Integrated Services Digital Network (ISDN); Freephone (FPH) supplementary service Service description

Scope

This standard defines the stage one of the Freephone (FPH) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications operators. Stage one is an overall service description from the user's point of view (see CCITT Recommendation I.130 [1]), but does not deal with the details of the human interface itself. This standard defines the interworking requirements of private ISDNs with the public ISDN. In addition this standard specifies the base functionality where FPH supplementary service is provided to the user via a private ISDN.
