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: 10 ----------------------

SIST ETS 300 497-1 E2:2003
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: 11 ----------------------

SIST ETS 300 497-1 E2:2003
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.

4.2 Test suite structure (TSS)
The test suite is structured as a tree with a first level defined as MAC representing the protocol group
"MAC for PP and FP".
4.3 Test groups
The test groups are organized in three levels. The first level creates five protocol groups representing the
protocol services and the standard ISO main group BI. The second level, if the third level exists, separates
the protocol services in functional modules. The last level in each branch contains the standard ISO
subgroups CA, BV and BI.
4.3.1 Protocol groups
The protocol groups identifies the DECT MAC services: broadcast services, connectionless services,
connection oriented services, layer management procedures, test messages procedures, as defined in
ETS 300 175, Parts 1 to 8 [1] to [8].

Page 13
ETS 300 497-1: February 1998
4.3.1.1 Broadcast services
The broadcast services protocol group is divided in three functional modules. The first functional module
identifies the downlink broadcast services. The second functional module identifies the paging services.
The last functional module identifies the non-continuous broadcast services.
4.3.1.2 Connectionless services
The connectionless services protocol group is divided in two functional modules. The first functional
module identifies the downlink connectionless services. The last functional module identifies the uplink
connectionless services.
4.3.1.3 Connection oriented services
The connection oriented services protocol group is divided in five functional modules. The first functional
module distinguishes the bearer setup subgroup. The second functional module distinguishes the
connection modification subgroup. The third functional module distinguishes the bearer handover
subgroup. The fourth functional module distinguishes the bearer release subgroup. The last functional
module distinguishes the data transfer subgroup.
4.3.1.4 Layer management procedures
The layer management procedures protocol group contains directly the main test groups.
4.3.1.5 Test messages procedures
The test messages procedures protocol group contains directly the main test group CA.
4.3.2 Main test groups
The main test groups are the capability group, the valid behaviour group and the invalid behaviour group.
4.3.2.1 Capability (CA) tests
This test sub group shall provide limited testing of the major IUT capabilities aiming to insure that the
claimed capabilities are correctly supported, according to the PICS.
4.3.2.2 Valid Behaviour (BV) tests
This test sub group shall verify that the IUT reacts in conformity with the ETS, after receipt or exchange of
a valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of
the exchanged messages are considered as valid.
4.3.2.3 Invalid Behaviour (BI) tests
This test sub group shall verify that the IUT reacts in conformity with the ETS, after receipt of a
syntactically invalid PDU.
