In a place where all the phone wiring and outlets have been destroyed. Long story.

A thick single pair comes into the old master jack.

I need to replace all the outlets and run new cable.

Does the Telstra cable just go onto the center pins of the jack? Do I need a master jack anymore or justthe newer 2 wire jacks?

Thanks for any help.

Matt

On the old BT style jacks the telephone pair is 2&5 ie the pins second from each end. You don't need a master jack. 2 wire jacks have a 3 slot connection strip for each of the two working pins.

On US style jacks the telephony pair is the centre pair.

If all the wireing andBT jackpoints have been distroyed then dont bother with them and just install a Structured wireing system ie CAT5e/Cat6 with single runs back to a common point and install RJ45 Jacks

But If you are going to install BT Jacks then all Jacks in NZ (what ever network they are connected to ) are now two wire (and have been the standard since the introduction of xDSL in the 90s)

Re Sbiddle - thanks for letting me know you can't help.

Re UFBinstaller - thanks but cost is a big factor here

Re Bung - thanks for the useful info.

So a bunch of new BT jacks with the Telstra cable punched onto the center strip of the original main outlet with cable to the next outlet punched over the top?

Cheers
Matt

The cable from the pole to your house is usually a dual-function cable, with two twisted-pair telephone cables wrapped around a coaxial cable. That is, there are essentially three cables.

The coaxial cable carries the TV and cable modem signal. It has a centre conductor, a plastic insulator, an outer sheath made of a mesh of wire, and an outer insulator.

http://en.wikipedia.org/wiki/Coaxial_cable

This has nothing to do with any phone connection.

It should be wired into a connector provided by Vodafone. (There should be a box labelled Saturn or TelstraClear depending on the age of the installation).
If that is not the case, if that box is damaged, please contact Vodafone and get them to fix it. Otherwise you may be introducing RF noise into the network. Unless you know exactly what you are doing, nothing that you are likely do will make things better and will almost certainly make things worse, if not for you, then for other people in the area.

Out of the box come one or more coax cables for the TV and cable modems, and one or more (probably one) twisted pair phone line, which feeds your house phone wiring.

The coax is not for phone, and you don't connect it into your phone wiring.

Michael - thanks for the reply.

The cable into the old jack is twisted pair and definitely not coax. Thanks for the info.

Cheers
Matt.

If you are leaving the original 1st jack you'll have to punch over the top at that jack. Multiple wires in each slot is a reliability issue so the new jacks have a 3way strip for each leg of the pair. You punch one wire of the pair to the next jack into each strip using an empty slot.

I read Matt as starting at the telephone circuit, not going back to the Coax connection.

Thanks bung. So the slots above and below are linked to the centre slot so I don't need to punch over the top?

Yes if you use a two wire jkpt - IDed by a 2 or nothing stamped on the front - not a M or and E

All sorted. New outlets installed and working.

Lots of unused cabling removed.

Thanks to those who helped.

Matt.
