3.1 upstream channel?


[link to this post]
 
Hi,

VM are doing some work in my area and I lost my internet connectivity briefly today only to find now I have 5 x 3.0 upstream channels and 1 x 3.1 upstream channel.

Is this a sing of faster upload speeds on the way?

Sounds good, do you have a Hub 4 then?

Is this likely to reduce congestion? I believe that is the weak link on VM; so with 50% more upstream channels more capacity to go around?

[re: mr_mojo] [link to this post]
 
I would assume yes but with the caveat user usage stays the same, and they dont up the speed on the packages, I expect a speed uplift is happening.

I am back on VM as of today, not sure yet if keeping it, but I have seen mild congestion creep in after 8pm Mostly visible on the upstream which cant top 40mbit now, was over 50 earlier. Downstream a little slower but single threaded not affected so streaming would be fine.

However compared to the last time i was on VM this is a considerable improvement and the level of congestion is not really interactive service affecting. Hopefully dont see it get worse. TBB graph doesnt look terrible either.

For reference I only see 4 US channels which means I probably also dont have 3.1 US channel, once they get round to my area, it should solve this US issue.

I think if they deployed 3-4 3.1 DS channels and at least 12 3.0 US channels VM would be golden everywhere.

Most 3.1 modems can only lock to 2 OFDM downstream blocks and no modem locks more than 8 SC-QAM 3.0 upstream channels.

The downstream OFDM blocks go from 24 to 192 MHz wide. At 14 bits per Hz 2 of those will be just fine for 2 Gbit to a single customer even without the 32 3.0 downstream QAMs the modems lock to.

3.1 upstream is way more efficient: it'll go up to 2k QAM if the plant is clean enough and can drop individual carriers if there's narrowband noise instead of the entire channel. It comes in channel sizes between 6.4 MHz, the current SC-QAM size, and 96 MHz - equivalent to 15 3.0 channels but with modulation orders way higher.

One OFDMA block upstream should be good for the foreseeable. The plan will be, in coaxial areas, to turn off the 3.0 carriers and enlarge the 3.1 block as customers move off 3.0.

There isn't enough spectrum to have 12 * 3.0 channels regardless. Would need 76.8 MHz of clean upstream which isn't there. The spectrum is flaky below 20 MHz and ends at 85. 5 or 6 SC-QAM and the 3.1 OFDMA should be fine for new speeds. Usage hasn't gone up much with folks going to Gig1 it's mostly the same stuff faster.

The RFoG areas are a different story. They can't have 3.1 upstream so will have to be packed with 3.0. 8 of them ideally.

Thank you for that explanation, so yeah once I have that 3.1 US I should be good.

Speedtesting on pfsense seems to struggle a little bit multithreaded. So will look whats going on there, is likely a pfsense or PC issue at 3.40am and on laptop it was fine with hub5 in router mode.

If you curious here is the tbb, way better than it used to be in my area.

I spoofed the router mode mac to keep same ip.

There aren't going to be any more spectrum upgrades so what people have once the upstream channels have all been deployed and the spectrum up to 85 MHz filled are all they're getting with the ratio of 3.0 to 3.1 capacity changing.

The major forms of capacity relief will be moving customers to 3.1, heavy users offloaded to XGSPON and node splits only as a last resort.

VMs FTTP target dates still many years away do you think the system will hold out until then?

It is logical they going to basically stop investment on the current stuff as its effectively no longer the long term plan.

Yes. The existing spectrum is good for 2000/200 or more with 3.1. Nodes will still be split, just no additional spectrum added: that would cost nearly as much as the FTTP build.

All I can say is Cambridgeshire is one of the first planned for FTTP overbuilds as I had the conversation with someone who "spilled the beans" under interrogation. To be fair my area must be up there as I can see all the streets around mine are currently undergoing VM FTTP overbuild.

Not sure why they upgraded our upstream to DOCSIS 3.1 over 4 months ago (I think it is now) if they just plan to FTTP in months to come.

I know my performance hasn't improved that much since the work.

