    I wonder what the tall tower in the background is. It 
looks like either an AM station or perhaps the support for a 
TV or FM antenna. Hard to tell from the photos.
    I don't know how long the microwave network stayed alive 
but wonder if satellites would  not have supplanted much of 
it long before optical fiber. For that matter, I wonder how 
long long lines kept copper in service.  My impression is 
that the copper stayed around until replaced by fiber.
