Abstract: In a cable television system a system for supporting SCU return in FTTB-MDU and FTTC/FTTcab configurations. Fiber, baseband transceiver and networking capabilities are shared with data and voice portions of the system for enabling communication from the SCUs to the HE over a packet based networking system. Return packets/upstream packets are passed into the network upstream channel only when a signal is present for eliminating transmission of upstream traffic that contains no signal for conserving upstream bandwidth.
