Intelligent Networks/1+ (IN/1+)

Abstract

The Regional Bell Operating Companies (RBOCs), in conjunction with the research done at Bell Communications Research (Bellcore), have proposed the IN/1+ concept and its architecture in considerable detail to circumvent the limitations of IN/1. The IN/1+ architecture and phased introduction is planned to be realized in the United States during the early 1990s. The phased introduction of IN/1+ is to facilitate the gradual merging of the intelligent networks (INs) in the switching and transmission environment with the introduction of newer digital services associated with ISDN and ISDN-like services in the public arena. Considerable coordination between the capabilities of the intelligent networks (IN/1+, IN/2, etc.) and existing telecommunication networks will be required as the new networks are introduced. The demand for such intelligent services proposed by IN/1+ and IN/2 is still to be substantiated in society. Simultaneously, newer digital services, such as ISDN, global message, and packet switching, will be introduced and become available if they are accepted by the business community and by the public.
