Hi, sorry if these questions have already been asked, I've searched through forum and i know there are already a handful of threads asking about basic VDSL questions but i'm still confused about it after reading them.

The Chorus guy will install a Splitter (master filter) in the ETP, which is connected to the line coming from street, but before the line goes to the jack-points in the house. The phone side of splitter will then connect to the existing feed to the jack-points.

He will then run a new cable from the xDSL side of the splitter to a new dedicated xDSL jack-point for your modem only to plug in.

So the length of this xDSL cable would be ideally as short as possible to not affect connection performance which would make installing the VDSL jack upstairs a bad idea?

If what i understand is correct, than the below method may be a good networking solution if i don't want to use wifi or have long ethernet cables running around the house?

Well the blue ethernet cables clearly state that they're CAT5e cables which is a good thing.

Judging from how there's individual cables with labels for each phone jack in the house, i'm going to assume that this is a star wiring instead of daisychain setup.

Using 2 of the 3 remaining pairs of wires from the Ethernet cable i should be able to have Fast Ethernet 100baseT

I should be able to ask the Chorus techinician to install the jack next to the home distribution panel inside the garage and connect ethernet cables from the router to the data hub panel at the bottom right.

The refferance to haveing the Master Filter/Splitter in the ETP and then running a new CAt5e or better applies directly to those that have legacy phone wireing (what would have been considered normal wireing with BT phone jacks from the 80s, 90s and even 00s and was often wired in series around the jkpts and not star wired)

In your case you have semi structured wireing with a HUB or stair point connection with Cat5e cableing and apears to be star wired

In your place the splitter could be installed in your HUB on the end of the Cat5 comeing from your ETP and not @ the ETP if required (no additional cables neeed to be run)
- even with star wireing a spliter is required to seperate the additional cableing off the xDSL circuit.

Yes they could/should install the RJ45 Jack for your xDSL Router to be pluged into in or near your HUB

Yes you can use two of the three spare pairs in your exisiting cables to create a 10/100 network connections from the HUB and distribute the connections from the Router to your PC etc

Unfinished? That is a finished electricians panel right there :)

Can i use 3 pairs? Faster than 2 pairs, i read you can't get gigabit ethernet without 4 pairs and 1/2 pair would give 10/100 right?

Don't go splitting pairs - it's a kludge at best.

If you absolutely need another outlet where there is only one currently, use a proper pair of splitters plugged in at each end.

Oh, did I mention to not split pairs ;-)

Modem should live in patch panel area. Fully patched RJ45 feeds from there.

The plan is to have my Draytek 130 and TP-Link 1043ND next to the panel in bridge mode with the 4 Ethernet ports from the router connected to the data hub which would be linked to 4 ports in the house.

Sorry could you explain a bit more about what you mean by splitting pairs? Do you mean that the idea in the article where you use 1 pair for phone and 2 pair for Fast Ethernet with 2 jacks isn't a good idea?

If you have RJ45 Jacks on both ends of the cable (all 4 pairs connected) then you can use plug in spliters at either end to give you differnt combination of use (2 x 10/100, 1 phone and 1 x 10/100, 2 phone, 3 phone or 4 phone)

10/100 requires 2 pairs (preferably orange and green prs first then blue & Brown Prs if required) / 1000 requires all 4

and what ever you do dont use the third pair (with 1 used for phone and two for data) and combine with an other third pair in a parallel cable to try and make another data circuit :-)

I feel more confused 0_0...

I currently have single RJ11 Jacks in the wall plates int he house and i plan on getting a double socket wall plate as well as RJ45 Jacks, the RJ11 will remain as they're connected to 1 pair (Blue， Blue/White) while the RJ45 will carry ethernet connections with 2 pairs(Does 3 pair work? Or you saying 3 pair is bad but 2 pair is ok?).

Btw, would i be connect a power board to the power socket inside the panel to power my modem and router? The white box connected to is used for the TV cables right? What is it used for?

Each blue ethernet cable has 4 twisted pairs. All 4 pairs should be connected to a single RJ45 outlet at each end (patch panel and outlet).

You can then use that cable for whatever service is needed. If you need to run a phone and 100BaseT from a single outlet, then use the correct splitters at each end.

If some pairs are pulled off the RJ11s for phones, then it hasn't been wired correctly.

Yes, you can have a power board in there - just make sure there is a bit of room for airflow if you start putting lots in the cabinet.

White box may be a TV RF amplifier.

In my case right now these blue ethernet cables are only used to carry the phone and adsl and only the blue and blue/white pair or wires are connect at both the panel and the rj11 jacks where the other 6 wires are left unconnected, does that mean they were wrong to start with...?

Thats Ok - as you are probaly already aware your cableing appears to have been wired for dedicated phone use only with one pair connected (blue&blue/white) and 3 spare pairs in each cable (except for the one or two cables that appear to have to have 2 of the other pairs attached to a rj45 to terminal block in your hub)

A sugestion is to convert your cableing to non-dedicated structured wireing both ends of the cable terminated on RJ45s (all 4 pairs terminated) and to make multipule use of a single jkpt, addaptor plugs are used, which are commonly refered to as spliters (Not to be confused with a master spliter), to break out the pairs for seperate use if required or you can use a jkpt for data (1000) and another for a phone.

If you want to keep your existing RJ11s and just add RJ45s for data (10/100) then you never terminate the third pair (Brown&Brown/white)
