Uddingston upstream 3 channels?
 

Has this been around for a while or is this just new?.. First time i've seen a 32QAM upstream.

Screenshot attached from status page.

Re: Uddingston upstream 3 channels?
 

Is this for the increase upload speed rollout?

Re: Uddingston upstream 3 channels?
 

No idea im currently on 152/12

Re: Uddingston upstream 3 channels?
 

So are you in the Hamilton area as I was on that UBR about 4 years ago

Re: Uddingston upstream 3 channels?
 

No mate.

Re: Uddingston upstream 3 channels?
 

Let's hope they keep rolling this out, Can you post the Network Log for the modem to see if we can tell when the upgrade happen Ps. remove ip from the log before posting m8 Thank you. :)

Re: Uddingston upstream 3 channels?
 

attached.

Re: Uddingston upstream 3 channels?
 

You are the best thank you for posting the log info. :) It looks like it may have been enabled on the 7th

Re: Uddingston upstream 3 channels?
 

Restarted Hub and all channels are now 64QAM. as apposed to one 32QAM in the previous screen.

Re: Uddingston upstream 3 channels?
 

Interesting you've got 3 upstream channels, but I think the 32QAM was was an irregularity and it should have been 64QAM.

Either way, this is all good stuff as it's a large increase in available bandwidth.

Re: Uddingston upstream 3 channels?
 

Splendid. The upgrades on the upstream side, to go along with the downstream that have been a work in progress for a little while, have begun :)

Re: Uddingston upstream 3 channels?
 

Very interesting. I just had another look at mine to see if I was on 3 upstreams yet and when I looked at my log I noticed a new config had dropped down on Friday. Last week I was on r29 and now it is V2.01.03. Have they released new firmware for the upstream channel bonding or was it capable of doing it already?

Edit: just done a reboot and still on two upstreams, one qam16 and the other qam64. The only difference is that the ranging status on the other two channels is "other".

Re: Uddingston upstream 3 channels?
 

What happened last night? Did something happen on my superhub?

Re: Uddingston upstream 3 channels?
 

The new firmware isn't for upstream channel bonding, it's always been able to do it.

EDIT: Incidentally 4 channel bonding is also out there now.

Re: Uddingston upstream 3 channels?
 

Still on the old firmware here, still on 2x QAM16 upstream channels :(

Re: Uddingston upstream 3 channels?
 

get your change of underwear ready. I was just typing out a reply in another thread about webpages loading slowly when I went to see how much of an impact my torrents were making. When I saw it was 1.9MB/sec I spat my squash out over my keyboard. It has never gone over 1.42MB/sec since I have been on 152/12. I have been watching it for 10 mins and the lowest it has gone down to is 1.6MB/sec and it is holding steady between 1.8-1.9MB/sec atm. I rebooted the shub earleier because I noticed a new firmware revision had come down but my config remains the same (168/12.6). I half want reboot it again to see if anything changes but at the same time I don't want to lose the speed.

Given how much I must have uploaded it is interesting to see that stm hasn't kicked in either!

Re: Uddingston upstream 3 channels?
 

That's....not all that high?

https://www.cableforum.co.uk/images/...2015/07/16.png

There's a reason I don't bother with Torrents.

Re: Uddingston upstream 3 channels?
 

What version is the new firmware?

Re: Uddingston upstream 3 channels?
 

I wasn't talking about downstream, I was talking about upstream

I have always used private trackers and been able to max out my downstream which is why I have been using torrents since they were born.

V2.01.03

Re: Uddingston upstream 3 channels?
 

Ahh, well that is significant! What's your operational config saying?

Re: Uddingston upstream 3 channels?
 

https://www.cableforum.co.uk/images/...2015/07/15.png



My superhub firmware is now on V2.01.03 and its showing 3 active up streams im in Devon

http://www.ultraimg.com/image/DYjY

Re: Uddingston upstream 3 channels?
 

Are these SH1 that have had the firmware update?

Re: Uddingston upstream 3 channels?
 

superhub 2

Re: Uddingston upstream 3 channels?
 

I have got the shub2 as well and my config has remained the same. I was hoping to see a change to 16mbits up (which would explain my nearly 2MB/sec upload speed) so the tier would be back to 10:1 at 160/16. I have just done another reset to satisfy curiosity and I am still on 2 upstreams and only one of them is qam64

Re: Uddingston upstream 3 channels?
 

There are no plans to offer 160/16 or 152/15. There are no plans to return the tiers to 10:1 levels at this time.

Re: Uddingston upstream 3 channels?
 

No updated firmware in Swansea yet.

Re: Uddingston upstream 3 channels?
 

