If it was a very recnt build the property may have had an external NTE as
pictured at:

This being the case then all the internal wiring is the customers
responsibility...

No, the whole point of the NTE is to provide a clear and unambiguous
demarcation between the public network and the customer premises wiring.

According to the PDF that was mentioned earlier the NTE is always going
to be around DPC level, so I don't think you're going to need a ladder.
And if the builder doesn't fit a master socket on the other side of the
wall there's nothing to stop the owner from doing it .

Yep, thats wot it is the NTTP

Why is the 22mH choke referred to as a *shunt* inductor when it's
in-*series* with the bell-wire?

It's shunting the bell-wire as far as ADSL frequencies are concerned.

In what way? It appears to be blocking noise within the ADSL band carried by
the site's internal Bell wiring from being inserted into Line B/Pin 2 by
being placed in series with the potential noise source. I can not see that
it is shunting anything.
