SIGNAL PROCESSOR FOR USE WITH A TELEPHONE SYSTEM AND A DIGITAL TRANSMISSION SYSTEM ABSTRACT OF THE DISCLOSURE A signal processor is provided for encoding telephone dialing signals received from a telephone system at a transmitting station and transmitted using a digital transmission system to a receiving station for decoding and application to a telephone system at the receiving station. The system includes circuitry connected to the telephone system at the transmitting station for detecting and receiving telephone dialing signals generated by the telephone system at the transmitting station. Circuitry is provided for storing the detected telephone dialing signals for a predetermined time period at the transmitting station. The system further includes circuitry interconnected between the circuitry for storing and the digital transmission system for selectively clocking this circuitry to generate digital representations of the telephone dialing signals for transmission to the receiving station. The system further includes circuitry connected to the digital transmission system at the receiving station for detecting and receiving the transmitted digital representations of the telephone dialing signals generated by the telephone system at the transmitting station and circuitry for decoding the digital representations of the telephone dialing signals at the receiving station for application to the telephone systems at the receiving station.
