ADSL
Adaptor for BT NTE5
(ADSL-hardwiring modified version : 6-way IDC block)
Back in
mid 2002, the BT engineers' NTE5 ADSL adaptor was first made available
to the public on this very website. Then we helped people out as best
we could and customised some specially to provide hardwiring points
for ADSL extensions from late 2002, and through 3 versions. But despite
ongoing pestering from us for a production unit, it's taken until
2004 for BT's manufacturer to provide us with a factory made, BT-approved,
redesigned unit for us in healthy quantities. Here it is at long last... |
| |
|  OVERVIEW
The original design
of the BT-issued ADSL adaptor isn't equipped with an extra set of
ADSL access hardwiring points, most likely because of the potential
confusion that could result from silly people not comprehending
that two of the wires coming from the box were ADSL-only, and to
prevent all sorts of strife then developing.
So the final BT solution across the board for providing subscribers
with ADSL access at locations other than at the master socket was
simply, and only, to plug a BT ADSL Extension into the ADSL outlet
on the front of the ADSL adaptor front plate and be done with it.
But it doesn't help those of us who DO have the marbles to contrive
neat hardwiring solutions in our homes and offices... 
Now and again somebody wants to use the jolly
clever BT ADSL NTE5 adaptor to filter all their voice wires in one
go, which is great. But they'd ALSO like to hardwire an ADSL-dedicated
extension cable rather than just plug one into the front of the
adaptor face plate.
WHY?
Could be for security, so the ADSL feed can't be unplugged or damaged
by children, animals or idiots, or for distribution to multiple
ADSL extension locations, or simply for a professional, neat, "hidden
wiring" style job.
It's also very useful if for anyone who wants to run both the filtered
AND unfiltered instance of your phone line in a single CAT5e cable,
side by side.
SO...
Until we took it upon ourselves to come up with and carry
out a special modification to the BT design, this was just not an
available option. (Is that applause? Ah, thank you.) So here we
are now able to offer a professionally redesigned (and even BT-approved)
version of BT's ADSL master adaptor that provides hardwiring points
for BOTH filtered and unfiltered signals for the professional installers
and power-users among you...
THE MODIFIED VERSION - DETAILS
The modified version of the ADSL faceplate now has a 6-way IDC terminal
on the rear block, instead of BT's original 3-way block, which only
provided for filtered telephony extensions.
See
the picture there?
The new terminals "A" and
"B" are direct, unfiltered, exchange line terminals, i.e.
complete with your nice clean ADSL signal. Hardwire dedicated ADSL
extension wire pairs to those. (Note: In our previous version, these
were marked "2A" and "5A" respectively.)
Terminal 4 is a dummy and remains as unused as usual in UK POTS
wiring (only there for bureaucratic reasons in this case) so you
connect no wires to that one.
Needless to say, but being said anyway because there's always somebody
who'll ask - 2, 3 and 5 are the FILTERED terminals, for connection
of extension wires for telephone-based equipment, and are exactly
as per the original 2, 3 and 5 on the original BT design ADSL adaptor.
You now have hardwire access for both filtered and unfiltered signal,
just as you have socket access for both on the front of the unit.
So in summary;
- You have
three terminals to which you can connect the wiring for any of
your extensions you want to be FILTERED, for
use with voice-based telephony equipment, NOT for ADSL.
- You have
two new UNFILTERED terminals to which you can
connect the wiring for your ADSL extension(s). See our ADSL extension
kits for this.
TERMINAL NUMBERS, REPEATED FOR ABSOLUTE CLARITY
- 2,
3 and 5 : Telephone extensions ONLY, ADSL signal now
removed (FILTERED)
- A
and B :
ADSL extensions. (Same as 2 and 5 but UNFILTERED.)
- 4
: Not used

LAST
WORD
Other than the new connector block, the essential function of the
adaptor remains exactly as per the standard BT-issued unit. None of
the internal components are changed, and filtering performance remains
as clean as ever.
Be very clear though: This
product works exactly as it says on the tin, so to speak and it's
not difficult to use - so long as you're at least familiar with basic
UK telephone wiring. What you do with your actual cabling arrangements
is up to you, and we sell this on the understanding that a suitably
competent person will plan and carry out the wiring. If you don't
understand this subject at all, then either read up on it first (there's
tutorials on this site that should help and the Internet provides
a wealth of info too), pay a trained professional installer or just
use the dangly microfilter solution instead.
(We sell good ones too if you need them instead  ) |

 Right,
now that you know exactly what you're doing, let's see the colour
of your money.
Click the orders button here to take
you to the ordering page for these gadgets, whereupon I should hope
you'll order one, and probably an extension kit too, cos I bet like
the rest of us your BT Master socket's at the opposite end of the
house from the computer! .
Come on, spend the frogskins, you know you want to. |
