New BT Iplate questions.
Peter Crosland
Plusnet I was puzzled by the fact that they said it should only be fitted to
NTE5 faceplates with the BT logo, and not the ones badged Openreach. So I
decided to investigate further. What I have established is that the fixed
part, that which is screwed to the wall, of the BT and Openreach NTE5 units
are identical both physically and electrically other than the logo.
I then looked inside the removable part of the NTE5 set. These differ both
physically and electrically. The Openreach one can be distinguished without
dismantling by a small moulded cylindrical protrusion below, and to the
right of the 4 way connector for wires. This allows clearance for an
additional capacitor that isolates the bell wire.
The Iplate has an inductor and a capacitor. Both the BT and Openreach
versions of the removable faceplate physically fit the Iplate but since the
instructions say not to use it I assume that there would be some undesirable
electrical interaction with the Openreach version.
As I don't have access to the necessary test gear I can't investigate
further and with the parlous state of my ADSL connection I don't intend to
experiment with it. The two types of NTE5 were kindly made available for
examination by a friendly builder who had salvaged them from buildings that
were being renovated.
I would be interested to hear from anyone who has any relevant detailed
knowledge of the IPlate design and application.
The email address is valid if you don't wish to comment publically.

Think you'll find the the Iplate & the Openreach faceplate do exactly the
same job which is to choke any interference picked up by the bell wire
reducing your bandwidth. that's what I've gleaned from asking around but
like everybody else we're being kept in the dark.
One suggestion though do not pay to have it fitted as it would probably be a
complete waste of money (the fitting charge that is)

It seems that the two devices should do the same but why does the IPlate
need the addition of the wire wound inductor?

Agreed but it has been designed so that it is very easy to fit assuming one
has a screwdriver and the ability to use it!

True, but remember the NTE faceplate will be free whilst you have to pay for
the Iplate so it's just got to be better (tongue in check sarcastic mode
off)

You'd be amazed how many people don't want to even take their own faceplate
off, even thought it could save them (quite literally) hundreds of pounds so
I'll wouldn't be suprised if some do want to pay to have the Iplate fitted.
Can't help but wonder about all those who have got the latest NTE who then
go on to buy/have fitted an Iplate as they are supposed to be mutually
exclusive. I can see more fun & games in the future

That is a question I would like answered too. I have a new house with
integral garage and the BT Master socket is in the garage. I connect
my router into the socket in the bedroom above and it is the first
socket from the BT master socket. Would there be any benefit from an
Iplate in this situation?

I don't profess to be an expert on the iplate but as I understand it, it
adds a high pass filter to the 'ring wire' so that ADSL data only goes
down the proper twisted pair to extensions (unless there has also been a
NTE filter plate at the master socket) and no 'one-legged' version of
the data escapes down the ring wire - causing an unbalance in the data
being sent around the house to extension sockets.
The whole advantage of fitting the NTE filter plate is that the ADSL
data is taken off the line at the earliest opportunity and not sent
around the house to multiple sockets. Each one of these can provide a
'mis-termination' to the data which can cause interference and
distortion to the ADSL signals or act as a pick-up of unwanted
interfering signals from electrical appliances etc.
(think like a ripple in a pond where anything sticking up out of the
water causes reflections which can cancel out the waves completely -
just the same in electrical signals in wires)
I am sure there will gradually appear people's experiences with the iplate.
In your situation, I should (temporarily?) connect your router (via a
filter) to the test socket behind the lower plate of the NTE.
If that makes a significant improvement in performance, consider fitting
a NTE filter and running a separate RJ11 up to your bedroom.

