SIST ETS 300 497-2 E2:2003 is the Slovenian adoption of ETS 300 497-2 Edition 2 from ETSI. It specifies an Abstract Test Suite (ATS) for conformance testing of the DECT Common Interface (CI) Medium Access Control (MAC) layer at the Portable radio Termination (PT). In practice, it gives test laboratories and manufacturers a common basis for voluntary testing of DECT Portable Parts against ETS 300 175.

What does SIST ETS 300 497-2 E2:2003 specify?

SIST ETS 300 497-2 E2:2003 specifies the ATS for testing the DECT Portable Part MAC layer, with the test material focused on the PT side of the interface. The document is written as a conformance test specification and is intended to support approval testing with a high probability of air-interface interoperability between different manufacturers' equipment.

The document uses conformance-testing methodology from ISO/IEC 9646 and ETSI testing rules from ETS 300 406. It also points readers to other DECT ETSs for Physical Layer (PHL) testing.

Annex	What it covers
Annex A	The normative ATS in TTCN, including machine-processable and graphical forms
Annex B	The normative specification of the parallel test component LT_MAC
Annex C	The normative Partial PIXIT proforma for DECT MAC
Annex D	The normative Protocol Conformance Test Report (PCTR) proforma for DECT MAC
Annex E	Bibliography

What are the key requirements of SIST ETS 300 497-2 E2:2003?

SIST ETS 300 497-2 E2:2003 defines a remote test method, embedded variant, for MAC testing. Clause 4 is the core of the method, and it matters because it tells the tester where control and observation happen and which component performs each task.

Test architecture and observation points

The Point of Control and Observation (PCO) for MAC testing is at the D-Service Access Point (D-SAP) between MAC and PHL. Events seen there are expressed as Physical Layer - Abstract Service Primitives (PHL-ASPs) with a frame number parameter, so the test system can observe timing and framing in a consistent way.

The Main Test Component (MTC) manages two Parallel Test Components (PTCs): LT_TC and LT_MAC. The MTC creates them, coordinates them, and computes the final verdict, which makes the test execution structure explicit for implementers and laboratories.

Roles of the parallel test components

PTC LT_TC is the observing tester component for the ATS. It only observes the PCO, assigns preliminary verdicts, and does not contain send statements, so the test cases are written as observation-based checks rather than active stimulus from that component.

PTC LT_MAC provides indirect control and observation of the Implementation Under Test (IUT) through the service provider below it. It does not assign verdicts, but it is the part that supports MAC emulation and controlled lower-layer behaviour during the test.

Verdict handling and test execution

Clause 4 defines how final verdicts are derived from the two PTCs. A PASS depends on the expected LT_MAC event and a PASS from LT_TC, while FAIL and INCONC are assigned according to the combinations described in the clause. This matters in practice because the final result is not taken from one component alone.

The dynamic part uses default trees to handle invalid events and to control whether FAIL or INCONC verdicts are possible in a given test step. The document also requires the PTCs to terminate to avoid deadlocks.

Test purposes that are not implemented in the ATS

Clause 5 lists test purposes that are not implemented in the ATS for LT_TC because of the chosen test method or other restrictions. The listed cases cover situations such as not being able to distinguish whether the Portable Termination is unlocked or crashed, and a paging-related case where no procedure can verify the paging Extended Flag.

ATS conventions for writing and maintaining the test suite

Clause 6 sets naming and implementation conventions for the ATS. These conventions matter because they make the test suite readable, maintainable and traceable across tools and conformance logs.

Key rules include:

• uppercase for type definitions
• lowercase for element names, parameter names and field names
• structured identifier prefixes such as TSO_, TSP_, TSC_, TSV_, TCV_ and TC_PT_
• timer naming rules for standardised and non-standardised timers
• labelled verdict assignment so test logs can point back to the exact test table or step

What terms does SIST ETS 300 497-2 E2:2003 define?

• Abstract Test Method (ATM) - the testing approach used to observe and stimulate the DECT MAC layer in a conformance test.
• Abstract Test Suite (ATS) - the set of abstract test cases written for the protocol under test.
• Point of Control and Observation (PCO) - the place where the tester controls or observes the implementation.
• Protocol Implementation Conformance Statement (PICS) - the statement used to show which protocol features the IUT claims to support.
• Protocol Implementation Extra Information for Testing (PIXIT) - extra implementation details needed to run the tests, such as addresses and parameter values.
• Implementation Under Test (IUT) - the DECT implementation being tested for conformance.
• Parallel Test Component (PTC) - a concurrent test component used by the MTC during execution.
• Medium Access Control (MAC) - the DECT layer under test in this part of the standard.