Take a look at todays BMQ for an idea BMQ 2022 10 30

Everyone isn't moving over at once. People will be moved as they ask to be. VM may prompt them but won't compel them for years.

VM have tens of thousands probably more customers served by the Cambridge heasend and its hubs. That's a lot of truck rolls to install FTTP.

The HFC will be operating for years yet even in the very earliest areas to receive FTTP, and there are plenty with build underway and some areas where much of it is finished and awaiting key equipment install then it's good to go.

The HFC will still be maintained and still receive some upgrades just not costly spectrum upgrade. The decision between spectrum and FTTP was an either/or, not both.

HUB4, not seeing any issues to be fair, seems quite stable recently.

I also have a samknows whitebox, shows similar stable connection.

My weekday graph is almost like a permanent night time graph. There must have been a lot of work in my area here since I was last on VM. Today's windows updates downloaded in about 1-2 seconds at over 50MB/sec. I think I dont need any downstream shaping now on my firewall, if I do download activity its not visible on the graph or noticeable on interactive use.

Yours is better you do get max US 24/7, I just ran another test just before tucking in for an early night, this one was about 35mbps but as you can see ACK's still not affected for downloading.

Hopefully the 3.1 and 5th 3.0 channel wont be too long.

Kinda. OFDMA multiple modems will want to burst at the same time with very little wavelength separation as they can each take some OFDMA carriers from the same block simultaneously. This doesn't impact the hybrid network, they just transmit at the different frequencies and the RF is aggregated by the network, however RFoG two lasers bursting at the same time at such close wavelengths causes Optical Beat Interference - lasers drift a touch in wavelength as they warm up.

https://www.commscope.com/globalassets/digizuite/165... explains this along with suggestions to mitigate it in excruciating detail. I'm not going to claim to understand this very much: it's way beyond me.

VM could use these mitigations, or they could just use more 3.0 upstreams until it's not enough then introduce XGSPON.

Did a few more tests randomly at peak, US now ok, also now set a fq_codel for it to keep latency down during uploads, seems no need to shape downstream though with this capacity, every single peak test has been perfect for downstream, no issues streaming, youtube, netflix etc.

Ok got a response from VM.

The hub site is 50mhz spec and the spectrum isnt available in my area for a 3.1 channel, it wont be coming in 2023, of course given at some point a stop will be put on DOCSIS, I am assuming at this point it means no.

So this I guess confirms the 3.1 US is not going to be universal around the country.

I will be keeping the package though as everything downstream related has been perfect, I am not even seeing flickers of visible contention at 9pm in the evening.

Hmm, that sounds like we're going to have to wait some time for any upgrade.
Things are OK for now as you say, but who knows in 6 months time with VM.

Is CityFibre live in your area yet? We had all the groundworks here over the summer, but they still haven't installed the CBT's on all the poles, or even connected to the tubes at the base of the poles.

I see VM have a Black Friday deal for standalone broadband, hopefully not too many new customers on our area!

Cityfibre are live to about 30m from me, they went to the property next to me and then did a 180 over a year ago. .

I got an email from them saying they coming etc. about 6 months or so ago, a bunch of roadworks have been done, but I noticed they had stopped activating postcodes so started pushing them, I then pushed some more after my VDSL hit problems and eventually got a response they wont be doing any more activations for at least 9 months in the city, I was quoted specifically minimum 9-12 months, I then proceeded to order VM.

So I think I will be lucky to have CF availability by end of 2023.

No, only active up to the bridge on Fosse Road, I'm further along near Western Park.
Some markings on the pavements appeared this week, assuming blocked ducts that are holding things up? Nothing newly available on the coverage for quite a while now in the city.

The streets off Pool Road have had CityFibre round, and now Grain are there, nothing is live yet. I don't expect anything till neat year to be honest, they aren't in a rush!

Seeing some peak time latency spikes which is the first I've noticed since I've had it for a couple months. Maybe football related,

I'm on Gig1. Is it likely there will be a 3.1 channel enabled and would that help with pings at peak times if they do?

