18、standards that supports interoperability of autonomous EFC-systems, which includes ISO/TS 17575 parts 1 to 4 that define the EFC context data, their charge reports and their use of communication infrastructure. Within the suite of EFC standards, this conformance evaluation procedure defines the proc
19、ess and tests for conformity evaluation of Front End and Back End that comply with the requirements in ISO/TS 17575-1. This part of ISO/IEC 16407 is intended to assess Front End and Back End capabilities, assess Front End and Back End behaviour, serve as a guide for Front End and Back End conformanc
20、e evaluation and type approval, achieve comparability between the results of the corresponding tests applied in different places at different times, and facilitate communications between parties.

22、t Suite (ATS) to evaluate the conformity of Front End and Back End to ISO/TS 17575-1. The objective of this part of ISO/IEC 16407 is to provide a basis for conformance tests for the Front End and the Back End in Electronic Fee Collection to enable interoperability between different equipment supplie
23、d by different manufacturers. The present abstract test suite is directly derived from ISO/TS 17575-1. 2 Normative references The following referenced documents are indispensable for the application of this document.

Thus, a receive event statement was added in the default behaviour, to ignore messages received on the “pco” port, which have a valid ADU structure and were not handled in the test case behaviour.

43、on: Prefixes are short alphabetic string indicating the type of TTCN-3 element it represents (see table 4 below). Suffixes should not be used except in those specific cases identified in table 4 below. Prefixes and suffixes should be separated from the body of the identifier with an underscore (“_“)
44、. EXAMPLE 1 c_sixteen, t_wait_max. Only module names, data type names and module parameters should begin with an upper-case letter. All other names (i.e. the part of the identifier following the prefix) should begin with a lower-case letter. The start of second and subsequent words in an identifier
45、should be indicated by capitalizing the first character. Underscores should not be used for this purpose. EXAMPLE 2 f_compareDateAndTime. The table 4 below specifies the naming guidelines for each element of the TTCN-3 language indicating the recommended prefix, suffixes (if any) and capitalization.
