A physical or virtual node within the inteligent network, the Service Control Point (SCP) contains the active database of customer records. This database is actively queried from either the Service Switching Points (SSPs) or Service Platform Trigger Points (STPs) within the network to seek and obtain service-completion information. The SCP queries the service data point (SDP) which holds the actual database and directory. SCP, using the database from the SDP, identifies the geographical number to which the call is to be routed. This is the same mechanism that is used to route 800 numbers.
