Re: Upstream channel bonding: Any plans to bond more than 2?
Nope. I am lying in bed watching star trek atm so i cant dig out all the technical gumpf for you but qam64 offers a 50% increase in throughput over qam16. I can use any arbritray numbers for the sake of example. Say you have got two qam16's doing 20mbits each, that is 40mbits for the bonded pair. If you upgrade those channels to qam64 you are looking at 30mbits each and 60 for the pair. If however you keep them at qam16 and add a further two channels then you are looking at 80mbits for the bondings group. Like i said, that is rough numbers for an example but mathematically four qam16's give you 33% higher throughput than two qam64's.
Edit: damn you seph, i just spent 5 mins typing that out on my phone :p

Moved recently and when from a 24 downstreams to 12, 2 upstreams @ qam16
Also means the most I can get here is 200, at least they let me keep gamer, hate to think what me uploading does to the neighbours.

Re: Upstream channel bonding: Any plans to bond more than 2?
Today I've seen someone on the VM forum with not four, but five bonded upstream channels!
Screenshot of their image for reference.

That's insane that would be funny if it's actually real.

I thought the SH3 was only capable of 24x4

At is simplest:
2 x QAM64 = 12 bits per thingy
4 x QAM16 = 16 bits per thingy
So 4 x 16QAM is better than 2 x 64QAM.

Ah, I see, that makes sense now. Thanks.

24x8 is what I understood as well.

Re: Upstream channel bonding: Any plans to bond more than 2?
It's certainly what the TG2492 datasheet says. 24x8.

Now on 24 down (Was on that already) and 4 up at 16 qam happened last night. Hopefully 300Mb is around the corner.

Re: Upstream channel bonding: Any plans to bond more than 2?
Sort of related to the thread, been having issues with rises in the average latency at peak times and even during the daytime sometimes. Had a thread running on the VM forum about it. http://community.virginmedia.com/t5/...n/td-p/3562884
Apparently it's down to an increase in upstream traffic but not enough to break the threshold for escalation.
Anything latency sensitive is not great when these rises occur (gaming etc.) Seeing as they don't want to do anything about it, I'm having a FTTC connection installed. It'll be slower on the download side but hopefully more consistent latency wise.
