FTTC - what's the point???


[link to this post]
 
Well, it finally came to our village. I found out by accident and was on the phone to the ISP the next day. The line tester was predicting speeds of 12-19Mbs. I couldn't wait...
Two weeks later, it was all done!!! YAY.

With bated breath, I logged in a did a speed test. Result before, (with ADSL) ~5Mbs, after (VDSL) ~ 6.2Mbs - wow!!!!

What an anticlimax. I have been on to tech support and we have tried various things but that is what it is. And, yes, I am plugged into the test socket.

The odd thing is that the BT wholesale speed checker tends to give results around 10Mbs (sometimes it's as low as 6 but 4 out of 5 times it's 10 or even a touch more).

I have tested with TBB speed test and Ookla, same result. If I download one of the TBB test files, sure enough, around 6.

I'm about 1500m (by road) from the cabinet (which, ironically is a about 100m the *other* side of the exchange).

The ISP says that they can't log a fault with BT as it is within the "tolerance band" or some such excuse.

So, is there any point to FTTC, is it all a just a big sham???

By the way, if I try to run the 'further tests' on the BT speed-checker, it fails with the message 'The Performance Tester is currently unable to run a speed test for your broadband connection.'

Good word that: anticlimax. It was for us, too. From 20Mbps LLU ADSL2+ to circa 25Mbps VDSL2.

Maybe get an unlocked modem; study the max data rate, attenuation, and whatnot.
At least you can gauge whether you should expect any more.

Surprise perhaps that they even up-sold you to VDSL2 when you're 1500m+ from the cabinet.

And your slight up-lift in speed -- from 5Mbps with ADSL to 6.2Mbps with VDSL2 may be short-lived.
Initially we had a max data rate of nearly 50Mbps, but over 18 months, half of that's been lost to crosstalk.

BT may postpone the inevitable by rolling out cheap fixes to the copper (G.Fast and the like) but the only solution for people like us is fibre all the way.

Is there much of a financial premium for that uplift of 1.2Mbps? If it's the same price and a stable service, maybe stick with it? What about the upstream? How much has it been boosted? Here's where we did gain something. Previously we got 1Mbps upstream on ADSL2+, but now get 6Mbps. An improvement but not hugely useful, as we don't host, nor fileshare much. Shame the VDSL2 isn't more dynamic in its allocation of spectrum between upstream and downstream bands.

Well the upstream is just as important as the downstream, whether you file share, host or not.
If you have no more spare upstream you cannot request for stuff to be downloaded.

Basically every time you request a webpage you are requesting a page and then requesting several or upwards of more files like images css stylesheets and so on.

Stuff that stream like media also uses your upstream when watching or listening to music etc, every time it asks for the next block in the stream its uses upstream bandwidth.

And when there is no more upstream left you cannot download anything else.

Granted these request packets are on the small side, but they all mount up, especially if multiple uses on the connection are doing stuff.

If you go to BT wholesale performance test and run the speed test.
http://speedtest.btwholesale.com/
hen click further diagmostics Put in your phone number and it should give you some indication of what speeds are available at the exchange.

hope that helps a little
(edit)
oppss miss the final paragraph - mmm intresting i wonder why further diagnostic wont run. When i was having connection problems and my download speeds dropped to les tan 2 meg I was still able to run Btw diagnostics

Hi Millie, and welcome to the forums.

About your own problem with the BTW diagnostics, have you changed ISP to an LLU one since it used to work for you? That would cause this, as the Further Diagnostic part doesn't recognise LLU phone numbers. Also, all we gain from the Further Diagnostics is the IP Profile, and LLU suppliers don't have one. It only applies to BTW connections.

(Friendly tip - every post has its own reply button, so you can reply to the actual post/person, in this case the OP rather than me smile. You can see it in the post headers. If you switch to Threaded mode, which lots of people use, you can see how it chains conversations (sub-threads)).

I have plugged the modem/router into the test socket (and disconnected the extensions). With the extensions in place, speed dropped to 2-3 Mb/s. I haven't done a QLT. I'll check it out when I get back home.

No, the impact has been the £40 setup fee and then I am tied into a 12 month contract where I was on a 1 month one. Not a major issue as I don't expect to leave the ISP.

Upstream is slightly better than ADSL but still only ~1.5Mb/s

I don't know if VDSL is likely to be more stable than ADSL.

Sham no - just a reality of physics and that the vast majority are well within 1km of their cabinet.

At 1.5km if that is 100% accurate I would say speed is slightly low, but road distance may be an under estimate by 200 or 300m which accounts for things.

For the minimal time and no cost involved, surely worth carrying out.

Also, note the Speed Drop that the OP mentions, when his router is plugged in to the NTE directly, compared to when the normal extension wiring is included.

