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, Mike -------
