Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS).
The present document is part 2, sub-part 3 of a multi-part deliverable covering the test specifications for High Data Rate
(HDR) Dedicated Short Range Communication (DSRC).
Full details of the entire series can be found in part 2-1 [2].

1 Scope
The present document contains the Abstract Test Suite (ATS) and partial PIXIT proforma to test the Application layer
of ES 200 674-1 [1].
The objective of the present document is to provide test scripts for testing conformance of DSRC-HDR equipment
specified in [1] giving a high probability of inter-operability between different manufacturer's equipment.
All formal test scripts provided in the present document are based on TS 102 708-2-2 [3].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [4], ISO/IEC 9646-2 [5] and
ISO/IEC 9646-5 [6]), ETS 300 406 [7] and ES 201 873-1 [8] specifying the TTCN-3 core language are used as a basis
for the test methodology.

4.1 Protocol layer architecture
The implementation under test is the Application layer of ES 200 674-1 [1]. The System under test includes also the
PHY layer and the LLC layer, which are necessary to perform the IUT tests.
The tester executes the TTCN-3 scripts of the present document, running on an emulated PHY layer.

4.2 Test system architecture
4.2.1 The TTCN-3 test architecture
An abstract architecture for a test system (TS) implementing a TTCN-3 ATS is displayed in figure 2 and also stated in
ES 201 873-5 [9].

Figure 2: The TTCN-3 Abstract Test System Architecture
A TS has two interfaces, the TTCN-3 Control Interface (TCI) and the TTCN-3 Runtime Interface (TRI), which specify
the interface between Test Management (TM) and TTCN-3 Executable (TE) entities, and TE, SUT Adapter (SA) and
Platform Adapter (PA) entities, respectively. Out of these two interfaces the TRI has been standardized in
ES 201 873-5 [9], whereas the specification and implementation of the TCI is in
