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; 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 provided herein. These rules in this part are effective
on December 31, 2006 for DTV, DAB, digital cable and SDARS providers, and on
May 31, 2007 for DBS providers. At a minimum EAS 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 in this paragraph
and in the following tables:

give the channel where the EAS messages are carried and be repeated for the
duration of the EAS message.

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) Organizations using other communications systems or technologies such as
low earth orbit satellite systems, paging, computer networks, etc. may join
the EAS on a voluntary basis by contacting the FCC. Organizations that
choose to voluntarily participate must comply with the requirements of this
