[1] internet cable installation, MDF Jumper
the GPO over here used to use similar looking cable to speaker cable as dropwire, godawful stuff, copper clad steel, it tends to rust out at any nick and cause VDSL drops intermittently
There was a cable similar in this video but I cut it out. I swear it was thin like a 2 pair but when I manually traced it.....it seemed to be thicker on the other side and jammed into a hole with other electrical.
Gotta love when all you get is 50Hz buzz.... frustrating a/f , or bleedthrough and you can't find the pair because they all warble at you lol
omfg yes! so frustrating. I have another probe that it supposed to filter out the 50/60Hz hum but it doesn't really do such a great job.
Happy new year to you from the UK :)
Thank you :D Happy new year to you too :)
nothing sus in that shop, the glass sculptures and the box cream whip gas, was it a cash job by any chance
hahaha. Yeah it was kind weird. But no, it wasn't cash. Job was through their ISP. If it was cash, it probably would be more promises rather than actual payment.
vape/weed shop. i'm FTTN, took 3 ISP's to get one that would push through the request to NBN to replace my line to the pillar. Would always fail on a friday, and no support until monday.. since the 10 pair was replaced, been solid for the last 5 years. my unknowing neighbours got the benifit of my suffering -
you're not in unanderra nsw are you? i could swear I was in that roof 2 months ago...
At least its cable tied. lol
I'm waiting to see some cabling hot-glued to something. :P 🤣
Welcome to the world of commercial cabling where someone did something in 1970 so everyone else follows suit
🤣🤣
Interesting so rather than it being one unit with 4 outputs it's 4 discrete units in one case. Weird design decision, although on the upside it means if one customer does something stupid it doesn't affect the others.

I had DSL service in Wayne, NJ and it was sporadic at best. SInce I worked for Verizon in NY when I called in the trouble NJ Bell sent a tech out and he did clear a bridge tap. That made a small improvement on his test set. He provided me with a Whole House DSL filter to use in place of the individual filters placed in the home. I installed it in the garage where the POTS Line came in and ran a Cat 5 cable up to where the ADSL Modem / Router was. Service improved immensely and we no had dropped internet signals.
What we do in the states is one on a wire and one on ground.. works great..
Interesting video, I had no idea FTTC could operate with reverse power. It seems an odd solution to run fibre so close to the house then do DSL to just 4 properties, rather than just taking the fibre that little bit further for FTTP. That said it does at least mean less crosstalk and attenuation compared to the UK solution where they used street cabinets to serve 64+ properties, with a vastly varying sync rate depending on how long your line is and how many other customers causing crosstalk in the cable bundle.
Thx for the comment :) Yes it's defintely an odd solution. I feel as though it was just a cheaper option. Lots of buildings are now getting free upgrades to FTTP if they've already got FTTC. So it could very easily have been FTTP from the beginning. I agree on the less crosstalk and attenuation. I think it also depends on location too as not all houses have a pit close by. One house might be close to the pit and have 20m of copper but the next house will likely have 30-40m an so-on.
@@CommsGuy As someone who has FTTC and (because of past faults) knows where the DPU is and exactly how the cable gets from there to the phone socket in my apartment, I can see why FTTC would be easier and cheaper to install (no need to have to come into individual apartments and install FTTP equipment, no need to somehow fish cables through the walls etc). It also means not needing to deal with landlords/owners in the case of rentals.
Here in British Columbia (western Canada) most of the urban areas had ADSL from 2000 onward. Originally up to 1.5 Mbps then later up to 6 Mbps. They overlaid the copper network with VDSL2 in 2010/2011, which offered up to 75 Mbps (150 using two pairs) I guess this would be classified as FTTN, and they are powered via ±190VDC over many pairs back to the central office. I believe much of the equipment is Alcatel-Lucent 7330 ISAM. In 2017 they started building a new FTTP network. Most urban areas now have fibre but its far less common in rural areas. Originally just GPON but they've also been deploying XGS-PON for the faster tiers Most of the outlying areas around my city are still only served by ADSL (6 Mbps theoretical, 2-4 Mbps actual) I had to install a wireless bridge over several km to get usable internet to my CEO's house. Fortunately it seems that this year they've started hanging fibre in a few of the rural / farmland areas, so with luck we will get it here in 2-3 years.
These mdfs are still so common in older setups, should see older shopping centres . You CAN work on it and while is standard now it was back in the day . Easiest way is to scotch lock instead of using the screw terminals
Yeah, if I could go back in time.....I would have just done it.
currently watching the short then glares at my server rack knowing the cable mess is just as bad
hahaha, happens to all of us :P
If I was in your position, I'd check the box outside first too. It takes a minute and can save having to go into the house.
