Consumers adopting one of Openreach’s 80Mbps Fibre-to-the-Cabinet (FTTC / VDSL2) based UK broadband ISP lines (usually advertised with average speeds of c.60-65Mbps) are likely to create fewer fault reports during the initial provision phase after the new “low level error correction” feature began being applied to them.
The roll-out of this feature actually began back in February 2018 (here), although at the time it was only deployed to the operator’s slower 40Mbps and 55Mbps product tiers (this wasn’t stated in their public briefing). This week it also began being extended to their top 80Mbps product tier on the same VDSL2 based broadband service.
Normally a Dynamic Line Management (DLM) system is used to control the speed and stability of these lines (your speed may go up or down depending upon how stable DLM thinks the line is), but after first provision (i.e. new installation) it usually takes about 48 hours before this is introduced so that everything can be correctly calibrated. As such new lines go through a period with no error correction being applied and their speed capped.
As Openreach explains, “This can lead to customer(s) raising faults before DLM starts working due to excessive data errors which impact their broadband service.” The solution that they’ve developed is to temporarily apply a low level of error correction during the first 48 hours, before DLM kicks in properly, which helps to mitigate the aforementioned problems.
Surely fttc employs copper to the house and if you have a dodgy bit of copper or raine interference in your house DOM will slow the line speed particularly on longer fttc lines.
Its does but thats a different thing. There are distance related speed issues and intermittant issues.
Dynamic Line Management System is a hell evil – scrap it or disabled it OFF for the better for us all.
This just goes to show how nice FTTP is. You pay for a Gbit. You get a Gbit. No line management. No upto speed service. You get full speed no matter you distance.
Yes total agree with this.
Yes, is nice but sometimes the only that you have is FTTC. I’m paying talkttalk 76 but won’t g
have more than 50 Mb/s.
Just when I thought I was done with all the bollocks copper gives you and started enjoying my 100+ mbps stable speeds, I’m moving from a FTTP place to a FTTC one, bummer.
Well, you’ve a maximum speed of a gig. You’re more at the whim of network capacity so may come in lower.
Cable is the same kinda thing, distance not really an issue.
Wonder how many people on 1G actually see those speeds and consume them with any regularity? B4RN users are all on a gig yet the average usage is at most in the ball park of Openreach FTTC due to user mix.
The only gigabit service I know of with any scale quotes 900Mb average. Sweet, but not quite a perfect 1G.
Average speeds are generally very misleading as it usually makes no account for poor internal wiring/networking which is exacerbated with higher speeds.
@Tim that’s right. FTTP is a necessity especially for high rise buildings where line distance is a factor that affects speeds, reliability and noise margins. Can you imagine how slow the speed would be at One Canada Square building in Canary Wharf with just FTTC alone? It’s impossible to get 80-100Mbps with FTTC at 235 meters tall building from cabinet, unless of-course that green cabinet is installed right next to the office building which still does not guarantee receiving those speeds at the top floors of the building.
FTTC copper handicaps fibre speeds. Think of it this way Copper=Pentium 4/Celeron Processor and Fibre=Nvidia GTX 1080 Ti. LOL as we know PC builders know this will create a bottleneck! You won’t get the full juice of the GPU with a weak CPU. That’s the same with Copper and Fibre!
At least in the case of those I know of average speeds come from kit hard wired into ISP routers and monitor wireless and wired activity to try and ensure they provide a fair test.
Going forward testing is being incorporated into the ISP routers themselves.
Average speeds should be pretty representative of user experience, which is the point.
BT support told me that the router should stay on all the time to force the DLM to think that the line is not at fault, although it is me who likes to save energy by turing it off when not needed.
There’s a useful energy usage comparison here https://www.ispreview.co.uk/index.php/2017/01/energy-usage-uk-home-broadband-routers-big-isps-compared.html/2 . I’m with you on wanting to turn it off every night just on principle, plus millions of watts consumed every year by all the ISP’s combined. But at the same time I don’t want to give dlm an excuse to lower my speed.
I also used to do this before. But from around a year I stopped turning off the router. It is basically an illusion that you save a lot of money by turning off the router. In reality the calculation of a router staying on 24/7 will only amount to roughly £5 a year, which is absolutely nothing considering the hassle you go through of having to turn it on every time and waiting 2 minutes or so for the connection to return back on.
By the way, if you turn the router off and on you cannot track how stable your line is. You need to be able to tell how many days or so your internet can stay on without drop-outs. Only by leaving the router on and viewing your router stats can you tell how stable your connection is and compare that to whichever other ISP’s you had so you can tell which is the more reliable ISP.
DLM for the first 10 days needs the router remaining on. Disrupting this process will lead to a lower speed as DLM will think your line is unstable even if it is stable at the higher connection speeds.
Until we don’t get FTTP and are on basic ADSL2/VDSL2 (DLM) turning off the router won’t be wise.
costs less than 22 pond a year to run a router 24/7. hub 2 on adsl was 11 a year. its really not worth turning it off ever. dont blame anyone for your own mistakes.
Please please please buy a decent Router not the ones supplied by your isps they are usually of a low quality and reliability if you have to have fttc not fttp then a router that has a Broadcom chipset like the Billion bipac
Gregory it’s rein not raine get your vernacular right
Cheers thanks for that my mistake but it can still be a pain on a long line with 1 meg on adsl2
Meanwhile we get fec’s in the cabinet itself lol!
