AbstractThe development of telecommunications technology and the need for more advanced services has created projects on standardization of international Intelligent Networks (IN). The standards of Intelligent Networks define IN in an abstract point of view, so it leaves the service providers the decisions on their own implementations. The first standard sets of IN are Bellcores AIN.0 and the CCITTs Capability Set 1 (CS1). They define the basic services of IN, additional features such as rapid service introduction and a flexible architecture that provides future expansion to further IN Capability Sets. The standardization organisations, such as CCITT and ETSI, work hard to help the service providers to implement their IN architecture in order to be able to provide international IN services. This kind of architecture is better known as Global Intelligent Network architecture and it should be taken into consideration already in the early implementations of IN. This paper presents some history of telecommunications technology, an overview of IN and its services and some additional discussion on the future broadband IN.
