As far as I know, AT&T is the only carrier which maintained
the ability to rebuild an entire central office from a "smoking
hole in the ground." Last year the program budget was in danger
of being cut, and the program eliminated because it had never
been needed. It was an expense, which couldn't be justified.
I spoke with one of the managers last year, and he said "It
would only take one catastrophe to pay for my entire budget."
I don't believe he was thinking of this.