Not if there isn't audible noise on the phone when connected normally.

What his speed drop suggests is that the bell wire is connected, and/or the internal wiring is duff.

Agreed that amongst other things, these could be causes.

But not having carried out the QLT; and as so many nowadays, rarely, if ever, use their land-lines, then the QLT is a Quick, No Cost route to follow.

You are almost certainly aware that both BT and SKY recommend its use at an early stage - and if he does so and finds No Noise, then he is in a stronger position to negotiate with his ISP.

And it may help to avoid the relatively high charge that BT/OR may make to his ISP, then passed on to him.

OR is that a bad thing, to avoid such charges?

What is the sync speed quoted on your modem?

If you were getting 6.2Mbps and the estimate was 12-19Mbs, I believe the ISP could report it to BT

Given you can actually get 10Mbs from the wholesale speed test at the master socket,I suspect the problem is either likely to be at your end (eg extension wiring) or peering/contention issues at your isp

Just checking ... You do realise that the BT estimations are usually of sync speed? Not the throughput of a speed tester?

Running speed tests is absolutely fine for checking that performance stacks up against the sync speed being achieved, and for checking that all the hardware is working together. However, the speedtest results aren't meant for comparison against the line speeds specified by the BT estimator.

The BTW estimation tool comes with the proviso: "Throughput/download speeds will be less than line rates and can be affected by a number of factors within and external to BT's network, Communication Providers' networks and within customer premises."

With a speed of 6.2Mbps, and an exchange distance of around 1.6km, I guess you are on 20CN ADSL. If you had access to ADSL2+ (21CN), you'd probably be getting speedtest results closer to 15Mbps.

In reply to a post by filbert42:
The ISP says that they can't log a fault with BT as it is within the "tolerance band" or some such excuse.

The estimated range represents the 20th and 80th percentiles of speeds of similar lines. BT will accept a fault from the ISP only if you fall into the bottom 10%, unless the line testing equipment also reports a physical fault.

I guess the gap between the 20th percentile - bottom of the estimated range (12Mbps line speed, or sync speed) - and the 10th percentile is this "tolerence band".

If things continue badly, or get worse, it might be worth regular reports into the ISP. They'll keep running the line tests and, who knows, one might fail one day.

Telecoms is all about the statistics. Like everything, FTTC is useful to some people, not so useful to others.

The statistics say that, when you consider your total loop length measured to the exchange (1500m + 100m = 1600m), it is comparatively short: you are in the top 15% of the country.
http://postimg.org/image/dm5cc5tx5/

On the other hand, the same statistics say that the loop length to the cabinet, the D-side only at 1500m, is comparatively long: you are in the bottom 4% of the country.
http://postimg.org/image/bp372fcnn/

The combination together doesn't happen often - so you are comparatively rare. I would guess at less than 0.5% of the country.

But more than 90% of the people in the same position would likely have had a choice of 21CN ADSL2+ (like @edwincluck), and stuck with the 15Mbps+ offered by that. That puts you into a group of around 0.05% of the country ... or around 14,000 premises out of 28 million.

Thanks for the very full reply, WWWombat.

I have to admit that, although I have a reasonable technical background, I don't understand all the technology here.

As far as I can see, my exchange (Suckley - WMSUC) has ADSL Max but not 21CN.

I also didn't expect the sync speed to be radically different from the download speed (and, indeed, my router says it's 6733 and I get download speeds that are near that). What I don't understand is why the BT wholesale speed test is so variable and often so far from reality.

If I look at the BT broadband availability screen, I get results that say that "FTTC Range A (Clean)" speeds are from 12.8 to 19.6 Mbps and "Range B (Impacted)" speeds are from 5.3 to 14.4 Mbps.

I am at the bottom end of "Impacted" and the screen explains what it means by "Impacted" but doesn't tell me how I can find out whether my line is in that category or not. Or whether things can be "fixed".

I have done a quiet line test and it sounds nice and quiet to me.

As for being in the 0.05% there are times when one would prefer to be among the masses! I think I might have to wait for Fibre To The Pole (which is just across the road from me) - which is what I think G.Fast means.

The current position is that my ISP has asked BT to look into it and will absord the charge (I won't post the name before the whole process is finished, I don't think it would be fair to them)

It's one of those Tecnicolor boxes (TG598v3). Here is a screen-shot of the main page, which I think, gives what you are asking for:

Router Stats

Here's a copy and paste of the text:

Broadband Connection

2.1 Type VDSL
2.2 Status Up
2.3 Uptime 1 days 21 hours 42 mins 7 secs
2.4 Line Rate (Down / Up) 6733 kbps / 1285 kbps
2.5 Noise Margin (Down / Up) 6.3 dB / 6.9 dB
2.6 Attenuation (Down / Up) 35.6 dB / 17.3 dB
2.7 Power (Down / Up) 9.6 dBm / 10.5 dBm

Is there anything more that is useful that I can get from it?