Thank you. Finally someone that agrees :D I started checking it first after being on a job and fumbling around checking sockets and finding nothing wrong, check ceiling space.......nothing wrong. Finally found an outside box and BAM! that was the problem. Didn't help that the home owner had painted it the same colour as the wall & it was under the eaves. If you didn't know it was there, you'd never see it. It blended in so well.
I am so happy I got FTTP now so none of this nonsense.
I have to wonder how connections like these ever worked at all. It almost seems like DSL connections degrade over time. I get the feeling this person's FTTC worked for a bit and just eventually died, despite nothing changing in the premises? Had a client in the Inner West who somehow ran their business on a DSL line, but eventually it was so slow (2mbps downstream sync) to the point of being unusable. I'm not sure how they ever functioned to begin with. They ended up being sold 4G modems, which were hardly much better (contrary to what Optus' sales reps promised), and the internet would drop out more in the afternoons due to the low-flying planes overhead!
From what I'm told by the customer, it never worked well at all. Sometimes they'd get connection but it would constantly drop out so they'd move the NTD to a downstairs socket but wouldn't get any improvement. Apparently a few days before I went, it had just completely stopped altogether. I'm not a fan of sales reps. Too many times people have been promised great speed/performance but they never get it because sales don't actually understand any of the tech side and only go by specs/paperwork. I see that all the time.
These can sometimes work at low speeds for a little while before dying completely. It's not that they degrade, it is more network upgrades at the other end of the copper, be it hardware or software, can make it more sensitive to wiring issues, which can make or break the connection completely. Copper does degrade over time, but it takes many years for copper and insulation to degrade to a point where it is no longer usable. Usually it is the insulation that breaks down
@@EsotericArctos Yep makes sense. That’s why it confuses me - the cabling wouldn’t degrade so fast (if at all) that it should affect anything in such a short span of time (with most people probably only getting switched over to NBN within the past decade or so). So ergo me wondering, what does cause it to go from working atleast well enough for people to not complain, to it working poorly enough that they do, or outright not even working at all. You’re probably right, if it’s because of changes elsewhere on the infrastructure. Though, the point of FTTN/FTTC is to make the copper shorter and shorter, so .. Not much changes there? Weird.
@@rakeau Another reason is the type of cabling. The old copper lines were CAT3 and installed for Voice only. Then came DSL which wouldn't usually exceed the 10Mbit rating of CAT3 cables. Then NBN came along and started pushing 50 to 100 Mbit down those same cables. So I believe it's the speed and the frequency as well as the bandwidth of the cables which cause more problems than decades ago when it was just pure Voice lines.
@@CommsGuy Yeah ofcourse. Would just think that, if it worked in some capacity (eg if you were getting say, steady 20mbit) then it shouldn’t just drop to 10, then 5, then 2, then 0 after just a couple years with no physical changes to the cabling. But, I dunno it just seems to happen.
To my understanding of FTTC is that the DPU in the street is connected parallel with the exchange for co-existence with ADSL so when the customer is ready to order an NBN service their old internet will remain active until the NCD arrives. When the customer connects the NCD to their line it will power a relay in the DPU disconnecting the line from the exchange.
Yes I have heard the same. One customer had that very experience where for the new connection to be active, there would have to be data flowing to initiate the changeover. Sounded weird to me.......how can data flow to change over the connection if the connection isn't fully active. But I get it now.
Congratulations! Im a telecoms engineer in the UK for the railway and previously British telecom. It is good to see the similarities in the networks and your methodical fault finding
Thank you :)
i am amazed they make you (aka th customer) do this down under... here in pommie land there is a clear demarcation point... altho copper is dying here
Yeah there IS a demarc, which is the MDF, but so many go either beyond the boundary (which they shouldn't) or just barely get to the boundary. Seems to fall on how lazy the installer is. hahahaha.
Thats not in a bad place compared to some I had to work on in the UK.
ah you too had to deal with 'theres some old british telecom shit in the boiler cupboard' >
'finds actual pabx behind a newly fitted water cylinder
I wonder if that double punch was a remnant from before DSL you know analog phone where they wanted the same line in two different spaces. Although it was a bit hard to follow what was going on. That's why it's definitely worth taking a little time to investigate what's going on. Fibers where it's going but there's definitely a lot to be liked about copper.
