1 Scope
This European Telecommunication Standard (ETS) contains the Abstract Test Suite (ATS) to test the
DECT DLC layer.
The objective of this test specification is to provide a basis for approval 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 [21], ISO/IEC 9646-2 [22],
ISO/IEC 9646-3 [23] and ISO/IEC 9646-5 [25]) as well as the ETSI rules for conformance testing
(ETS 300 406 [29] and ETR 141 [30]) are used as basis for the test methodology.
Test specifications for the Physical Layer (PHL), Medium Access Control Layer (MAC), and Network Layer
(NWK) are provided in other the DECT standards.
Annex A provides the Tree and Tabular Combined Notation (TTCN) part of this ATS.
Annex B provides the Partial Protocol Implementation eXtra Information for Testing (PIXIT) Proforma of
this ATS.
Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of this ATS.

3 Definitions and abbreviations
Refer to ETS 300 175-1 [1] for the main DECT listing of definitions, symbols and abbreviations. For the
purposes of this ETS, the following definitions apply:
3.1 DECT definitions
C-plane: The control plane of the DECT protocol stacks, which contains all of the internal DECT protocol
control, but may also include some external user information.
NOTE 1: The C-plane stack always contains protocol entities up to and including the network
layer.
DLC data link (DLC link): An association between two DLC layer entities. This can either be one
C-plane association or one U-plane association.
NOTE 2: This is not the same as a MAC connection.
DLC Frame: The format used to structure all messages that are exchanged between DLC layer peer
entities.
NOTE 3: Different DLC frames are used in the C-plane and the U-plane, and there is more than
one format of DLC frame in each plane.
Fixed radio Termination (FT): A logical group of functions that contains all of the DECT processes and
procedures on the fixed side of the DECT air interface.
NOTE 4: A FT only includes elements that are defined in the ETS 300 175 [1] to [9]. This
includes radio transmission elements (layer 1) together with a selection of layer 2 and
layer 3 elements.
flow control: The mechanism that is used to regulate the flow of data between two peer entities.
fragment: One of the service data units that is produced by the process of fragmentation.
NOTE 5: This is not the same as a segment.
fragmentation: The process of dividing a protocol data unit into more than one service data unit for
delivery to a lower layer. The reverse process is recombination.
NOTE 6: This is not the same as segmentation.
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 7: The DECT LLME spans the network layer, the DLC layer, the MAC layer and the
physical layer.
Portable radio Termination (PT): A logical group of functions that contains all of the DECT processes
and procedures on the portable side of the DECT air interface.
NOTE 8: A PT only includes elements that are defined in ETS 300 175 [1] to [9]. This includes
radio transmission elements (layer 1) together with a selection of layer 2 and layer 3
elements.
Radio Fixed Part (RFP): One physical sub-group of a fixed part that contains all the radio end points (one
or more) that are connected to a single system of antennas.
segment: One of the pieces of data that is produced by the process of segmentation.
NOTE 9: In general, one segment only represents a portion of a complete message.

---------------------- Page: 12 ----------------------

SIST ETS 300 497-5 E1:2003
Page 11
ETS 300 497-5: August 1996
segmentation: The process of partitioning one service data unit from a higher layer into more than one
protocol data unit. The reverse process is assembly.
sequencing (sequence numbering): The process of adding a sequence number to a set of data packets
so that the packets can be reassembled in the correct order, regardless of the order in which they are
received. See also segmentation.
U-plane: The user plane of the DECT protocol stacks. This plane contains most of the end-to-end
(external) user information and user control.
NOTE 10: The U-plane protocols do not include any internal DECT protocol control, and it may be
null at the network layer and at the DLC layers for some services.

4 Abstract Test Method (ATM)
This clause describes the ATM used for testing the DECT DLC protocol. It is the embedded variant of
Remote Single (RSE) layer test method. The RSE test method has been selected, because:
- this test method implies no specific requirements from the IUT;
- the Upper Service Access Point (USAP) of the IUT cannot be directly observed;
- the variety of the possible DECT implementations is a serious technical obstacle for the adoption of
a different ATM;
- this test method places the minimum limitations in the realisation of conformance testing.
The embedded variant of the remote test method provides sufficient control of the IUT DLC behaviour,
through NWK layer messages conveyed by DLC frames.
