摘要：
A duplex modem for processing data needed for cancelling far-end echo includes at least one high-speed processor of the data pump type performing filtering operations and a microcontroller. The data, corresponding to transmitted data and necessary for cancelling far-end echoes, are stored in a memory associated with and controlled by the microcontroller.
