Stage three identifies the protocol procedures andswitching functions needed to support a telecommunication service (see CCITT Recommendation I.130 [11]).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 outgoing call barring supplementary services comprise the following services:-Outgoing Call Barring-Fixed (OCB-F) supplementary service;-Outgoing Call Barring-User Controlled (OCB-UC) supplementary service.The OCB-F supplementary service enables a served user to have the network reject calls belonging to certain types,when they are originated by the served user. The served user's ability to receive calls is unaffected by the OCB-Fsupplementary service. The OCB-F supplementary service may operate on all calls belonging to certain types, or just onthose calls associated with specified basic services. The OCB-F supplementary service operates according to therequirements specified by the served user on provision and cannot be activated or deactivated under the control of theserved user.The OCB-UC supplementary service enables a served user to have the network reject calls belonging to certain types,when they are originated by the served user. The served user's ability to receive calls is unaffected by the OCB-UCsupplementary service. The OCB-UC supplementary service may operate on all calls belonging to certain types, or juston those calls associated with specified basic services. The served user can select the barring program(s), activate andlater deactivate them.The OCB supplementary services are applicable to all circuit-switched telecommunications services.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 at least one of the OCB supplementary services, to beattached at either side of a T reference point or coincident S and T reference point when used as an access to the publicISDN.SIST EN 301 001-1:2000

The maximum number of barringprograms is a network option within the range of 1 to 256. A barring program can contain one type of call, or acombination of different types of call to be barred. The defined barring programs are available to all the served users ofthe OCB supplementary service.Unauthorized control of the OCB-UC supplementary service by the served user is protected by the use of a PersonalIdentification Number (PIN).5Operational requirements5.1Provision and withdrawalEach OCB supplementary service shall be provided after prior arrangement with the network provider. Provision of theOCB-UC supplementary service shall include the provision of a PIN.Each OCB supplementary service can be withdrawn separately by the network provider at the subscriber's request, or fornetwork provider reasons.The OCB-F and OCB-UC supplementary services can be provided for all basic services subscribed to by the user, or asa network option, the user can identify particular basic services for which the supplementary service shall be provided.As a network option, the OCB-F and OCB-UC supplementary services can be provided on a per ISDN number basis, orcan be provided to the whole access. The network provider offers both provision options, it shall be a subscriptionoption to choose which of these options applies.When the OCB-UC supplementary service is provided on a per ISDN number basis, and more than one ISDN number isallocated to the served user's access, then, as a network option, the served user may be given the capability to indicatewhether activation or deactivation applies to an indicated number or to all ISDN numbers on the access. This capabilityis to be provided by means of a subscription option.As a network option, the served users of the OCB-UC and OCB-F supplementary services shall be able to have morethan one barring program for a given basic service and ISDN number active simultaneously.SIST EN 301 001-1:2000

Stage three identifies the protocol procedures andswitching functions needed to support a telecommunication service (see CCITT Recommendation I.130 [11]).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 outgoing call barring supplementary services comprise the following services:-Outgoing Call Barring-Fixed (OCB-F) supplementary service;-Outgoing Call Barring-User Controlled (OCB-UC) supplementary service.The OCB-F supplementary service enables a served user to have the network reject calls belonging to certain types,when they are originated by the served user. The served user's ability to receive calls is unaffected by the OCB-Fsupplementary service. The OCB-F supplementary service may operate on all calls belonging to certain types, or just onthose calls associated with specified basic services. The OCB-F supplementary service operates according to therequirements specified by the served user on provision and cannot be activated or deactivated under the control of theserved user.The OCB-UC supplementary service enables a served user to have the network reject calls belonging to certain types,when they are originated by the served user. The served user's ability to receive calls is unaffected by the OCB-UCsupplementary service. The OCB-UC supplementary service may operate on all calls belonging to certain types, or juston those calls associated with specified basic services. The served user can select the barring program(s), activate andlater deactivate them.The OCB supplementary services are applicable to all circuit-switched telecommunications services.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 at least one of the OCB supplementary services, to beattached at either side of a T reference point or coincident S and T reference point when used as an access to the publicISDN.SIST EN 301 001-1:2000

The maximum number of barringprograms is a network option within the range of 1 to 256. A barring program can contain one type of call, or acombination of different types of call to be barred. The defined barring programs are available to all the served users ofthe OCB supplementary service.Unauthorized control of the OCB-UC supplementary service by the served user is protected by the use of a PersonalIdentification Number (PIN).5Operational requirements5.1Provision and withdrawalEach OCB supplementary service shall be provided after prior arrangement with the network provider. Provision of theOCB-UC supplementary service shall include the provision of a PIN.Each OCB supplementary service can be withdrawn separately by the network provider at the subscriber's request, or fornetwork provider reasons.The OCB-F and OCB-UC supplementary services can be provided for all basic services subscribed to by the user, or asa network option, the user can identify particular basic services for which the supplementary service shall be provided.As a network option, the OCB-F and OCB-UC supplementary services can be provided on a per ISDN number basis, orcan be provided to the whole access. The network provider offers both provision options, it shall be a subscriptionoption to choose which of these options applies.When the OCB-UC supplementary service is provided on a per ISDN number basis, and more than one ISDN number isallocated to the served user's access, then, as a network option, the served user may be given the capability to indicatewhether activation or deactivation applies to an indicated number or to all ISDN numbers on the access. This capabilityis to be provided by means of a subscription option.As a network option, the served users of the OCB-UC and OCB-F supplementary services shall be able to have morethan one barring program for a given basic service and ISDN number active simultaneously.SIST EN 301 001-1:2000
