ABSTRACT:
An ANI Converter System (ACS): (1) logically interfaces between: (a) a telephone network, on the one hand, and customer premises equipment (CPE), on the other hand, or (b) two portions of a switched telephone network, such as two tandem toll switching machines; (2) accepts incoming calls; (3) extracts in-band network routing and/or origination information such as ANI information; (4) uses the information to extract relevant information from a data base; and (5) places a call to a predetermined called party at, for example, a predetermined workstation to aid operators using the workstation in carrying out transactions with a calling party. The ACS includes a network signalling interface (NSI) for receiving calls from a calling party; a customer premises equipment signalling interface (CPESI) for placing calls to a called party at, for example, a business CPE; a voice and data processing means (VDPM) which is switchably interconnected to the NSI and the CPESI for detecting the in-band network routing and/or origination signals transmitted with the incoming signal from the calling party; a connection and switching means (CSM) for connecting and switching the NSI to either the VDPM or the CPESI and for connecting and switching the VDPM to the CPESI; and a controller for directing the activities of the NSI, CPESI, VDPM and CSM to accept incoming calls, to extract the in-band information, to use the information to extract relevant information from a data base, and to place a call to a predetermined called party.
