1. A method using a communications device to interface a plain old telephone system (POTS) terminal, which includes a dial-up modem to transmit data, to a communications network, including:

  • initiating a communications host session between the communications device and a communications host, prior to locally generating a connect sequence;

    locally generating a connect sequence between a POTS terminal and a communications device, whereby the communications device appears to the POTS terminal to be a modem accessed via a telephone network;

    locally decoding and encoding communications with the POTS terminal, including recovering digital data from a modem carrier signal received from the POTS terminal; and

    conducting a packet-based session between the communications device and an application host through the communications host using the recovered digital data.
