Claim 19:
20. A communication network node, comprising:
a first digital-to-analog (D-A) converter configured to convert a first digital signal to a first analog signal;
a splitter configured to output the first analog signal to an analog network for transmission to a recipient;
an equalizer configured to generate a second digital signal based on an echo expected in response to transmission of the first analog signal from the communication network node;
a second D-A converter configured to convert the second digital signal to an analog cancellation signal; and
a combiner configured to generate a second analog signal by combining the analog cancellation signal with a reflection received at the splitter following transmission of the first analog signal therefrom.
