What you evidently don't know is that most of a legacy CMTS is being moved onto each 50Mbit MAC domain - In my CMTS's case if you were to move 75% of the customers across, not an uncommon combining apparently, you are dealing with 300 20Mbit modems on 2 8.8Mbit upstream and 3 51Mbit upstreams, not including the 50Mbit customers with no STM.

Presently the loading is around 100 modems of all tiers to an upstream, so you can see why a big uptake of 50Mbit with its' un-STM'd bandwidth restrictions might be problematic.

Any further questions have a check on your tools or log directly onto a 10k / BSR for how many nodes a single 50Mbit downstream group is spread across relative to a standard downstream.
uve stated here that 20mb users will be using Docsis 3.0, ive spoken to u about this before on other posts and u have stated that this is not the case they will be using only docsis 2.0. If the 20mb users are to use and get the full affect of docsis 3.0 surely Virgin would have to replace the modems of the 20mb users to docsis 3.0 compatible ones.
