at the PCO, this ATS does not
contain any send statements. Once the Test Purposes (TP) are fulfilled, the PTC_TC terminates, i.e. there
are no postambles, unless required by the TP. No explicit co-ordination messages is exchanged at
CP_TC. To simplify the TTCN test cases, the underlying service provider has been assigned the task of
frame numbering. Consequently, a frame parameter has been added to some of the PHL-ASPs.
The requirements for PTC_MAC (annex B) are specified using ETS 300 474 [11].
The Main Test Component (MTC) creates the two PTCs (using CREATE operation), stimulates the
PTC_MAC (using MAC ASPs at CP_MAC) and then waits for the two PTCs to terminate (using the DONE
event). The final verdict is computed as follows:
- a PASS is assigned if PTC_TC returns a PASS verdict and the expected event is received from
PTC_MAC at CP_MAC;
- a FAIL verdict is assigned if PTC_TC returns a FAIL verdict independently of what is received from
PTC_MAC at CP_MAC;
- an INCONC verdict is assigned if PTC_TC returns an INCONC verdict and the expected event is
received from PTC_MAC at CP_MAC; or returns a PASS verdict and an unexpected event is
received from PTC_MAC at CP_MAC.

5 Untestable Test Purposes (TPs)
This clause gives a list of TPs which are not implemented in the ATS for PTC LT_TC (annex A) due to the
chosen abstract test method or other restrictions.

6 ATS Conventions (only applicable for PTC LT_TC)
The ATS conventions are intended to give a better understanding of the ATS but they also describe the
conventions made for the development of the ATS. These conventions shall be considered during any
later maintenance or further development of the ATS.
The ATS conventions contain two clauses, the naming conventions and the implementation conventions.
The naming conventions describe the structure of the naming of all ATS elements. The implementation
conventions describe the functional structure of the ATS.
To define the ATS, the guidelines of the documents ETS 300 406 [10] and ETR 141 were considered.
6.1 Naming conventions
6.1.1 Declarations part
This subclause describes the naming conventions chosen for the elements of the ATS declarations part.
6.1.1.1 General
The following general rules apply for name giving in the declarations part. All type definitions (Simple type
definitions, Structured type definitions, ASP type definitions and Protocol Data Unit (PDU) type definitions)
shall be written in uppercase.
All element names (Structured type definition), parameter names (ASP type definition) and field names
(PDU type definition) shall be written in lowercase.
Predefined types (e.g. BITSTRING[8]) are never used in structured type definitions, ASP type definitions
or PDU type definitions. Simple types are used instead.
All declarations in the test suite are listed in alphabetical order. A different order of listing should be used
for only maintenance reason.
6.1.1.2 Test suite operations definition
The test suite operation identifiers are composed of substrings in lowercase letters, except for standard
prefix "TSO_". Each substring is separated by an underscore character ("_").
EXAMPLE: TSO_substring.
6.1.1.3 Test suite parameter declarations
The test suite parameter identifiers are composed of substrings in lowercase letters, except for the
standard prefix "TSP_". Each substring is separated by an underscore character ("_").
EXAMPLE 1: TSP_t_wait
If the test suite parameter references a Protocol Implementation Conformance Statement (PICS) item, the
letter "C" is added to the standard prefix.
