Hi guys,

I am apologetic this is a first post but would really appreciate some understanding, I have checked the forums before posting this however no one has really put in the format I am about to which is something I am able to understand.

I have a few questions... Firstly what is the red/black cable coming in and why is the scotch lock on that red and smaller (I have cut this and replaced with the orange ones you see in the picture) is this problematic? After my mess up of a connection attempt I replaced it with an orange one and my download speeds have dipped right down to 9 mbps from 25 ish

Secondly, is this connection setup correct ( to get a better idea of how I am connecting ill explain my format)

So my format will be like so Colour1/Colour2 connects to Colour1/Colour2

The setup I had tried was...

Orange/White( "line" from filter) to Red/Black (black cable going into demarc)

Blue/white (from black cable going into demarc) to Blue/White (to "phone" on filter)

Green/white ( from filter ) to Green/white ( from Cat5e cable going into house )

Would the correct setup infact be

Orange/white ("Line " from filter) to Blue/white (black cable going into demarc )

blue/white ("phone" from filter ) to blue/white (cat5e into house)

green/white ("DSL" from filter ) to green/white (Cat5e into house)

if i am 100% wrong in both please let me know :( I know my VDSL speeds should be far better than 25mbs down 3.6 mbps up as my house is not that far from the exchange.

Thank you VERY much in advance for any possible help.

Daniel

Did you have a working connection before?

Option 1 must be wrong, you don't have 2 connections to the incoming cable.

Option 2 depends on your phone wiring. There is also the existing white cable. The blue may be direct to your data jack.

At this point I think you will need to open up and inspect your inside jack points to confirm exactly what color pairs are being used.

I suspect you will find that your VDSL jack point has the blue/white pair of the cat5e cable connected - in this case connect the blue/white pair of the cat5 to the green/white pair out of the filter.

I also suspect your phone jack will have the blue/white pair from the grey cable connected - in this case connect that blue/white pair of the grey cable to the blue/white from the filter.

Now your incoming line. It looks the the red/black pair is connected together - if this is how you found it, leave it as that is the unused spare pair in the cable. The other pair (blue/white?) in the black cable connects to the orange/white from the filter.

As to speed, I'm not an expert here but reading other posts suggests that DLM could drop your line speed back after several disconnects and it will just take a while (days) for the speed to ramp yup again.

Hope this helps, good on you for having a go at doing it yourself!

The black cable with blue/white + red/black is the lead-in. It a appears your service comes in on the blue/white pair, so red/black unused and jumpered together.

Orange pair of splitter will go to blue/white of lead-in.

Green pair of splitter will go to green pair of CAT5e/6 cable. At other end of that CAT5e/6 cable the green pair will punch down on the blue pair of an RJ45 socket. This is your VDSL jack-point

The blue pair of splitter will go to blue pair of CAT5e/6 cable and any other existing POTs cabling. How this is done really depends on the rest of your wiring so can't advise on this without seeing it.

Thank you all very much for replying.

Just to confirm one last thing sorry Coffeebaron. "Green pair of splitter will go to green pair of CAT5e/6 cable. At other end of that CAT5e/6 cable the green pair will punch down on the blue pair of an RJ45 socket. This is your VDSL jack-point" the bold part - so on the back of the jackpoitn where the blue/white cable is already punched down, in the same "punch down area " i guess to call it... punch the green/white ONTOP of it so they are both sharing the same punchdown holder? or would I be using the other available "punch down areas" ?

No, do not punch down green & blue pairs on same jack point. Green pair on its own separate jack point.

Thanks Coffeebaron!! The upload has doubled from 4mbps to 8.64 and download I imagine needs to be reset by DLM as it used to be around 25-30mbps (is that right? ) .... I have seen the wiring the electrician has done now. He grabbed the main line coming in and tagged the blue/white cables to a whole batch of other blue/whites on other ethernet cables around the house. He has also wired up the green/white to each jackpoint. Since i've taken the green/white from the main cable and plugged it straight into the jackpoint by itself where the modem connects, there's no need to go around the house and remove all the green/whites as they shouldn't interfere correct?

Don't let that electrician touch your data cabling again - that wiring demonstrates a complete lack of understanding/knowledge about data cabling.

As it stands, you should be getting far better performance already, and you can leave it at that if you want to. In an ideal situation, all those ethernet cables would be terminated on a patch panel in the location they all come back to, so that phone/data/whatever can be sent to any given location in the house.

It's kind of horrific.... should I take a picture for a laugh? The main line coming in he only has the blue/white paired up to the rest, and all the other colours wrapped around the cable doing nothing.... But he wired up everysingle colour at each jackpoint lol. I always figured he was a cowboy based on how the internet performed and the jackpoints that did and didnt work. Getting an understanding and seeing it for myself just shows me how bad it was.

Go on, post a photo! In an ideal instal, each jackpoint should have an RJ45 cat5e / cat6 socket (depending on cable used), and the other end should be punched down into similar patch panel, where there would be room for a router / switch / ATA etc. Connecting all the blue pairs together will deliver an analogue phone service to each jack, but that's it. It will also create multiple reflections off the ends of each of those branch cables which plays absolute havoc with xDSL frequencies on a cable.

Here it is!

First picture is of the green/white i've done straight to the demarc.. (if i am wrong to leave as is tell me so)

hopefully they give you a clear picture of what he's done... it's hard to take pictures as its quite dark up there. But essentially from that mess of blue/white cables all connected, they are connected from separate ethernet cables (tagging onto only the blue/white) then if you trace those cables connected to the blue and white onto the jackpoints, where EVERYTHING is connected lol...

WTF

Never let electricians do data cabling. Since you've got all that cable I'd recommend installing a patch panel and using it to its full potential as that is such a waste. Your master filter installation job looks fine too so good job fixing that up.

What sort of jackpoints do you have? All four pairs should be connected at every jackpoint (to their respective contacts, not to each other!).

Lol I was just a little boy - this was 10 years ago, my parents just hired whoever they could afford sadly and that's what they got. A patch panel is a good idea :) All the jackpoints in the house are RJ45 jacks.

RJ45 jacks should have all four pairs connected, assuming the cable twist is continued up to where it's punched down. If you got around to installing a patch panel at the other end, you'd probably have a fairly reasonable system.
