scope:
This standard defines the stage one of the User-to-User Signalling (UUS) 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.
