SIST ETS 300 497-1 E2:2003 is the Slovenian adoption of ETS 300 497-1 Edition 2 from ETSI. It defines the Test Suite Structure (TSS) and Test Purposes (TP) for the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI) Medium Access Control (MAC) layer. Engineers use it as a basis for conformance tests of DECT equipment and for checking MAC-layer behavior against ETS 300 175-3.

What does SIST ETS 300 497-1 E2:2003 specify?

SIST ETS 300 497-1 E2:2003 specifies the TSS and TP used to test the DECT MAC layer. The document is a conformance test specification for voluntary testing to ETS 300 175, and it is aimed at supporting air-interface interoperability between equipment from different manufacturers.

The document is organized into five main clauses and one informative annex:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Definitions and abbreviations
• Clause 4 - Test suite structure
• Clause 5 - Test Purposes (TP)
• Annex A - Bibliography

Annex	What it covers
Annex A	Informative bibliography

Clause 4 arranges the MAC test suite as a tree of protocol groups and test groups. Clause 5 then defines the test purposes, with each TP tied to a reference, an initial condition, a stimulus, and expected behavior.

What are the key requirements of SIST ETS 300 497-1 E2:2003?

SIST ETS 300 497-1 E2:2003 does not define product performance rules in the usual sense. Instead, it defines how MAC-layer conformance tests are structured and what each test purpose is meant to check.

How the test suite is structured

Clause 4 identifies MAC as layer 2a of the DECT protocol stack. The MAC layer is described as providing three service groups:

• broadcast message control
• connectionless message control
• multi-bearer control

This matters because the test suite follows the same service split, so a test lab can select cases by service area instead of reading the whole document as one block.

Clause 4.3 divides the tests into protocol groups and main test groups. The protocol groups are broadcast services, connectionless services, connection oriented services, layer management procedures, and test messages procedures. The main test groups are Capability (CA), Valid Behaviour (BV), and Invalid Behaviour (BI) tests.

In practice, that means:

• CA tests check whether claimed capabilities are present
• BV tests check correct behavior with valid Protocol Data Units (PDUs)
• BI tests check reactions to syntactically invalid PDUs

How TP identifiers are built

Clause 5.1.2 defines the TP naming convention as TP/<fm>/<x>-<nn>. The <fm> code identifies the functional module, <x> identifies the test type, and <nn> is the sequential number.

This is useful in reports and test scripts because the identifier shows at a glance:

• which service area the case belongs to
• whether it is CA, BV, or BI
• the case sequence within that group

What the broadcast and paging tests cover

Clause 5.2 covers broadcast services. The downlink broadcast cases focus on correct transmission of N and Q messages, including static system information, fixed part capabilities, multiframe number, SARI list content, and extended RF carrier information. Some cases apply only when the Fixed radio Termination (FT) supports encryption, SARI, or extended RF.

Clause 5.2.2 covers paging services. The TP set checks short page messages, zero length page messages, the paging Extended Flag, blind slot announcements, and whether a Portable Part (PT) stays locked only under the correct paging conditions.

For a test engineer, this means the standard does not only check that paging messages exist. It checks the details that affect real attachment and idle behavior in the field.

What the connection oriented tests cover

Clause 5.4 covers connection oriented services. The bearer setup cases check PT-initiated basic bearer setup, including behavior with and without wait messages. Bearer handover cases cover intracell and intercell handover for duplex bearers, depending on FT support. Bearer release checks the unacknowledged release procedure. Data transfer checks retransmission in the Automatic Repeat Request (ARQ) window, one-bit numbering, and the rule that a new C segment is not sent before the current one is successfully transmitted.

These cases matter because they exercise the call and traffic handling behavior that users experience as setup speed, continuity, and release correctness.

What the layer management tests cover

Clause 5.5 covers Lower Layer Management Entity (LLME) behavior for MAC. The CA cases check management of protocol constants and timers such as N200, T200, T207, T208, N201, T202, and T203.

In practice, these cases help confirm that timing and retry behavior stay within the expected limits during bearer setup and handover.

Where the test purposes come from

Clause 5.1.3 states that the TPs are specified according to ETS 300 175-3. Some cases also refer to ETS 300 175-6 for identity and addressing behavior. This keeps the TP set anchored to the DECT Common Interface rules it is meant to verify.

What terms does SIST ETS 300 497-1 E2:2003 define?

