Centralised Filter Installations (the Faceplate Splitter)
This page is intended to help you fit a centralised filter which is built into
an NTE5 faceplate.
The BT Master Socket
The NTE5 faceplate splitter is suitable for telephone lines that have
an NTE5 master socket. This is a white plastic square
with a removable faceplate on the lower half. The master socket
marks the boundary between the telephone wiring provided by BT
(which you should not modify) and your own internal wiring. If
you remove the NTE5 faceplate, then you will find a telephone
socket behind that is connected directly to the incoming BT line
- the action of removing the faceplate disconnects all your internal
wiring. This is a good way to find out if any problems you have
with your telephone (or ADSL) service are being caused by your
internal wiring.
The NTE5 Faceplate
Because all your telephone extensions can be wired from the rear of the
NTE5 faceplate, this makes it the ideal location to place a centralised filter.
The job of the filter is to make sure that all devices sharing the line with
your ADSL service are prevented from interfering with your broadband connection,
and vice versa.
To fit the faceplate splitter you need to:
- Unscrew & remove your existing NTE5 faceplate
- Remove any extension wiring from the back of the faceplate
- Connect the extension wiring to the back of the new faceplate splitter
- Plug in the new faceplate splitter and screw it to the NTE5 backplate
Please note that we include a free plastic insertion tool with every Pressac centralised
filter purchased from us to ease connecting your extension wiring
to the back of the faceplate.
With the ADSL faceplate fitted it is only possible to connect
your ADSL modem to the master socket (so if you wanted to connect
a PC in a different room you needed to fit an ADSL extension cable).
The faceplate has two outlets on the front - a filtered one for a telephone, and
an unfiltered one for your ADSL equipment (you plug your RJ11 lead in here).
This kind of installation does have advantages over microfilters for some users - for example it looks neater
than using individual microfilters, and it helps prevent noise on your internal
wiring interfering with your ADSL connection.
