Page 7I-ETS 300 491-2: September 1996ForewordPart 2 of this Interim European Telecommunication Standard (I-ETS) has been produced by the TerminalEquipment (TE) Technical Committee of the European Telecommunications Standards Institute (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it can be converted into an ETS, have it's life extended for a furthertwo years, be replaced by a new version, or be withdrawn.This is the second part of an I-ETS which comprise three parts as follows:"Terminal Equipment (TE); Conformance testing for file transfer over the Integrated Services DigitalNetwork (ISDN):Part 1:ETS 300 075 Protocol Implementation Conformance Statement (PICS) proforma;Part 2:ETS 300 075 Test Suite Structure and Test Purposes (TSS&TP);Part 3:Conformance testing for ETS 300 075 restricted by ETS 300 383 - Abstract Testsuite (ATS)".Proposed announcement dateDate of adoption of this I-ETS:30 August 1996Date of latest announcement of this I-ETS (doa):31 December 1996SIST I-ETS 300 491-2 E1:2003

Page 9I-ETS 300 491-2: September 19961ScopePart 2 of this Interim European Telecommunication Standard (I-ETS) specifies the Test Suite Structureand Test Purposes (TSS&TP) for the Telesoftware Data Unit (TDU) layer protocol requirements of ETS300 075 [1], restricted to the test specification for simple file transfer over the ISDN. Only the protocolexchanges aspects are described here, i.e. no Test Purpose concerning the telesoftware application andits specific parameters values is specified here.The ISO/IEC standard for the methodology of conformance testing (ISO/IEC 9646-1 [2],ISO/IEC 9646-2 [3] and ISO/IEC 9646-3 [4]) is used as a basis for the test methodology.2Normative referencesPart 2 of this I-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 this part of the I-ETS only when incorporated in it by amendment or revision.

It may use one or more OSI layers, or only the Physical medium.SIST I-ETS 300 491-2 E1:2003

It is restricted to the use ofETS 300 075 [1] for the EUROFILE transfer profile (ETS 300 383 [5]; e.g. T_Protocol testing inSymmetrical Service).The test suite consists of test groups and test cases. Each test case has a narrowly defined purpose.Within the test suite nested test groups are used to provide a logical ordering of the test cases.Figure 1 shows the TSS for TDU testing. The test suite is hierarchically structured, and is composed of 4levels in the tree structure.SIST I-ETS 300 491-2 E1:2003

Page 14I-ETS 300 491-2: September 19964.3.2PreamblesSome of the specific Test Purposes described below require a preamble to ensure the IUT is in thecorrect state. When requiring a preamble, the test refers to a state which is already defined by a test case.4.3.3PostamblesAfter each test the IUT is brought back to the initial state, using an Abort Request.5Test Purposes presentation5.1IntroductionClause 5 contains the naming conventions and the writing rules for TDU testing. The first part of thisclause describes the naming convention of the Test Purposes referring to the groups to which theybelong, and the second part shows the pattern for the content of Test Purposes, depending on whetherthe IUT is the master or the slave.5.2Test Purpose naming conventionThe identifier of the Test Purpose naming convention takes the following form where each item of thereference name is composed as shown in the table below:Table 1: Test Purpose naming conventionsPattern:TC where:roleMSMasterSlave:category (main test group)12345IT, Basic Interconnection TestsCA, Capability testsBV, Valid Behaviour TestsBO, Inopportune Behaviour TestsBI, Invalid Behaviour Tests:functional aspectIVCETPI, Protocol InteractionPV, Parameter VariationsPC, Parameter CombinationsIE, Inopportune EventTI, Timer Variations:functional units123456789AS, ASsociation establishmentAC, ACcess establishmentDI, File DIrectorySA, SAve fileLO, LOad fileRE, REname fileDE, DElete fileFT, File TRansferTD, Typed-Data:sequential number(00-99)EXAMPLE:TCM3V107 is the number of test case 7, for the Master, to test the validbehaviour of the IUT, with parameter variations, during association phase.SIST I-ETS 300 491-2 E1:2003
