This European Telecommunication Standard (ETS) defines the stage two of the Call Forwarding Unconditional (CFU) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications operators. Stage two identifies the functional capabilities and the information flows needed to support the stage one service description. The stage two description also identifies user operations not directly associated with a call (see CCITT Recommendation 1.130 [3]).<\/p>\n
This ETS is specified according to the methodology defined in CCITT Recommendation 0.65 16].<\/p>\n
This ETS does not formally describe the relationship between this supplementary service and the basic call, but where possible this information is included for guidance.<\/p>\n
In addition this ETS does not specify the requirements where the service is provided to the user via a private ISDN. This ETS does not specify the requirements for the allocation of defined Functional Entities (FEs) within a private ISDN; it does, however, define which FEs may be allocated to a private ISDN.<\/p>\n
This ETS does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.<\/p>\n
The CFU supplementary service enables a served user to have the network redirect to another user calls which are addressed to the served user’s ISDN number. The CFU supplementary service may operate on all calls, or just those associated with specified basic services. The served user’s ability to originate calls is unaffected by the CFU supplementary service. After the CFU supplementary service has been activated, calls are forwarded independent of the status of the served user.<\/p>\n
The CFU supplementary service is applicable to all circuit-switched telecommunication services.<\/p>\n
This ETS is applicable to the stage three standards for the ISDN CFU supplementary service. The term “stage three” is also defined in CCITT Recommendation 1.130 [3]. Where the text indicates the status of a requirement, i.e. as strict command or prohibition, as authorization leaving freedom, as a capability or possibility, this shall be reflected in the text of the relevant stage three standards.<\/p>\n
Furthermore, conformance to this ETS is met by conforming to the stage three standards with the field of application appropriate to the equipment being implemented. Therefore, no method of testing is provided for this ETS.<\/p>\n
