Wiring from Master Socket to slave extension

I currently have a master socket downstairs with an Openreach BT VDSL filtered faceplate. From the MS a cable has been run (some years ago now) to an extension slave socket in another part of the house and from that socket another cable run to a further slave in yet another room (all done professionally).

What I want to do is remove the wires for that first slave socket from the MS - pins 2 & 5 and connect them to the two empty pins on the front of the VDSL faceplate. They should then be filtered, removing the need to use VDSL micro filters and I should be able to use a telephone to RJ11 cable straight from the slave into the HomeHub?

Now the question - does it matter which way round the wires from 2 & 5 are connected to the two pins on the MS faceplate? My instinct is that the polarity isn't important but would like that confirming?

I assume that once I go down this road both slaves will then become filtered and only of use for Internet i.e. no longer able to be used for phones?

Thanks for any assistance in advance.

It doesn't matter, but it's easy enough to wire them to match the extension socket.

Yes they'll be filtered and only suitable for broadband.

Make sure the existing wiring is twisted pair.
 
I worked along side BT for a couple years...

I second bremen, it doesn't matter which was around the wires are done, but its good practice to match them - That's what I did anyway


Only be used for BB, I know I am just confirming what bremen is saying but at least you have 2 peoples experience so you can cable away!
 
You've got this the wrong way around. A filtered outlet doesn't have the ADSL/VDSL frequencies on.

The IDC connection point on the removable part of the NTE5a is for filtered extensions e.g. telephones.

Edit: Wait, I re-read this and you're talking about the connection points on the bit left behind when you remove the half-height faceplate. In which case anything wired off that is unfiltered so will be fine for VDSL. If you want to connect a phone then you will need a filter.

It doesn't matter as long as it's filtered. You are simply separating the two signals. Lots of people already done this and apparently works perfectly. Can post links if you wish to see and read the procedure.
 
See my edit. The VDSL side of the faceplate is totally unfiltered. The filter sits between the voice extensions and the line to ensure that you can't hear ADSL/VDSL frequencies on the line and the DSLAM doesn't experience interference from phone calls.

If you want to move your modem then you use that pair of IDC connectors. If you want filtered extensions then you use the set of 3 on the small removable half-faceplate.

Excellent, we are all on the same page. I can now put the modem where I want it and not have it anchored to the master socket. :D
 
Update - I used the Krone tool and punched the two extension wires into the IDC connectors on the faceplate - BB signal on extension first class and no more micro filters.

I now have a dedicated connection for phone and broadband via the VDSL master socket faceplate, plus a VDSL extension in the room where I wanted the Home Hub.

What has surprised me are the two further slave sockets that run from the first slave i.e the VDSL slave extension. I had initially thought they would no longer work. Indeed when I tried connecting an old landline phone to the other slaves, whilst the phone immediately picked up a dialing tone it knocked the BB signal out to the first slave - red light on router.

However, if I put a micro filter on those sockets then connect the phone again the socket works fine and it doesn't knock the BB signal out or diminish the speed. It appears to be a win win.

The connections you used carry the full signal. They basically bypass the filtering in the VDSL master socket.

Hence I suppose why I no longer need a micro filter on the slave socket and why I have signal to the other two slaves but if I wish to use a phone on them I would need to fit micro filters, though not if I use them for BB?

Would I be right in thinking then the RJ11 on the MS is the full unfiltered signal too?
 
Yes the RJ11 is unfiltered.

You only ever need a micro filter where a phone is connected.

I believe that will the self install things have moved back to ISPs supplying external plug in filters.
 
I'm not sure how your extensions were wired before where the VDSL worked on them but needed a filter. Or was this done to move the router?

If you want to move the router and also do away with filters then assuming a 2 or 3 pair cable is being used for your extensions you could have one pair being filtered and suitable for phones, and another pair carrying the VDSL signal. Then you just need to gel crimp the VDSL pairs together as they pass through the extension sockets until you're at the socket where you want the modem, at which point you can swap it out for a double socket and terminate the VDSL pairs on their own outlet.

The extensions worked previously because this was the new frontier i.e. BT customer self-install using micro filters. Although the speeds were fine, in fact excellent, I wasn't happy to keep using micro filters, so I picked up the Openreach VDSL face plate and embarked on this way of doing it (after reading a number of posts where others have done the same).

I had thought of following your suggestion - however, for reasons I cannot begin to explain, the chap who fitted the extensions (ex BT man) decided I would never need the extra twisted pairs so has lopped them off right up to the outer sheaf. My face must have been a picture when I unscrewed the master socket :eek: So you see, short of running a new cable from the MS to the slave around the outside of the property I only have the one twisted pair.

However, given we have a DECT phone with remote handsets, having a fixed phone in other rooms is no longer a problem.
