Page 7ETS 300 267-3: May 1997ForewordThis 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 3 of a multi-part standard covering the Digital Subscriber Signalling System No. one(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) telephony 7 kHz andvideotelephony teleservices, as described below:Part 1:"Protocol specification";Part 2:"Protocol Implementation Conformance Statement (PICS) proforma specification";Part 3:"Test Suite Structure and Test Purposes (TSS&TP) specification for the user";Part 4:"Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing(PIXIT) proforma specification for the user";Part 5:"TSS&TP specification for the network";Part 6:"ATS and partial PIXIT proforma specification for the network".Transposition datesDate of adoption:23 May 1997Date of latest announcement of this ETS (doa):31 August 1997Date of latest publication of new National Standardor endorsement of this ETS (dop/e):28 February 1998Date of withdrawal of any conflicting National Standard (dow):28 February 1998IntroductionThis ETS is divided into seven clauses. Clauses 1 to 3 form the scope, references and abbreviations.Clause 4 contains the test suite structure. Clause 5 contains the complete list of test purposes. Clause 6contains the list of combined test purposes, i.e. test purposes which can be tested together in one testcase. Clause 7 contains the requirements for a generic or abstract test suite to comply with this ETS.It is been assumed that the Implementation Under Test (IUT) already complies with the conformancerequirements associated with the ISDN basic call as defined in ETS 300 102-1. This is specified as arequirement in ETS 300 267-2, clause 5. ETS 300 267-1, subclause 5.1, states that the additional genericrequirements of clause 5 are defined to be compatible with the existing requirements of ETS 300 102-1.The following approach is adopted with regard to specifying test purposes:-resultant states of the IUT are not checked following receipt of messages which comply withETS 300 102-1. Resultant states of the IUT are checked following receipt of messages which donot comply with ETS 300 102-1, e.g. a CONNECT message which contains a Bearer capabilityinformation element;-for ETS 300 267-1, clause 5, the use of the word "assumes", in the case of an IUT at the originatinginterface, is interpreted as meaning that the IUT checks in-band: such test purposes are applicable,therefore, only to IUTs which contain in-band entities.In cases where ETS 300 267-1 specifies that requirements in ETS 300 102-1 shall apply, it is assumedthat, because the IUT already complies with ETS 300 102-1, it also complies with these requirements.However, when specifying the abstract test cases, including test case selection, the requirements inETS 300 102-1 need to be taken into account.SIST ETS 300 267-3:1998

Page 9ETS 300 267-3: May 19971ScopeThis third part of ETS 300 267 is applicable to the stage three of the telephony 7 kHz and videotelephonyteleservices for the pan-European Integrated Services Digital Network (ISDN) as provided by Europeanpublic telecommunications operators at the T reference point or coincident S and T reference point (asspecified in ITU-T Recommendation I.411 [11] by means of the Digital Subscriber Signalling SystemNo. one (DSS1) protocol. ETS 300 267-1 [5] provides the protocol specification and ETS 300 267-2 [6] theProtocol Implementation Conformance Statement (PICS) proforma specification. Stage three identifies theprotocol procedures and switching functions needed to support a telecommunications service (see CCITTRecommendation I.130 [10]).This ETS provides the Test Suite Structure and Test Purposes (TSS&TP) for the user side. It covers theprotocol requirements as defined in ETS 300 267-1 [5] and provides test purposes for the additionalgeneric requirements for basic telecommunication services not defined in ETS 300 102-1 [2](ETS 300 267-1 [5], clause 5), for the telephony 7 kHz teleservice (ETS 300 267-1 [5], clause 6) and forthe videotelephony teleservice (ETS 300 267-1 [5], clause 7).Two types of implementations are covered:-an implementation which supports user requirements at the coincident S and T reference point;-an implementation which supports user requirements for interworking with private ISDNs at theT reference point.2Normative referencesThis ETS incorporates by dated or undated references, provisions from other publications.
