<p>In a network-based telephone system [100] including a service control point (SCP) [102] for accessing a call processing record (CPR), an intelligent peripheral (IP) [104] provides an intelligent interface between a caller and the SCP [102]. The IP [104] communicates with the SCP [102] through a peripheral interface (PI) [128]. External systems [106] are accessed by SCP [102] through a generic data interface (GDI) [124] to obtain customer data. The GDI [124] keeps track of the data stored in the various external systems [106]. Upon receiving a request for data, GDI [124] forms sub-requests, routes the sub-requests to the appropriate external systems [106], and returns a message containing the requested data.</p> |
