Tell me which of these Virgin Hubs did NOT have modem mode? SH1, SH2, SH2ac, Hub3? I rest my case.

But their was a hub before SH1 that did not have modem mode the VMDG280.

Indeed I can. What did you want to know?

Pilot deployments this year then means public trials in September/November?

Any hint which hub they're going to use?

[CarlTSpeak]

Back end of the year and no idea respectively.

With regards to CPE whatever will be cheapest I imagine. After the farce with the Puma 6-based Arris this will likely be an Arris-built Puma 7-based piece of kit. Should be able to secure some nice discounts in recompense for the embarrassment and grief it's caused Liberty Global.

They may go for quality but I'm not aware of either VM or Liberty having any kind of form for spending more on better CPE.

Actually the SB8200 that Comcast are supplying retail didn't have modem mode in the firmware back in January. It's being worked on. Not always good to get products too early. The Hitron also didn't have modem mode when it came out but now does. So while it's a possibility, it depends on the timing. It'll definitely be a requirement though.

No chance of us getting the SB8200 anyway, it's $160 retail and Liberty and VM buy around $50.

In places there are nodes with all 24 channels lit, I should make clear that the current VM platform can't deliver more than 24 channels in a single group so they can't spin up 32 and load balance, that are still experiencing capacity issues or will be in the not too distant. Selective deployment of 3.1 is a viable capacity relief option for these and will relieve the need for node splits.

Yeah well Comcast are doing 16 x SC-QAM channels + 1 OFDM channel.

Longer term VM do have to pursue a strategy of adding more 3.0 channels in areas that aren't maxed out, delivering 3.1 to relieve 3.0 of the heavier users, splitting nodes and upgrading HFC plant where there are RF capacity issues preventing addition of more 3.0 channels and a 3.1 OFDM block. Those are presented in order of cost.

Agreed.

There are some issues that I won't go into in public with regards to capacity planning. Liberty Global need to get their heads around that one size does not fit all and UK and Ireland customers have usage patterns and expectations that don't match those in Hungary or Romania.

Yeah I can imagine.

[CarlTSpeak]

Comcast run with way more than 16 SC-QAMs. They've 24+ running in many places alongside 4 x 6.4 MHz wide upstreams crammed into the low split 5-42 MHz band.

They sell an 'Extreme' 300Mb tier. Selling that on 38 x 16 = 608 Mb of capacity is 'risky' given how intolerant the United States consumers are to visible contention and requires very small nodal areas.

See https://www.dslreports.com/forum/r29743167-Signals-Report-16-24-32-Downstream-Channel-Bonding-Here

Regarding VM's capacity issues there are problems both at hubsites and in some cases the access plant preventing addition of extra channels and problems preventing node splits.

I've had more than a few drinks so am likely more amenable to requests for information I'd usually decline. What would you like to know?

If it's the meaning of life: 42.

Will I like this hub 4?and be part of the trial for it?

No idea and hopefully not. Any issues you'll put down to whatever you've googled and are fixating on as you very clearly don't have any quality experience in the field thus obfuscating any investigation into any genuine issues.

Like SH2ac in router mode DHCP bug is not a bug its intended to cause what looks like a fault one of the reasons its not fixed.
