History

Defines the stage two of the Subaddressing (SUB) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as given by European public telecommunications operators. Does not formally describe the relationship between the basic call and this supplementary service; the information (where possible) is included for guidance. Defines which functional entities may be allocated to a private ISDN; does not specify the requirements for the allocation of defined functional entities within a private ISDN. Does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.
