i found the slides , my mistake they were more for the downstream and they only show the US 6MHz not the Euro 8MHz etc but take a look at slide 25 and 26 for an idea.

btw, heres the info for those current D2 cards with masses of extra ports per card.
and it seems they are or will be ready with D2.0
B specs and so usable with the far better speeds on a single channel, and they are still the cheapest any cards have been to date too...

shame about him canning the core 100Gig tested though as per above to cure or at least mitigate many near future potential problems.... (shhh, dont mention the 50Mbit will be really 43 Mbit
max before any STM is even used due to the stupid 1.5Mbit limit on the upload ).
so NOT 2010/1012 after all, infact its this month........

Analogue axe 'could lead to 100Mbps net'

Turning off analogue signals will allow Virgin Media to provide 100Mbps downstream speeds over its cable network "
if we chose", according to the firm's chief executive.
Neil Berkett said the combined effects of introducing the DOCSIS 3.0 transmission standard
and the freeing up of capacity by switching off analogue cable TV transmissions would allow it to continue providing faster broadband than competitors.
The company today confirmed it was commencing a
tentative region-by-region programme of ending analogue cable TV service.
"Relatively modest investment in customer equipment and [headend] ports for channel bonding is required to do this and
is included in our current capital expenditure guidance,"
he told investors.

Virgin begins analogue cable switch off
Monday, May 12 2008, 12:35 BST

Virgin Media
has begun a tentative programme of
switching off analogue transmission across its cable network.
Digital services have been available across much of the UK's cable network for several years, but about
200,000 homes are still watching analogue cable television provided by Virgin.
Under the "long term" region-by-region project,
which is beginning this month, analogue subscribers in areas where digital cable services are already available will be offered transfers to new packages, the company told
Digital Spy.

any comments on how this switch off might effect the (Baguley ?..NW) bringing the "return path up to a higher quality" and so presumably improve the noise levels and far better Euro-D2/D3 (single channel) freq use throughput etc.....

"Berkett said: "We currently only use two 8Mhz channels to serve all our broadband customers. For DOCSIS 3.0 this will be tripled. Each additional channel will be freed up by switching off a single analogue channel.

keep in mind they dont have silver or "full" for this CMTS kit yet but this press release just now was interesting for the
first real officially stated MAX No.s for the minimum spec 4 ports download speeds.
not that we will see anywere near this with VM limits in place inthe future, but the potentials there.
see the TX32 card i referenced on the other thread for the up/down ports etc...

The BSR 64000 can be configured for I-CMTS with the addition of the
Motorola TX32 decoupled downstream module.
The deployment of the TX32 provides a significant increase in downstream capacity and an increase in downstream bandwidth.
It allows operators to deploy ultra-broadband services with data speeds in excess of 145 Mbps to a single DOCSIS 3.0 cable modem, and over
200 Mbps to a single EuroDOCSIS cable modem, by leveraging DOCSIS 3.0 downstream channel bonding....
