Roger, thank you for your ideas.

As far as I know, the ADSL signal hasn't changed - BT couldn't
tell me whether they had upgraded the exchange, and my ISP
confirmed to me that I was still on the 1 meg broadband. Further,
no new equipment had been brought into the house around the time
of the broadband dropping out - so I am still at a loss as to what
has caused this. It worked fine for months, and now has dropped
out and won't come back. I really need to have broadband access at
both telephone points.
Currently the extension to the secondary socket is taken around the
outside of the house, over quite a long distance (>30m). I take it
from what you are saying, that this needs to be replaced with a
'digital' cable, rather than the BT cable currently used? Sorry to
appear thick, but what is the difference?

I think I said digital *extension* rather than cable. The cable is
no different - providing you are using good quality twisted pair
phone cable. [Note that it's not intended for external use,
though!] What is different is where it's connected. A digital
extension is connected directly to the incoming line, on the
exchange side of the filter. The ordinary analog extensions (when
using a filtered faceplate) are connected *after* the filter -
which is why the Clarity faceplate is good, because it provides
connection points *both* sides of the filter.

Can I use the existing BT secondary socket with this digital cable,
and use micro filters for each device, as before? The existing
wiring for the secondary already comes into the back of the
socket, and I assume it would be relatively straight forward to
replace it with the 'digital' cable, assuming it works on the same
basis?
You won't need a filter in the remote socket if you use a filtered
faceplate. The remote socket can be digital (unfiltered) or analog
(filtered) depending on which side of the filter the wires are
connected in the master - but not both at the same time. But since
your extension wiring is suspect, I'd start again with new wiring -
and put an RJ11 socket on the end, so that your modem/router will
plug straight in. If you need a phone at the remote location, keep
the existing socket and wiring for that. It should be ok once it's
filtered at source.

Only problem is that to do the job properly you would have to use 2
cables or else you could get (notice I said could) get 'cross talk'
causing errors on the DSL & possible noise on the analogue. Of course
the better the quality of cable is the less of a chance of it
happening..
