Yes, that is true. In my statement though, i was relating to a security
breech or similar along the canada border, or other security factors,
not just natural disasters as you stated, but i see your point clearly.



One thing to consider when designing a system like the one above, is
that
it depends entirely on common carriers to provide the
interconnections
that support that wide area coverage. If you have a big disaster
(earthquake, supervolcano, or the like) that takes out your common
carrier links, by knocking all the microwave dish antennas out of
alignment, your really cool digital system DIES, BIGTIME, and no
amount
of support is going to bring it back quickly, untill those links are
fixed. This is a couple of months worth of work for a State wide
system.
