EN 300 899-1 V1.1.2 (1998-09)4subclause 1.1Replace subclause 1.1 by:1.1ScopeThis first part of ETS 300 899 specifies the interworking between Signalling System No.7 ISDN User Part (ISUP)version 2 as specified in [19] to [36] and Digital Subscriber Signalling System No. one (DSS1) as specified in [1] to[18] and [37] to [39].The interworking between subsequent versions of the ISUP signalling protocol (ISUP version 3, etc.) and the DSS1protocol shall be in accordance with the requirements as contained in this ETS unless explicitly specified otherwise insubsequent versions of the ISUP signalling protocol. This also applies to new services specified in the DSS1 signallingprotocol (e.g. the Selective Call Forwarding services) that make use of the existing procedures in the ISUP protocolThe interworking between the above signalling protocols occurs in an exchange with ISDN local exchange functionalityand is specified in the context of a typical call in a pure ISDN or mixed ISDN/non-ISDN environment.In case of contradictions between the mapping described in the present document and the requirements specified in thecorresponding ISUP and DSS1 standards, the procedures in the ISUP and DSS1 standards apply.subclause 1.2Replace subclause 1.2 by:1.2Normative referencesReferences may be made to:a)specific versions of publications (identified by date of publication, edition number, version number, etc.), inwhich case, subsequent revisions to the referenced document do not apply; orb)all versions up to and including the identified version (identified by "up to and including" before the versionidentity); orc)all versions subsequent to and including the identified version (identified by "onwards" following the versionidentity); ord)publications without mention of a specific version, in which case the latest version applies.A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]ETS 300 052-1: "Integrated Services Digital Network (ISDN); Multiple Subscriber Number(MSN) supplementary service; Digital Subscriber Signalling System No. one (DSS1) protocol;Part 1: Protocol specification".[2]ETS 300 055-1: "Integrated Services Digital Network (ISDN); Terminal Portability (TP)supplementary service; Digital Subscriber Signalling System No. one (DSS1) protocol; Part 1:Protocol specification".[3]ETS 300 058-1: "Integrated Services Digital Network (ISDN); Call Waiting (CW) supplementaryservice; Digital Subscriber Signalling System No. one (DSS1) protocol; Part 1: Protocolspecification".[4]ETS 300 061-1: "Integrated Services Digital Network (ISDN); Subaddressing (SUB)supplementary service; Digital Subscriber Signalling System No. one (DSS1) protocol; Part 1:Protocol specification".SIST EN 300 899-1:2000
