ABSTRACT:
A telecommunication network includes a first telecommunication switch that supports subscribers coupled to the first switch and recognizes a request for call origination by a calling party on an associated communication line. The request for call origination services seeks services from a second switch. A first record in a database coupled to the second switch is located based on the identification of the calling party's line. The second switch is disposed at a hierarchical level above the first switch. A first set of predetermined features is determined based on information contained in the first record. A personal identification number of the calling party is received at the second switch. A second record in a database is located based upon the PIN; the second record is independent from the first record. A second set of predetermined features is determined based upon information contained in the second record. The set of features made available to the calling party from the second switch is determined based on a consideration of the total set of call features in the first and second sets of features.
