A lot of new fiber is still dark, waiting to replace that bad lead
cable. They ran two different colors of conduit for the RR backbone.
They told me one was for future use for long distance phone service.

When a line is put under the ground, they often put in blocks that
contain 4 built in tubes. Into these they pull new cables and have extras.
Some planning and some Rats, we didn't see that one!

The Telcos (and the CableCos) are all pushing large count fiber-
optic cables into the field, so every house can have it's own
dedicated fiber for high-speed data and video and etc. - But You DO
NOT Necessarily Want This!!!
It's a great idea for the Telco, will provide you with advanced
services and will save them tons of money over the long run - but they
want to serve you with that fiber only, and that is a VERY BAD IDEA.
They will present you with an agreement to install the fiber, and
buried in the fine print is that they get to remove all copper pairs
and serve you over the fiber only.
You must insist on one Plain Old Telephone Service line coming in to
your house on a metallic pair straight from the switchroom - write it
into the agreement, and ask them to send it to Legal... If for no
other reason than when the power fails that POTS line will still work,
with the 99.999% up-time reliability you've come to expect.
This is the line you put your burglar & fire alarm dialer on. This
is the line your boss can call you or you can call them at 2 AM, with
a reasonable chance that it will work.
The fiber field adapter box may well have a rechargeable backup
battery in it to keep minimal services running (one line dial-tone for
an hour or two) - but in 5 years when that battery goes bad, how long
do you think it'll take to get someone out to replace it? And how
many homeowners would even think to ask?

They aren't giving that option around here. It might be a mile of
copper, but everything is going fiber because of all the lightning
damage problems in Florida. You have two choices, old copper wth lots of
noise and outages, or new fiber. When enough people complain in an
area, everyone is switched over. The other option is no landline.

The no land line option is becoming very viable not that some cell
carriers are offering flat rate US plans, i.e. no minutes, no long
distance and no extra charges to and US number, land, cell or other.
As for the backup power for a fiber home terminal unit, any internal
battery it may have should only be a secondary backup. You need to have
your own "real" UPS covering that unit as well as your computer(s),
routers, aquarium, etc. all backed by a generator with an adequate fuel
supply.
