Abstract
Abstract An intelligent call processing system is arranged so that each originating switch is provided with a local database called a "global title translation (GTT)" database, which receives a query fully identifying the calling station, typically in terms of its 10 digit number (i.e., three digit [NPA] area code, three digit [NXX] exchange, and four digit line identification). The GTT database responds to the query by identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call. If the GTT database does not contain an entry, or an error condition exists, a further query is launched to a centralized database, called a "universal global translation (UGT)" database. The UGT database then retrieves information identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call, and provides this information to the originating switch. The same information may also be provided to and stored in the GTT database, so that the GTT database is "self provisioning".