• Digital Enhanced Cordless Telecommunications (DECT) - The cordless telecommunications system family addressed by the document.
• Medium Access Control (MAC) - The DECT layer that controls radio access, logical channels, and multiplexing on the air interface.
• Test Suite Structure (TSS) - The tree that groups test cases by protocol area and test type.
• Test Purpose (TP) - A defined objective for a test case, with reference, condition, stimulus, and expected behavior.
• Implementation Under Test (IUT) - The DECT equipment being exercised by the conformance tests.
• Protocol Implementation Conformance Statement (PICS) - The statement used to identify the claimed features and capabilities of the implementation.
• Lower Layer Management Entity (LLME) - The management function that spans several lower layers and handles control activities outside normal layer rules.

Who uses SIST ETS 300 497-1 E2:2003?

SIST ETS 300 497-1 E2:2003 is used by DECT equipment manufacturers, test laboratories, and conformity assessors who need to verify MAC-layer behavior. It is also relevant to quality managers and product engineers who must compare an implementation against its PICS and decide which test cases apply.

In practice, the document supports:

• conformance test design
• laboratory validation of DECT PT and FT behavior
• interoperability checking at the air interface
• selection of relevant tests from the TSS and TP set

What changed in SIST ETS 300 497-1 E2:2003 from the previous edition?

SIST ETS 300 497-1 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 300 497-1.

Which standards are used with SIST ETS 300 497-1 E2:2003?

• ETS 300 175-1 to ETS 300 175-8 - These are the DECT Common Interface parts that define the overview, physical layer, MAC layer, DLC layer, NWK layer, identities and addressing, security features, and speech coding/transmission. The TP set validates behavior against this base.
• ETS 300 175-3 - This is the key functional reference for the MAC test purposes and the source of the TP definitions.
• ETS 300 406 - This provides the ETSI methodology for protocol and profile conformance testing.
• ISO/IEC 9646-1 and ISO/IEC 9646-2 - These provide the general conformance testing framework and abstract test suite specification method.
• ISO 7498 - This supplies the OSI reference model terminology used for the Physical Layer.
• 91/263/EEC, TBR 6, TBR 10, TBR 11, and TBR 22 - These are cited as related terminal and attachment requirements for DECT equipment.

What does the SIST ETS 300 497-1 E2:2003 document contain?

The document contains a formal test structure for the DECT MAC layer, plus a set of test purposes written in a consistent TP format. It includes the protocol stack figure, the TSS tree, and the TP naming rules that explain how each test case is identified.

Clause 5 provides detailed test purposes for broadcast services, paging services, connection oriented bearer setup, bearer handover, bearer release, data transfer, and LLME-related management timers and constants. The TP entries show the reference clause, the initial state, and the behavior to verify, which makes them usable for conformance test development and test execution planning.

Annex A gives a bibliography for background reading and related testing documents.

1 Scope
This European Telecommunication Standard (ETS) contains the Test Suite Structure (TSS) and Test
Purposes (TP) to test the Digital Enhanced Cordless Telecommunications (DECT) Medium Access
Control (MAC) layer.
The objective of this test specification is to provide a basis for conformance tests for DECT equipment
giving a high probability of air interface inter-operability between different manufacturer's DECT
equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [10] and
ISO/IEC 9646-2 [11]) as well as the ETSI rules for conformance testing (ETS 300 406 [9]) are used as a
basis for the test methodology.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the definitions given in ETS 300 175-1 [1] apply. In addition, the following
definitions apply:
bearer handover: The internal handover process provided by the Medium Access Control (MAC) layer,
whereby one MAC connection can modify its underlying bearers while maintaining the service provided to
the Data Link Control (DLC) layer.
NOTE 1: Bearer handover is slot based.
broadcast: A simplex point-to-multipoint mode of transmission.
NOTE 2: The transmitter may disregard the presence or absence of receivers.
cell: The domain served by a single antenna(e) system (including a leaky feeder) of one fixed part.
NOTE 3: A cell may include more than one source of radiated Radio Frequency (RF) energy
(i.e. more than one radio end point).
connection handover: The internal handover process provided by the DLC layer, whereby one set of
DLC entities (C-plane and U-plane) can re-route data from one MAC connection to a second new MAC
connection, while maintaining the service provided to the network layer.
NOTE 4: Connection handover is DLC frame based.
Connectionless mode (C/L): A transmission mode that transfers one packet (one self contained unit) of
data from one source point to one (or more) destination points in a single phase.
NOTE 5: Connectionless transmissions require the peer-to-peer associations to be pre-
arranged, and the transmission is unacknowledged at that layer.
Connection Oriented mode (C/O): A transmission mode that transfers data from one source point to one
or more destination points using a protocol based on three phases, "setup", "data transfer" and "release".
NOTE 6: Connection oriented mode requires no prearranged associations between peer entities
(unlike C/L mode).
double simplex bearer: The use of two simplex bearers operating in the same direction on two physical
channels. These pairs of channels always use the same RF carrier and always use evenly spaced slots
(i.e. separated by 0,5 Time Division Multiple Access (TDMA) frame).

