Hi there,

I have recently bought a house where it has the old POTS sockets on the wall. However they used CAT5 cables and just wired it for phone which is really nice.

What I would like to do is change the sockets from POTs and punch it for RJ45 sockets as we are on VOIP.

The problem I have is that where all the cables gather and is punched into the telephone module they is no label. So I have no idea which cable goes to which port in the house.

Is there a tool which I can plug into one side test which cable it is the other side?

When the chorus guy came to my house to install the VDSL he had a tool where he plugged into where the cables were coming into the house and then another tool where he just placed near the cables and it beeped. The name of that tool would be great.

Thanks

It's called a "warbler"

but you can do it with a 9v battery + clip at one end and a multimeter at the other

Or just disconnect one cable and see which socekt goes dead

If they are terminated or you plan to terminate them then just head to jaycar and get a network tester. I have this one, which also includes a multimeter. The small end has a battery and the lights flash in sequence to show you that you have terminated correctly (will in the same order) on both ends (stand at whichever end you want.

Cable tracer or tone tracer.

Warbler unfortunately gives you a lot of Google results for a native NZ bird.

Cheers.

I bought one of these http://www.trademe.co.nz/computers/networking-modems/other/auction-1001840176.htm

$6 is a bit cheaper than Jaycar! For your usage it should do but a battery will do the job even cheaper as Uber says!

If you're not in a rush you can pickup a tone generator pretty cheap on Aliexpress

Use a multimeter, short an unused pair and check for continuity at the other end/s. when you find it separate the pair and check again.

A cable tracing tool is great (I own two) but you don't need it
