Abstract: A network device has a communications port to provide communication with a data network and a cable port to provide communication with a cable network across multiple channels. The network device also has a processor to receive data from the data network, format the data into packets for transmission across the multiple channels and provide an identifier to allow the packets to be reconstructed.

Abstract: A hybrid cable modem includes wideband circuitry configured to receive data over multiple different downstream channels at the same time. The wideband circuitry demodulates signals on the different downstream channels and then formats the demodulated signals back into packets or frames for sending out over an Internet Protocol (IP) home network. Narrowband cable modem circuitry is coupled to the wideband circuitry and selectively extracts Data Over Cable Service Interface Specifications (DOCSIS) data from one of the multiple downstream channels being processed by the wideband circuitry.
