Page 5ETS 300 437-2: August 1996ForewordThis European Telecommunication Standard (ETS) has been produced by the Signalling Protocols andSwitching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS is part 2 of a multi-part standard covering the Service Specific Co-ordination Function (SSCF)for support of signalling at the User-Network Interface (UNI) for the Broadband Integrated Services DigitalNetwork (B-ISDN) as described below:Part 1:"Specification of SSCF at UNI [ITU-T Recommendation Q.2130, modified]";Part 2:"Protocol Implementation Conformance Statement (PICS) proforma specification".NOTE:Further parts covering conformance testing will be identified later.Transposition datesDate of adoption of this ETS:23 August 1996Date of latest announcement of this ETS (doa):30 November 1996Date of latest publication of new National Standardor endorsement of this ETS (dop/e):31 May 1997Date of withdrawal of any conflicting National Standard (dow):31 May 1997IntroductionTo evaluate conformance of a particular implementation, it is necessary to have a statement of whichcapabilities and options have been implemented for a given protocol. Such a statement is called aProtocol Implementation Conformance Statement (PICS).SIST ETS 300 437-2:1998

Page 7ETS 300 437-2: August 19961ScopeThis second part of ETS 300 437 provides the Protocol Implementation Conformance Statement (PICS)proforma for the Service Specific Co-ordination Function (SSCF) at the Signalling ATM Adaptation Layer(SAAL) for support of signalling at the User-Network Interface (UNI) for the Broadband IntegratedServices Digital Network (B-ISDN) as specified in ETS 300 437-1 [2] in compliance with the relevantrequirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [4].This PICS proforma applies to the B-ISDN SSCF for UNI signalling and the Service Specific Connection-Oriented Protocol (SSCOP, see ETS 300 436-1 [1]) implementation used to support it. Certain mandatorySSCOP functions are not necessary for the support of UNI signalling, but may be needed to support otherSSCFs. This PICS proforma identifies such mandatory functions as optional for UNI signalling.The supplier of a protocol implementation that is claimed to conform to ETS 300 437-1 [2] is required tocomplete a copy of the PICS proforma provided in annex A of this ETS and is required to provide theinformation necessary to identify both the supplier and the implementation.2Normative referencesThis ETS incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter. For dated references, subsequent amendments to, or revisions of any of these publicationsapply to this ETS only when incorporated in it by amendment or revision. For undated references thelatest edition of the publication referred to applies.[1]ETS 300 436-1: "Broadband Integrated Services Digital Network (B-ISDN);Signalling ATM Adaptation Layer (SAAL); Service Specific Connection-OrientedProtocol (SSCOP); Part 1: Protocol specification [ITU-T RecommendationQ.2110 (1995), modified]".[2]ETS 300 437-1: "Broadband Integrated Services Digital Network (B-ISDN);Signalling ATM Adaptation Layer (SAAL); Service Specific Co-ordinationFunction (SSCF) for support of signalling at the User-Network Interface (UNI);Part 1: Specification of SSCF at UNI [ITU-T Recommendation Q.2130 (1995),modified]".[3]ISO/IEC 9646-1: "Information technology - Open systems interconnection -Conformance testing methodology and framework - Part 1: General concepts".[4]ISO/IEC 9646-7: "Information technology - Open systems interconnection -Conformance testing methodology and framework - Part 7: ImplementationConformance Statements".3DefinitionsFor the purposes of this ETS, the definitions in ISO/IEC 9646-1 [3] and ISO/IEC 9646-7 [4] apply. Inparticular, the following terms defined in ISO/IEC 9646-1 [3] apply:Implementation Conformance Statement (ICS): A statement made by the supplier of an implementationor system claimed to conform to a given specification, stating which capabilities have been implemented.The ICS can take several forms: protocol ICS (PICS), profile ICS, profile specific ICS, and informationobject ICS.Protocol Implementation Conformance Statement (PICS): An ICS for an implementation or systemclaimed to conform to a given protocol specification.PICS proforma: A document, in the form of a questionnaire, which when completed for animplementation or system becomes a PICS.SIST ETS 300 437-2:1998

Page 10ETS 300 437-2: August 1996Annex A (normative):PICS proforma for ETS 300 437-1Notwithstanding the provisions of the copyright clause related to the text of this ETS, ETSI grants thatusers of this ETS may freely reproduce the PICS proforma in this annex so that it can be used for itsintended purposes and may further publish the completed PICS.A.1Guidance for completing the PICS proformaA.1.1Purposes and structureThe purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation ofthe requirements defined in ETS 300 437-1 [2] may provide information about the implementation in astandardized manner.The ICS proforma is subdivided into subclauses for the following categories of information:-guidance for completing the ICS proforma;-identification of the implementation;-identification of the protocol;-global statement of conformance;-SSCOP;-protocol capabilities;-protocol data units;-system parameters;-SSCOP-SSCF UNI protocol capabilities.NOTE:Annex B of ITU-T Recommendation Q.2130 as modified by ETS 300 437-1 [2] is notcovered by the PICS proforma.A.1.2Abbreviations and conventionsThe PICS proforma contained in this annex is comprised of information in tabular form in accordance withthe guidelines presented in ISO/IEC 9646-7 [4].Item columnThe item column contains a number which identifies the item in the table.Item description columnThe item description column describes in free text each respective item (e.g. parameters, timers, etc.). Itimplicitly means "is supported by the implementation?".Status columnThe following notations, defined in ISO/IEC 9646-7 [4], are used for the status column:Mmandatory - the capability is required to be supported.Ooptional - the capability may be supported or not.N/Anot applicable - in the given context, it is impossible to use the capability.O.iqualified optional - for mutually exclusive or selectable options from a set. "i" isan integer which identifies an unique group of related optional items and thelogic of their selection which is defined immediately following the table.ciconditional - the requirement on the capability ("m", "o", "x" or "n/a") depends onthe support of other optional or conditional items. "i" is an integer identifying anunique conditional status expression which is defined immediately following thetable.SIST ETS 300 437-2:1998



Page 11ETS 300 437-2: August 1996Reference columnThe reference column gives reference to ETS 300 437-1 [2], except where explicitly stated otherwise.Support columnThe support column shall be filled in by the supplier of the implementation. The following commonnotations, defined in ISO/IEC 9646-7 [4], are used for the support column:Y or ysupported by the implementationN or nnot supported by the implementationN/A, n/a or - no answer required (allowed only if the status is n/a, directly or after evaluationof a conditional status)NOTE:As stated in ISO/IEC 9646-7 [4], support for a received PDU requires the ability toparse all valid parameters of that PDU. Supporting a PDU while having no ability toparse a valid parameter is non-conformant. Support for a parameter on a PDU meansthat the semantics of that parameter are supported.If this PICS proforma is completed in order to describe a multiple-profile support in a system, it isnecessary to be able to answer that a capability is supported for one profile and not supported for another.In that case, the supplier shall enter the unique reference to a conditional expression, preceded by "?"(e.g. ?3). This expression shall be given in the space for comments provided at the bottom of the table. Ituses predicates defined in the System Conformance Statement (SCS), each of which refers to a singleprofile and which takes the value TRUE if and only if that profile is to be used.EXAMPLE:?3:IF prof1 THEN Y ELSE NValues supported colu
