How many extensions off one filter?

Quick question, is there a limit on how many extensions I can hang off one
filter?

All my internal house wiring was done by me and plugs into the BT master
socket via an approved extension kit which is just a small adaptor that
plugs in and provides two sockets locally and a cable coming out the bottom
going to various extension sockets throughout the house.

Can I just plug one microfilter into the master socket, plug my little
adaptor into that so all the house wiring is fed from the one filter, and my
new wireless router into the ADSL output? Seems to me this should be
effectively the same as the new faceplates everyone recommends.

Cant use one of these as the BT line is hardwired into the master socket, no
detachable faceplate. (NTE2??)

Impatiently waiting for connection....

Not that I know of.

Should work fine, from my experience.

Clarification required..... 'and a cable coming out the bottom going to
various extension sockets throughout
the house.'

If it wasn't for that comment I would say probably yes, but you will require
a filter on all those 'various extension sockets throughout
the house' which may be in use. If they are not used it would be better to
completely remove them from the layout as extension wiring does have the
capacity of picking up any stray RF which will be inserted into your ADSL
signal possibly causing SNR problems

Sorry, wasnt clear, the cable comes out of the bottom of the adaptor, not
the master ssocket.
So all extensions should now be fitered, and not need individual
microfilters, I think, as the adaptor is plugged into the filter.

Hmm, all rooms have one or two sockets in them, about six total with 3
sockets used, I think. Removing unused ones would be quite a chore,
they're run under the floor.... I'll keep my fingers crossed I dont get
problems.

Surely if all the phone wiring is on the filtered side of the microfilter,
no RF can be injected back into the BT line or the router because the filter
is blocking it getting through - either BT->telephone or telephone->BT.

That's why I asked for clarification, as on first (& second) reading it
sounded as if some extensions where hard wired into the 2/1a whilst the rest
where run via the plig in adaptor.

If as the OP has clarified everything is running from a plugin adaptor then
as long as they use a good quality filter everything should be ok (poor
quality filters could allow the RF problem to rear it's ugly head)...

if you're going for a single filter make sure its a good one, the size
of the ring capacitor varies and a cheapo filter may struggle with the
ringing of a lot of phones.

I was thinking that too, changing one of the secondary sockets to a
master or pbx master would solve this too (that's what I ended up
doing, I only connected 2-5 out of the filter and then put a master in
place of the first extension socket)

You can even get the bell capacitor to convert a secondary socket to a
master one, if you want to be lazy!
Available at www.solwise.co.uk and web site /staff have much useful
info, besides filters/BT type Master sockets for those of us who don't
have.
