Abstract

Current integrated services digital networks (ISDN) can provide subscribers with access to the Internet and can support variable data rate connections between Internet switching nodes. This paper describes how ISDN and the Internet can be further integrated and communication capabilities improved by expanding the role of ISDN switching centers to include certain packet switching functions. Enhancements are identified that allow narrowband ISDN (N-ISDN) to support full motion video in addition to voice and data communications. These enhancements, along with the further integration of ISDN and the Internet, would facilitate a smooth transition from N-ISDN to broadband (B-ISDN).
