Abstract
In a packet data communications system () where a customer premises () has only a packet-based connection, a proxy modem () is provided at the customer premises to connect to devices that send and receive modulated transmissions, e.g., facsimile, modem, and TDD/TTY. The proxy modem demodulates the modulated transmissions (), organizes the resulting digital signal into a packet () and forwards the packet over a packet network (). Another proxy modem () that connects to the packet network and to a telephony network () receives the packets from the packet network. The packets are re-organized into a digital signal that is then modulated and forwarded over the telephony network to a destination. Use of the proxy modems in the network prevents unnecessary digitizing of modulated transmissions, which slows transmission and introduces errors.
