1442904	2017-12-01 04:26:00	It's me again! My problems in the earlier post regarding Ethernet cables has ben solved but now I am having trouble with the telephones. We have 3 phones, 2 portables, and one fixed one. Since We have had fibre installed, the phone that is plugged into the modem is fine, but the other two are dead. Before fibre there was an underground line that when to a master? jack point (the one with a capacitor & a resistor?) in the main bedroom, and then on to a junction box in the loft. Cables then run from there to another phone in the living room, and to a phone in the hall. There was also a link to an outlet for the computer ASDL line. I have removed the computer line, and the master jack as this had been damaged during our earthquake "repairs". It seems that screws in the top had been tightened using a power driver. I have replaced it with a standard jack. Now I have the hall phone is plugged into the adjacent modem, and another line runs from the modem to the loft junction box. The other two phones wired in parallel from the loft junction box, and neither is working. Do I need the master jack and if so where does it go? I have looked at some information on the web, but they don't seem to cover the situation with fibre. One of those was from PCWorld PressF1 forum. The information that I can find talks about two wire operation, presumably white on pin 2 and red on pin 5. Most of our cables are 6 wire (black, white, green, blue, red, orange), and one is 4 wire (yellow, green, blue, red). I also understand that the fixed phone needs a UPS if it is to continue to function during a power failure, if so what size and where does it fit in the layout?	Brucem (8688)

The fixed one is in the main bedroom, and the others in the hall, and the living room/kitchen. Before fibre arrived an underground line came to a junction box in the subfloor area. From there a line ran to a master jack in the bedroom. A line ran from there to a junction box in the loft, where two lines ran in parallel to the hall phone and the living room/ kitchen. There was also another parallel line from the junction box to an outlet at the computer for the ASDL connection, I have removed the is line. The fibre modem is adjacent to the hall phone which is connected directly to it, as is the answer machine via a double plug. I have connected a line from the modem to the phone jack that used to supply the hall phone. In investigating connections I found that the master jack was quite damaged, I am sure by the people undertaking the earthquake "repairs" using a power screwdriver. I have removed this and replaced it with a standard jack. I see from one of the items that I read on line that 2 wire operation is preferred, presumably white on pin 2 and red on pin 5. Our cables are 4 or 6 wire. Do I need a master jack, and if so where? I understand that to ensure operation of the fixed phone during a power outage a UPS is required, Where does this fit and what size is advised?	Brucem (8688)

Only way to tell would be to check inside the demarc, there's no telling what you'll find but telcos normally keep it sane. You may have a jack point that is ran to multiple jacks, which you may consider is a master but normally its someone like a sky installer doing the easier way. You don't need a master jack, someone with more telco knowledge would be able to explain more. pin 2 and 5? as long as they on opposite sides, quite possible polarity required too. I think you have 2 come in from the demarc and could have 4 wires go out, to go to another 2 jacks you could link but chaining may hinder the line quality? Fixed phone? IP phone for sure to keep the phone and internet going, fixed, as long as the wires coming in don't get damaged, power is supplied through it.	Kame (312)

The ONT, Router and if the phones are powered, them as well. Easy way to look at it is if you pull the plug out ( kill the power) what wont work. Size wise -- Depends on how long you want the UPS to supply power. If it were only something like a phone or ONT they use very little power, but something like a fridge (for example) would drain rather quick. The more devices you have on a UPS the quicker it will drain. You could buy something cheap, about $103 like this www.elive.co.nz may last 20-30 minutes or if you want to spend several Thousand $$$ you could get a LOT better / longer	wainuitech (129)
1442908	2017-12-01 07:53:00	Cant help with the Phone connections, BUT with a UPS it needs to be connected to ANY device that requires power. As Wainuitec said the emergency power could prove expensive. I prefer to ensure there's a mobile phone kept charged so that I can call the power company, ambulance etc. It's your judgement whether you need a generator or big backup battery but if you're dealing with an earthquake that may all fail too. It's pretty common in many areas to connect ONE phone outlet to the new fibre box. That may by default bring the other phones online, but it does depend where that first phone connection is made. The rest of the house phones may be out of it, but it usually isn't too hard to trace and remove the "isolating transformer" that kept old phone line and modem line separate. Phone is usually two wires so you need to search around that "master" jack point and see if you can see where to connect two wires from the operational phone line to the rest of the house. PS Don't blame your installers - their job is to connect ONE phone so that the householder can call out. The finding and fixing - in some homes another five or six outlets - is responsibility of the homeowner because there are limits to the time spent on a free installation!	coldot (6847)
1442909	2017-12-01 11:35:00	House wiring should by now all be using 2 wire jacks and the old master/ slave system should be long gone. On a 2 wire system the 3 pins on one side are all connected to each other and you can use any of them and the same on the other side. The phone line just connects 1 wire to each side and any other jacks connect to back to it in the same way. If you do have a master jack and slave jacks they really should be replaced. What you need to end up with is a cable from the ONT feeding the phone line into one of the jacks and all the rest connected back to it and the old line from under the house cut away. You can either daisy chain jacks from each other or run them all back to a common point, works either way.	dugimodo (138)

1442911	2017-12-01 19:29:00	We have 3 phones. Since We have had fibre installed, the phone that is plugged into the modem is fine, but the other two are dead. of course. It no longer runs of the copper. You could buy a phone that uses handsets instead, that way only 1 needs to be plugged into the ont. Or, as Chorus to rewire the jackpoints back to the ONT for you. They always install a little box in case people want this option. I didn't but he said he had to put it there anyway in case I wanted to later. They will do it for you so you don't need to worry about it yourself.	pctek (84)
1442912	2017-12-01 20:22:00	Previously, all sockets were connected together and one of them, the master, was connected to the outside world. So, all that needs doing is to disconnect the outside world lead-in and then connect any socket to the router phone socket. That way all sockets are connected to the router and can be used as before. What you are doing is connecting one phone instead of the daisy-chained socket string.	linw (53)
1442913	2017-12-01 20:32:00	Yep, as pctek says they sometimes install white box on the wall as some of my friends have as well . That's the master that is either plugged to your router or your ONT (white box) . 2 Degrees uses the router option, Spark and My Republic uses the white box . For our place, we had a unused phone jack on the wall as we no longer have Sky TV, they used that instead .	Nomad (952)
