Abstract

A telephone system simultaneously transmits voice and data through a public switched telephone network and over one telephone line between a calling party location having an ISDN connection and a destination party location having a POTS analog connection. The calling party location determines if the destination party location has an analog POTS connection and then creates a connection between the calling party and the destination party. Data and voice band signals are packetized and multiplexed and transmitted through the public switched telephone network to a modem located at the destination party location. The packets are demultiplexed into separate voice band and digital signal components and the digital signal components demodulated within the modem. The demodulated data signals are forwarded to a data terminal and a voice band signals forwarded to an analog terminal.
