Sec.  22.733   Priority of service.

   Within the Rural Radiotelephone Service, the channels listed in  Sec. 22.725 are
   intended primarily for use in rendition of public message service between
   rural subscriber and central office stations and to provide radio trunking
   facilities between central offices. The channels may also be used, however,
   for the rendition of private leased-line communication service provided that
   such usage would not reduce or impair the extent or quality of communication
   service that would be available, in the absence of private leased-line
   service, to the general public receiving or subsequently requesting public
   message service from a central office.
