An example application of the intelligent network conceptual model in the LAN environment

The paper presents the design and implementation of an experimental set of supplementary services over a conversational talk service in a local area network (LAN) environment, applying the principles of an intelligent structured network. The International Telecommunication Union (ITU) Intelligent Network Conceptual Model was applied as a formal framework. Special emphasis was put on the service functional modules, their decomposition on the different levels of abstraction, and the logic of their interconnection. The tools and models used in the detailed specification are referenced. The supporting intelligent local network application protocol was specified and a distributed software application was developed and implemented in the department's local network. Remote procedure call protocol software was used as an application programming interface.
