<p>A telecommunications system, has an intelligent network architecture and includes service data points, service control points, and a plurality of service switching points. Functional entities, e.g. Internet servers, service data points, service control points, service nodes, intelligent peripherals, and Internet support systems control the execution of telecommunications services and are linked by a data transmission network, capable of operating independently of the main telecommunications traffic network. The telecommunications system is arranged in three hierarchical levels, namely: a service execution level; a service switching level; and a switching and transport level. The data transmission network may include several LANs, to which the functional entities used to execute telecommunications services are connected.</p> |
