Intelligent network for switching broadband services

摘要

The system connects a service switching point (SSP) having a call control function (CCF), and a service switching function (SSF), to a service control point (SCP) having an intelligent service control function (SCF). The subscriber terminal (TE) is connected to the SSP via a defined interface (INAP). The interface between the SSP and the SCP is of the same type, so that the exchange of messages between these points can follow the same Intelligent Network Application Protocol, using Layer 2 of the OSI 7-layer model.
