Are analog trunks still in use anywhere?  The phone system has been
digital for many years, long before there was an Internet. It'd have to be
an extremely old cable to require analog trunks. Anything running over fibre
would most certainly be digital.

They still have the cables and they are used.  Mostly they are used as
digital trunk lines, but not every one has been converted do to their age.
The expense of laying a new fiber cable across a large body of ocean/sea is
something that slows up the process of many parts of the world getting the
better/faster connections.  The poorer the country, or the less number of
potential users of the service, the longer it will take for the giant
communication companies to spend the type of money needed to give these
users the type of service many of us enjoy.  Europe has a better broadband
system than most of the USA does.  I saw a program for places like the
Netherlands and other European countries where they have a very large
section of their country with fiber to the home and they have many different
companies to choose from for broadband.  With that large competition for the
broadband market, their Internet prices for 50 MB/s bandwidth is lower than
my area of the USA for a 5 to 10 MB/s access.  We have just two options.
Cable modem service or a DSL service.  We pay $50+ a month for either.  On
some science TV programming, they showed services for as little as $15 a
month for the same services.  It all comes down to how good is their trunk
system and how the marketing controls over those trunk lines are regulated.
For countries like New Zealand, they have to rely on a limited trunk cable
on the ocean floor.  I would wonder if it was possible to run a trunk line
from their nation to Australia.  Would it give them more access, or is
Australia using the same trunk cable system as well.

Sorry to jump in on a whim like this however, there are quite a few
countries out there in the world now upgrading to fiber as the defacto
for residential "broadband internet" platforms. A few years back when
I was doing the Cisco CCNA course my then lecturer who was an
ex-university lecturer stated that during his frequest travels to
China, they had 100Mbps to the port on the wall at home.

In fact even in Europe they are starting to offer psuedo-metro
solutions where you get either 100Mbps or 1Gbps connections directly
to the wall for business or residences.

The question with these speeds then becomes can non-carrier and
essentially consumer based hardware support those speeds?

Even VDSL2 needs a bit of power to be able to get the maximum out of
between 32-64Mbps which is rated at.

Without going too much off-topic looking at most business based
network kit: Cisco, Juniper etc.... they can't get anywhere near
100Mbps on routed connections.

The $5000 29xx series of Cisco is claimed to do round 75Mbps
manufacturers figures, so in essence you are probably looking at round
65-70Mbps. I know for a fact that the Cisco 1800 series maxes out at
round 50-55Mbps when using inter-vlan routing, the 800 series is worse
at 40-45Mbps. (I have a few Cisco's at home to test with :-) )

At work our Juniper firewalls doing inter-vlan routing will only
manage 400Mbps in conjunction with $35,000 Cisco 4900_m switches.

Actually it's cheaper and better to build one's own routing system
however, that is waaaay off-topic. :-)

So in essence I beleive that network gear needs to get better if we
can truly utilize high-speed carriers which are fast coming directly
to our homes!
