Abstract:
Disclosed herein is a multi-stage echo cancelation scheme. The disclosed embodiments include an apparatus and method for monitoring and canceling echoes greater than 25 dB in a coaxial cable plant. The method includes obtaining echo channel estimate coefficients from a cable node. The method determines a location and strength of each partial echo in an impulse response using the echo channel estimate coefficients. Optionally, the method determines a frequency response of each partial echo in the impulse response.

Claim (Index 13):
The echo canceler of  claim 10 , further comprising a digital-to-analog converter coupled between the first echo canceler and the first subtractor, the digital-to-analog converter configured to convert the first cancelation signal to a digital signal.