Edit to add: Just doing some digging in the logs and it seems there is something going on with upstream channels, quite a few messages like this in the past few days:

US profile assignment change. US Chan ID: 12; Previous Profile: 12 13; New Profile: 11 13.;CM-MAC=xx;CMTS-MAC=xx;CM-QOS=1.1;CM-VER=3.1;

I can't see an US Chan ID 12 (only 6-10 on the upstream list), but the Ver3.1 maybe suggests it is a 3.1 upstream channel?

@XGS_Is_on what do you think of this claim here?

https://community.virginmedia.com/t5/Speed/BQM-Check...

Poster claims upload boost is coming soon but will be limited to areas that have the bigger return paths, would this be a first for VM to have variable speeds based on location? He did get it right on the 50mhz return path 3.1 status as that matches what VM exec office told me.

Phil check your hub, despite what I was told, I now have the 3.1 US channel, and a 5th 3.0 channel.

Just speed tested and full speed uploading at 7.30PM. smile

Graph back to as good as it was before the speed uplift's as well.

Got the new channels same as you. According to Samknows we had a 55 minute outage at 12.30 on 01/03, perhaps something was done then?

Graph is still a bit messy tho!

My Broadband Ping

Uploads haven't really been impacted for us, but samknows monitoring is still below 950MB (which I suspect is the limitation of the LAN). If I do a test using the Virgin hub its always above 1100MB (conveniently!).

Our issues are normally slow loading and poor response from webpages etc.
Kids are happy and not moaning so I'm happy!

Cityfibre finally have installed the CBT's round here so looks like we will be going live sooner rather than later. Virgin contract ends in November.

Yeah your graph looks nowhere near as good as mine. On jitter sensitive stuff like SSH command line it feels no different for me now vs DSL.

I dont know what the CBT's specifically look like, I took a pic just now of my pole, it has my side a rectangular blue box attached, and I think maybe smaller black one the other side.

There is also road markings outside every property which I assumed is where they putting them but nothing placed there, I suspect CF is at least a year away for me, I was told late last year minimum 9 months. There has been no local CF works near me for a while now, neither is there any planned within 3 months, they instead just been moving progressively further and further away with no activations occurring. When I was checking my archived emails earlier for something else I found the one ones from Zen alerting me CF is coming soon, dated spring 2021, it really has been taking CF an eternity to do the local rollout.

But VM is currently working really good for me now, its been far more stable than DSL (ttb was having regular outages before I cancelled and sky also did over night maintenance a lot), on VM I have had one unexplained hub reboot which thankfully only happened once, a firmware update, and the upstream channel upgrade. So pretty good.

The blue box my side on my low detail picture has no cables attached to it, but I think I can see the outline of a cable the other side, when its quieter later I will get closer to the pole and check the other side.

Are your CBTs on the ground or the poles?

The CBT for me is on the pole, had a purple tube sticking out of the ground since August!
Its a black box at the top, opposite side of the pole to the existing OR one.

The have put a few new poles in too where the drops are too long. Some houses have had buried tobys put in too (Glenfield Road near Fosse Road and the new houses Gimson/Nevanton Road).

Also had Openreach round last week surveying for FTTP too, checking chambers and ducts, they also are putting some more poles in!

From atrocious ASDL to overload of FTTP and Cable in 5 years!

I assume Virgin will also be doing their fibre upgrades too, however the RFOG is not good for latency, mu sister is on it in Syston and her ping is 20mS minimum, double mine.
Lots of dropped packets too.

Here is a pic of my pole but because I was at distance zooming in lowers the quality.

I think my 3.1 US channel is flapping, looked at the log to help someone on the internet, and my US channel looks like it keeps dropping and coming back, actual service seems ok including speed tests, but my TBB graph has a thick blue line since this started in the logs and base latency moving up and down as well. Hopefully will settle down.

Graph looks normal from about 4am today, it was for the full 24 hours yesterday.

Granted could be totally unrelated.

