Page 7ETS 300 711: March 19971ScopeGeneralThis European Telecommunication Standard (ETS) defines the stage 1 description of the Virtual CardCalling (VCC) service. Stage 1 is an overall service description, primarily from the service subscriber's anduser's point of view, but does not deal with the details of the human interface itself. This ETS includesinformation applicable to network operators, service providers and terminal, switch and databasemanufacturers.This ETS specifies the requirements where the service is provided to the user via a telecommunicationsnetwork that is either the pan-European Integrated Services Digital Network (ISDN) or any other PublicSwitched Telephone Network (PSTN) as provided by European public telecommunications operators.The requirements different from those of the basic call where the VCC service is provided to the user via amobile network are outside the scope of this ETS. However, if calls to the VCC service originate orterminate in a mobile network and any special procedure above those for the basic calls has to beperformed, this is be stated in subclause 7.1 dealing with the Interworking between ISDNs, PSTNs andmobile networks.This ETS contains the core requirements for the VCC service which are sufficient to provide a completeservice.This ETS also documents some additional requirements which can be implemented (but do not have to beimplemented).Furthermore, additional functionalities not documented in this ETS may be implemented. Therequirements of which are considered outside the scope of this ETS and consequently outside the scopeof the corresponding stage 2 and stage 3 standards. Such additional functionality may be on a network-wide basis, or particular to one or a group of users. Such additional functionality shall not compromiseconformance to the core requirements of the service.Charging principles are outside the scope of this ETS, unless specific service requirements are stated.These requirements deal with the allocation of certain call charges to particular users.Interactions with services/supplementary services not listed in clauses 8 and 9 are outside the scope ofthis ETS.Interactions between optional VCC service features and ISDN supplementary services are outside thescope of this ETS, unless specific indication is given.Definition and applicabilityThe VCC service allows the user to be automatically charged to the service subscriber's account, which isa telecommunications account subscribed with the service provider or may be optionally an accountmanaged by some other commercial organization, for any outgoing call. The use of nontelecommunications accounts is dependent on agreements between the service provider and suchcommercial organizations. The call shall be free of charge for the line the call originates from. Afteraccessing the service, the user has to enter the card number, a PIN code and the called number.Operation of the VCC service via operators is outside the scope of this ETS.The VCC service is applicable to all telecommunications services using the CCITT RecommendationE.164 [5] numbering plan.This ETS is applicable to the stage 2 and stage 3 standards for the VCC service, where the text indicatesthe status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, as acapability or a possibility), this shall be reflected in the relevant stage 2 and stage 3 standards. Otherwise,the status of a requirement shall be reflected in the relevant standards for the underlying protocols.SIST ETS 300 711 E1:2003



Page 8ETS 300 711: March 1997Furthermore, conformance to this ETS is either met by:-conforming to the stage 3 standards; or-implicitly covered by conforming to the standards for the underlying protocols;with the field of application appropriate to the equipment being implemented. Therefore no method oftesting is provided for this ETS.The validation procedures, general principles and card numbering system shall be in conformance withCCITT Recommendations E.113 [2], E.116 [3] and E.118 [4].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]ETS 300 345 (1994): "Integrated Services Digital Network (ISDN); Interworkingbetween public ISDNs and private ISDNs for the provision of telecommunicationservices; General aspects".[2]CCITT Recommendation E.113 (1992): "Validation procedures for theinternational telecommunication charge card service".[3]CCITT Recommendation E.116 (1992): "International telecommunication chargecard service".[4]CCITT Recommendation E.118 (1992): "The international telecommunicationcharge card".[5]CCITT Recommendation E.164 (1991): "Numbering plan for the ISDN era".3DefinitionsFor the purposes of this ETS, the following definitions apply:account number: Number to identify the service subscriber's account to which the virtual card calls are tobe charged. An account number may be allocated to one or several virtual cards. According to the serviceprovider's implementation, the account number and the card number may be identical.calling user: Entity which originates a call to the VCC service.card number: Digits assigned to a virtual card, in conformance with CCITT Recommendation E.118 [4],permitting the determination of the account number and, if any, of the parameters of the optional servicefeatures.core service feature: Particular service feature fundamental to the telecommunication service, i.e. in theabsence of this service feature, the telecommunication service does not make sense as a commercialoffering to the service subscriber.destination user: Entity to which VCC calls are directed.network operator: Entity which provides the network operating elements and resources for the executionof the VCC service.non-running record: A record containing service subscriber parameters currently not in operation.optional service feature: Service feature added to core feature to optionally enhance a service offering.SIST ETS 300 711 E1:2003