Most areas don't have it yet. It won't make a profound difference to performance in any event and correlating it with the extra upstream channel isn't appropriate, they're nothing to do with one another.

Re: Uddingston upstream 3 channels?
 

Three channels upstream here in Coventry. I'm not sure when that happened - 6 weeks since I last checked.

Software = V2.01.03

Re: Uddingston upstream 3 channels?
 

Purely out of interest - is there are correlation between an area going to 64QAM for upstream and running with more than 2 upstreams? Or are they being changed at different times?

Re: Uddingston upstream 3 channels?
 

Both my changes occurred some time in the last 6 weeks, i.e. from 2 to 3 channels and to the current software. This does not mean, of course, that they happened at exactly the same time, but during that period there has only been one ISP initiated reboot

Re: Uddingston upstream 3 channels?
 

I've been on QAM64 for very a long time but no 3rd upstream for me. I'm in London NW9

Re: Uddingston upstream 3 channels?
 

Same here

Re: Uddingston upstream 3 channels?
 

Me and my big mouth.

They are actually related - modems on the new firmware on the same cable as those without may see 3 upstreams while their older firmware counterparts are on 2.

Note may not will and given there's essentially no upstream congestion right now it makes no difference to performance and isn't an indication of impending tier uplifts.

Re: Uddingston upstream 3 channels?
 

Any news on when the the new firmware will release on the ac hub ? Ignitionnet :p:

Re: Uddingston upstream 3 channels?
 

Just setup my SH2 again and got 3 upstreams :D

Attachment 26255

Re: Uddingston upstream 3 channels?
 

Whatever turns you on :)

Re: Uddingston upstream 3 channels?
 

That makes a change... Wonder how long that will last!

Re: Uddingston upstream 3 channels?
 

Not really; there have been very few upstream issues since upstream bonding was released. Last time it was really broken was when VM were selling 100Mb/10Mb on single upstream channels.

Re: Uddingston upstream 3 channels?
 

:D

Re: Uddingston upstream 3 channels?
 

My three channels are 16QAM each. Is this indicative of anything?

Re: Uddingston upstream 3 channels?
 

it doesn't work like that dude. The modulation directly corresponds to bandwidth and the amount of data that can go over that channel (it is to do with the number of bits per symbol). To keep it nice and simple qam64 provides a 50% increase in bandwidth from qam16 so I think you are roughly looking at going from 20mbits/channel to 30mbits/channel.

If you are using three channels (on qam16) then it is 3x20mbits=60mbits. Using your example, adding the three channel modulations to make qam48 would give you far less than what you currently have access to. What you are missing out on is 3 x qam64 channels which is 3x30mbits/channel=90mbits potential bandwidth.

You haven't got anything to worry about being stuck on qam16, it has been the normal for the last couple of years. In order to achieve the higher modulations your (or VM's network) has got to be a far higher standard and there has got to be less noise. This is why we have seen upstream channels fall back to qpsk in the past; slower connections but more noise tolerant. What some users have already reported seeing is being moved to qam64, but as issues crop up with noise they temporarily fall back to qam16. Things are moving in the right direction and as the shubs re only capable of using 4 bonded upstream channels the way forward for VM is to change the modulation and try and squeeze as much juice out of it as they can.

Re: Uddingston upstream 3 channels?
 

Of course if there's no upstream congestion people are missing out on nothing regardless of the modulations and number of channels in use. :)

Re: Uddingston upstream 3 channels?
 

Doubt it makes any difference, but I have 4 Upstreams:

https://www.cableforum.co.uk/images/...2015/07/26.jpg

Re: Uddingston upstream 3 channels?
 

Mind giving me the first 3 octets of your IP address Mr/Mrs/Ms Duck?

There are some trial areas on 4 upstreams :)

Re: Uddingston upstream 3 channels?
 

Sure...

82.7.217.x

Re: Uddingston upstream 3 channels?
 

congratulation dude, you are the first :dunce:

Re: Uddingston upstream 3 channels?
 

Doesn't work like what? You answered my question. "Is this indicative of anything?"

Re: Uddingston upstream 3 channels?
 

lol, look at you trying to pull a fast one. Your original post which was edited before I had chance to reply:

I was expecting somebody to pull me up for it and ask me what I was going on about but I didn't expect it to be you :doh: So yes I did answer your question quite precisely.

Re: Uddingston upstream 3 channels?
 

Yep, minor edit within 1 minute of me originally posting it. I removed the bit that said 16QAM x 3 = 48QAM. I thought that was stating the obvious and the QAM64 bit because obviously I didn't have 64QAM per channel. Didn't need saying.

