In a modern installation (ie. something newer than about 25 years) you
only have one master socket.

The slightly more modern way to run extensions is to connect them to the
faceplate that goes on the BT master socket of the newer type with the
split faceplate. (aka the NTE5). That way, you remove the faceplate and
immediatly disconnect *all* internal house wiring, leaving the BT test
socket open. This is the best way to do line tests and the best way to
run your internal wiring.

You can also connect an ADSL modem directly to the test socket - no
filter required - this will give you the best possible connection, but
no provision for phones, etc.

The master socket does 3 things: It provides an over voltage
suppression, a "ring" signal to the rest of the house phones - in older
days this was used to "tinkle suppression" on phones with bells in them,
but isn't needed on modern phones. This can cause ADSL interference, so
the new "iPlate" isolates it.

The final thing it does is to provide a continuity loop back to the
exchange - this is so that the exchange doesn't get upset when you
unplug all phones and allows for remote testing and monitoring. (Which
BT do)

The best way IMO to wire up your ADSL modem is to replace the split
front plate with a plate with integrated filter and run all your house
phones off that filtered side - that way, no additional filters are
needed anywhere in the house and the modem plugs directly into the

I use these:



Thanks for that info. At the moment I am using all the sockets. They each have a phone connected via a filter. The one in the small bedroom also has my router plugged in to it. (No chance of not hearing an incoming phone call in this house!)

From what you say above it may pay me to have a new I-Plate for the master socket and then to remove all the filters from the extensions, even if I don't bother with FTTC. Is that correct?
