24、885 i. The objective of the present document is to provide a basis for conformance tests for TIPHON profile for ITU-T Recommendation H.248 equipment giving a high probability of inter-operability between different manufacturers TIPHON profile for ITU-T Recommendation H.248 equipments. The present do

25、cument covers the procedures described in TS 101 885 i and ITU-T Recommendation H.248 4. The IS0 standard for the methodology of conformance testing (ISO/IEC 9646-1 6 and ISO/IEC 9646-2 7) as well as the ETSI rules for conformance testing (ETS 300 406 5) are used as a basis for the test methodology.

42、d on a Single party (remote) test method for such an IUT when acting as an end entity. However, it is considered that an ATS based on such an approach is of limited use as the only way to speciSl IUT generated PDUs is to use the “implicit send“ statement. Many users of such an ATS would replace the

43、“implicit send“ statements with descriptions of the behaviour at other interfaces. An ATS based on a multi-party test method is considered to be more useful as it is closer to the way a real test suite would be constructed. Such a test method specifies behaviour at multiple network interfaces. One v

44、ery important limitation here is that tests are focussed on one particular interface. Hence the test system is made up of a Main Test Component (MTC) plus one or more Parallel Test Components (PTC), see figure 4. . I UDP/TCP I .

A black box covering these requirements is used in the SUT as a notional U. This notional UT is considered as part o

This means, in particular, that the verdict will only be assigned from the protocol aspects observed on the interface under test (i.e. by the “master“ tester), as it would be observed by a terminal connected to this interface. A failure in the correlation between the protocol at the different interfaces to which the different testers are connected, i.e. in the mechani
