8、 300 309: February 1995 Foreword This final draft Interim European Telecommunication Standard (I-ETS) has been produced by the Signalling Protocols and Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI), and is now submitted for the Voting phase of the

9、ETSI standards approval procedure. An ETSI standard may be given LETS status either because it is regarded as a provisional solution ahead of a more advanced standard, or because it is immature and requires a “trial period“. The life of an I-ETS is limited to three years after which it can be conver

10、ted into an ETS, have its life extended for a further two years, be replaced by a new version or, be withdrawn. This I-ETS forms part of a set of I-ETSs completing the documentation of ETS 300 125 (ISDN data link layer protocol) as specified in ISOAEC 9646-1 (e.g. conformance testing) as follows: I-

11、ETS 300 305: “Protocol Implementation Conformance Statement (PICS) proforma specification (basic access, user)“; I-ETS 300 306: “PICS proforma specification (primary rate access, user)“; I-ETS 300 307: “PICS proforma specification (basic access, network)“; I-ETS 300 308: “PICS proforma specification

12、 (primary rate access, network)“; I-ETS 300 309: “Partial Protocol implementation extra Information for Testing (PIXIT) proforma specification (basic access, user)“; I-ETS 300 310: “Partial PIXIT proforma specification (primary rate access, user)“; I-ETS 300 313: “Abstract test suite specification (

13、user)“. Proposed announcement date Date of latest announcement of this LETS (doa): 3 months after ETSI publication Introduction To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given Open Systems

14、 Interconnection (OSI) protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS). In addition to the PICS, it will be normal for the test laboratory to require a Protocol Implementation extra information for Testing (PIXIT) statement based on a proforma, related to

15、a specific abstract test suite and to the relevant means of testing. This PIXIT proforma will normally be provided by the test laboratory to the client with a request for its completion together with the PICS proforma. The partial PIXIT proforma contained in annex A of this LETS is required to be au

16、gmented, as necessary, by the test realizer (who produces the executable test suite) and by the test laboratory in order to produce the (non-partial) PIXIT proforma. The completed PIXIT will normally be used in conjunction with the completed PICS, as it adds precision to the information given in the

17、 PICS.
