Jake Black : I just gave this a thumbs up as I used this video as an example of how not to do a video for my production class. Thanks!
MrEthanhines : Will you PLEASE slow down! You don't have to rush to explain things.
DS : please remove background music annoying
Nanya Biznus : Please make a subtitle or type the speech on the description. Or do both. It would be great.
Cat Jax : I am really interested in getting the information in your video, and I can tell you know the info about which you speak. However, you remind me of my kids when they were going through their early to late teens-----you speak too fast, and it would be helpful to you and your listeners if you practiced enunciating your words. I am not ragging on you, nor is it my intention to be rude or critical to you on a personal level. I believe you have a lot to offer to those of us much less knowledgeable. You also brought to mind some fond memories about when my kids left messages on the "answering machine." We would sometimes have to replay it over and over, trying to understand what they were saying. So, I at least appreciate you making me (& my husband) laugh by remembering this very issue with our kids. I do not doubt that you will get better with experience. Don't let the rude, insulting people get to you----some people get mighty harsh when they can hide behind a keyboard and screen and NEVER let the really bad insults affect you.. Piece out and looking forward to watching as you progress with your videos.
How FTTC Works / VDSL
How FTTC/VDSL works and a quick look at UK Phone systems and basic broadband fault finding at the phone line level. This is a massively simplified setup but the principals still apply.
Please note, as I mention a few times you should NOT touch anything before and including the back plate of the master socket. Visually inspect everything, yes by all means. The ring voltage isn't enough to kill but it will sting, seriously, its not pleasant.
Max Lewis : First YouTube video to properly explain the full system rather than just drawing diagrams.
Geoff Roberts : So... this is what we in Australia call FTTN I think, Fibre to the Node (green box) which then puts the VDSL from fibre onto a number of customer analogue phone lines for the last 800m or so.
FTTC here is Fibre to the Curb, which means fibre runs along the street and has an individual node for each customer to their old analogue line, so the analogue run is only 10m or so, which makes for much better performance. I'm presently on FTTN because that's the only option here right now. I'm at the fringe of it in fact, if we were two houses further down, we'd only be offered wireless broadband. The raw linespeed varies a bit, but around 70mbps seems to be about all it can handle here, at shorter distances, speeds over 100mbps might be possible, but it's a lottery and depends how good the copper is. Phones are all VOIP now, the analogue phone network has been closed down in toto. So you either need a standalone IP phone or your analogue phone runs directly from the Phone port on the modem inside. I've got a 50mbps plan, most you can get is 100mbps but I can't have that because I'm too far from the node. They're promising at some point to expand the fibre network (which would be good because the copper lines are 80 years old and not exactly great for data). What comes into the house is a standard 2 pair phone line, minus the analogue phone service. Only one pair (blue/white) is live. Red/black is not (normally) used. What's bad is that if the power goes off, you lose both internet and your house phone as the FTTN cabinets don't have any form of battery backup. NBN (National Broadband Network) that are the national provider via Telco retailers, is something of a political football, the original concept was all fibre to the premises, but there was change of government and they stupidly decided to go with this mishmash because it was (they thought) going to be 'good enough' and supposedly cheaper. Now it's exploded in their faces and they are now admitting that the FTTN concept is flawed because a lot of copper is just too old to handle decent data rates AND there's still a lot of people in urban areas who are being forced onto wireless broadband which has its own issues. There is also a satellite option for isolated areas, (which there is a LOT of in Australia) where there is no phone service at all, or possibly just 3g/4g. 5G is just being rolled out in major cities. Going to be a while. The sat service is maximum of 50mbps, data is expensive and gets throttled if you go over the cap. There's a 650ms lag because of the geosync satellite hop. It seems we might see SpaceX's Starlink service here sometime this year, which I suspect will see a whole swarm of people ditch their NBN satellite or Wireless Broadband, probably even some FTTN users might go Starlink because of better speed. (Musk is guaranteeing 100mbps plus which would be better than what I've got). NBN is reacting by lowering the price of business satellite to try and compete, but it's not fixing the basic problems inherent in it (Far more people on Satellite than the government planned for because the phone network just doesn't cover enough of the country) The NBN is a national disgrace and should have gone ahead in the original fibre everywhere form, but it wasn't politically acceptable for the incoming government to allow something the enemy thought up, so they 'revised and improved' it by trashing the Fibre network concept and piggybacking the consumer end to extant analogue phone lines. This was clearly a HUGE mistake which they have now, very reluctantly admitted, but it's going to take a long time to remedy and the cost had blown out enormously even before then. For emergencies where the power is off, FTTN customers like me will lose both house phone and internet services (even if the exchange has power) and NBNs advice is 'keep a charged mobile handy' which is fine to a degree, however most of the 3G4G sites have only around 12 hours of battery backup, once that goes if the outage lasts long enough (last major one we had was 3 days a few years ago) you are reduced to UHF CB and/or smoke signals. We had no mobile service for about a week as the Telco's site we use didn't come back up when the power did and had to have the equipment replaced which took another few days. At the time, phones were still analogue, so they worked through out, but that's now dead and buried so any lengthy outage now will take out house phones and internet and leave you dependent on mobiles with around 12 hours or battery, unless you are with one provider (Telstra) who have a cell site at the exchange which has backup generators. Other providers (Optus et al) will be dead in the water after 12 hours or so of no power.
Alec Ver Bunker : I just found this channel today and I'm absolutely in love with it. I've been trying to figure out how to set up a network for a network of ski cabins that span almost 100 acres. We already have copper phone lines buried and I've been wanting to reuse them forever now currently no free WiFi at the cabins. If you keep uploading DSL videos I promise you'll always have a view . Maybe a video on how to set one of these systems up start to finish??
Carl Richards : Brings back memories with some of the equipment, used to work in as the supplier for CPE, HK612 and Call center G/S, LCGC, LS and DID
A : I've always wondered what all those wires were doing, thanks.
Quick look at a VDSL DSLAM
A breif look at a typical VDSL DSLAM setup. The bits you dont see
Rtech Lab : This video, for one of ours, has had a few hits. Would you like us to do a full setup and talk through the whole thing. Hosting provider to your home PC?
Michael M : So, so interesting- thanks! Love when things are demystified
RXP91 : Thanks for these videos, really useful. On my 3rd Open Reach appointment for a bridge tap, battery fault, RF interference and now another bridge tap so interesting to see why all these go wrong in crowded environments!
A1eR : Curious that you still use analog phone in combination with VDSL. In my country for VDSL contract they no longer gives you the analog line, but instead they give you voice service trough VOIP (in the modem/router they give you you have a couple of analog output, or you can use whatever VOIP phone you want in reality). It's probably way cheaper this way, since everything is VOIP and you just need to run fiber to the cabinets.
Also you avoid potential interferences with the line, especially with houses with multiple phone points. In fact it's advised to get the best signal to cut off every other phone point from your installation, and basically have the cable that comes into your home plugged into the modem.
J : Great Video, really helped me to understand what goes on beyond the household demark.