Yeah I love the copper. So much easier to work out where lines are and where they're going. As well as tracing with tone and probe devices. The double punch definitely would have been from the analog phone days and probably would have potentially made a "bride tap" issue as well. Sorry if it was hard to follow. On this particular job there were a lot of people I had to cut out and it can be hard to make commentary while thinking about whats going on & talking with the customer etc...
10:00 yes it is it's not over a toilet or something like that.
omg I can't imagine if it were.......
Next time a PoE camera install I hope
Hopefully yes. That would have been a lot better to have cat6 on this one. Thx for watching :)
@@CommsGuy Thanks for the great video again! Love your NBN video's. Back in the day i had a summer job, cabling end testing DSLAMs at MDF in central hub locations of the national provider here. Now i'm a expert network designer at the biggest cable provider in NL.
@@svdleer That sounds like a cool job. Thanks, I'm really trying to get more work involving NBN as I really enjoy fixing their issues :P :)
Well copper lines in the UK will be retired by 2027. Our PSTN and ISDN will be shut down by 2025.
:(
@@CommsGuynot sure why anyone would miss the old system. It was painfully slow
what's with those RJ45 terminations? lol
This ones in the Cisco device? I've no idea. I presume some telephones but who knows with this place :P
Great video mate, keep it up!
Thank you :D
Reason for the phone system next to the IDF is due to old telephone lines and or digital phones. Nice video, it's good to watch other people go through the same pain :D
I thought as much. Just a weird spot to put it. Also this is an MDF not an IDF so it makes it stranger to me. Especially since this was a small centre with multiple shops.....so who is the ipecs system for?! Can't wait for someone to get angry with old equipment and disconnect it. :P
@@CommsGuy then find out it has one line still active, doing an ever so vital alarm circuit everyone forgot about ;)
MANY years ago (embarassingly many, think 80s) I cut a dead alarm cable on a demolition site at the university I worked for... 20 mins later the fire brigade turned up to put out the fire in the building that wasn't there anymore.... I didn't get in trouble, maintenance control, were supposed to have disconnected (in software) that alarm. Someone hadn't
So much for TCA1 Form.
🤣🤣 Wow, i thought I was the only one who knew about TCA forms!!! lol :P
@@CommsGuy Yes its part of the legislative requirement. Also there is a TCA2 form which is attached to TCA1. TCA2 form is for registered cablers to alert customers or building manager for any non compliant cable installations that are outside the contracted scope of work. Times have changed, no one gives a shit anymore they don't bother. I just kept them for backup into my report for just in case scenario. One tip take plenty of pictures. Now I will go and enjoy my retirement and tell ACMA and registered cables authorities to get fucked.
@@rubhern8187 I write them up with both the TCA1 and TCA2 but you're right that no-one gives a shit. People mostly just throw it away one you leave. It's really just for covering your own ass these days.
so much for standards and cabling licenses and yet have seen so much crap out there go and figure. i suppose thats why i never renewed my open cabling license. why give out money to some bureaucratic bastards. Been unemployed for over 1 year and 20 years experience in Systems and Telecommunication i have seen refugee freeloader with work visa doing the most horrendously terminations in fibre and copper. that goes as well to sparkies and their fn etu union. There are not many honest reliable technicians. Some complaining how much they get paid and saying its not worth fixing. Well if you are not gonna fix it dont complain when they get their resources overseas. So go and complain to your fn union bitching and crying. Comms guy you get my subs and thumbs up
Thank you. You've hit the nail right on the head there and don't even get me started on those damn electricians. The amount of garbage work I see from them is unimaginable. I remember talking with one of them who was doing MDF jumpering and literally told me that he "doesn't know anything about telecommunications". I think I was paralyzed with rage after hearing that. In one of my previous videos (CCTV) I got mad because the customer talked about me on the phone and called me an electrician....words hurt. :P You are right of course with the horrendous work from people, I have so many mind blowing stories about that kinda stuff. Thanks for the sub and the thumbs up. :D
Defantly not worth losing a license over, not to mention the headache sorting out that bundle of mess as well.
Thank you. I got a lot of crap and lost further work from the ISP for not doing it. Good to have someone agree with me :D 👍 I went back to the site and had a sneaky look. Someone had cut a large section out of the side to put conduit through. Personally, I would have gone from underneath as there was more than enough space to get conduit into the box.
@@CommsGuy They were probably just looking for the lowest effort option and went through the side, anywhere else was probably too much effort.
@@ERGTZ Agreed. I'd rather do more hours than I charge for and make it good and long lasting than to do that kind of work.
Genuinely curious why there is so many pairs? Was it a duplex or something?
