Abstract
A telecommunications network (41) for providing telecommunication subscribers (12, 14, 16, 18, and 20) with special features independent of the subscriber's number plan includes a first switch (40.sub.1) that receives an incoming call for a dialed number subscriber. For each received call, the switch launches a first query to a first data base (Segmentation Directory 54) that identifies a particular one of a plurality of special features data bases (56.sub.1 -56.sub.x) containing call processing information for the special feature subscribed to by the subscriber. In response to the identity of the particular special features data base returned to the switch via the first query, the switch launches a second query to the identified special features data base to obtain the call processing information needed to process the call to provide the special feature. In this way, a POTS subscriber can obtain a special feature, such as time-of-day or geographic routing, for example.
