Phone sockets to patch panel

leenowell · 2019-04-17T19:38:08+00:00

Hi All,I have run cat 6 cables to all rooms in my house all terminated in a comms cupboard. The BT master socket is in another room and again a cat 6 cable is run from it to the comms cupboard terminated with a BT socket. In the comms cupboard I have terminated all cat 6 cables in a patch panel.So, the question is how best to I connect the 3 patch panel ports which are connected to phone sockets in rooms to the BT socket. So far I have thought of the following1. Create patch cables with RJ45 one end and BT socket the other. The connect these into the BT socket via a normal phone splitter2. Create a 3 way cable by having 3 cables with RJ45 connectors one end and the other ends all soldered together. Then solder this onto a phone cable connected to BT socket3. I tried looking for a RJ45 splitter (RJ45 version of a normal phone one) but couldn't find oneNeither of which seem ideal. Anyone have any better ideas?Also, I assume I have to terminate the cable from the BT master socket in a BT socket rather than terminate it in the patch panel?Thanks in advance for your helpLee.

No, the broadband router/modem need the unfiltered connection, and everything else should be filtered.

(Contrary to popular belief the filter is mostly there to stop the audio side interfering with the data)

Amusingly the rest is unfiltered at the moment so might even get a better broadband connection at the end of this. Only thing I can think of is to find a filter with an RJ11 plug on to connect into the line patch and then the filtered connection (ideally RJ11 too) to the phone parallel ports.

Is my logic about worrying about the colours right?

Bit more research. This link

Seems to say that blue + blue/white are the ones as these end up as pins 3 and 4 in the RJ11 and these are the pins the phones use.

I found this filter

Which I could use by plugging into the main line patch and then connecting the filtered side to the phone parallel patches and the unfiltered to the modem (RJ11 modem lead into the rj45 ) not ideal (and expensive) but might work.

What you might be better off doing is to physically move the master BT socket to where the rack cabinet is. You can get the pukka BT cable and jelly connectors off eBay.

You can then buy a surface mount box and an adslnation faceplate from

This replaces the removable front plate of the BT master socket.

You can then plug your broadband modem into the broadband port and the telephone patch panel can be hard wired to the terminals behind the removable Adslnation faceplate. All phones will then work through one single filter

This is assuming you have power at the location of the patch panels.

I have all the equipment in one location so no boxes or filters all over the house and a lot tidier.

Thanks all. I was rooting around in one of my many cable boxes and stumbled across some RJ11 to BT adapters. So have wired it up using these for now. So I have

Port 1 - wired master socket and using an RJ11 to BT adapter have connected to it the normal ADSL filter. Modem connected to the unfiltered port. Then using a BT to RJ11 adapter connecting the filtered side to the phone ports I wired in parallel.

Phone and alarm are wired into separate ports and then patched across to these. All seems to work fine.

Need a neater solution for the various adapters etc but otherwise it works

Thanks all for your help
