Abstract:
1. A Digital Simultaneous Voice/Data (DSVD) endpoint, comprising: a data port interface for coupling to an access server or telephony gateway for generating an Internet Protocol (IP) voice packet to transmit to a telephone having an IP address corresponding to the IP voice packet and an IP data packet to transmit to a computer having an IP address corresponding to the IP data packet via an Internet network and configured to transmit and receive both the voice packets and the data packets; a circuit switched interface for coupling to a circuit switched network; a modem configured to receive and transmit a Digital Simultaneous Voice/Data (DSVD) data stream containing DSVD multiplexed voice and digital data from a remote DSVD endpoint; and a framer and interleaver configured to interleave the voice and data packets together, and add DSVD madam framing to the interleaved voice and data packets; the framer and interleaver further configured to remove DSVD modem framing from the DSVD multiplexed voice and digital data received over the circuit switched interface and transmit both the voice and digital data over the data port interface over the Internet network to the access server or telephony gateway; the DSVD endpoint not compressing or decompressing the voice data contained in the DSVD data stream or the voice packets transmitted between the remote DSVD endpoint and the access server or telephony gateway and deriving the IP addresses corresponding to the IP voice packet and the IP data packet using only the DSVD data stream.