So in your opinion what is the speed someone should expect with VDSL2 attenuation of 35dB?

I'd suggest in the 4 to 10 Mbps region, but with the caveat that at those distances VDSL2 performance is far from totally predictable

I just had a quick look on MyDslWebStats to see sync speeds others are getting for around the same attenuation and these speeds appear to represent the lower end.

I think 10Mbps should be possible given an ideal connection but I don't know how bad the wiring is between the modem and the cabinet.

Thanks, I'll have to google the stats issue as I have no real idea what the ones I do get really mean and what extra ones would be useful.

I guess I could get an HG612 on eBay, use it to check my line and sell it again when I have finished, so it wouldn't cost a lot.

I notice that, on the ping monitor, mine has a lot more yellow than most but the green bit went down when I moved to FTTC.

As far as I can see, my exchange (Suckley - WMSUC) has ADSL Max but not 21CN.

Yes - that is indeed the case.

What I don't understand is why the BT wholesale speed test is so variable and often so far from reality.


I have to admit, I don't find it very trustworthy for giving me an idea of real throughput speeds. I find speedtest.net to be more reliable for me, especially when I ask it to use a London server or the Vodafone one in Newbury.

The BTW tester tends to be left for two purposes
- To see what IP profile is being reported by BT (for which you needto see the "extra diagnostics" at the end
- To run tests that the ISP can see

In reply to a post by filbert42:
If I look at the BT broadband availability screen, I get results that say that "FTTC Range A (Clean)" speeds are from 12.8 to 19.6 Mbps and "Range B (Impacted)" speeds are from 5.3 to 14.4 Mbps.

I am at the bottom end of "Impacted" and the screen explains what it means by "Impacted" but doesn't tell me how I can find out whether my line is in that category or not. Or whether things can be "fixed".

The screen gives you a flavour of what it means, but even BT internal documents aren't tremendously clear as to what the two ranges mean, and when they should be applied.

However, the checker was upgraded to cater for self-install FTTC, a couple of years back, and that upgrade is what introduced two ranges. That's a clue as to why two ranges exist...

The BTW FTTC Handbook advises ISPs that, when offering a speed estimate to end-users, they should use the impacted range for self-install.

However, it doesn't explicitly tell ISPs when to use the clean range - we just have to assume they mean that it applies to engineer installations. The theory being that an engineer's tests will ensure that any wiring issues or copper line conditions are fixed during the installation, whereas they would be left in place in a self-install.

That, at least, gives us an idea of how an ISP should use the ranges when giving you an estimate before installation.

The document also explains the circumstances when Openreach will reject the fault (the 10th percentile I mentioned earlier), but that doesn't mention which range Openreach will choose to use.

The document also doesn't cope with complex issues, such as where you start out with an engineer install, but migrate to an ISP with a self-install. What threshold should the new ISP use? Or the case where a self-install happens, gets poor speeds, and a subsequent engineer visit fixes things. Should this now have a clean threshold?

All in all, it leaves things murky for fault fixing.

The best thing you have to go on is the speed estimate you were given during installation. But even that can be wrong.

As for being in the 0.05% there are times when one would prefer to be among the masses! I think I might have to wait for Fibre To The Pole (which is just across the road from me) - which is what I think G.Fast means.


It is indeed frustrating to fall outside the norm sometimes.

Unfortunately, while G.fast was originally designed to work from the DP on the pole (hence the term FTTdp), it looks like it will work well at much longer distances, so BT are re-evaluating just where in the network they will site the nodes.

It seems likely that the first round of installation (2017-2020) is very much likely to deal with the area immediately surrounding the existing cabinets.

But who knows where the new iteration of on-demand fibre could go over the next few years?

The current position is that my ISP has asked BT to look into it and will absord the charge (I won't post the name before the whole process is finished, I don't think it would be fair to them)


What was your estimated speed when you signed up? And was it a self-install, or engineer-install?

In reply to a post by filbert42:
Well, it finally came to our village. I found out by accident and was on the phone to the ISP the next day. The line tester was predicting speeds of 12-19Mbs. I couldn't wait...
Two weeks later, it was all done!!! YAY.

With bated breath, I logged in a did a speed test. Result before, (with ADSL) ~5Mbs, after (VDSL) ~ 6.2Mbs - wow!!!!

What an anticlimax. I have been on to tech support and we have tried various things but that is what it is. And, yes, I am plugged into the test socket.

