Page 5ETS 300 096: May 1992ForewordThis European Telecommunication Standard (ETS) has been produced by the Signalling Protocols andSwitching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI) andwas adopted having passed through the ETSI standards approval procedure.In accordance with CCITT Recommendation I.130 [1], the following three level structure is used todescribe the supplementary telecommunications services as provided by European publictelecommunications operators under the pan-European Integrated Services Digital Network (ISDN):-Stage 1: is an overall service description, from the user's standpoint;-Stage 2: identifies the functional capabilities and information flows needed to support the servicedescribed in stage 1; and,-Stage 3: defines the signalling system protocols and switching functions needed to implement theservice described in stage 1.This ETS details the stage 2 aspects (functional capabilities and information flows) needed to support theConnected Line Identification Presentation (COLP) and Connected Line Identification Restriction (COLR)supplementary services. The stage one aspects are detailed in ETS 300 094 (1992) [COLP] and ETS 300095 (1992) [COLR], respectively, and the stage three aspects in ETS 300 097 (1992) [COLP] and ETS300 098 (1992) [COLR], respectively.SIST ETS 300 096:1997

Page 7ETS 300 096: May 19921ScopeThis standard defines the stage two of the pan-European Integrated Services Digital Network (ISDN) asprovided by the European public telecommunications operators for the Connected Line IdentificationPresentation (COLP) and Connected Line Identification Restriction (COLR) supplementary services. Stagetwo identifies the functional capabilities and the information flows needed to support the servicedescription. The stage two description also identifies user operations not directly associated with a call(see CCITT Recommendation I.130 [1]).This standard is defined according to the methodology specified in CCITT Recommendation Q.65 [2].This standard does not formally describe the relation between these supplementary service and the basiccall but, where possible, this information is included for guidance.In addition this standard does not specify the requirements where the service is provided to the user via aprivate ISDN. This standard does not specify the requirements for the allocation of defined functionalentities within a private ISDN; it does however define which functional entities may be allocated to a privateISDN.This standard does not specify the additional requirements where the service is provided to the user via atelecommunications network that is not an ISDN.The COLP supplementary service provides the calling party with the possibility to receive identification ofthe connected party.The COLR supplementary service enables the connected party to prevent presentation of its ISDN numberto the calling party.The COLP and COLR supplementary services are applicable to all telecommunication services.This standard is applicable to the stage three standards for the ISDN COLP and COLR supplementaryservices.
The term "stage three" is defined in CCITT Recommendation I.130 [1]. Where the text indicatesthe status of a requirement, i.e. as a strict command or prohibition, as authorisation leaving freedom, as acapability or possibility, this shall be reflected in the text of the relevant stage three standards.Furthermore, conformance to this standard is met by conforming to the stage three standards with the fieldof application appropriate to the equipment being implemented. Therefore, no method of testing is providedfor this standard.2Normative referencesThis standard 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 I.130 (1988): "Method for the characterisation oftelecommunication services supported by an ISDN and network capabilities of anISDN".[2]CCITT Recommendation Q.65 (1988): "Stage 2 of the method for thecharacterisation of services supported by an ISDN".[3]ETS 300 094 (1992): "Integrated Services Digital Network (ISDN); ConnectedLine Identification Presentation (COLP) supplementary service; Servicedescription".SIST ETS 300 096:1997

If these are not available the reason is indicated, via the presentationindicator.Integrated Services Digital Network (ISDN): see CCITT Recommendation I.112 [6], § 2.3 definition 308.International number: an ISDN number structured as specified in § 3.2 (the paragraphs relating tointernational number) of CCITT Recommendation E.164 [8].ISDN number: a number conforming to the numbering plan and structure specified in CCITTRecommendation E.164 [8].National number; National significant number: an ISDN number structured as specified in § 3.2 (theparagraphs relating to national significant number) of CCITT Recommendation E.164 [8].Partial Number: a part of an ISDN number which is significant for distinguishing between addressableentities beyond the network boundary. The partial number digits and the partial number length shall begoverned by the requirements of the direct dialling in and multiple subscriber number supplementaryservices (see ETS 300 062 [12] and ETS 300 050 [13]).SIST ETS 300 096:1997
