Think you don't understand what DOCSIS 3 is. DOCSIS 3 is a method for channel bonding multiple RF streams. At the RF level DOCSIS 3 downstreams on the VM network are EuroDOCSIS, and for now the upstreams are using standard DOCSIS 1 / 1.1.
The entire network does not migrate to DOCSIS 3 nor is it more efficient, you simply have a larger single data pipe, consisting of 4 bonded 8MHz channels, so can offer a single 200Mbit channel to a node instead of the previous 51Mbit per channel. It means higher data rates possible and better statistical contention as each modem takes less of each
logical channel.
