said by tmc8080:They could offer those speeds, but not at the current forward combining they have setup today.. They will more than likely reduce the number of users per downstream QAM , which in some cases means doing node splits. As far as uploading they will need to be at 1:1 per uBr upstream port.
Why even upgrade if the speeds are going to be in the 20-50 megabit range? This could be done NOW without docsis 3.0
A fully uncapped docsis 2.0 speed would do this already without ANY upgrades. Only areas with docsis 1.0/1.1 should be upgraded to docsis 3.0
