Emergency Broadcast/Alert System
AGENCY: Federal Communications Commission.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This Memorandum Opinion and Order addresses petitions for
reconsideration of the Federal Communications Commission's (FCC)
Emergency alert System rules (EAS). These rules were approved by the
FCC in 1994 to replace the Emergency Broadcast System (EBS). The
purpose of EAS is to improve emergency warnings and information using
broadcast stations and cable systems. The Memorandum Opinion and Order
makes some changes requested by the petitions and denies others, and
amends a number of the EAS rules.
EFFECTIVE DATE: December 6, 1995.
FOR FURTHER INFORMATION CONTACT:
EAS Staff, Compliance and Information Bureau, (202) 418-1220.
SUPPLEMENTARY INFORMATION: This is a synopsis of the Commission's
Memorandum Opinion and Order in FO Dockets 91-171/91-301, adopted
October 4, 1995, and released October 23, 1995.
The full text of this Commission Memorandum Opinion and Order is
available for inspection and copying during normal business hours in
the FCC's Public Reference Center (Room 239), 1919 M Street, NW.,
Washington DC 20554. The complete text of the Memorandam Opinion and
Order may also be purchased from the Commission's duplication
contractor, International Transcription Services, Inc., 2100 M Street
NW., suite 140, Washington, DC 20037, (202) 857-3800.
Synopsis of Memorandum Opinion and Order
The Federal Communications Commission (FCC) adopted a Memorandum
Opinion and Order addressing petitions for reconsideration of its
Emergency Alert System (EAS) rules. 47 CFR part 11. These rules were
approved by the Commission on November 10, 1994, in a Report and Order
which replaced the Emergency Broadcast System (EBS) with EAS. 59 FR
67090 (Dec. 28, 1994). The purpose of EAS is to use various
communications technologies, such as broadcast stations and cable
systems, to alert the public regarding national, state and local
emergencies. EAS, compared to EBS, includes more sources capable of
alerting the public and specifies new equipment standards and
procedures to improve alerting capabilities.
Petitions for reconsideration were submitted by Data Broadcasting
Corporation, Sage Alerting Systems, Inc., Federal Signal Corporation,
Delco Electronics Corporation, and the national Association of
Broadcasters. Also received were comments, oppositions to the petitions
for reconsideration, and replies to the oppositions.
The petition for reconsideration raised three major issues. The
first involved the Radio Broadcast Data System (RBDS). RBDS may be used
to send emergency warnings on the subcarrier of FM broadcast stations.
The Commission in its 1994 EAS Report and Order encouraged the use of
RBDS, but did not require it. Several petitions for reconsideration
requested that the FCC adopt rules specifying technical standards for
RBDS. The Commission in its Memorandum Opinion and Order declined to
establish standards since the use of RBDS is voluntary and mandated
standards would impede technological advances and innovation.
[[Page 55997]]
The second major issue concerned the present EAS requirement that
cable systems provide video interruption and an audio EAS message on
all channels. The National Association of Broadcasters claimed in its
petition for reconsideration that this violated the Copyright Act and
the Commission's ``must carry'' rules since they prohibit cable systems
from altering broadcast programming retransmitted on their systems. The
Commission responded that there was no conflict, and the EAS
requirement was permissible. The Commission further pointed out that
the Cable TV Act of 1992 requires cable systems to provide emergency
information.
The National Association of Broadcasters also requested that the
Commission postpone its deadline for broadcasters to install EAS
equipment from July 1, 1996, to July 1, 1997. The Commission agreed to
delay implementation until January 1, 1997.
The petitions for reconsideration and related comments also
requested a number of minor changes and clarifications in the EAS
rules. The Commission agreed to many, but not all, of the requested
changes. The rules that were changed in Part 11 (47 CFR Part 11) of the
FCC's rules are as follows:
--Section 11.33(a)(9). To avoid dead air during automated operation,
EAS decoders, after receive in an EAS header code, are required to
reset automatically if an End of Message (EOM) code is not received.