The odd thing is that the BT wholesale speed checker tends to give results around 10Mbs (sometimes it's as low as 6 but 4 out of 5 times it's 10 or even a touch more).

I have tested with TBB speed test and Ookla, same result. If I download one of the TBB test files, sure enough, around 6.

I'm about 1500m (by road) from the cabinet (which, ironically is a about 100m the *other* side of the exchange).

The ISP says that they can't log a fault with BT as it is within the "tolerance band" or some such excuse.

So, is there any point to FTTC, is it all a just a big sham???

By the way, if I try to run the 'further tests' on the BT speed-checker, it fails with the message 'The Performance Tester is currently unable to run a speed test for your broadband connection.'


The problem is that to "promote competition" Ofcom insisted BT allow other companies to install LLU kit in exchanges, meaning that each exchange contains 3-5 sets of the same equipment for different providers. This means they have to keep old non fibre ADSL running (rather than switching everyone to VDSL or even ADSL from the cabinet) and they have to hamstring VDSL (FTTC) in order to avoid any risk of impacting ADSL.

And the benefit of this? We can buy the exact same product from lots of different providers who all increase their prices at once every year by the same amount like a cartel. Yay, or something.

A quick update - my ISP sent a BT guy out earlier this week and he confirmed that there are no specific problems on my line - it is just too far from the cabinet for anything better.

Apparently, we (me and the ISP) have 90 days to cancel but only if performance drops below 4.5 Mbs. BT seem to consider the performance acceptable.

Zen (the ISP) have been very good. They have arranged a call from BT which they have had to pay for as BT don't accept that there is problem. They have also been very good at responding to my emails and calls.

This is a very old thread now but I thought I ought to be fair to Openreach and update to say that they have been doing some work in this area (I have been told that they've been replacing aluminium cables but I have no direct evidence).

Anyway, whatever they have done, my typical speeds have increased significantly. In the middle of last year, they went up to around 13mps. Earlier this year it was 16 and the last month or so it's been a steady 17.5mbs.

That's plenty for what I mostly use.

think most unlikely they will be replacing cables - what exchange is this in the uk

how many extensions do you have and did you have a self install or managed install when you ordered FTTC and is it new property or old property

as all of these could impact the speed

If the fault rate for phones is high enough they will still do copper upgrades.

Did you ever establish your cabinet number, and if so has it changed?

It could be that you were given a half story from somewhere. It is possibly true, but maybe not the main reason.

What might make sense would be if a new or spur FTTC cabinet has been installed closer to you in order to comply over the medium term with the 10Mbps USO for BT in your area. With Zen and therefore you being spin-off beneficiaries. This could well be cheaper in this particular case for BT Group than rolling out FTTP at this point in time.

My broadband basic info/help site - www.robertos.me.uk. Domains, sites and mail hosting - Tsohost & Ionos.
Connection - Three B311 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up. 1+ 8 Pro max 80Mbps down, 24Mbps up.

It's Suckley, Cabinet 2 (Worcestershire). I doubt it's changed as, as far as I'm aware, there are only 2 cabinets, both outside the exchange, which is about 1mile from our property.

The exchange is Suckley (Worcs).
It's a 1960's property and I only have one extension socket but with nothing using it - we have DECT phones for extensions.

It was a self install but an Openreach guy came an checked it out afterwards as speeds were poor (6mbs) - he said nothing could be done, due to distance from exchange.

Have you compared the attenuation rates from back in 2015 compared to now as aluminium cable would have a higher attenuation rate.

No I haven't done that and didn't know where I'd find that info - but I found current in my router and it says:
Line attenuation: Receive Direction 39 dB, Send Direction. 16dB
I'm not sure if that's good or bad.

I'm afraid I don't have any historical info as I hadn't looked before (unless it would have been collected by tbbMeter, which I used to run until I got a Fritzbox router, which isn't supported). I might have the old info from that somewhere.

Thanks for that. I didn't think to look back at posts here.
Anyway, I've found some info in the weekly email reports from my Fritzbox (3490) - mid 2018 is the earliest I can find. See table below with some highlights. Results have been pretty consistent at 41/18. Unfortunately there's a gap between March and last week due to a change in ISP config where I forgot to update the email settings, so wasn't getting the emails. Unless I can find something between 2015 and 2018 on my old PC (currently offline pending a Windows update), I won't be able to check what happened in that period.

Thanks, I didn't know that - I haven't noticed any more cabinets but I haven't been out much recently! Is there a site that tells me where they are?

My Fritzbox report says the line length is 1524m, which sounds about right for the local exchange where I thought the cabinet was.

The BT availability checker says I'm on cabinet 2. It also says my VDSL line rate is (high) 13.4, which (as far as I recall) hasn't changed for years. Certainly I'm doing better than that now.
