Abstract
In conjunction with elements of a single conventional telephone, a central processor isolates the telephone from the communications network facility to function with a voice synthesizer structure and a DTMF encoder/decoder apparatus and develop a data packet for inquiry from a terminal to a telephone inquiry processing center. On completion of the data packet, a dial-up connection is established between the terminal and the inquiry processing center for fast, efficient automated communication. Reply data is delivered through the telephone by the voice synthesizer. The control processor executes a series of switching operations to accomplish the data exchange.
