§  11.47   Optional use of other communications methods and systems.

   (a) Analog and digital broadcast stations may additionally transmit EAS
   messages through other communications means. For example, on a
   voluntary basis, FM stations may use subcarriers to transmit the EAS
   codes including 57 kHz using the RBDS standard produced by the National
   Radio Systems Committee (NRSC) and television stations may use
   subsidiary communications services.

   (b) Other technologies and public service providers, such as low earth
   orbiting satellites, that wish to participate in the EAS may contact
   the FCC's Public Safety and Homeland Security Bureau or their State
   Emergency Communications Committee for information and guidance.
