The companies producing old fashioned fixed line phone switches are all
having a hard time. People are moving to IP and cellphones. E.g. in
Denmark the number of fixed lines is falling. The old monopoly phone
company has decided not to invest in fixed line telephony any more,
because they think most of the market will be gone in 2010. They are
constantly firing engineers who used to install and fixed line phones.

Wireless technology is preferred in Scandinavian countries because the
prevalence of rock makes it almost impossible to bury cable. The snow makes
it difficult to install aerial cables.

The phone companies are making so much money on wireless because it is
"measured" while wire-line is not (in North America) that many execs think
the whole thing can be made wireless. The truth of the matter is that these
companies should be installing fiber in high-density areas where wireless
systems are running out of channels. Like Satellite technology, wireless
initially filled a niche but is too expensive for most large transfers.
(copper cables initially crossed the oceans; then satellites stole quite a
bit of this business; then fiber cables bought most of it back). I'm sure
you would agree that you would not want to phone a large company (HP, IBM,
your bank) and find out everyone was using cell phones. The business
community just won't tolerate the inherent noise and drop outs.

While it is true that circuit switching will be replaced by packet switching
some time in the future, the people who think it will be as early as 2010
just haven't thought about the details. In North America 95% of all
residential and commercial building are already wired with twisted-pair. In
high density areas over 50% are wired with coax. Most people have
twisted-pair based analog phones in their homes and do not want to do a
change over, so an analog-digital conversion widget is needed to connect to
the internal analog circuit to the internet. Sometimes the internet will be
just outside your door (xDSL from the phone company or coax from cable TV)
but in other instances it makes more sense to ride an analog line all the
way back to the telephone company, then convert to digital then connect to
the internet just to get access to cheap long distance). In other instances
the range of xDSL is extended farther from the telephone company by fiber
using a mixture of the two technologies called HFC (Hybrid fiber coax) or
HFTP (hybrid fiber twisted pair)
