Abstract
A cable modem comprises transceiver circuitry and echo cancellation training circuitry. The transceiver circuitry may be operable to transmit and receive signals on a full-duplex Data Over Cable System Interface Specification (DOCSIS®) network. The echo cancellation training circuitry may be operable to: determine an echo cancellation training group to which the electronic communication device belongs; determine one or more training periods during which the echo cancellation training group is permitted to transmit training signals; and transmit an echo cancellation training signal during the determined training one or more periods and use the transmitted training signal to train echo cancellation circuitry of the cable modem.
