History

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.

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.
