Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS).
The present document is part 1, 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 1-1 [2].

1 Scope
The present document contains the Abstract Test Suite (ATS) and partial PIXIT proforma to test the "Dedicated Short
Range Communication" (DSRC) "High Data Rate" (HDR) data link layer [1].
The objective of this abstract test specification 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 test specification are based on TS 102 708-1-2 [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.
