A) to take the unfiltered AB signal downstairs (about 25m)

A tall house:-)

(all speech
telephone cables being filtered off at the entry point) - essential

B) Take a new speech telephone cable to near the router from the filter
point. - useful only

For A) is CAT5 really needed? Won't ordinary telephone cable do?

No. Yes.

For B) ordinary telephone cable will do, but if that is OK for A) & I
try to use the same (6 way) cable as for A then is there a risk of
cross-talk?

I suspect not much chance. If you use Category 5 cable it is more
twisted and the chances are, I suspect, even less.

There's something I don't understand here - why is CAT5 the standard
cable when apparently only half the cable is used (4 wires out of 8)?

All eight wires have been used in some networking implementations.

Also what are the standard pairings on CAT5 for sthe standard PC router
ethernet signals?

ISTR that the Clarity site gives all this. If it doesn't there are
search engines. Many data sockets come with colour coded identifiers
for which cable goes where. The main thing is that wiring is
straight through, with pin 1 being connected to pin 1 and so on.

Other posters have mentioned the Clarity master filter which is the one
I will be installing on this job. One is already in use in my own home

Then it probably came with a little leaflet that explains the wiring
colours in some detail.