I agree with this approach with one proviso - don't use a normal "flat"
RJ11 extension cable.
The OP should look at fitting a master socket faceplate filter of the
type that has a through connection from the back of the faceplate,
allowing the unfiltered ADSL signal to be connected pernamently e.g.
ADLnation XTE2005. Then connect the current twisted-pair phone cable to
the bedroom computer to the straight through connection and all the rest
of the home wiring to the filtered connection. This will remove the
ADSL signal from all the house wiring at the master socket, except on
the cable to the computer. This cable should only connect the A and B
wires to a single, twisted pair, with *no* other wires connected. The
socket in the bedroom should then be replaced with an RJ11 type so it
won't accept a dumb telephone, or with a filtered socket (e.g. XTF85),
if a local phone/fax modem is needed.
I find this to be much better than trying to run a plain RJ11 or a phone
extension cable, especially where this isn't twisted pair, all the way
back to the master socket's RJ11 ADSL socket. If you do want to use an
extension cable, you can get twisted pair RJ11s which do work - I've
even improved installations replacing only the cheap, flat RJ11 cable
supplied with the modem/router. It's (not) suprising the noise picked up
by this standard "ADSL modem" cable between the wall socket and the
modem/router, especaily when it is simply dropped down the back of the
computer with all the other noisy cables...

Interesting John
Hadn't come across this product. As you say it makes extension of the
ADSL part on a separate twisted pair cable (mayb even CAT V with it's
heavier construction than regular phone cable) easy.
Clever having the AB leg at the rear - I guess this is a filtered A/B
leg rather than a direct connection to the BT A/B line.
Pity they can't spell in the website though:-

No, it *IS* a direct connection to the A/B.
Phones/dial-up modems/faxes/skyboxes are be connected through the
filter, adsl modems/routers need to connect to the non-filtered line.

The "ADSL filter" does *nothing* on the ADSL side, other than providing
the RJ11 socket. The "ADSL filter", getting the ADSL signal separated
from the telephone signals, is actually part of the ADSL modem's design.
The ADSL filter really a "phone filter", in that it is a low-pass filter
that sits on the phone side to prevent the ADSL part of the signal (up
to more than 1MHz) being sent to the unmatched telephone-type devices.
It also has the function of preventing high frequency noise picked up or
generated by the telephony devices interfering with the low-level ADSL
signal. For more information see the circut diagram at the bottom of:
http://www.adslnation.com/support/filters.php. From this page, you'll
see that not all ADSL filters are alike. Personally. I've probably
thrown away more "plug-in" filters that I've done fixes, especially
those provided "free"...
The fact that the filter does nothing on the ADSL side is the reason for
installing one good filter as close to the incoming line as possible.
Practically, this means using one of the master-socket faceplate
replacement types. With this, you prevent the ADSL signal being sent
all over your house wiring, where it has to contend with all sorts of
high frequency interference sources, not to mention having to run
alongside an unbalanced "ring" wire acting like an aerial.
There's a good blog on ADSL wiring at: <http://yarwell.blogspot.com/2005
_08_01_yarwell_archive.html> and a page at:

Thanks for the link, Bob.
I ordered one yesterday and it arrived in the post today.
Fitted it a few minutes ago and - bingo! Speed has gone from its usual 1 Meg
to 1.9 Meg immediately!.
Well worth the money.

No probs. It's actually one of my ex work colleagues who's selling them
via that website so it's a bit of a shameless plug if I'm honest ;)

I fitted mine this morning. Instant increase in sync rate from about
2500kbps to 5000kbps. Just waiting on BT Wholesale's DLM kit to increase
my throughput now.
> Well worth the money.
Agreed, I'm well happy with the above results! :)

As a result of this thread, I ordered one too, got it today. My sync
speed has jumped from 1856Kbps to 2272. If my memory of the thresholds
is right, if the router can hold the connection that'll give me a 2MB
link up from 1.5. Not bad for 15 quid. :)
(I already run my line with a lower-than-usual SNR ratio, I've seen it
hold a connection at just 2dB and VoIP works fine there. Mind you, the
previous firmware on my DG834GT used to fall over at around 4dB. I'm
running 1.02.09-UberGT)

How does that work if you already have an ADSLNation filtered
faceplate .?

You can get a replacement faceplate for the NTE5 here which does the

There is no need for it with the filtered faceplates we sell-these are
made by the same people who have made the initial batch of iPlates.
