Sec. 90.471  Points of operation in internal transmitter control 
          systems.

    The transmitting facilities of the licensee may be operated from 
fixed positions located on premises controlled by the licensee. The 
fixed position may be part of a private telephone exchange or it may be 
any position in a closed or limited access communications facility 
intended to be used by employees of the licensee for internal 
communications and transmitter control purposes. Operating positions in 
internal transmitter control systems are not synonymous with dispatch 
points (See Sec. 90.467) nor with telephone positions which are part of 
the public, switched telephone network; and the scheme of regulation is 
to be considered and treated as being different. See Secs. 90.485 
through 90.489.
