The C10G supports complete separation of downstream (DS) channel capacity and upstream (US) channel capacity in a single physical chassis, providing a flexible downstream to upstream channel ratio. Cable operators can add downstream channels and upstream channels completely independently within the same chassis.

The DOCSIS QAM Module (DQM) is a complete DOCSIS downstream unit that includes DOCSIS packet processing, QoS, DOCSIS downstream MAC, PHY and RF up-conversion.
