Hooking up phone line to patch panels

I have wired out house to T586B, and just about finished all the faceplates. Picked up a good deal on some 24 way 19" patch panels from eBAY. (Cat5e mint condition for £3.5 each)

The room outlets will go to one patch panel (misc), and the other patch panel (voice) will be wired so that 12 ways are parallel for home line and the other 12 for business line ... as per picture on

in knowing the neat way to bring in the phone lines .. They currently terminate of course at BT master sockets ..( 2 separate sockets)

I have a cat 5e cable also run to the rear of these sockets to Node zero

Should I simply punch down cat5 at BT master socket, this cable would then terminate on one of the misc patch panel ways . then plug ADSL filter into patch panel front socket (crimp on RJ45 plug instead of BT431) then take phone line out of filter to input of one of the parallel sockets (voice patch panel) . Simple sketch on :

should I plug filter in at BT master socket and run a patch lead from filter to patch panel?

Just wondering what is neatest - assume many out there who have done this.

Not a lot to choose.

I hard wired a micro filter in behind a patch panel, and hard wired the incoming lines to that..

Do it at the NTE5's but don't use messy filter "dongles", replace the faceplates with these

can Krone the un-filtered and filtered connections to the back of the faceplate, no need to plug anything in to the sockets. .

The issue is I have 2 incoming phone lines - i.e 2 BT faceplates, I could change one of these on the 'BB' line but I only have 1 CAT 5 cable 'in place' at that location .. I would need 2 x CAT just for the BB enabled line and a further CAT 5 for the standard analogue line ?

In hind sight I could have run in more CAT 5 to the incoming lines location - but didn't.

Do neither.

Assuming the master sockets are NTE5s, replace the removable bit with a proper filter

wire filtered and unfiltered pairs from the back of it.

If the master sockets are not NTE5s then you need to work out where your installation starts. However a hard wired filter like

can be used to make a neat installation.

OK, so in that case, both phone lines through one CAT 5 cable and move the master sockets to gound zero.

1) Use one pair in the cable for one line and another pair in the cable for the other line. The other two pairs are spare. I suggest using the brown pair for the second line as this keeps nearest to wiring standards. 2) At your main location install a filter on each line that will generate the ringing for each line, such as the one at

From these wire unfiltered and filtered as appropriate.

This is in essence extending the A and B wires to your own master socket, from which you generate the ringing signal provide filtered and unfiltered lines.

The reason for installing a filter on each line is to keep the unbalanced ringing signal off the one cable that is taking both lines to your main location. There are claims that the unbalanced ringing signal can degrade ADSL performance.

In essence you would be doing what is outlined in

but with a hard wired filter rather than an NTE5, though there is no reason not to install your own NTE5s and filters should you wish to do so. Note what it says below the diagram, "This piccie should be wholly self-explanatory. To be honest, if it's not then it's probably not for you, perhaps a paid installation by BT is a better choice. I don't mean to be patronising, but that's about the size of it and there's no polite way to say it."

Hindsight is wonderful thing. Asking first is useful too.

Don't forget that most microfilters have an REN of only about 2 so one filter and lots of extensions may not work too well unless you intend to use PABX master sockets at each extension.

That seems a sensible way forward .. leave the 'incoming NTE5's in place, connect CAT5 onto the back connectors, and then put 2 more NTE5's in Node zero .. make these the ones with a filter in lower half .. then patch leads form that to CAT 5 panels ....

I asked and read all I could, the UK Home automation wiring guide was a great help.

They are NTE5's ... but the lower portion is standard type phone socket not a filter.

I think a combination of Andy's suggestion and your previous mail may be a way forward ... simply leave the masters as they are - leaving them as demarcation point... use the CAT 5 lead to extend the A&B legs for both lines to Node zero, and install 2 CAT5e's with filters at that point ... then patch outputs for phone & BB to appropriate patch panels.

Can you get secondary NTE5's with filters ? ... don't need to add another master, as the NTE5's at demarcation point will be masters.

house extensions on the other, but an REN of 2 is low ... I could always obtain an REN extender.

I am using a standard structured wiring - T586B, I will be using LAU at each RJ45 outlet to convert to BT plug .... there are PABX versions of these, would they be of any benefit? ... assumed they were only of use if you were using a PABX ?

I outlined two approaches at that point in an earlier posting.

NTE5s come as NTE5s. Filters are added to them if one wants to. The alternative is to use a hard wired filter, as I indicated before, like

... don't need to add another

Master sockets do a number of things. Not all of these things need to be done at the master socket though. That depends on how you want to wire things up. In essence that resolves into where you want to generate the ringing signal.

Personally I would use the hard wired filters I have mentioned several times at your main point. I would connect these to the master sockets using a pair for each line as I have mentioned before. I would wire filtered and unfiltered circuits from these filters as appropriate.

If you are only using one pair (2 wires) on BT connections 2 and 5 for the telephone wiring then each adapter should incorporate a ringing capacitor to restore the ringing line (pin 3). These are usually called PABX masters because they incorporate the ringing capacitor but not the surge arrestor needed for external lines. While some phones will ring with only 2&5 connected many, including modern ones, won't.

formatting link
no BT4504 BT socket to RJ45 plug PABX master is an example of the sort of thing you need.

Using these the REN of the microfilter is irrelevant.

This is what I did, except I moved the NTE too. When I needed a second line, I was thinking the BT engineer might comment or complain, but no, he even used a spare pair in my CAT5 run to ground zero to put the second NTE next to the first one. He did comment on my ground zero though, something along the lines of "never seen anything like this in a house before" when pointing at the patch panel.

BT engineering staff are generally interested in telecommunications wiring. Something unusual makes an interesting change to yet another job that is the same as the last one. If it is clearly not a bodge then they tend to turn a blind eye to it. They recognise that someone who has gone to the trouble of producing a neat and tidy installation is unlikely to have connected their cable to the mains and other things that could harm them.

What they don't like is finding that there is no master socket with the seven inch or trumpeter symbol on. That may mean a number of bodges remain to be discovered. Carefully moving a master socket with a seven inch or trumpeter symbol on it is something they tend not to object to, provided it is done properly.

They get more upset with alarm company staff, who are often real bodgers who connect things where they feel like, which then causes problem for BT staff and others in dealing with faults, extensions and DSL installations.

Thats fine..there are 4 pairs in a cat 5 cable..and you only need three..one for each line and one for ADSL.

Why?

Following up on this reply (and the other - thanks)

Assume I leave the 2 BT Master NTE5's as is .... and use the in built CAT 5e cable to krone off the back of these, and at other end create 2 new NTE5's ... (with filtered lower half)

Can you obtain NTE5's + filter in 'Secondary' type ... rather than master ? that way the BT existing masters stay as is .. and I only add secondary.

Also are there 'better types' ... Peter mentioned that some Microfilters only allow an REN of 2 ...