Page 9
ETS 300 497-1: February 1998
NOTE 7: A double-simplex bearer only exists as part of a multibearer MAC connection.
duplex bearer: The use of two simplex bearers operating in opposite directions on two physical channels.
These pairs of channels always use the same RF carrier and always use evenly spaced slots (i.e.
separated by 0,5 TDMA frame).
field: A continuous region of data (i.e. adjacent bits) that jointly convey information. Typically, a message
will contain several fields. If data is not continuous then it is defined as two (or more) fields.
Fixed Part (DECT Fixed Part) (FP): A physical grouping that contains all the elements in the DECT
network between the Local Network (LNW) and the DECT air interface.
NOTE 8: A DECT FP contains the logical elements of at least one FT, plus additional
implementation specific elements.
Fixed radio Termination (FT): A logical group of functions that contains all the DECT processes and
procedures on the fixed side of the DECT air interface.
NOTE 9: A FT only includes elements that are defined in the DECT Common Interface (CI)
ETS. This includes radio transmission elements (layer 1) together with a selection of
layer 2 and layer 3 elements.
full slot (slot): One 24th of a TDMA frame which is used to support one physical channel.
half slot: One 48th of a TDMA frame which is used to support one physical channel.
Implementation Under Test (IUT): See ISO/IEC 9646-1 [10];
inter-cell handover: The switching of a call in progress from one cell to another cell.
logical channel: A generic term for any distinct data path. Logical channels can be considered to operate
between logical end points.
Lower Layer Management Entity (LLME): A management entity that spans a number of lower layers,
and is used to describe all control activities which do not follow the rules of layering.
NOTE 10: In DECT, the LLME spans the network layer, the DLC layer, the MAC layer and the
physical layer.
MAC bearer (bearer): MAC bearers are the service elements that are provided by each Cell Site Function
(CSF). Each MAC bearer corresponds to a single service instance to the physical layer. See also simplex
bearer, duplex bearer and double simplex bearer.
MAC connection (connection): An association between one source MAC Multi-Bearer Control (MBC)
entity and one destination MAC MBC entity. This provides a set of related MAC services (a set of logical
channels), and it can involve one or more underlying MAC bearers.
multiframe: A repeating sequence of 16 successive TDMA frames, that allows low rate or sporadic
information to be multiplexed (e.g. basic system information or paging).
paging: The process of broadcasting a message from a DECT fixed part to one or more DECT portable
parts.
NOTE 11: Different types of paging message are possible. e.g., the {REQUEST PAGING}
message orders the recipient to respond with a call setup attempt.
phase: One discrete part of a procedure, where the start and end of the part can be clearly identified (e.g.
by the arrival or dispatch of a primitive).
physical channel (channel): The simplex channel that is created by transmitting in one particular slot, on
one particular RF channel, in successive TDMA frames (see also simplex bearer).

Page 10
ETS 300 497-1: February 1998
NOTE 12: One physical channel provides a simplex service. Two physical channels are required
to provide a duplex service.
Physical Layer (PHL): See ISO 7498 [12].
Portable Part (DECT Portable Part) (PP): A physical grouping that contains all elements between the
user and the DECT air interface. Portable part is a generic term that may describe one or several physical
pieces.
NOTE 13: A DECT portable part is logically divided into one portable termination plus one or
more portable applications.
Portable radio Termination (PT): A logical group of functions that contains all the DECT processes and
procedures on the portable side of the DECT air interface.
NOTE 14: A PT only includes elements that are defined in the DECT CI ETS. This includes radio
transmission elements (layer 1) together with a selection of layer 2 and layer 3
elements.
Protocol Implementation Conformance Statement (PICS): See ISO/IEC 9646-1 [11].
PICS proforma: See ISO/IEC 9646-1 [10].
Radio Fixed Part (RFP): One physical sub-group of a fixed part that contains all the Radio End Points
(REPs) (one or more) that is connected to a single system of antennas.
simplex bearer: A simplex bearer is the MAC layer service that is created using one physical channel.
See also duplex bearer and double simplex bearer.
TDMA frame: A time-division multiplex of 10 ms duration, containing 24 successive full slots. A TDMA
frame starts with the first bit period of full slot 0 and ends with the last bit period of full slot 23.
