1 Scope
The present document contains the Test Suite Structure (TSS) and Test Purposes (TP) to test the Digital Enhanced
Cordless Telecommunications (DECT) Data Link Control (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 [10] and ISO/IEC 9646-2 [11]) as well
as the ETSI rules for conformance testing (ETS 300 406 [9]) 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.

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).

Figure 1: DECT protocol stack
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).
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 (e.g. to setup and maintain a call) is a NWK layer responsibility.
Moreover, no interaction is required between the services provided by each of the planes.
Figure 2 shows the DLC (TSS) including its subgroups and defined for the conformance testing.

4.2 TSS
The test suite is structured as a tree with a first level defined as DLC representing the protocol group "DLC for Portable
Part (PP) and Fixed Part (FP)".
4.3 Test groups
The test groups are organized in three levels. The first level creates two protocol groups representing the protocol plane.
The second level separates the protocol plane in functional modules. The last level contains the standard ISO subgroups
CA, BV, BO and BI.

4.3.1 Protocol groups
The protocol groups identifies the DECT DLC planes, C-Plane and U-Plane, as defined in EN 300 175 [1] to [8].
4.3.1.1 C-plane
The C-plane protocol group is divided in four functional modules. The first functional module identifies the LAPC
Class U services. The second functional module identifies the LAPC Class A services. The third functional module
identifies the LAPC Class B services. The last functional module identifies the broadcast services Lb.
4.3.1.2 U-plane
The U-plane protocol group is divided in four functional modules. The first functional module identifies the Class 0
transmission procedures. The second functional module identifies the Class 1 transmission procedures. The third
functional module identifies the Class 2 transmission procedures. The last functional module identifies the Class 3
transmission procedures.
4.3.2 Main test groups
The main test groups are the Capability group (CA), the Valid Behaviour group (BV), the inopportune Behaviour group
(BO) and the Invalid Behaviour group (BI).
4.3.2.1 Capability (CA) tests
This test sub group shall provide limited testing of the major IUT capabilities aiming to assure that the claimed
capabilities are correctly supported, in accordance with the PICS.
4.3.2.2 Valid Behaviour (BV) tests
This test sub group shall verify that the IUT reacts in conformity with the standard, on 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 Inopportune Behaviour (BO) tests
This test sub group shall verify that the IUT is capable of a valid reaction, when an inopportune protocol event occurs.
Such an event is syntactically correct but it occurs when it is not expected.
4.3.2.4 Invalid Behaviour (BI) tests
This test sub group shall verify that the IUT reacts in conformity with the standard, on receipt of a syntactically invalid
Protocol Data Unit (PDU).

TP Id The TP Id is a unique identifier it shall be specified according to the TP naming
conventions defined in the subclause below.
Reference The reference should contain the references of the subject to be validated by the actual
TP (specification reference, clause, paragraph).
Condition The condition defines in which initial state the IUT has to be to apply the actual TP.
Stimulus The stimulus defines the test event to which the TP is related.
Expected behaviour Definition of the events that are expected from the IUT to conform to the base
specification.

5.1.3 Sources of TP definitions
All TPs are specified according to EN 300 175-4 [4]. The functions of the LC entity (frame delimiting, checksum
generation/checking, fragmentation of DLC frames, and routing of frame to/from logical channels) are implicitly
covered by the TP designed for the C-plane.
