Regardless the CPE and standards support a far better practical upstream ratio than the predecessors.

Only the current generation of 8 down 4 up D3 CPEs. Wasn't the VMNG300 theoretically 4 down 4 up, and DOCSIS 2 and before were all 1 down 1 up anyway.

It's a non-issue though as VM aren't going to be deploying a DOCSIS 3.1 product imminently, there's plenty of life left in DOCSIS 3.0.

Didn't we establish VM were going to start deploying D3.1 early next year?

Wasn't the theoretical 8/8 with a firmware update?

General Maximus · 08-01-2015, 18:54

no, it was 8/4 and VM ran out of contract with the manufacturer so they couldn't get the new firmware made. The vmng300 would have been a cracking modem if it could load balance across 8 channels.

Between me and everyone else to ever visit this site. 400mb d/l will be the next big step

and uploads will be increased by a huge amount

You think cable companies have that much unused downstream capacity lying around ready to be used pretty much straight away?

Finding another 64MHz for this year's upgrades was a non-trivial task. Some areas are going to need, and will receive, plant upgrade to go further. Part of this upgrade is 85MHz mid-range upstream with a relatively easy upgrade to full DOCSIS 3.1 range via diplexer swap.

If dealing with VM:

I mentioned specifically practical ratio and chose my words carefully on that one. EuroDOCSIS 1/1.1 you were dealing with 50Mb downstream, 10.24Mb upstream channels, usually at a ratio of 1:4 or 1:3 making offering anything like symmetry extremely unwise as channels degraded at c.70% utilisation and upstream usage was way more constant than downstream.

EuroDOCSIS 2.0 is a different animal but still maximum upstream bandwidth 27Mb with same restrictions on channel degradation hence perhaps 20Mb usable at most. The highest service tier I've seen on DOCSIS 2 was 10Mb.

Statistical contention has left more options and this effect on 3.1 will be even more pronounced.

Did we? Liberty Global doesn't mean VM by default. This tech is more likely to be deployed where a Liberty Global company is in competition with FTTP or where a hardware refresh is due.

The plans for the next couple of years at least are focused around DOCSIS 3.0. Subject to change of course.

VM are deploying new kit, some of which is DOCSIS 3.1 ready, however 3.0 supplies what is needed for a while. It's not like Openreach are pushing hard with their 80Mb/20Mb FTTC product - VM will be offering the same or better than anything Openreach offer in consumer grade services anywhere in their footprint by the end of the year.

You were the one who explained to me that's what Pierre was trying to say...

I can only go off the documentation I have seen, I'm not in the Access dept so not close to it.

But from what I have seen last year, DOCSIS 3.1 deployment is scheduled to start in Q2 next year, with a further upgrade planned in Q3 2017. The network is planned to be 600Mb ready by end 2016/2017.

There's a whole host of other stuff to be looked at as well CCAP, EPoC running DOCSIS 3.0 and 3.1 together and other stuff that is outside of my area of expertise

OF course 10Gb is not going to be offered, why would it. It's theoretical. The main thrust of the article is that VM is moving to Docisis 3.1. and from what I've seen it will be well before 2020 - I don't know where you get that from.

No, quite the opposite. The fact that it will be restricted to the current spectrum until major network upgrades are done means it will not offer a huge change in available ratios.

What's your source or is it a guess?

Without a source we must presume it is a guess.

Kushan · 09-01-2015, 09:18

Or a complete fib.

Anything's possible Kush.

Exactamundo. We've had some pretty authoritative information from those who do know.

Can't really say much about this part as probably TMI, beyond that I suspect Pierre was referring to DOCSIS 3.1-ready equipment along with 'other' upgrades. The plans as they stand are for deployment of more DOCSIS 3.0 downstreams and this has kicked off already, with 600Mb-ready network coming via more of the same.

That ignores a number of issues preventing more efficient use of the current spectrum. VM's upstream ratios are not due to a lack of upstream split.

As far as VM go though it's not really an issue. There won't be a DOCSIS 3.1 transition for a while yet. Kit is going in that is ready for it but plans still focus around DOCSIS 3.0, not to mention that major network upgrades start soon per comments in the thread about massive network upgrades

A guy making a first post on the forum predicting a near-tripling of VM's speeds downstream and huge increases upstream?

Clearly legit.

VM have no need to go ridiculous, they're already #1 in 95% of their covered areas.

Or it could be a very knowledgable existing member registering a new alias so that the 'leak' couldn't be traced to him

They were already #1 in most of their covered areas before they decided to 'go ridiculous' and double BT's headline speed. Clearly 152 was a direct shot at BT/FTTC, so who knows, VM 400 may be a shot at BT's last remaining stronghold, 330Mbps FTTP.

100Mb -> 120Mb -> 152Mb was relatively easy. 300Mb / 400Mb not so much.

I'd best pass this on to the guys planning the additional capacity for this year's upgrades with the note that they need to find another ~33%.
