RunningMan:
Stryfe: Its worth noting that the central splitter wont really change the quality of your line and if your service is naked its pretty much pointless as there should be no voice frequencies (carrier or modulation) to separate from the xDSL signal...


Not quite correct - that only covers one part of the reason for a master splitter. The other part is to isolate any existing poor house wiring and line stubs that have a dramatic impact on DSL.

It's only pointless on a naked connection, with a single outlet, with good quality cat3 or better UTP wiring, with no line taps/ stubs or other poor connections.


It's only not quite correct when taken as a standalone statement, out of context with the rest of the reply it was quoted from :)

The original reply it was quoted from didn't cover single outlet, with good quality cat3 or better UTP wiring, with no line taps/ stubs or other poor connections, which is half the reason for the splitter, hence why I thought it prudent to add.

It's a common misconception that naked connections do not need a master splitter. This is only the case in the circumstances I noted above. While the function of filtering DSL noise off the POTS circuit is obviously not needed, unless you have a good transmission line, by either the setup noted above, or by installing a master filter to isolate existing wiring, then xDSL sync will suffer.

Option 1: Since you have run the Cat5e to the router point already, you could put the router there. No need for splitter since you have naked DSL, just disconnect the daisychain to the lounge and replace it with another jack that you can use to connect the output from your modems VoIP port, so basically extending the VoIP output through to the lounge and not connected to the Telecom wiring at all. Could also have cables run through from any other room to that cupboard with a RJ45 jack on each end, to extend the ethernet outputs of the router to wherever you might want a wired computer, mysky, online TV, or other ethernet outlet.

Option 2: Run the Cat5e all the way to the outlet in lounge (or directly join to existing cable and remove the cupboard outlet) and put the router there where you can connect anything directly to the router without having to run cables back to the cupboard. Router would sit near the TV and phone, along with any other ethernet enabled gear or wired computers you might have. Since you have naked DSL you would have a direct link to the router without anything else sharing the line, so again no need for splitter. Phone plugs directly to the routers VoIP output so its not actually on the telecom wiring.

I like option 1, mostly because I'm an idealist lol.

Final results.

New solid core CAT5 from router directly connected to line, not using splitter;

.................................Upstream..........Downstream

Actual Data Rate=.....1001kbps......... 14259 kbps

Noise margin = ..........13db................. 12db

Attenuation=..............13db..................23db


& NEW ALTERNATIVE

New solid core CAT5 from router via splitter to line;

.................................Upstream..........Downstream

Actual Data Rate=.....1012kbps......... 14252 kbps

Noise margin = ..........13db................. 12db

Attenuation=..............13db..................22db

  

ORIGINAL...................Upstream..........Downstream

Actual Data Rate=.....1017kbps....... 14114 kbps

Noise margin = ..........13db............... 12db

Attenuation=..............13db................23db

 

FIRST MOD.................Upstream..........Downstream

Actual Data Rate=......1012kbps....... 13716 kbps

Noise margin = ..........13db................ 12db

Attenuation=..............13db..................22db

So overall an effective waste of time & money ;)  New cable & splitter and couple of hours resulted in a 1% ADR improvement. Oh, and I dropped another $9 on a set of security bits so I could open the telephone connection box. But at least now I can put my tools away knowing I have not taken it backwards...

So now I am moving out and want to revert the wiring to the original, so the new owner has no hassles. Would appreciate some advice with the right steps...can't find the 'before' pictures I took :(

At the junction box I'll connect back the old telephone wire to where the master splitter is connected, leaving out the master splitter.

At the main phone point I'll connect back the other end of the old telephone wire to where the data cable is currently connected.

Then how do I add in the secondary socket again? Any help appreciated.

Just leave it. It's not your problem if the new owner decides to install a pstn line into a house set up for naked DSL.

I'd prefer to stay on good terms. As I have all the tools and the old wiring is already there then an hour to reconnect it not a big deal...

Just leave it. benefit the new owner at the end of they day. Unless you have images just leave it. A Chorus tech can revert it when the new owner moves in. They would need to get a connection and wiring.

So the new owner confirmed that he would prefer regular wired sockets. If any one could help with tech advice that would be appreciated. 

Thinking it through I am assuming I connect a second pair on the main cable (between main socket and junction box) to the primary socket and connect that pair to the extension. If this is correct just need to know which points in the socket to connect to.

This thread can be closed now, job all done. Found this doc - http://www.telecom.co.nz/binarys/step_by_step_2_wire.pdf - at Telecom handy, provided just enough info to let me switch them back ok.
