1 Scope
This ETS contains the Abstract Test Suites (ATS) to test the TETRA Direct Mode Operation (DMO) MS to
MS protocol at layer 3, called Direct Mode Call Control (DMCC) and the MS to MS protocol at layer 2, the
Medium Access Control (MAC) protocol. The DMCC and MAC protocols are specified in
ETS 300 396-1 [1] and in ETS 300 396-3 [2]. The Test Suite Structure (TSS) and Test Purposes (TPs) for
these ATSs are defined in ETS 300 394-4-1 [3].
The objective of these test specifications are to provide a basis for approval tests for TETRA equipment
giving a high probability of air interface inter-operability between different manufacturer's TETRA
equipment.
The ISO standard for the methodology of conformance testing, ISO/IEC 9646-1 [5], ISO/IEC 9646-2 [6],
ISO/IEC 9646-3 [7] and ISO/IEC 9646-5 [8], as well as the ETSI rules for conformance testing,
ETS 300 406 [4] and ETR 141 [9] are used as a basis for the test methodology.
Annex A provides the Tree and Tabular Combined Notation (TTCN) part of these two ATSs.
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.

4 Abstract Test Method (ATM)
4.1 ATM for the DMCC ATS
This clause describes the ATM used for testing the TETRA DMCC protocol. It is the embedded variant of
the remote test method used in Single Party Testing (SPyT) context, as defined in ISO/IEC 9646-2 [6],
clause 11. This test method has been selected, because:
- this test method implies no specific requirements from the Implementation Under Test (IUT);
- the upper Service Access Point (SAP) of the IUT cannot be directly observed;
- the variety of the possible TETRA implementations is a serious technical obstacle for the adoption
of a different ATM;
- this test method places minimum limitations in the realization of conformance testing.
The selected test method is illustrated in figure 1.

4.1.1 Lower Tester (LT)
A LT is located in a remote TETRA test system. It controls and observes the behaviour of the IUT.
4.1.2 Upper Tester (UT)
There is no explicit UT in the remote test method, but the layers above inside the System Under Test
(SUT) are used implicitly for testing the DMCC layer.
4.1.3 Test Coordination Procedures (TCP)
The implicit send events defined by the provider of an implementation in annex B serve the purpose of the
TCP. They are used as an input to the IUT communicating with the UT to initiate test events at the DMCC
protocol layer.
4.1.4 Point of Control and Observation (PCO)
The PCOs are located inside the protocol.
All test events at the PCOs carrying service user data are specified in terms of PDUs. The mapping of the
PDUs to possible Medium Access Control (MAC) layer service primitives is left to the test implementation.
Additionally some Abstract Service Primitives (ASPs) are defined for control and observation purposes.
4.2 ATM for the MAC ATS
This clause describes the ATM used for testing the MAC layer protocol. It is the embedded variant of the
remote test method used in Single Party Testing (SPyT) context, as defined in ISO/IEC 9646-2 [6],
clause 11. This test method has been selected, because:
- this test method implies no specific requirements from the Implementation Under Test (IUT);
- the upper Service Access Point (SAP) of the IUT cannot be directly observed;
- the variety of the possible TETRA implementations is a serious technical obstacle for the adoption
of a different ATM;
- this test method places minimum limitations in the realization of conformance testing.

4.2.2 Upper Tester (UT)
There is no explicit UT in the remote test method, but the layers above inside the System Under Test
(SUT) are used implicitly for testing the MAC layer.
4.2.3 Test Coordination Procedures (TCP)
The implicit send events defined by the provider of an implementation in annex B serve the purpose of the
TCP. They are used as an input to the IUT communicating with the UT to initiate test events at the DMO
MAC layer.
4.2.4 Point of Control and Observation (PCO)
All test events at the PCO carrying service user data are specified in terms of MAC layer PDUs. Only few
Abstract Service Primitives (ASPs) are defined for control or observation purposes. The mapping of the
MAC PDUs into the physical layer frame structure is left to the test implementation.
5 ATS conventions
This clause describes the conventions applied to define the two ATSs and gives the naming conventions
chosen for the different elements of the ATSs.
The ATS conventions are intended to give a better understanding of the ATS but they describe also the
conventions made for the development of the ATS, thus for any later maintenance purposes or further
development of the ATS, the conventions described in this clause shall be considered.
5.1 Naming conventions
5.1.1 Declarations part
This subclause describes the naming conventions chosen for the elements of the ATS declarations part.

Page 14
ETS 300 394-4-2: June 1999
5.1.1.1 Test suite type and structured type definitions
The test suite type and test suite structured type identifiers describe the information elements, and each
whole word included in the name is written in lowercase starting by an uppercase letter:
EXAMPLE: Priority_Level_Type simple type;
SSI_Type simple type;
ITSI_Type structured type.
In the case an abbreviation is included in the declaration name, there is an underscore ("_") before and/or
after it, separating it from the rest of the identifier. This rule with abbreviations apply to all the naming
conventions in the whole test suite.
5.1.1.2 Test suite operations definitions
The test suite operation identifiers are composed of strings in uppercase letters starting by the uppercase
string "TSO_". The different strings in the definition are separated with underscores.
EXAMPLE: TSO_RADIO_LINK_FAILURE.
5.1.1.3 Test suite parameter declarations
The test suite parameter identifiers are composed of strings in uppercase letters starting by the uppercase
string "PIC_" or "PIX_" and separated by underscores.
If the test suite parameter references a PICS item, the prefix "PIC_" is used.
EXAMPLE 1: PIC_INDIVIDUAL_CALL.
If the test suite parameter references a PIXIT item, the prefix "PIX_" is used.
EXAMPLE 2: PIX_MS_ITSI.
Complete names as defined in the specifications are used.
5.1.1.4 Test case selection expression definitions
The naming conventions for the test case selection expression definitions use free text starting with an
uppercase letter. The name of the expression shall explain clearly the selection rule. The test case
selection expressions are generally logical combinations of the PICS element definitions.
5.1.1.5 Test suite constant declarations
The test suite constant identifiers are composed of strings in uppercase letters starting by the uppercase
string "TSC_".
EXAMPLE: TSC_RESERVED2.
Complete names as defined in the specifications are used. However, in the parameters including a dot
character, the dot is replaced by an underscore.
5.1.1.6 Test suite variable declarations
The test suite variable identifiers are composed of string in lowercase letters starting by the lowercase
string "tsv_".
If the test suite variable represents a system parameter or value, the name defined in the specifications is
used. However, in the variables including a dot character, the dot is replaced by an underscore.

5.1.1.7 Test case variable declarations
The test case variable identifiers are composed of strings in lowercase letters starting by the lowercase
string "tcv_".
EXAMPLE: tcv_counter.
5.1.1.8 PCO declarations
The point of control and observation identifiers are composed of three to six capital letters, beginning with
an "L", as there are only LTs.
EXAMPLE: LDMCC Represents a PCO on DMCC for call control PDUs as LT
in the test equipment.
5.1.1.9 Timer declarations
Two kinds of timers can be distinguished:
1) standardized:
Those defined in the standard, e.g.DT303, use the same name as in the standard, beginning with
capital "DT'.
