Sec.  3.46   Use of gold francs.

   An accounting authority must accept accounts presented to it from foreign
   administrations in gold francs. These gold francs must be converted on the
   date of receipt of the bill to the applicable Special Drawing Right (SDR)
   rate  (as  published  by the International Monetary Fund) on that date
   utilizing  the  linking  coefficient  of 3.061 gold francs = 1 SDR. An
   equivalent  amount  in  U.S.  dollars  must  be  paid  to  the foreign
   administration. Upon written concurrence by the FCC, an accounting authority
   may make separate agreements, in writing, with foreign administrations or
   their agents for alternative settlement methods, in accordance with ITU-T
   Recommendation D.195.
