How can i use phone ports in my home to expand my network?

Recommended Posts

So i have a whole bunch of phone ports in my house.

At present they are largely unused but I've tested them and confirmed they have dial tone.

Is it possible to utilize these ports to connect devices through them to my existing home network.

The ports (pictured below) are in pretty much every room in the house.

I don't think you can - never heard of using installed phone line for local networking in similar fashion to how it can be done through power points.


Plus generally if you're using the phone line for ADSL, the line filters you need to put on any other device aside from the modem restrict practically any frequency that would be useful for medium to high speed comms.

Well if it is Cat3 cabling (2 twisted pairs) then it can be used for Ethernet but only for very slow 10Base-T (IE 10Mbit) and that is assuming it is Cat3 and not crappy untwisted pairs which sometimes gets used.


The sockets have to be disconnected from the telecommunications network for this to work.

To disconnect the existing sockets from the telephone connection you are legally required to use an approved technician.


However hundreds if not thousands of people fiddle with this stuff all the time with no problems, just that if you somehow managed to bork something out there in Telstra land you are up for some fairly serious $$$ if they decide it was your fault.


Fitting and terminating structured cabling also has to be done by a suitably accredited cabling installer, but again a lot of people do their own with no problems.

Australia is far too nanny state about this crap. New Zealand seems to manage much more relaxed regulations without the whole telecommunications network being bought to a grinding halt, or hundreds of people frying themselves by doing their own mains house wiring.


So how to do it?

Personally I would not bother but would either get proper structured cabling (Ethernet) run either through the roof space or under the house (depending on construction).


If that is not an option (say renting) then use Ethernet over Power (EoP) devices like http://www.tp-link.com.au/products/details/cat-18_TL-PA4010PKIT.html for a straight Ethernet in to Ethernet out.



if you want wifi at the remote end.

You can have multiple adaptors on the one EoP network see


However there are a few things to be aware of with EoP.

Speed can vary depending on how good your house wiring is and how noisy the electrical environment is. They can be a bit problematic on different fused circuits depending on the type of circuit breaker.

EoP is a shared medium like wireless so lots of devices doing lots of thing simultaneously can bog the EoP network down.

They sometimes don't like being plugged in to power boards with surge protection. That's why the AC passthrough ones are good. Eop in to power point and then power board in to the piggyback socket on the adaptor.


Having said that they are definitely a usable and effective way of easily creating a wired network.


TP-Link have some good FAQs at http://www.tp-link.com.au/faq-406.html about EoP.


Price wise

Great thanks for the help guys.

I'll probably sack the idea of using those ports in favor of EOP.

EOP was something i had looked at but in conversations i had with Iinet they advised only 2 EOP adapter could be used to effectively create a bridge.

Perhaps that was the case with their products but it looks like the TP link above can support 6 - 8 EOP adapters so i might resume examining that front.

Again thanks very much for the help.

From memory the original powerline (EoP) adaptors available only allowed for one pair yes, but that has long since changed.

With TP-Link it is now anywhere between 6 and 264 nodes (EoP adaptors) depending on model.

Just do note they are not a magic fix and are slower than a proper Ethernet network but in some situations they are a perfect solution.

I guess eop would work well for people who rent places.

Yep this seems to be a very common usage.

What about pulling the cabling out of the walls and then running your own CAT5/6 Ethernet in the pipes. That's what i did in our apartment. Ripped out all the old landline crap and put in my own ethernet. Pipes were small though. Only enough room for the cable. Had to mount the plugs on the other end.
