ETSIEN 301 002-1 V1.2.4 (1998-10)61ScopeThis first part of EN 301 002 specifies the stage three of the Security tools (SET) procedures for the pan-EuropeanIntegrated Services Digital Network (ISDN) as provided by the European public telecommunications operators at theT reference point or coincident S and T reference point (as defined in ITU-T Recommendation I.411 [2]) by means ofthe Digital Subscriber Signalling System No. one (DSS1) protocol. Stage three identifies the protocol procedures andswitching functions needed to support a telecommunications service (see CCITT Recommendation I.130 [10]).In addition, the present document specifies the protocol requirements at the T reference point where the service isprovided to the user via an intermediate private ISDN.The present document does not specify the additional protocol requirements where the service is provided to the user viaa telecommunications network that is not an ISDN.The SET procedures are a means of providing an appropriate level of security and protection to the user of a giventelecommunication service.Further parts of the present document specify the method of testing required to identify conformance to the presentdocument.The present document is applicable to equipment supporting the SET procedures, to be attached at either side of aT reference point or coincident S and T reference point when used as an access to the public ISDN.2ReferencesReferences 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.2.1Normative references[1]EN 300 196-1: "Integrated Services Digital Network (ISDN); Generic functional protocol for thesupport of supplementary services; Digital Subscriber Signalling System No. one (DSS1) protocol;Part 1: Protocol specification".[2]ITU-T Recommendation I.411 (1993): "ISDN user-network interfaces; Reference configurations".[3]CCITT Recommendation X.208 (1988): "Specification of Abstract Syntax Notation One(ASN.1)".[4]CCITT Recommendation X.219 (1988): "Remote operations: Model, notation and servicedefinition".[5]ITU-T Recommendation Z.100 (1993): "Specification and Description Language (SDL)".SIST EN 301 002-1:2000

The PIN shall consist of aminimum of 4 alphanumeric characters. The maximum number of characters is a network option, but shall not exceed 12alphanumeric characters.Withdrawal of the SET procedures is outside the scope of the present document.The served user may, as a network option , be notified when one or more attempts (but less than the blocking limit Nwhereby all procedures using the PIN are blocked) have been made to use an invalid PIN, either during the operation ofa telecommunication service using the PIN, or during the PIN registration procedure.
