1 Scope
The present document contains the Abstract Test Suite (ATS) and partial PIXIT proforma to test the Dedicated Short
Range Communication (DSRC); Data Link Control (DLC) layer.
The objective of this test specification is to provide a basis for conformance tests for DSRC equipment giving a high
probability of inter-operability between different manufacturer's equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [4], ISO/IEC 9646-2 [5] and
ISO/IEC 9646-3 [6]) as well as the ETSI rules for conformance testing (ETS 300 406 [3]) are used as a basis for the test
methodology.

4.1 DSRC MAC layer Abstract Test Method (ATM) for OBU
This clause describes the ATM used to test the DSRC MAC layer at the OBU side.
4.1.1 Test architecture
Figure 1: Test architecture for OBU DSRC MAC layer
A parallel testing concept is used, which consists of the following abstract testing parts:
Tester: A test machine that is running a TTCN engine allowing parallel testing and having a
standard DSRC Physical layer.
SUT: System under test.
MTC: Master test component used to perform the test, and start/stop/configure the Lower MAC
Emulation Parallel Test Component.
MAC: A standard DSRC MAC layer to be tested.
Lower_MAC_SAP: Interface between the Lower MAC emulation and MTC. MAC frames, minus their FCS and
flags, are passed via this SAP. In addition, specific frame timing information is passed
upwards on this SAP.
Lower MAC emulation: An DSRC MAC emulation performing some additional functions needed for covering the
test purposes in addition of the behaviour of a standard DSRC MAC layer. In particular,
FCS and flags are added/removed as required, and timing information on received frames
is provided to the MTC.
4.1 DSRC MAC layer Abstract Test Method (ATM) for RSU
This clause describes the ATM used to test the DSRC MAC layer at the RSU side.

Figure 2: Test architecture for RSU DSRC MAC layer
A parallel testing concept is used, which consists of the following abstract testing parts:
Tester: A test machine that is running a TTCN engine allowing parallel testing and having a
standard DSRC Physical layer.
SUT: System under test: Can be RSU or OBU Implementation.
MTC: Master test component used to synchronize the parallel test components and to provide the
final verdict of the test.
PTC1: Parallel test component that is in charge of managing the MAC emulation by using external
function like Start emulation, Stop emulation and some other behaviours needed for
covering all test purposes.
PTC2: Parallel test component that is in charge of analysing the log file to verify the conformity
with the corresponding test purpose at MAC frame level.
MAC: A standard DSRC MAC layer to be tested.
Log File: Log file containing a trace of the physical frame exchange.
PHY-SAP: For TTCN point of view: it is a PCO in which only receive events (without flags, FCS and
after 0 insertion suppression) are observed and no control functions are provided.
CP-MAC: Interface between the MAC emulation and PTC1. Usually a collection of Test Suite
Operation implemented to command the behaviour of the MAC emulation.
MAC emulation: A golden DSRC MAC emulation performing some additional functions needed for
covering the test purposes in addition of the behaviour of a standard DSRC MAC layer.
4.2 DSRC LLC layer Abstract Test Method (ATM)

DSRC MAC and Physical layer.

Test Case: A standard TTCN test case.
LCC: A standard DSRC LLC layer to be tested.
MAC: A standard DSRC MAC layer.
MAC-SAP: To be defined or standard SAP referring to the standard.
4.2 Test strategy
The ATM defined in clauses 4.1.1 and 4.2.1 requires the use of concurrent TTCN, which is specified in
ISO/IEC 9646-3 [6]. The parallel test components PTC1 and PTC2 are, however, seen as two independent entities. This
means that there is no communication or synchronization between the two PTCs during the test.
PTC2 is specified in TTCN (see annex A). Since PTC2 is only observing at the PCO, this ATS does not contain any
send statements. Once the Test Purposes (TP) are fulfilled, the PTC2 terminates, i.e. there are no postambles, unless
required by the TP.
The requirements for PTC1 (see annex B) are specified using EN 12795 [1].
ETSI
14 ETSI TS 102 486-1-3 V1.2.1 (2008-10)
The Master Test Component (MTC) creates the two PTCs (using CREATE operation), PTC1 stimulates the emulation,
and then MTC waits for the two PTCs to terminate (using the DONE event). The final verdict is computed as follows:
- a PASS is assigned if PTC2 returns a PASS verdict and the expected event is received from PTC1;
- a FAIL verdict is assigned if PTC2 returns a FAIL verdict independently of what is received from PTC1;
- an INCONC verdict is assigned if: PTC2 returns an INCONC verdict and the expected event is received from
PTC1, or returns a PASS verdict and an unexpected event is received from PTC1.
5 Untestable Test Purposes (TP)
This clause gives a list of TPs which are not implemented in the Abstract Test Suites due to the chosen Abstract Test
Method or other restrictions.

Test purpose Reason
6 ATS conventions
The ATS conventions are intended to give a better understanding of the ATS but they also describe the conventions
made for the development of the ATS. These conventions shall be considered during any later maintenance or further
development of the ATS.
The ATS conventions contain two clauses, the naming conventions and the implementation conventions. The naming
conventions describe the structure of the naming of all ATS elements. The implementation conventions describe the
functional structure of the ATS.
To define the ATS, the guidelines of the document ETS 300 406 [3] was considered.
6.1 Naming conventions
6.1.1 Declarations part
This clause describes the naming conventions chosen for the elements of the ATS declarations part.
6.1.1.1 General
The following general rules apply for the names given in the declarations part.
Names of ASN.1 types imported from the base standard are preserved.
Predefined types (e.g. BITSTRING [7]) are never used in structured type definitions, ASP type definitions or PDU type
definitions. Simple types are used instead.
All declarations in the test suite are listed in alphabetical order. A different order of listing should be used for only
maintenance reasons.
6.1.1.2 Test suite operations
The test suite operation identifiers are prefixed with "TSO_".
EXAMPLE: TSO_substring.
ETSI
15 ETSI TS 102 486-1-3 V1.2.1 (2008-10)
6.1.1.3 Test suite parameter declarations
If the test suite parameter references a Protocol Implementation Conformance Statement (PICS) item, the test suite
parameter identifiers are prefixed "TSPC_".
EXAMPLE 1: TSPC_extended_rf_carriers.
If the test suite parameter references a PIXIT item, the suite parameter identifiers are prefixed "TSPX_".
EXAMPLE 2: TSPX_pmid.
If the test suite parameter represents a system parameter, the complete name defi
