5.2 ICS The ICS is a statement made by the supplier that claims conformance to a certain specification. The ICS states which capabilities have been implemented in the specifications. It also states possible limitations in the implementation of the specification. This document describes testing of implementations according to the following documents: — EN 12834; — ISO 14906. Annex A contains the ICS proforma that shall be used for the ICS. 5.3 IXIT The IXIT is a statement made by the supplier or an implementer of an IUT which contains or references all of the information, in addition to that given in the ICS, related to the DUT and its testing environment. The IXIT enables the test laboratory to run an appropriate test suite against the DUT. In this document, the IXIT specifies the services in the lower communication layers that shall be used to perform the services to be tested. These services are described in EN 12795, EN 12253 and EN 13372, for example. The IXIT shall also contain further information and describe algorithms and procedures that are not specified in the above listed documents but are prerequisites to perform the testing. Examples of such information are: — content of the ApplicationContextMark in the VST, — calculation of access credentials in DSRC services, — use of returnCode in DSRC L7 services and EFC functions, and — calculation of authenticators in EFC functions. Annex B contains the IXIT proforma that shall be used for the declaration of the IXIT.
6.3.2 Functionality of tester 6.3.2.1 Reference beacon The beacon shall be a transparent physical layer interface for DSRC according to European or International Standards. This means that it shall be able to operate standardized data profiles of DSRC links. A simple beacon may be used that only sends and receives frames to or from the DUT. The communication is controlled by the application and data link process of the tester. Beacon parameters, for example, the transmitting power, shall be adjustable by the tester. 6.3.2.2 Application and data link process The tester shall be able to operate the communication link in real time according to data link layer functionality of European or International Standards. The process shall provide the connection to the test control and observation process and shall control the sending and reception of frames to and from the beacon. 6.3.2.3 Test control and observation processes The test control and observation processes shall be implemented on an appropriately equipped computer system. The processes shall comply with the definitions of the application and data link layers defined by European or International Standards and shall be able to generate test suites in reference to ISO 14906. The control process shall provide functionality to configure the test bed, to generate test suites and to perform test suites. EXAMPLE Test suites can be generated in plain ASCII format and can be retrieved by the real-time control process via FTP. While the tests are being performed, all events shall be observed by the PoO process. All results shall be documented, visualized and be made available for detailed analysis.
