A full-duplex communication device includes a transmit channel, a receive channel, and echo cancellers connected between the transmit channel and the receive channel. A plurality of control parameters and status indicators are defined for both channels. The plurality of control parameters are accessed via a writable interface for controlling operations of the communication device. Typically the control parameters are modified, enabled, and disabled based on an implemented control method and based on signal conditions, including noise, echo, tone, and other abnormal noise conditions. A writable access port enables a user to request tweaking, modification, enabling, and disabling of multiple features and controls. A readable/writable access port enables access to multiple status parameters that are indicative of the status of the communication device and channel operating conditions.
