Abstract
A multi-media modem is used to provide a security access arrangement that identifies a calling party to a computer system. In particular, a multi-media modem couples both an analog channel and a data channel to the computer system. The analog channel conveys the calling party's identification information, while the data channel conveys a data signal from the calling party. The computer system verifies the calling party's identification information communicated over the analog channel and, if the verification is successful, immediately establishes, or continues, data communications with the calling party over the data channel.
