make a phone call during a fiber cut, why can't you process an

Well, sometimes you can't make a phone call during a fiber cut.
During the Sprint outage a couple of weeks ago the first thing
we noticed were strange PSTN outages.  High-and-dry and reorder
for the most part with an occasional "circuits busy" intercept.
The cut didn't have any significant effect on IP as far as we
could tell (but we're not a Sprint customer).