Seems ok now, I suspect it was roadworks related, was drilling vibrating the property on those dates, so even if the problem comes back I will leave it until they stopped working outside my home before considering reporting it.

Just checked my BQM, and it looks the best it ever has!
How did you see the channel dropping?

Something changed on 16th Feb.

Graph from 15th
My Broadband Ping


Graph from 16th Feb
My Broadband Ping


Checking my SamKnows whitebox data it seems that the connection is stable and speeds are good up and down. I do see some random disconnections on the data, but not sure these are actual issues because they aren't evident on the BCQ graphs?

I do wonder how old the actual cables in the ground are now, and that the latest technology may be pushing the physical infrastructure? Roadworks shouldn't affect the connection if they aren't actually interfering with the physical cables? Unless there is a fault with the same cables!

I'm currently in discussion with Virgin due to my bundled O2 SIM now on its second price rise in 18 months, despite Virgin assuring me that my contract will not increase until 2024. Maybe its time for a change until Virgin actually upgrade to FTTP to stabilise the connections.

Am not sure its actually dropping, but basically the hub5 doesnt show the 3.1 channels normally. So the logs show when the channel is activated, the 3.1 DS channel only activates once as would expect, but my 3.1 US channel was flapping between different profiles alongside some T3 timeouts on it as well.

However it seems to have stopped yesterday. By coincidence the heavy equipment stopped been used by the workers then as well.

So the plot thickens!
Virgin sent me an email saying I was not going to be impacted by the price increases, it seems that I am according to the guy at retentions I spoke to yesterday.
They wont budge on the O2 increases, even though I didn't actually sign up myself!

On another note, it looks like Openreach are pushing forwards with their FTTP roll out here, lots of activity with new poles and people looking into chambers, nothing for years except oversubscribed cable, now were going to have a choice of at least 2 FTTP. Who knows if VM do buy out cityfibre!

The Virgin connection does seem to be stable recently tho!

OR officially are only planned in a few parts of Leicester, looks like you might be in that catchment area, I am not that far from it, but not in the net. I have too seen some OR work, but it might be just to support the official areas, officially my street isnt planned.

But I would prefer CF fibre anyway and thats the one coming here, as I do think the upload speeds on OR FTTP are extremely scrooge, and that would be the only thing that would perhaps move me away from VM now, as the service has been much better than I was expecting.

I agree, even for me with no OR its quite the turnaround.

Talking of VM emails, I have just had my 2nd boost your broadband email from VM, they seem to have forgotten I am already on the top tier.

Need to think who is the worst at spam VM or EE, 6 texts from EE within a month trying to get me to buy expensive devices, 5 emails from VM advertising alternative services.

No price rise for me this year as well. Never got an email for it which is funny with all the spam, but was informed by letter. smile

Flapping seems to have stopped on the 3.1 channel.

Channel seems flaky again here.

16 consecutive t3 timeouts on the 3.1 channel and a "Unicast Maintenance Ranging attempted - No response - Retries exhausted" on the 3.1 channel as well.

The hub 5 with its UI bug of not showing 3.1 channel status, kind of leaves me in the dark, but tbb graph still looks stable and I uploaded videos at full speed today, so service is ok at least.

Still no speed upgrade here, stable enough connection for us now but was hoping that the recent works was for enabling the faster upload.

Intresting that Openreach seemed to manage to install the FTTP infrastructure here in weeks, while CityFibre still not ready after over a year!

VM contract is up in August, decisions to be made, was hoping that when I renewed in March 22 that CF would have completed the build by now!

At my address CF is green now, build completed, but they havent done any ISP connectivity.

AAISP queried for me but were told their side not yet available.

My plan is to get a 160/160 service from CF (which also gives me 160mbit upload), run it alongside VM up until about 2 months before end of VM contract, then will bump to 1000/1000, and if all is good will cancel VM next April end of contract.

So 1160/210 before I go exclusively CF.

Cant fault the downstream which is the main use of the connection, have been downloading games during peak and coming down full throttle.
