Intelligent Network (IN)

Intelligent Network (IN) allows functionality to be distributed flexibly at a variety of nodes on and off the network and allows the architecture to be modified to control the services. These networks can separate extra services from the call switching system, making it easier to add new user services.

By using additional technology, such as a Service Control Point (SCP) and a Service Management System (SMS), these advanced networks can accommodate services like call screening or call waiting, as well as more complex services like variable charging, caller ID services and international messaging.
