Sec.  51.709   Rate structure for transport and termination.

   (a) In state proceedings, a state commission shall establish rates for the
   transport and termination of telecommunications traffic that are structured
   consistently  with  the  manner  that  carriers incur those costs, and
   consistently with the principles in  Sec.  Sec. 51.507 and 51.509.

   (b) The rate of a carrier providing transmission facilities dedicated to the
   transmission of traffic between two carriers' networks shall recover only
   the  costs  of  the  proportion  of  that  trunk  capacity  used by an
   interconnecting carrier to send traffic that will terminate on the providing
   carrier's network. Such proportions may be measured during peak periods.
