Abstract
Many multinational companies have successfully used intelligent network services within a country to control costs and, at the same time, enhance network management control and feature functionality. As intelligent network services continue to evolve and prove their value on a national level, and as customers expand internationally, there is a natural demand to extend these telecommunications capabilities globally. This paper highlights issues that must be considered as we design and implement global intelligent network services. It also includes either a high-level or a conceptual view of four potential global intelligent network services: global virtual private network, global credit card validation, global Freephone, and global switched digital data.
