Abstract

In a communications system containing signal enhancement circuitry capable of selectively enhancing portions of a plurality of signals carried on a corresponding plurality of channels through the signal enhancement circuitry, a system and method for controlling enhancement on a per call basis. The system includes: (1) command generation circuitry for generating an enhancement command for transmission to the signal enhancement circuitry and (2) command reception circuitry, associated with the signal enhancement circuitry, for receiving the enhancement command from the command generation circuitry and selectively enhancing the portion of the signals on the per call basis according to the enhancement command.
