Sec.  11.11   The Emergency Alert System (EAS).

   (a) The EAS is composed of analog radio broadcast stations including AM, FM,
   and Low-power FM (LPFM) stations; digital audio broadcasting (DAB) stations,
   including digital AM, FM, and Low-power FM stations; analog television
   broadcast stations including Class A television (CA) and Low-power TV (LPTV)
   stations; digital television (DTV) broadcast stations, including digital CA
   and digital LPTV stations; analog cable systems; digital cable systems which
   are defined for purposes of this part only as the portion of a cable system
   that delivers channels in digital format to subscribers at the input of a
   Unidirectional Digital Cable Product or other navigation device; wireline
   video systems; wireless cable systems which may consist of Broadband Radio
   Service  (BRS),  or  Educational Broadband Service (EBS) stations; DBS
   services,  as  defined  in 47 CFR 25.701(a) (including certain Ku-band
   Fixed-Satellite Service Direct to Home providers); SDARS, as defined in 47
   CFR 25.201; participating broadcast networks, cable networks and program
   suppliers; and other entities and industries operating on an organized basis
   during emergencies at the National, State and local levels. These entities
   are referred to collectively as EAS Participants in this part, and are

   Participants must use a common EAS protocol, as defined in  Sec. 11.31, to send
   and receive emergency alerts in accordance with the effective dates listed
   above and in the following tables:

   2006, digital LPTV stations have the same requirements.

   ^3LPFM  stations  must install a decoder within one year after the FCC
   publishes in theFederal Registera public notice indicating that at least one
   decoder has been certified by the FCC. Effective December 31, 2006, digital
   LPFM stations have the same requirements.

   ^4Effective December 31, 2006, digital Class A TV stations have the same
   requirements.

   ^5Effective July 1, 1995, the two-tone signal must be 8–25 seconds.

   ^6Effective January 1, 1998, the two-tone signal may only be used to provide
   audio alerts to audiences before EAS emergency messages and the required

   or repeaters of a hub station (or common studio or control point if there is
   no hub station) and rebroadcast 100 percent of the programming of the hub
   station (or common studio or control point) may satisfy the requirements of
   this  part through the use of a single set of EAS equipment at the hub
   station (or common studio or control point) which complies with  Sec.  Sec. 11.32 and
   11.33.

   (c) For purposes of the EAS, Broadband Radio Service (BRS) and Educational
   Broadband Service (EBS) stations operated as part of wireless cable systems
   in accordance with subpart M of part 27 of this chapter are defined as
   follows:

   (1) A “wireless cable system” is a collection of channels in the BRS or EBS
   used to provide video programming services to subscribers. The channels may
   be licensed to or leased by the wireless cable system operator.

   (2) A “wireless cable operator” is the entity that has acquired the right to
   use the channels of a wireless cable system for transmission of programming
   to subscribers.

   (d) Local franchise authorities and cable television system operators may
   enter into mutual agreements that require the installation of EAS equipment
   before  the  required  dates  listed  in  the tables in paragraph (a).
   Additionally, local franchise authorities may use any EAS codes authorized
   by the FCC in any agreements.

   (e) 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.
