Page 5I-ETS 300 319: May 1995ForewordThis Interim European Telecommunication Standard (I-ETS) has been produced by the SignallingProtocols and Switching (SPS) Technical Committee of the European Telecommunications StandardsInstitute (ETSI).An ETSI standard may be given I-ETS status either because it is regarded as a provisional solution aheadof a more advanced standard, or because it is immature and requires a "trial period". The life of an I-ETSis limited to three years after which it can be converted into an ETS, have it's life extended for a furthertwo years, be replaced by a new version or, be withdrawn.This I-ETS forms part of a set of I-ETSs completing the documentation of ETS 300 102-1 (ISDN signallingnetwork layer protocol) as specified in ISO/IEC 9646-1 (e.g. conformance testing) as follows:I-ETS 300 314:"Protocol Implementation Conformance Statement (PICS) proformaspecification (basic access, user)";I-ETS 300 315:"PICS proforma specification (primary rate access, user)";I-ETS 300 316:"PICS proforma specification (basic access, network)";I-ETS 300 317:"PICS proforma specification (primary rate access, network)";I-ETS 300 318:"Partial Protocol Implementation eXtra Information for Testing (PIXIT) proformaspecification (basic access, user)";I-ETS 300 319:"Partial PIXIT proforma specification (primary rate access, user)";I-ETS 300 322:"Abstract test suite specification (user)".Proposed announcement dateDate of latest announcement of this I-ETS (doa):31 August 1995IntroductionTo evaluate conformance of a particular implementation, it is necessary to have a statement of whichcapabilities and options have been implemented for a given Open Systems 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 eXtraInformation for Testing (PIXIT) statement based on a proforma, related to a specific abstract test suite andto the relevant means of testing. This PIXIT proforma will normally be provided by the test laboratory tothe client with a request for its completion together with the PICS proforma.The partial PIXIT proforma contained in annex A of this I-ETS is required to be augmented, as necessary,by the test realizer (who produces the executable test suite) and by the test laboratory in order to producethe (non-partial) PIXIT proforma.The completed PIXIT will normally be used in conjunction with the completed PICS, as it adds precision tothe information given in the PICS.PSIST I-ETS 300 319:1996
