a high bandwidth DSL service.  The condo customers still get DSLon
copper, but because the copper pipe is so short they can crank a hell of
a lot of bps over it.  Enough to deliver HDTV, at whatever compression
rate they use to their set top boxes.  It's way more then the 5 Mb/s
up/down (S)DSL I would be quite happy with :-)

I still don't get why operators do this.

In my part of the world, a well-known service provider runs FTTC and
then runs VDSL into the home. Ummh...

In a previous country I used to work, a network had copper lines
deployed as internal last mile in every building they serviced on the
back of some MSAN's. When they upgraded their basement infrastructure to
fibre, they thought they could get away from having to run fibre to each
office/home in the building by delivering that over VDSL. For some
reason, even at 6m distances, running the HD-based IPTv service across
VDSL didn't work. I think the engineers in that network didn't even
bother wasting their time fixing that. In the end, running fibre from
the basement to each office/home did the trick - it's not like they were
starving...

In 2000, a big mobile carrier in an East African country was just about
the first network to build Metro fibre that hit lots of commercial
buildings. What did they do it with - run E1's for voice. This was their
fixed-line solution at the time. Why they didn't run Ethernet instead
(in 2000, when the rest of East Africa barely knew what Metro-E was, let
alone many parts of the world) escapes me.

If it's not fibre to the home or office gateway, where it makes no
difference to run either copper or fibre from the basement or the curb,
it's foolish.

Mark.
