The local phone company estimates its average and peak loads and
allocates capacity as a business decision.  The percentage of
calls that can be trunk calls thus varies from place to place.

Trunk capacity increases exponentially with the number of trunk
lines, not linearly, as at first you might expect.  Figure out
how much traffic a highway can bear as a function of its width
in lanes.  That's basically the same thing, and some fancy math
helps (if you think statistical analysis is fancy math).

Cheers,
