Abstract
A system and method for communicating with a cable modem having an RF interface for downstream data and a PSTN interface for upstream data. The system uses a cable modem driver that receives commands for sending and receiving data. The cable modem driver interfaces to the RF interface to receive downstream data. The cable modem driver interfaces to an inner protocol driver to redirect data to a standard modem driver. The inner protocol driver sends the data to the modem driver and the modem driver sends the data over the PSTN connection.
