And you call that "crappy copper" ?

Typically for me:

...and I'm in suburban Mt Albert/Owairaka, approximately 3.4 km from the Mt.
Albert exchange, so not that far. After speaking to one of the Downers guys one
day, he told me that the cables are well packed out around Mt. Albert shops
where the cables run, and interference from other users and lines in the duct is
pretty common (although line speed has been stable for me lately but hasn't
always been in the past).

The new plans only offer the possibility of a higher uplink speed, which would
be good and an improvement on what I have now. I am happy on 1Mbit if I really
do get 1Mbit of connectivity through to the Internet, but unfortunately of
recent times I haven't had that it seems.

I was pinning some hope on ADSL2/ADSL2+ which supposedly has better reach and
better resistance to noisy lines
(http://www.networkworld.com/news/tech/2003/0120techupdate.html), but when I
emailed Telecom about ADSL2/ADSL2+ timeframes a couple of weeks ago I was told
"I am sorry but we cannot advise of a date at this time." .

G.SHDSL would also possibly be better, one wonders why Telecom have never
advertised G.SHDSL though even for businesses, especially given they use it for
some of their One Office/PON connections at sites where they haven't laid fibre.
  I've never seen it used anywhere other than where Telecom want to use it
themselves........
