I'm wiring for LAN, and I need to do some landline phone rewiring too. I've got tons of CAT6 solid core, so can I use that for phone with standard phone jacks?

Also, I'm wondering if I should have anything at the point where the phone line initially enters the house.

In the past, when we've had broadband issues, the telco companies have recommended the installation of some device (I can't remember much, so I have no idea what to search) to boost the signal. Some kind of splitter/amplifier that divides the line into one for just phones, and one to go straight to the ADSL modem... Does anyone know what I'm talking about?

Cat5e works fine. But using BT jacks is rather pointless when RJ45 jacks are so much cheaper and flexible since you can use them for data and/or phone.

You're probably meaning a master ADSL splitter. These deliver seperios DSL performance compared to plug in filters and mean you no longer need plug in filters.

What, do I use a RJ45 to phone adaptor lead then?

Yeah, any recommendations?

Most likely the input on your phone will be RJ11 so just get a RJ45 to RJ11 Cable from the likes of Jaycar or make one yourself out of Cat6

There is only one certified master splitter so there aren't too many recommendations! All new models are VDSL2 rated, the older ones were ADSL/ADSL2+ only

Is this the kind of master splitter I'm after?:

(says telepermitted)

There is no master splitter that amplifies, is there?

Yip.

No such thing as an "amplifier" for phone lines.

What is a plug they use for phone line in on ADSL modems? Is it RJ-11, 12, or 14? Will it take CAT6?

Either RJ-11 or RJ-12 for the modem end, it doesn't matter.

Exact same size connector with 6 pins, just RJ-11 typically only terminates 2-4 pins/wires, RJ-12 terminates all 6. ADSL only uses 2 pins so it's all good with either.

3M RJ-12 to RJ-45 cable, product code: C-RJ1245-2
http://www.cablesdirect.co.nz/www/pdfs/scs74.pdf

Just search for C-RJ1245-2 on www.cablesdirect.co.nz and add to cart etc to order.

DSE and Jaycar sell a similar cable too if you want to buy instore.

Don't try and hack RJ11/RJ12 plugs onto cat5e or cat6 cable. Use a RJ45 crimp plug, a joiner, and a RJ45 to RJ11/RJ12 using 4/6 core cable.

Not sure what you mean "can it take Cat6", but you don't want to use solid cable to make patch leads and you would certainly make a mess trying to put 4-wire RJ11 plugs onto 8-wire cable. Use a modem lead like this, I can send you one if you like.

You master filter should connect its phone side to a patch panel that allows you to patch several/any jackpoints to the phone line. Telecom side of the master filter should either go to a test point thats patched to a single outlet on the incoming line, or just get spliced to the incoming line itself with some gel-crimps. It sounded like you hadn't got that far.

Time to find a new industry!

Thanks for the help so far.

I just got the master filter, and I'm a bit confused...

[IMG]https://i.imgur.com/Tu3re.jpg[/IMG]

So it's clear which PAIR of wires goes to what, but what about the individual wires? Starting with the line in, I have four wires coming from outside:

Yellow
Black
White
Brown

Yellow and black are the only ones connected ATM, so I'm guessing that the white and brown are for a second line, so I'm ignoring them.

So, what I need to know is which wire from the Orange/White pair goes to Yellow and which goes to Black?

Same for the modem and phone outs; all modem and phone leads consist of a Red and green Wire. Which of these goes to the white wires from the splitter?

Also, is there any reason why I shouldn't install the master splitter in the telecom termination box where the outdoor wiring connects to the indoor wiring? It fits perfectly, and they say to install the splitter as close to the entry point as possible...

Hi, no there is no real reason to put it in ETP, but the key is a clean cat5/6 cable from the demarc(ETP) to the filter, and a clean cat5/6 from the filter to the modem. By clean I mean nothing else connected to it. What goes on the old voice side of the filter does not matter.

The Black/Yellow pair in the demarc should connect to the line(orange) of the filter, the Green of the filter to the modem and blue to the old voice wiring.

The tan/white pair on the lead in is the 2nd line which is not currently in use.

If you site the filter in the demarc then the cat5/6 line from the demarc should have the voice(blue) line on the blue pair and the DSL line(green from the filter) on the orange pair.

If the filter is sited elsewhere then connect the line in (yellow/black) to the blue pair and take that to the filter input (orange on filter).

Yes, but is there a certain way around (polarity) they must be connected - ie. black-to-white, yellow-to-orange or vice versa?

Same with the phone/modem outs, do they have a polarity?

Hi polarity is not a major concern, but the black goes to the white of the filter and so onward.

Just to clarify, polarity is not an issue, its nice to maintain it but not a biggie if its reversed as all this telco gear is polarity agnostic. But within your house wiring keep the white with white and coloured with coloured. The inbound line has black to white and yellow to coloured.

With a BT socket normally pin 2 is the coloured and pin5 the white. With RJ sockets the white is the higher number and coloured the lower, but that only applies to the centre pair all others are white is lower number, coloured higher, but dont get your knickers in a twist as the gear is polarity ignorant.
