Apprecaite there are a few posts on this and having read the ones I could find, thought I'd ask as still wasnt sure.

Currently running wires in a stud wall for home cinema and in process have decided to move ( what I think are) phone points. There are two in total and each jack was originally on the opposite sides of the stud wall.

One box is 2 inches square, made be telepermit and was connected to a single thin white telephone wire coming down from the roofspace. There are 6 punchdown slots. The blue wire was punched into 2 and the white wire was punched into 5.

The other box is about 5 inches long x 2 inches square,is also made be telpermit but has a sticker inside saying Modempak. It has 2 thin telephone wires feeding into it from the roofspace. Again 6 punchdown slots. This time each blue wire from the x2 cables is punched into slot 3 and the white / blue and white striped is punched down into slot 6.

Why the difference in punchdown slots. Im assuming the first is purely telephone but the other has a different use?

Thanks for any tips. I am also assuming I simply recreate the connections in the same slots when I move the wallplates.

Thanks again

Google Telephone wiring and you'll find out all you need to know.
They aren't made by Telepermit. The sticker indicates they are telepermitted by Telecom NZ.
Wiring is slightly different depending on whether you have 2 wire or 3 wire circuitry in the house. 3 wire required a master and slave sockets and are long outdated. 2 wire are all the same. Just be aware some old phones won't work properly on 2 wire system. I had an early Panasonic answerphone that would only work on a 3 wire master. Wouldn't ring on a 2 wire.
Best practice these days is to fit a splitter at the junction box from the street and run cat 5 or cat 6 cable to the sockets. I use 2 wire Telecom sockets for phone and twin rj45 sockets for ADSL/Phone outlets. Much better than relying on filters (usually poor quality) at each socket. I pulled a 2 wire apart and found that 1,2,and 3 are all connected together as are 4,5,6 so doesn't really matter which ones you use.

The older square jackpoint you have is a just a 6-pin type and has a termination for each of the pins. Punch the wire in to the middle two pins and you will be good as gold.
On the newer jackpoint the terminating blocks are just all common'd up. So as long as you put one wire on one side and the other on the other side it doesn't matter which pin you punch it down on out of the three.

Because the 2nd cable on the modempak jack is simply daisychain wiring to the other jack, so the 3 punchdown slots on each side are simply an easy way to join the wires instead of using a separate joiner.

Time to find a new industry!
