Ok, given that, how do suburban areas today, which have enormous
population growth, deal with such issues? Those areas never had fire
call boxes.

And what about the many cities that have removed their callboxes?

I can't help but wonder that the huge decline in price of electronic
equipment has enabled the basic landline phonecos to have far more
spare capacity than it once did. Years ago it was simply too
expensive to waste trunks and switchgear, no longer. (Same reason a
$500 PC today is many times more powerful than a $2,000 PC of 25 years
ago). Thus, I think the occurences of no dial tone or lack of trunks
would be extremely rare today.

Having a 911 center overwhelmed with incoming calls is another story.

You simply "don't know what you don't know."

I routinely -- as in several times a week -- encounter 'unable to complete
your call' intercept messages and/or fast busy.

Not getting immediate dial-tone _is_ rarer today. Attributable in part
to _fewer_ residences per exchange (more multi-line residences). when
"sh*t happens" you're not going to have three separate people in the same
house picking up separate lines and all calling 911 -- nor all making calls
to see if grandma is ok.

'digit decoders' have gotten cheaper, it's easier to justify higher ratios
per exchange.

Trunks, on the other hand, are still relatively "expensive". and always
will be. Before you consider things like '3-way' calling, that can tie
up more trunks than premise lines.
