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.
