So that no readers of this forum get a completely wrong impression,
let me add 0.02 worth of information.

It may once have been true that U.S. Sprint, or its predecessor
companies, leased most of its long-distance circuits from AT&T or
other carriers.  But it is probably safe to suppose that Sprint's
circuits, at least on high-traffic routes, are now its own.

 From 1985 to 1988, I worked for Siecor Corporation, a joint venture
of Siemens A.G. and Corning Glass Works.  A major part of Siecor's
business is the manufacture of single-mode fiber-optic cable for
long-haul telecommunication.  I know that during that period U.S.
Sprint bought quite a lot of such cable from Siecor.  (Many
"fiber-kilometers", as we say in the trade.) This cable, and probably
cable from other suppliers, went into the ground across the United
States and forms the backbone of the network that is touted in
advertisements.
