I havnt seen another type of face plate with 2 idc outputs on the back so far.

Have a look at these, 3 more models all with "dual" outlets (Solwise, Pressac, Austin-Taylor):
http://www.solwise.co.uk/adsl_splitters-faceplates.htm

Pressac are the major supplier to OR and also supply to Clarity, etc, (but without the OR logo).

I am looking at the 2011 version of the Pressac Product Directory. On page six is --

Centralised ADSL Filter

The Pressac Centralised ADSL Filter is designed 
to plug into a standard NTE5 residential telephone
outlet. It provides a straight through connection
for DSL modem connection via a shuttered RJ45
socket as well as a filtered telephone socket and
filtered 3 way IDC connector for onward connection
of extension telephones. With the centralised filter
system, the filter becomes an integral part of the wall
socket providing a tidy looking fixture with the added
benefit of negating the need for subsequent extension
sockets to have microfilters plugged into them. A 6
way IDC version is also available that allows onward
connection of both telephone (filtered) and DSL
modem (unfiltered) wiring.

Description Part No. Dim (mm)
ADSL Centralised Filter 3 way IDC 60.10705.PS9XX 85 x 70 x 44
ADSL Centralised Filter 6 way IDC 60.10908.PS9XX 85 x 70 x 44

The 6 way version is what I purchased from Clarity and I believe the 3 way version is known by OR as an NTE2005. Both types can be recognised by the ADSL V1.0 marking at the front lower right.

On page seven is --

NTE5 VDSL Interstitial Filter

The Pressac VDSL Interstitial faceplate is designed to be
inserted between the main housing of a residential NTE5
telephone socket and the removable Customer Connection
Unit. It is designed to allow end user installation of a VDSL filter
solution without the need for removing any existing telephone
extension wiring.
• Hi specification low pass filter with rejection
characterised to 10 MHZ
• Connection of VDSL modem via shuttered RJ45
socket
• Onward filtered telephone connections provided
by existing CCU
• Hardwired modem connection possible by 2 way
IDC provision

Description Part No. Dim (mm)
NTE5 Interstitial VDSL Filter K60.11177 85 x 85 x 34

That is the item fitted by OR at the EU premise as part of a current-day FTTC installation. The initial batch did not have the "2 way IDC provision" and they are, I suspect, what Ezzer recalls. However with the present version, when the EU's lower front plate is removed, a filtered POTS pair can be run from the back of the lower front plate (as usual) and an unfiltered DSL pair can be run from the two exposed IDCs on the VDSL interstitial faceplate.

They've been around for quite a while like that, several years I'd say in the case of ADSLnation.
(is the model name a clue? XTE-2005  )

The ADSLnation devices are not electrically identical to the Pressac devices (built to BT / OR specifications). The former contain active components, whilst the latter are purely passive.

[HPsauce]

Yes indeed, I know that, it was part of their "marketing" for a while as the "active" filtering was supposedly better.

Never found any difference between the types myself in practice though.

PS Thanks for the info re Pressac  , shows how easy it is to be confused by all this.

You are welcome. In the short time that I have made these fora one of my daily stopping-off points, I have learnt a lot from the regular members -- you included, HP. When I know that I am in possession of facts which can be added to an ongoing discussion, I will do so. That way the collective knowledge base of Kitz' site is enhanced. (And long may it continue.)

we must be kind to all wrinklies

I've had a bus pass for a while now! 

Anyway, we do seem to be digressing somewhat from the original question.....
It would be nice to hear from the originator what progress they've made on decisions or implementation.
(or answer more questions)

[jamesc123]

ok thanks guys....

I read somewhere using a single Cat5e cable to run both a telephone line and ADSL line isn't good. That when the telephone rings the voltage goes up and could send something down the ADSL line and burnout the devices at the end of the ADSL line.

Does this happen in practise? Any one else used this sort of wiring

[waltergmw]

Hi James,

I suggest burn-out is unlikely but crosstalk might reduce your modem's performance. If you are very concerned you might try Cat6 cable as that has more physical separation of the twisted pairs.

Kind regards,
Walter

[HPsauce]

It all sounds a bit implausible really and frankly too much work as you'll need to separate the pairs and put your own plugs on the end.
And NEITHER Cat5e or Cat6 use shielded pairs as far as I know, they're just twisted somewhat differently.

Remember phone and ADSL signals travel down the same wire anyway and normally don't interfere with each other at all, so it's just anything you introduce that is likely to be a problem.

Personally I'd extend phone and broadband with their own separate cables and wouldn't use Cat anything as it has far too many pairs and is bulky (especially Cat6).
I'd use normal phone cable for the phone (and NOT connect the bell wire) and shielded cable for broadband, though realistically normal CW1308 (twisted pair) phone cable is probably good enough for that too.

(but then I also use CW1308 for my LAN cabling at home - it's fine for 100mbps!)

[jamesc123]

Ok. I am thinking that 2 seperate wires, 1 for phone and 1 for ADSL to the router, would be better.

But I am also thinking it might simply be better to put the router near to the master socket and plug the RJ11 straight into the front of the faceplate instead. Although it is far more convenient having the router upstairs where it is now.

So for the 2 wires I should use CW.... standard phone cable? Both with 2 pairs? Such as this: http://www.adslnation.com/phpapps/catalog/product_info.php?cPath=21&products_id=96

[HPsauce]

But I am also thinking it might simply be better to put the router near to the master socket and plug the RJ11 straight into the front of the faceplate instead.

That's always better, after all you can then run Cat5e (Cat6 is total overkill) to your PC or a network hub wherever you want.

ADSLnation used to sell shielded ADSL cable but don't seem to any more.

You mean like this? http://www.clarity.it/xcart/home.php?cat=253

[razpag]

HP is 100% right. The phone and broadband frequencies travel large distances together from the exchange to the EU's premises, on a lot less 'twisted pairs' than any CAT cabling. Some of your thoughts seem to be over-engineering James, with little or no gain to be made. Just an observation, not meant in a condescending manner or anything. 

Go with your last idea of siting the router next to the Master Socket for best results and no cost.

Well a little less "overstated" maybe, just plain white and in various lengths. But the same basic spec under the bling.

Pressac have launched a new retail website that sells their centralised filters online - http://www.slowinternet.co.uk. 

They sell a standard ADSL filter and a premium filter, which offers enhanced noise reduction, is easy fit (no rewiring of the telephone lines) and VDSL enabled (as well as filtering ADSL and ADSL2).  A bit more pricey than the passive ADSL filtering alternatives, but I believe this is the only place you can buy the premium filter unless you are BT or OR!   The premium filter slots into the NTE5 (remove standard faceplate, insert the filter and reattach the faceplate).  Product details can be found at http://www.slowinternet.co.uk/products/premium-centralised-filter
