Hi Everyone,

This is a cross post because I wasn't sure which one to put it in and some
people may not use all the NewsGroups that I have posted it to, so beg
your forgiveness.

The main BT socket is in the bedroom and from this I have daisy chained
all the rest of the sockets in the house using the faceplate connection on
the front of the BT socket.

From some of the sockets I have filters plugged in for the phones, 4 in
total. I also have a filter plugged in for the PC to use the Broadband.

I noticed that the connection speed was getting slower and slower so I
used the Voyager 105 modem given to me by my ISP in order to findout the
exact speed. It was 320 kbps.

I disconnected all the phones in the house, tried the speed again and it
was the same. Plugged modem into main socket and speed increased to
something like 580 kbps. I thern took faceplate off and plugged modem
directly into socket, now 1.8Mbps. I plugged extensions into filter and
all phones work ok without individual filters.

Now my question is this. Do I have a fault on my original installation of
the sockets in the house, or, should I have just used 1 filter in the main
box as I have at present ?

Your comments are most welcome.

It is possible that you havea fault on the extension sockets installed
throughout the house. It may simply be that these sockets have been wired
without the benefit of the correct twisted pair cable. It is also possible
that the "ring" wire is connected, but its partner in the twisted pair is
not, thereby unbalancing the pair and introducing noise.

What you should do is formalise the test arrangement by installing a
faceplate filter. An example is the "NTE5 compatible ADSL filtered
faceplate" see: http://www.solwise.co.uk/adsl_splitters.htm
All the extension cables should then be wired to the filtered output of the
faceplate.

If it isn't possible to install your router or modem adjacent to the
filtered faceplate in the bedroom, then use Cat5 cable to run the unfiltered
signal to a RJ45 socket at a more convenient location.
