Hmmm well after a big of digging, I think I've discovered that normal
analogue telephone lines (PSTN) lines are full-duplex.

Have a look at this page for more information:

They are full duplex for voice calls.  As ring4it-ga mentions.  But is
that what you're looking for?  Since you're in the computer section
and your title was networking, I'm suspecting you might be interested
in something else.

Moving on...

This is true: "the standard telephone service to the
home is via a 2-wire pair (the local loop).?"

As for "Although two-, four- or six-twisted pair service may be run to the
home by the  telephone company," any number of pairs *can* be used.

Most homes use a two pair line and use only one pair. Primarily the
red and green wire on your inside service block. This can be used for
both analog and digital duplexing. SBC offers DSL and analog
networking on a single pair line. If your looking for more information
