Integrated Services Digital Network (ISDN); Interworking between public ISDNs and private ISDNs for the provision of telecommunication services; General aspects

Scope

This standard describes general requirements on standards for services with respect to interworking between public Integrated Services Digital Networks (ISDNs) and private ISDNs. This standard describes the different mechanisms whereby services implemented by public ISDNs can be provided to users attached to private ISDNs. Service specific information on the interworking between public ISDNs and private ISDNs is given in the various standards for the individual bearer services, teleservices and supplementary services. In addition, this standard identifies the need for general procedures in the public ISDN required to support the transport of information given to other users as a result of the operation of services in the private ISDN. Consideration of regulatory requirements placed on public ISDNs and/or private ISDNs is outside the scope of this standard.