Thx for asking. No it was a house that had 5 or 6 phone sockets on the one incoming pair.
Wow, I haven't seen anything like that in a while as my house has had fiber since the dawn of it. Our MPOEs look a bit different than the american ones over here in the UK
My house hasn't got fibre yet from the open reach network so still common to see this. Luckily an independent has sprung up giving fttp. Alot of the problem Is all our utilities are in the ground so the cost to upgrade is expensive.
Scotchies. We call them jelly crimps in the U.K 😊
Hehehe, cool. The full name of them here is "ScotchLock" but I just like to call them Scotchies. :P :) It's cool that someone in the UK has watched this video, thankyou :D
RUclips won't let me post what I call them 😉 also in the uk
@@nakchAk Hahaha, Fair enough.
Be careful as you can see the customers external ip in the video.
ah damn. I didn't realize when editing. Thanks for pointing it out.
@@CommsGuy no worries it's not super readable but I think if I tried hard enough I could probably interpret it.
Not much somebody could do with it anyway.
Fan bloody tastic! I'm going to make up an RJ45 with exposed leads now so i can test sockets using 1 wire without removing them to connect to the wires. I always thought you needed two as well.
Awesome! I did the same thing. In fact I've made 2. I'd encourage anyone to make 2 as well, 1 RJ45 with all 8 wires crimped so you can choose any 8 wires for your tone but also an RJ11 plug with 2 wires so you can test phone sockets as well. :D
@@CommsGuy Yeh. Good idea re: the RJ11. I HATE trying to trace ports when something is already connected to them. Nothing worse than using the RJ11 connector on the keystone and asking "What's on the end of this? Oh, it's bloody active!" BEEEEEEEEEEEEEEEEPPPPP. Now i can whistle it out with 1 wire! Good onya! :)
@@lloydsshednanigans Yeah it's absolutely changed my site visits now. Previously if the other end was connected to a PC or switch then the CZ100 would beep indicating a short circuit but just using 1 wire now.....is perfect.
@@CommsGuy I'm semi-retired now but there's one larger job that I've been putting-off because almost every patch-panel port has something on it and it's a bugger to trace. I might use this method and re-map the entire thing.
@@lloydsshednanigans Excellent. Sounds like it would work with that scenario. Best of luck with it :D
Wow, what a rat's nest that was. Great you fixed it for the chap.
Yes it really was. Not sure if it shows in the video but I believe I left it neat and with all cables neatly routed in the box in-case they want to use a different socket in the future. Thanks for watching and commenting :D
What are the dsl testers worth? I used to be able to diagnose an adsl service by listening to the phone. NBN changed all that-
Oh yeah, test adsl was easy. Listen for dialtone :P This dsl tester was about $600AUD. Which believe it or not.....was cheap, compared to other testers. It is a good tool, but can be confusing to use. I'm planning to get a different one with a large colour screen, if I do then I'll probably make a video on it too :) Thanks for watching and commenting :D
@@CommsGuy maybe a demo of your current one? Can it test the copper side of fttc? I fix computers for a living and diagnosing internet issues is a major part of my work - I'm fairly good at skipping the "have you done x" part of the phonecall to the customers provider and going straight to get a tech out/replacement device needed part of the call.
@@voltare2amstereo hehe, it's great but also annoying when you've already done the ISP checklist before calling them :P I've never tried the DSL tester with FTTC, only FTTN. I believe FTTC is still VDSL2 so I guess it would probably work.
Never thought of using a clamp to hold a ladder, smart
Hehe, yeah it was kinda dodgy. But it was only to stop the ladder from sliding away while I was on the other end of the roof. Mainly because I was working alone.
That's so lazy. Definitely done by someone that doesn't care. probably sparky or IT guy.
You are not a comms guy. You know nothing.
Based on your comment, I'd say someone is playing keep away with your intelligence. 💩💩🖕🖕
Looks like all external DP's pre 1980s Till the krone idc DP's in 85
Yep that 50 volts DC will get you every time.
50 volts DC, or 70 volts AC of ringing current.
Don't worry, as it is old phone lines.
In the states its known usually as the arlington lv-1 (also lv-2 for 2 gang) Were only allowed to use them here for low voltage voice/data/video alarm and thermostat wire. Closed back versions are available which allow the fire rating required for 120/240 and beyond connections. Jonard makes a nifty 1 and 2 gang template with 2 plane level built in.
Thx for commenting :) Sounds like they're common in the US. I can see why, I think they're great!

Faceplate for a Cat6 socket. Video was only for showing the mounting bracket because it's very rare in my country.
