I'm installing adsl at a friend's new place. The previous owners seem to have
made a bit of a meal of the phone wiring. I haven't yet seen where the wire
from the street enters the house (it's in the roof somewhere), but coming out
of the ceiling there is what I've seen called "Bell Wire" by DSE. It a
relatively thick solid core figure 8 wire. No twisting, colour coding or other
markings.

How can I tell which is the tip and which is the ring? There's plenty on the
net on colour coding (which is mostly american but seems semi applicable), but
little on what to do when there are no colours.

Suggests that the ring will be -48v and the tip will be 0v with a comment that
it's a balanced line so the tip is not "ground". Is this correct? A simple
multimeter test is all I need? It also mentions that the ring is blue and the
tip is white on the first pair.

Here (on page 12) Telecom suggest that the blue wire should go to terminal 5
and the white to terminal 2 on the jackpoint.

So terminal 5 should be the negative side of the pair, and terminal 2 should
be the positive?
