1 Scope
This European Telecommunication Standard (ETS) contains the Test Suite Structure and Test Purposes
(TSS & TP) 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 [7] and ISO/IEC
9646-2 [8]) as well as the ETSI rules for conformance testing (ETS 300 406 [10]) are used as the basis for
the test methodology.
Test specifications for the Physical Layer (PHL), Medium Access Control (MAC) layer, and Network
(NWK) layer are provided in other the DECT standards.

3 Definitions and abbreviations
Refer to ETS 300 175-1 [1] for the main listing of definitions, symbols and abbreviations.
3.1 DECT definitions
For the purposes of this ETS, the following DECT 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.
C-plane: The Control plane of the DECT protocol stacks, which contains all the internal DECT protocol
control, but may also include some external user information.
NOTE 2: The C-plane stack always contains protocol entities up to and including the network
layer.
cluster: A logical grouping of one or more cells between which bearer handover is possible. A cluster
control function controls one cluster.
NOTE 3: Internal handover to a cell which is not part of the same cluster can only be done by
connection handover.

---------------------- Page: 11 ----------------------

SIST ETS 300 497-4 E1:2003
Page 10
ETS 300 497-4: August 1996
connection handover: The internal handover process provided by the DLC layer, whereby one set of
DLC entities (C-plane and U-plane) can reroute 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: "set-up", "data transfer" and "release".
NOTE 6: Connection oriented mode requires no prearranged associations between peer entities
(unlike C/L mode).
DLC broadcast: A simplex "connectionless" mode of transmission from the DLC broadcast entity (Lb) of
one fixed radio termination to the DLC broadcast entities (Lbs) in one or more portable radio terminations.
NOTE 7: The transmitter may disregard the presence or absence of receivers.
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 8: 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 9: 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 the DECT processes and
procedures on the fixed side of the DECT air interface.
NOTE 10: A fixed radio termination only includes elements that are defined in the ETS 300 175.
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 11: 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 12: 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 13: The DECT LLME spans the network layer, the DLC layer, the MAC layer and the
physical layer.

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

SIST ETS 300 497-4 E1:2003
Page 11
ETS 300 497-4: August 1996
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 portable radio termination 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 15: In general, one segment only represents a portion of a complete message.
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 16: 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 Test Suite Structure (TSS)
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). DECT allows the specification of up to 16 LUx families, but only LU1, LU2 and LU5 have been
explicitly defined. Each LUx family uses one or more of the 6 frame formats specified (FU1 - FU6) and of
the four specified transmission classes (0 - 3).
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 (
