SYSTEM AND METHOD FOR USER INFORMATION TRANSFER BEFORE MODEM CONNECTION

摘要

A system and method for user information transfer before modem connection. The invention makes high-speed modems more efficient, particularly for transaction and Internet applications, by providing for transmission of pre-connection user data during modem training. A training sequence for a modem in accordance with the invention may be summarized as follows: beginning training of the modem at a first data rate using a defined training sequence; after a selected amount of training, transmitting pre-connection user data from the modem at up to the first data rate while continuing training of the modem; ending training; and enabling transmission of user data at a full connected data rate of the modem. The invention may also include the following training sequence before enabling transmission of user data at the full connected data rate of the modem: beginning secondary training of the modem at a second data rate using a defined training sequence; after a selected amount of secondary training, transmitting pre-connection user data from the modem at up to the second data rate while continuing secondary training of the modem; and ending secondary training.
