The purpose of the Intelligent Network is to ease the introduction of new services in the public switched telephone network. The IN tools dedicated to service creation, prototyping and modification, are an essential asset to network operators since they enable saving time and money when specifying a new service and by allowing service software to be developed and to evolve in a user-friendly environment. By integrating data processing and telecommunication development tools, original solutions can be put forward to satisfy new needs in software development. The underlying goal of the Alcatel solution described here is to offer the same working methods to satisfy any of the multiple aspects related to network service development.
