The AT&T View of Intelligent Networks (INs)

Abstract

A universal and generalized interpretation of the network intelligence is implied by American Telephone and Telegraph Company. The INs proposed here have the capacity to introduce several physical and/or logical locations of intelligence in the network. The need, level, and location for the introduced intelligence is flexible and demand-dependent. Newer technologies and services can thus be integrated in the network as they evolve. For example, the wireless and mobile radio networks can be integrated in the framework of national and international intelligent networks. In remote regions, very small aperture terminals (VSATs) interface to national networks, and their intelligence will also become desirable. Being more heavily geared toward global and national networks, the long-range survival of these networks depends upon being able to interface with many hundreds of “locally” intelligent networks. The capacity to accommodate the existing network infrastructure is one of the requirements of the newer intelligent networks.