Reset time may not be less than two minutes.
--Section 11.33(a)(5). Clarifies the requirement that EAS decoders are
required to have a distinct and separate aural or visible means to
indicate when one of three listed conditions occurs such as the receipt
of a valid EAS header code.
--Section 11.34(c). Specifies that the required FCC equipment
authorization for combined EAS encoder/decoder devices is certification
instead of notification.
--Sections 11.51(1) (redesignated as Section 11.51(j) in the
amendments) and 11.52(e) are clarified, but not amended, by the
Memorandum Opinion and Order to reflect that EAS encoders and decoders
must be preprogrammed to transmit and accept eight event/originator
codes automatically with any possible combination of location codes
that are pertinent to the receiving station's coverage area or cable
system's community.
The mandatory event codes are EAN (Emergency Action Notification),
EAT (Emergency Action Termination), RMT (Required Monthly Test) and RWT
(Required Weekly Test). The mandatory originator codes are EAN
(Emergency Action Notification Network) and CIV (Civil Authorities) for
EAN and EAT event codes, and EAS (Broadcast Station or Cable System)
and CIV for the RMT and RWT event codes.
--Section 11.11. A note is added to this Section to make it clear that
FM translators are not required to have EAS equipment.
--Section 11.21. Because of concern that state and local officials
might misuse EAS, Section 11.21 of the rules is clarified so that only
procedures in state and local plans will be followed in EAS, and these
plans must be approved by the FCC's Compliance and Information Bureau.
The FCC will monitor the operation of EAS and publish a report before
July, 1 1998.
In addition, the FCC agreed to discuss with the Federal Emergency
Management Agency (FEMA) the possibility of financial assistance to
participants in implementing EAS.
The Commission declined to make several other requested rule
changes. The Commission, though, on its own made some minor revisions
and clarifications of its rules.
The amended rules become effective December 6, 1995. Furthermore,
the Commission will begin to accept applications from manufacturers of
EAS devices for FCC equipment authorization, namely, certification,
fourteen days after the amended EAS rules are released.
Rule Clarifications
The Commission has received numerous informal questions and
requests for clarification or correction of the rules. We will provide
interpretations and clarifications to the extent that the issues raised
do not go beyond the scope of the Report and Order or make substantive
changes to the decisions embodied in the Report and Order:
--Section 0.311(g) states that the zip code is 20054. This is amended
to be 20554.
--Section 11.11(b) states class D non-commercial FM and LPTV stations
are not required to comply with Section 11.32. This is amended to state
that they are not required to have or operate encoders which are
defined in Section 11.32.
--Section 11.31(a)(1) states that EAS characters are seven-bit ASCII.
This is amended to state that an eighth null bit is included for
transmission of a full eight-bit byte.
--Section 11.31(b) states that call signs that use a dash must instead
use a backslash in the EAS header code. This is amended to specify that
ASCII character 47 is the proper character for the backlash.
--Section 11.31(c) gives an example of the EAS protocol that has a
minor typographical error as printed in the Federal Register. This is
corrected to replace a ``+'' sign with a ``-'' sign.
--Section 11.33(a)(3)(i) states that decoders must provide a means to
record and store at least two minutes of audio or text messages. This
is clarified to state that the audio or text storage can be internal or
external to the decoder device. If no internal means for recording and
storing is manufactured internal to the decoder, then some means to
couple to an external device, such as an audio or digital jack
connection, must be supplied on the decoder.
--Section 11.33(a)(3)(ii) states that decoders must provide a means to
store a minimum of 10 preselected header codes. We clarify this rule to
specify that the decoder must store ten preselected event and
originator code combinations in addition to the eight mandatory code
combinations of tests and national activations. Also, we specify that
the decoder must store location codes pertaining to the broadcast
station coverage areas or the cable system's community in addition to
event and originator codes.
