The core idea of this invention is that functionality is added to modems which allows them to periodically renegotiate to try to attain a higher data rate using a background process and a secondary phone line. The modem sends its identification to the Service Provider (SP) whenever a session is established. If the modem connects again on a different phone line, the SP is now capable of transferring the session already established to the second phone line, and the first connection is dropped after the transfer. During the negotiation phase, the SP informs the modem how often to attempt a new connection, and the phone number at which the connection should be attempted.
