Telephone on Cat 6 cable

[binky]

I am currently re-wiring my neighbours house, who wants data and telephone in all rooms. To save time/ money I was wondering if it is possible to connect telephone to the Cat 6 cable, and what equipment would be necessary to achieve this. The house will be connected to BT standard telephone entry point.

Couple of other points:-

1/ would I still have to run individual cables to individual outlets, or can cat 6 be connected in series?

2/ Is there a combined telephone / data outlet, or plug in adaptor to work both from a single RJ45 outlet?

3/ what sort of kit would I need at the BT incoming point?

Any help greatly appreciated.

PS have been looking at the schneider delta 8 system, but don't like the price as it seems to be coming in at around the

There are specific BT master and slave units (think krone make some) but what you could do is get a bt extension cord and chop it up and stick rj's on each new end such that when its connected to the structured cabling its a straight though.

Done a bit more research, apparently it can be done but slows down the broadband speed from gigabit to megabit, which means it is probaly easier/ better to pull traditional telephone cable and keep cat 6 for data.

What? Got any links that say that cos my BS detector just went into meltdown like that crabtree switch in the black museum.

I would run the cat6 as normal for both voice and data back to a patch panel.

That way any outlet can be used for any function.

Run a normal phone cable from the BT master socket to a suitable junction box next to the patch panel. Then using RJ11 to RJ11 cables cut in half take as many extensions from the junction box as you need and patch the RJ11's into the RJ45 sockets in the patch panel.

At the other end use RJ11 cables from the wall outlet to the phones.

Sounds good, thanks

Don;t put RJ11 plugs into RJ45 ports as the RJ11 plugs bend pins 1&8 so you might as well just not bother and wire the BT sockets with BT cable and save the hassle of arsing about with adapters and cat6.

Buy a crimping tool and some RJ45 plugs and make some patch leads or use RJ45 patch leads cut in half.

Usual practice is to use the blue pair for telecoms (pins 4+5, the centre ones) as this should avoid cross connection on 10\100 networks. Doesn;t make that much difference with gigabit as it uses all cables so it'll be connected to something if it is cross connected. Whichever pins you use make sure you connect terminals 2&5 from the BT socket to the same pair in the data cable.

Just buy a kit like this JD

They have all different options but 4 phones is usually the max without using more expensive kit.

The REN standard uses whole numbers only. In the olden days telephones would draw current from the line to operate the ringer. These days however most phones draw no line current and the REN will be more like 0.1 than 1, but due to the fact the lowest REN technically possible is 1 that is what is put on the sticker.
