Thanks for clarifying. I can't imagine an MSO using separate DS and US QAMs for their eMTAs. Regardless, the customer's Internet would flow over those same QAMs (unless it was a D3 channel-bonding eMTA, and even then I'm not sure if the CMTS could be provisioned to use one QAM for voice and the remaining QAMs for data).

Frank, No, not all. There seems to be some confusion here between the concept of PacketCable flows which everyone _should_ (but aren't) be using to prioritize their voice traffic and separate downstream and upstream channels which a few operators use for voice traffic only.
