Voice may be a critical component regulationwise, especially with CO
based battery backup. But in the rest of life IP bits are way more
important. I can get a generator to run my CPE and router, but if the
provider can't be bothered to power the first hop, then i'm pretty well
screwed. In California during PG&E's massive power outages you couldn't
get E911 even if you had power to your CPE in way too many cases. This
is was a huge fail.

Hi Nick
Have you considered using CPE DSL routers with VoIP and FXP analog out?
Decentralized. That's what everyone are doing here. Might be free depending
on where you get the CPEs.
Or simply getting VoIP handsets. Lots of cheap DECT bases with VoIP.

Investment for FTTH is 10 times or more than that for plain DSL.
We are assuming the copper plant is already there otherwise I will
respectfully disagree.
However the economic is not as simple as you might think. Lets do some
calculations.
Assume we can build the fiber plant for 1 million USD (*). This fiber
can
be depreciated over 25 years. That means we only take USD 40,000/year
of
the company profit.
The copper plant is already there but the DSLAM is missing. Assume USD
100
per port plus USD 100 per DSL CPE. This equipment can only be
depreciated
over 5 years. With 1700 ports this gives USD 68,000/year of the company
profit.
a 48 port dslam is 2200 (still awaiting cots on line cards for above
mentioned chassis) so its about 45 per port, CPE is about 50 a device
in bulk (inc 4 gb ports, wifi)
The copper exists, there is no ripping it out
Due to location RF links are used for data, so no need to give each
cabin "future proof" since unless a carrier will run fibre to us for
100's miles at their cost - it just aint happenin, the cost is
extremely prohibitive.
Not claiming these number are anything but fantasy as I know nothing
about
the layout of the project. Just illustrating that sometimes more money
now
does not necessary means less profit for a company.
(*) yes 1700 installs could be done for that in optimum circumstances.
It
could also be much more expensive, all depending.
