Sec. 11.47  Optional use of other communications methods and systems.

    (a) Broadcast stations may additionally transmit EAS messages 
through other communications means than the main audio channel. 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 DBS, 
low earth orbiting satellites, etc., that wish to participate in the EAS 
may contact the FCC's EAS office or their State Emergency Communication 
Committee for information and guidance.
