Blue and brown wires all match up but not to sure where to place the orange and green wires?
New house and will only require phone lines for NBN Connection.
Thoughts?

Wire to the 568A configuration. The 568B is mainly used in America. You would generally only wire to 568B if you were an international company who had their network already wired to 568B and needed to communicate with their network. Also keep the twists in the pairs going as close to the termination as possible. Each pair is twisted at a different ratio for a reason

You have untwisted the cables too much and the punch down terminal is not designed for two cables. It will probably still work but it's not ideal

Don't do what an installer did in the Darwin Magistrates Court in the late 90's and terminate the entire build's data points with any white cable conductor and any colour conductor (ie: blue, orange, green, brown same signal. b/w, o/w, g/w, b/w same signal) . The installers excuse ? - "I come from Melbourne". True story

I prefer 568A as I always think of the orange pair as the second pair.

It really doesn't matter which standard you use, as long as you use the same standard on both ends. Doing it that way will result in the pins on one end matching the pins on the other end no matter which standard is used.

Edit: are you using a punch down tool, or a screwdriver? In the old days I think the wires used to come in from the outside (similar to what you have done), but as far as I have seen lately, the cables are generally terminated from the inside out. This is to reduce the amount of cable that you have to untwist.
Also, the proper punch-down tool cuts the end off the cable as you push down the connection.

The Krone one's used to be designed for multiple punch downs weren't they? I'm not sure if they are Krone or something else.

My boss at the time decided to use AT&T punch down blocks together with Krone RJ45 outlets. Of course, one was wired as 568A and the other was 568B, so when wiring ethernet it meant that you had to wire it in a strange way.

a quick google will give you everything you need to know . just be wary that any cabling work needs to be signed off by a licenced sparky otherwise come the time you need to make a claim for whatever reason and you have done the work. DENIED .


doesn't really matter if you use 568a or 568B . just make sure each end is the same . to do 568A follow the colours around the outside of the rj45 socket

white orange -orange-white green-blue-white blue -green-white brown- brown

Yep. 200mW @ 3.3v packs a real punch. Be careful of plugged in ethernet cables!
what part of the law says you cannot run cat 5/6 in your house unless you are a sparky?

edit: just saw its an ACMA thing. Well at least the mines I cabled up in the 90's have not burned down yet...

no **** it carries stuffall electricity but the fact it carries an electrical charge , as tiny as it is, still means cabling by law has to be installed and signed off by a licenced cabler . If it wasn't law i wouldn't have all my technicians who install cctv and run cabling in premises licenced would i ?


there is no law to say you can't run cabling yourself and most people with half a brain can do it properly, at the end of the day it's not legit .

Just to clarify, don't you need an Austel license? I.e. an electrician doesn't necessarily have the right certification to install cabling for phones and data? I know it used to the case for wiring connecting to the phone system, although I am not sure if only data within a house requires this.

You don't need a licence for anything just do it all as a handyman person on airtasker, regulatory bodies don't give a stuff about this they are too busy trying to prosecute legit businesses who can pay the fines for trivial things and at the end of the day most of the consumers who get proper protection using licensed trades would rather save a dollar using these clowns.

I did my license and all the endorsements in the mid 90s. At the time you couldn't sell your services as a cabler without being licensed, but they didn't care about home self wired data networks that didn't connect to the telecommunications network. Tothe best of my understanding no one has ever needed to be a sparkie, or needed anything checked by a sparkie, if they are acma licensed, but the sparkie myth is sure a common one.
