Page 5ETS 300 081: February 1993ForewordThis European Telecommunication Standard (ETS) has been produced by the Terminal Equipment (TE)Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS makes major reference to a number of CCITT Recommendations provided in the Normativereferences Clause (Clause 2), and can only be applied when considered together with elements of theCCITT Recommendations.Annex A is normative and provides additional session layer requirements plus the necessary amendmentsneeded to CCITT Recommendation T.62 [3]. Annex B is also normative and sets down test procedures forend-to-end protocols with reference to prETS 300 017 [8] together with CCITT Recommendation T.64 [7].SIST ETS 300 081 E1:2003

Page 7ETS 300 081: February 19931Scope and field of applicationThis ETS refers to the low layer protocols to be used in the Integrated Services Digital Network (ISDN), asdefined in CCITT Recommendation T.90 [1] together with ETS 300 080 [2].This ETS specifies the end-to-end protocols to be used between two end systems as defined in CCITTRecommendation T.62 [3].In addition, it defines the octet-string to be interchanged based on the coding scheme, as defined inCCITT Recommendation T.61 [4].This ETS gives a general tool for a manufacturer-independent compatible text communication betweenend systems over the ISDN, based on the Telematic protocol stack.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 the latestedition of the publication referred to applies.[1]CCITT Recommendation T.90 (1992): "Characteristics and protocols forterminals for telematics services in ISDN".[2]ETS 300 080 (1992): "Integrated Services Digital Network (ISDN); ISDN lowerlayer protocols for telematic terminals".[3]CCITT Recommendation T.62 (1988): "Control procedures for teletex andGroup 4 facsimile services".[4]CCITT Recommendation T.61 (1988): "Character repertoire and codedcharacter sets for the international teletex service".[5]CCITT Recommendation T.60 (1988): "Terminal equipment for use in theteletex service".[6]CCITT Recommendation T.62 bis (1988): "Control procedures for teletex and G4 facsimile services based on Recommendations X.215 and X.225".[7]CCITT Recommendation T.64 (1988): "Conformance testing procedures for theteletex Recommendations".[8]Draft prETS 300 017: Terminal Equipment (TE); "Test procedures for Teletex".3Definitions and abbreviationsFor the purpose of this ETS, the following definitions apply:Teletex document: octet strings encoded according to the primary and supplementary sets of graphiccharacter and the primary and supplementary sets of control functions as defined in CCITTRecommendation T.61 [4], §4.1 and §4.2, representing only characters out of the basic graphic characterrepertoire and the basic control function repertoire as defined in CCITT Recommendation T.61 [4], §3.2and §3.3, and complying with the basic page formats as defined in CCITT Recommendation T.60 [5],§4.2.The other terms and all abbreviations used throughout this ETS are as defined in the ETSs/CCITTRecommendations provided in Clause 2.SIST ETS 300 081 E1:2003