--Section 11.33(a)(11) states that header codes with an EAN Event code
that is received by the two decoder audio inputs must be able to
override all other EAS messages. This is amended to state that EAN
Event codes received by any of the decoder audio inputs must override
all other EAS messages, as it is possible that manufacturers may create
decoders with more than two audio inputs.
--Section 11.33(b)(2) states that the tolerance of the two-tone
frequencies in the decoder are 0.5 Hz above or below nominal. This is
corrected to state the tolerance is 5 Hz.
--Section 11.51(b) states that broadcast stations may transmit only the
EAS header and end-of-messages codes without the Attention Signal. This
is amended by adding a sentence stating that no Attention Signal is
warranted if the EAS message does not contain audio programming, such
as a Required Weekly Test.
--Section 73.1250(h) refers to Section 11.51 of the EAS rules. This is
amended to the more specific reference, Section 11.51(b).

Sec. 11.33 EAS Decoder.
(a) * * *
(3) * * *
(i) Record and store, either internally or externally, at least two
minutes of audio or text messages. A decoder manufactured without an
internal means to record and store audio or text must be equipped with
a means (such as an audio or digital jack connection) to couple to an
external recording and storing device.
(ii) Store at least 10 preselected event and originator header
codes, in addition to the eight mandatory event/originator codes for
tests and national activations, and store any preselected location
codes for comparison with incoming header codes. A non-preselected
header code that is manually transmitted must be stored for comparison
with later incoming header codes. The header codes of the last ten
received valid messages which still have valid time periods must be
stored for comparison with the incoming valid header codes of later
messages. These last received header codes will be deleted from storage
as their valid time periods expire.
* * * * *
(5) Indicators. EAS decoders must have a distinct and separate
aural or visible means to indicate when any of the following conditions
occurs:
(i) * * *
(ii) Preprogrammed header codes, such as those selected in
accordance with Sec. 11.52(d)(2) are received.
* * * * *
(9) Reset. There shall be a method to automatically or manually
reset the decoder to the normal monitoring condition. Operators shall
be able to select a time interval, not less than two minutes, in which
the decoder would automatically reset if it received an EAS header code
but not an end-of-message (EOM) code. Messages received with the EAN
Event codes shall disable the reset function so that lengthy audio
messages can be handled. The last message received with valid header
codes shall be displayed as required by paragraph (a)(4) of this
section before the decoder is reset.
* * * * *
(11) A header code with the EAN Event code specified in
Sec. 11.31(c) that is received through any of the audio inputs must
override all other messages.

11.33 may be combined and Certified as a single unit provided that the
unit complies with all specifications in this rule section.
* * * * *
10. A new Section 11.47 is added to read as follows:
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.
* * * * *

paragraph (a), adding a new sentence at the end of paragraph (b),
revising paragraph (c), removing paragraphs (f) and (i), and
redesignating the remaining paragraphs in alphabetical order to read as
follows:
Sec. 11.51 EAS code and Attention Signal Transmission requirements.
(a) * * * After January 1, 1998, the shortened Attention Signal may
only be used as an audio alert signal and the EAS codes will become the
minimum signalling requirement for National level messages and tests.
(b) * * * No Attention Signal is warranted for EAS messages that do
not contain audio programming, such as a Required Weekly Test.
(c) Effective January 1, 1997, all radio and television stations
shall transmit EAS messages in the main audio channel.

emergency messages of other broadcast stations during their hours of
operation. Effective January 1, 1997, all broadcast stations must
install and operate during their hours of operation, equipment capable
of receiving and decoding, either automatically or manually, the EAS
header codes, emergency messages and EOM code. The effective date for
subject cable systems is July 1, 1997.
Note to paragraph (a). After January 1, 1998, the two-tone
Attention Signal will not be used to actuate two-tone decoders but
will be used as an aural alert signal.
* * * * *
13. Section 11.61 is amended by revising paragraphs (a)(1)(i),
(a)(2)(i), and (a)(2)(ii)(A) to read as follows:
Sec. 11.61 Tests of EAS procedures.