Re: Uddingston upstream 3 channels?
 

it isn't stating the obvious because you still sound like you have got yourself in a pickle which is why I tried to explain it for you. 3 x qam16 is not qam48. Read through my explanation again, I probably didn't explain it clearly enough but I can go into more detail if needs be.

Re: Uddingston upstream 3 channels?
 

Nope seen a dude in Lewisham on 4 channels ;)

---------- Post added at 22:06 ---------- Previous post was at 22:05 ----------

Cheers. Combination of curiosity and checking if it's actually supposed to be 4 upstreams so that you don't hit issues if someone accidentally pushed the button :angel:

Re: Uddingston upstream 3 channels?
 

if the capability is already there to bond 4 upstreams shouldn't VM "hit the button" and do everyone is one go right now? Surely it is a win-win and can only help VM by reducing congestion? (similar to making 8 downstreams available to everyone whether they need them or not). It would definitely give them some breathing room while they sort qam64 out.

Re: Uddingston upstream 3 channels?
 

It can break things. It's not as simple as pushing the button.

I'm not entirely sure why they are choosing to upgrade some but not others in the same areas.

If there's no congestion there are zero reasons to potentially cause problems by bonding more channels though.

Re: Uddingston upstream 3 channels?
 

I am very capable of getting myself in a pickle when it comes to network technicalities. On this occasion I hadn't because I had read earlier posts.

My interest in the details on this occasion are driven by a keen enthusiasm for any signs that the network might be getting upgraded for future speed hikes.

Re: Uddingston upstream 3 channels?
 

:shocked:

Re: Uddingston upstream 3 channels?
 

I know it's not 4 but look what I have just woken up to :)

https://www.cableforum.co.uk/images/...2015/07/24.jpg

Re: Uddingston upstream 3 channels?
 

Wonder when the 2ac will get the new firmware? Having said that my upstream power has jumped up from 47 to 52dBmv since yesterday, so I'd rather that was sorted first.

Re: Uddingston upstream 3 channels?
 

Same! And I got the new hub firmware.

https://www.cableforum.co.uk/images/...2015/07/14.png

I guess the firmware is more for the hotspots?

Re: Uddingston upstream 3 channels?
 

sweet, hopefully we'll be on qam64 in no time

Re: Uddingston upstream 3 channels?
 

I got the fw update last night (SH2, modem mode). Today I've noticed I'm now on 8 downstream (256qam) and 3 upstream (64qam) channels. I wish they'd hurry up and release >gigabit services. We're looking to move house this year and I'm already trying to twist my wife's arm to move half an hour down the road to where they have b4rn FTTP. :D

Re: Uddingston upstream 3 channels?
 

you won't get gigabit on VM for at least another 5 years.

1) They need to rollout 300mbits on existing infrastructure and cpe which will be an 18 month rollout schedule
2) They will then moved onto docsis 3.1 and need to trial new cpe and there will no doubt be a new tier of something like 500mbits (or maybe 750) with another 18 month rollout schedule
3) Gigabit will come around with another 18 month rollout schedule
4) That is 4 and a half years without delays so add another 6 months.

Re: Uddingston upstream 3 channels?
 

Definitely easier to move house... ;) B4rn offer 1Gbps and 10Gbps symmetric presently. I'd move in a heartbeat (it's a nice ruralish location not too far away), but my wife thinks it's too far because of 'family' and 'school'. Meh. :naughty:

Re: Uddingston upstream 3 channels?
 

Given that the firmware update has apparently nothing to do with the extra upstream channels, there's a lot of people getting both at the same time.

Re: Uddingston upstream 3 channels?
 

Re: Uddingston upstream 3 channels?
 

Oops, I missed this post.

Upload STM removal confirmed! :D

Re: Uddingston upstream 3 channels?
 

Alongside reinstatement of the 10:1 ratio with 5:1 planned for the end of the month, naturally.

Re: Uddingston upstream 3 channels?
 

please don't wind telfordcable up

Re: Uddingston upstream 3 channels?
 

This a wind up?

Re: Uddingston upstream 3 channels?
 

He's already got 16x QAM512 upstreams and a 1:1 ratio.

Re: Uddingston upstream 3 channels?
 

Nah he's fine. He doesn't care about cable, he wants fibre to the premises so FTTN/C won't cut it.

As I remember he was last claiming to be on a non-existent tier at a non-existent price point.

He then posted elsewhere having forgotten that he was supposed to be on Virgin saying that he had no interest in VM.

I see his posts across at least 4 forums.

Re: Uddingston upstream 3 channels?
 

I am so glad he as got the time to sit down and come up with all the bs.

Re: Uddingston upstream 3 channels?
 

He can always go to one of the many other cable providers that Telford has to offer.

Re: Uddingston upstream 3 channels?
 