Page 10ETS 300 711: March 19975Description5.1Core requirementsThe VCC service allows the user to be automatically charged to the service subscriber's account, which isa telecommunications account subscribed with the service provider or may be optionally an accountmanaged by some other commercial organization, for any outgoing call. The use of nontelecommunications accounts is dependent on agreements between the service provider and suchcommercial organizations. The call shall be free of charge for the line the call originates from.The user accesses the service by dialling the SAC then, on request, enters the card number, the PIN andthe destination number. Appropriate indications shall be provided to guide the entering and diallingprocess.5.2Optional requirements5.2.1GeneralThe optional requirements contain functionalities additional to the core requirements, that customize theservice according to specific service subscriber's needs. These additional parts may be offered either toall the service provider's customers, or to a group or even to a single customer. In particular, the user mayhave call attempts accepted or rejected according to a set of restrictions.Some optional service features may require extra information to be entered by the user.Some possible optional service features are listed hereafter, but the service provider may offer otheradditional service features.5.2.2Provider's Limitation on Destination (PLD)This feature permits to restrict calls to certain destinations or services (e.g. telephony, facsimile, videotex,videotelephony, etc.) according to service provider's restrictions.For instance, free of charge numbers and destinations whose routing depends on the call origination (forinstance, emergency services) may not be allowed with the VCC service.5.2.3Subscriber's Limitation on Destination (SLD)This feature permits to restrict calls to certain destinations or services (e.g. telephony, facsimile, videotex,videotelephony, etc.) according to service subscriber's choices.5.2.4Time Dependent Control (TDC)This feature enables the service subscriber to specify time intervals (e.g. time of day, day of week, specificdates), that can be used to modify the handling of the call (e.g. acceptance or rejection) according to thepoint in time when the call is placed. The time interval may be specified by the service subscriber.5.2.5Origin Dependent Control (ODC)This feature enables the service subscriber to select the origination from which virtual card calls may bemade. Such selection is based on the geographical area the call originates from.SIST ETS 300 711 E1:2003



Page 11ETS 300 711: March 19975.2.6Credit Limit (floor limit) (CRL)This feature permits to restrict the expenditure per time period (e.g. month) or per call on the accountnumber. The credit limit (also called floor limit) is dependent on an arrangement between the serviceprovider and the service subscriber.When the credit limit has been exceeded, all further calls shall be blocked. When reaching the credit limit,as a service provider option:-the current call may be released immediately; or-the current call may be released after a certain time interval; or-no action may be taken for the current call.In any case, an appropriate indication shall be given to the user.5.2.7Follow-On Calling (FOC)This feature enables the calling user to place subsequent calls without re-entering the authenticationinformation already provided when placing a first call.5.2.8Speed Dialling (SPD)This feature enables a user to define a personal set of abbreviated dialling numbers. The speed calls aresubject to restrictions.5.2.9Pre-Defined Destination (PDD)This feature allows the calling user to place calls to a single pre-defined destination number without beingrequested for the called number.5.2.10Language Selection (LGS)If the user is prompted by messages, this feature permits the user to change the messages language toanother one.5.2.11Customer Profile Management (CPM)This feature enables the service subscriber to manage one or several VCC service handling and billingprofiles (or records) currently not in operation, and to control which record is running or not running.If the service provider does not permit the subscriber to own several profiles, i.e. does not implement non-running records, this feature may allow the service subscriber to modify the profile when in operation.This feature may also permit the modification of the PIN, and the disabling and re-enabling of the makingof calls using the VCC service.A subset of the profile parameters (e.g. PIN, speed dialling lists) may be modified by the service user, ifauthorized by the service subscriber.Customization may require additional authentication procedures that can be provided by the PIN.SIST ETS 300 711 E1:2003



Page 12ETS 300 711: March 19975.2.12Call Logging (LOG)This feature enables the service subscriber to obtain from the service provider detailed information oncalls and/or call attempts placed to the service.The information to be provided may be one or a combination of the following:-calling party number;-destination number;-time and date;-charge;-call result (connected, busy, barred, not answered, etc.);-any service specific information.6Procedures6.1Provision and withdrawalThis service shall be provided by prior arrangement with the service provider.The VCC service shall be withdrawn by the service provider upon service subscriber's request or forservice provider reasons.6.2Normal procedures6.2.1Registration and erasure6.2.1.1Core requirementsThe service provider shall register the service subscriber's profile in the network (running record).
