A vmng300 modem wont automatically get less speed in 8 DS channel service groups, in fact its more likely to get higher speeds as there is more capacity available to all users.

Yet if one of the VMNG300's in each of the 4 DS channels take 120Mb then the other VMNG300 in your example can only achieve the remaining 80Mb. So only half the VMNG300's achieve full speed. i.e. two modems.

Compare that with 8 DS channels where 3 Superhubs can achieve the full 120Mb with a remaining 40Mb left over.

If you mix VMNG300's into already saturated channels then the situation can be even worse where none of them achieve full speed.

Although thats an unlikely situation

And superhubs on saturated channels can magically add their own bandwidth!?

It doesn't matter how unlikely a situation it is. Less VMNG300's will achieve full speed than Superhub's given a finite set of channels, no matter how large that number is.

That's a strawman argument and you know it.

With the 120Mbit config set at 133Mbit, that leaves 1Mbit of shared capacity left over, although, again, not a likely situation, and will also vary area by area see here for a simple explanation of bandwidth contention, its not something that can be plotted, or have rules applied to it, it varies area by area, and VM have to manage it as so

Not sure whats so complex about it.

A docsis will assign 4 DS channels to a connecting vmng300, unless there is a fault or restriction in config. If there is more than 4 DS channels the docsis can choose which 4 to assign, it doesnt have to be the same 4 every time, so as such a degree of load balancing can still occur with 4 DS modems on 8 DS channels. Indeed VM have operated like that for years prior to docsis 3 eg. using 1 US channel modems in service groups of 4 US channels.

A vmng300 modem wont automatically get less speed in 8 DS channel service groups, in fact its more likely to get higher speeds as there is more capacity available to all users.

The sh2 a fine device which completely obseletes the vmng300? never used a sh2 so cant speak on own experience but there is problems reported by sh2 users so I expect the statement is false.

Whats that got to do with it, as you even mentioned above EURODOCSIS channels have more bandwidth so the 38mbit per channel on that link is irrelevant

38 meg is what a 6MHz channel bandwidth delivers (to put it another way).

To those who wonder if their broadband ONLY package will see a price increase from 1st February 2014.

In my case I can CONFIRM YES it will.

Have just received letter. It will go up by 3.25 GBP for me. So will be 38.25GBP per month.

My Package is: XXL120 BB ONLY
