Abstract
Abstract A system and apparatus for enabling modems having incompatible modulation methods to communicate with one another. The adaptive modulation system is adapted to enable a first communications device having a first modulation method to communicate with a second communications device having a second modulation method, even in those instances where the modulation methods are incompatible. The adaptive modulation system includes a communications device having a controller, a data pump and a data access arrangement/coder/decoder. The controller further includes an adaptive modulation unit having a decoder/interpreter, and a programmer. The decoder/interpreter in the adaptive modulation unit in the first communications device receives an incompatible modulation mode algorithm from the second communications device. The programmer receives the decoded modulation algorithm and programs the flash ROM with the new modulation method. A comparator may also be used to determine whether transfer of the algorithm is time efficient.
