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 subject to this part, except as otherwise

protocol, as defined in § 11.31, to send and receive emergency alerts
in accordance with the effective dates listed above and in the

and digital broadcast stations that operate as satellites 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 § § 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.
