Abstract
A method and apparatus for achieving the fastest possible data transmission rate, symmetric, near symmetric, or a specific data transmission rate between multiple analog modems. The invention comprises a multimedia unit comprising of two (or more) digital modems and a controller section. The controller provides the interface between the two (or more) digital modems. When a user attempts to send data from a first analog modem to a second analog modem, the user calls the first digital modem in the network. Next, the first digital modem establishes a connection with the second digital modem through the controller section which is partitioned in two segments. Controller segments may be co-located or located in different locations and connected through either Internet or PSTN. Then, the second digital modem dials up the second analog modem under direction of the controller. Subsequently, the controller commands the digital modems to establish a connection at the fastest possible symmetric rate, near-symmetric, or any other pre-configured rate. Last, the controller bridges traffic between the digital modems and enables the two analog modems to communicate transparently.
