An enabling technique for quickly establishing high speed PSTN connections in telecommuting applications

摘要

A data communications equipment, e.g., a modem (100;200), uses a telephone number of a remote endpoint (50;60) to retrieve an associated set of stored configuration parameters. These stored configuration parameters allow the modem (100;200) to quickly initialize itself and thereby significantly reduce the training interval with the remote modem (200;100). 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.
