ETSI TS 103 238-3 contains the Abstract Test Suite (ATS) for NAT64 technology as defined in RFC 6052 [1] and RFC 6146 [2] which address specific cable industry requirements as defined in ETSI TS 101 569-1 [11] in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [6].

The objective of the present document is to provide a basis for conformance tests for NAT64 technology equipment giving a high probability of inter-operability between different manufacturer's equipment.

The ISO standards for the methodology of conformance testing (ISO/IEC 9646-1 [3] and ISO/IEC 9646-2 [4]) as well as the ETSI rules for conformance testing (ETSI ETS 300 406 [7]) are used as a basis for the test methodology.
