An adaptive analog echo/near-end crosstalk (NEXT) cancellation system includes a selector that outputs a first error control signal when a first receive signal does not include a remotely transmitted signal and a second error control signal when the first receive signal includes a remotely transmitted signal. An echo/NEXT cancellation module communicates with the selector and generates an estimated echo/NEXT signal based on the first error control signal and a first transmit signal when the first receive signal does not include a remotely transmitted signal and based on the second error control signal and the first transmit signal when the first receive signal includes a remotely transmitted signal. A summing module receives the first receive signal and the estimated echo/NEXT signal and generates an echo/NEXT filtered receive signal by subtracting the estimated echo/NEXT signal from the first receive signal.
