Abstract

Defines the stage two of the Multiple Subscriber Number (MSN) 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 this supplementary service and basic call, but this information (where possible) is included for guidance. Also, does not specify the requirements where the service is provided to the user via a private ISDN. Defines which functional entities may be allocated to a private ISDN, but does not specify the requirements for the allocation of defined functional entities within a private ISDN.