Who uses SIST ETS 300 497-2 E2:2003?

SIST ETS 300 497-2 E2:2003 is used by conformance test laboratories, DECT equipment manufacturers, and approval or compliance teams that need to test the Portable Part MAC layer. It is also used by test managers and clients who complete the PIXIT and PCTR proformas for a test campaign.

In practice, users apply it to prepare test equipment, configure the IUT, run the ATS, record verdicts, and document conformance status. It is especially relevant where the user needs a common, repeatable test basis for DECT approval testing.

What changed in SIST ETS 300 497-2 E2:2003 from the previous edition?

SIST ETS 300 497-2 E2:2003 is the second edition of the conformance test specification. The scope states that it corrects errors found during implementation of the first edition of ETS 300 497-2.

Which standards are used with SIST ETS 300 497-2 E2:2003?

SIST ETS 300 497-2 E2:2003 is built on several DECT and conformance-testing references:

• ETS 300 175-1 to ETS 300 175-8 - provide the DECT Common Interface specification parts for overview, PHL, MAC, DLC, NWK, identities and addressing, security, and speech coding and transmission.
• ETS 300 406 - provides the ETSI methodology for protocol and profile conformance testing.
• ETS 300 474 - provides the Generic Access Profile (GAP) requirement list and the profile-specific ICS proforma, used in the requirements for LT_MAC.
• ETS 300 497-1 - provides the MAC-layer Test Suite Structure (TSS) and Test Purposes (TP), which this ATS follows in naming and structure.
• ETS 300 497-5 - provides the DLC-layer ATS and is the source for the Co-ordination Message (CM) type definitions.
• ISO/IEC 9646-1 to ISO/IEC 9646-7 - provide the international conformance testing framework, including ATS specification, TTCN, test realisation, laboratory and client requirements, protocol profile testing, and ICS.
• 91/263/EEC, TBR 6, TBR 10, TBR 11, TBR 22 - appear in the normative references as related terminal attachment and DECT application requirements.

What does the SIST ETS 300 497-2 E2:2003 document contain?

The document contains a textual description of the ATS method, the ATS conventions, and the test-suite structure for DECT MAC testing. Clause 4 includes a figure of the remote test method, embedded variant, showing the MTC, PTCs, coordination points and the PCO.

Annex A contains the ATS itself in TTCN, with both machine-processable and graphical forms referenced. Annex B contains the MAC emulation actions the test system must support, including actions for CRC faults, RFPI handling, paging, handover and synchronization control.

Annex C gives the Partial PIXIT proforma, with tables for test laboratory data, SUT information, protocol identification and IUT parameter values. Annex D gives the PCTR proforma, including identification, conformance status, test campaign reporting and observation fields.

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 300 497-2: 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) 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 are,
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 (see 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 post ambles, 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 (see annex B) are specified using ETS 300 474 [10].
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 (TP)
This clause gives a list of TP which are not implemented in the ATS for PTC LT_TC (see annex A) due to
the chosen ATM or other restrictions.
Table 1: Untestable TP
Test purpose Reason
TP/DB/BV-00 It is not possible to distinguish, without confusion, if the PT is unlocked or crashed.
TP/DB/BV-02 It is no possible to distinguish, without confusion, if the PT is unlocked or crashed.
TP/PG/BV-00 No procedure can be defined to verify that the Fixed radio Termination (FT) manages
correctly the paging Extended Flag when it transmit pages.
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 [9] 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 the name giving in the declarations part. All type definitions (simple
type definitions, structured type definitions, ASP type definitions and 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 reasons.
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

ETS 300 497-2: February 1998
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.
EXAMPLE 2: TSPC_extended_rf_carriers
If the test suite parameter references a PIXIT item, the letter "X" is added to the standard prefix.
EXAMPLE 3: TSPX_pmid
6.1.1.4 Test case selection expression definition
The test case selection expression identifiers are composed of substrings in lowercase letters, beginning
with the prefix "TCS_". Each substring is separated by an underscore c
