Abstract
Disclosed herein are techniques for bidirectional communication in a network, such as a cable television (CATV) system, for return band with echo cancellation. The techniques result in a minimum loss of available return bandwidth to facilitate forward out of band (OOB) communication to a client device, e.g., set top box (STB), within the extended return band, such as a return band extended beyond a frequency previously used for OOB communications.
