ABSTRACT:
A data communications equipment, e.g., a modem, uses a telephone number of a remote endpoint to retrieve an associated set of stored configuration parameters. These stored configuration parameters allow the modem to quickly initialize itself and thereby significantly reduce the training interval with the remote modem. In addition, the use of the telephone number of the remote endpoint allows quick identification of modulation format, e.g., that a fax call is being established.