I am sure he has founded his own company by now and has a multi terabit link to the backbone

Re: Uddingston upstream 3 channels?
 

I'm now back on 2 upstreams :(

https://www.cableforum.co.uk/images/...2015/08/28.png

Re: Uddingston upstream 3 channels?
 

Still on 3 in Uddingston, Have you tried a reboot to see if it comes back ?

Re: Uddingston upstream 3 channels?
 

arse, me too. I have lost my qam64 channel

https://www.cableforum.co.uk/images/...2015/08/25.jpg

Re: Uddingston upstream 3 channels?
 

As long as there was no congestion that the additional channel mitigated it's fine. Far better the upgrade is handled properly as areas are ready than apparently all over the place with a modem firmware upgrade that's not really a part of the preparations.

Re: Uddingston upstream 3 channels?
 

it is alright it is back now. My connection got increasingly slower yesterday evening (like it was winding itself down :)) and around 10 ish just came to a complete halt. I whipped the power cord out of the shub and popped it back in and now I am back on 3 channels and my qam64 is back

https://www.cableforum.co.uk/images/...2015/08/24.jpg

Re: Uddingston upstream 3 channels?
 

Still gone here :(

Re: Uddingston upstream 3 channels?
 

So far I have noticed that whether people have 2 or 3 upstreams, and whether they have 16QAM or 64QAM the mini-slot size is 4.

I have the VMB business service and see a Mini-slot size of 128. I wonder the significance?

https://www.cableforum.co.uk/images/...2015/08/23.jpg

Re: Uddingston upstream 3 channels?
 

especially strange given how completely different they are

Re: Uddingston upstream 3 channels?
 

There's none; different firmware is giving the same result but in different units.

Re: Uddingston upstream 3 channels?
 

FWIW historically 128 MS size has been related to SH1(VMDG480) hardware/firmware combo's. One related to number of ticks(6.25 micros), and the other bytes....

Re: Uddingston upstream 3 channels?
 

Care to explain-like-i'm-an-idiot as to what the mini-slot size actually is and what the numbers mean?

Re: Uddingston upstream 3 channels?
 

Re: Uddingston upstream 3 channels?
 

Yes. If I remember rightly the SH 1 is a Broadcom SoC while the later revisions are Intel. Probably explains the discrepancy.

Re: Uddingston upstream 3 channels?
 

Correct

Re: Uddingston upstream 3 channels?
 

Sooo....what's the mini slot size, then?

Re: Uddingston upstream 3 channels?
 

http://volpefirm.com/docsis101_anatomy-of-a-burst/

It's clearly described in the first paragraph...

tl;dr:

A time slot.

Re: Uddingston upstream 3 channels?
 

yeah but thicko here is none the wiser as to what that means :)

Re: Uddingston upstream 3 channels?
 

Cable uses TDMA for upstream:

https://en.wikipedia.org/wiki/Time_d...ultiple_access

tl;dr:

Upstream channels are shared using TDMA. In TDMA, multiple modems cannot transmit at the same time. Each second is divided into thousands of slots, and these slots are dynamically divided between modems. Each modem then transmits in it's assigned time slot(s) so they don't interfere with each other.

And quoted from BV:

It's actually much the same as 2G (GSM) mobile phones.

Re: Uddingston upstream 3 channels?
 

so presumably the time slots of larger on the business server (meaning less of them) because there are far fewer users compared to the residential service and thus thousands of slots don't need to be available per second in order to ensure everyone can transmit

Re: Uddingston upstream 3 channels?
 

People on the business service connect to the exact same kit as people on the residential service and use the same upstream and downstream channels.

As I mentioned there is no difference between the mini-slot sizes, just how they are written - one in bytes the other in ticks.

Re: Uddingston upstream 3 channels?
 

my upstream is back to kick ass speed again. It is defo something to do with the addition of the latest upstream channel. I used to max out at 1.42MB/sec but since the addition of a 3rd upstream channel it has been averaging 1.6-1.7MB/sec and atm it is edging towards the 2MB/sec mark which isn't bad for a Sunday evening.

https://www.cableforum.co.uk/images/...2015/08/13.jpg


Interestingly though, every time it starts to push itself it locks up. I think I have mentioned this in two other threads over the last few days and it has only started happening since the last firmware release/last upstream channel addition. In the two mins it took me to take the screen dump and cut it up, I went to type this out and upload the pic only to find I had lost my connection. All the leds on the shub were solid blue and I had to reboot it to get everything back to normal again. Might be something you want to get them to look in to because it is happening every 2 days now. I have had this shub for over a year and not had to reboot it once up and till now.

Edit: rebooting the shub has caused me to lose my 3rd upstream channel again. Interestingly though a qam16 has gone and not the new qam64
