Sec. 11.1  Purpose.

    This part contains rules and regulations providing for an Emergency 
Alert System (EAS). The EAS provides the President with the capability 
to provide immediate communications and information to the general 
public at the National, State and Local Area levels during periods of 
national emergency. The rules in this part describe the required 
technical standards and operational procedures of the EAS for AM, FM and 
TV broadcast stations, cable systems and other participating entities. 
The EAS may be used to provide the heads of State and local government, 
or their designated representatives, with a means of emergency 
communication with the public in their State or Local Area.

Sec. 11.18  EAS Designations.

    (a) National Primary (NP) is a source of EAS Presidential messages.
    (b) Local Primary (LP) is a source of EAS Local Area messages. An LP 
source is responsible for coordinating the carriage of common emergency 
messages from sources such as the National Weather Service or local 
emergency management offices as specified in its EAS Local Area Plan. If 
it is unable to carry out this function, other LP sources in the Local 
Area may be assigned the responsibility as indicated in State and Local 
Area Plans. LP sources are assigned numbers (LP-1, 2, 3, etc.) in the 
sequence they are to be monitored by other broadcast stations in the 
Local Area.
    (c) State Primary (SP) is a source of EAS State messages. These 
messages can originate from the Governor or a designated representative 
in the State Emergency Operating Center (EOC) or State Capital. Messages 
are sent via the State Relay Network.
    (d) State Relay (SR) is a source of EAS State messages. It is part 
of the State Relay Network and relays National and State common 
emergency messages into Local Areas.
    (e) Participating National (PN) sources transmit EAS National, State 
or Local Area messages. The EAS transmissions of PN sources are intended 
for direct public reception.
    (f) Non-participating National (NN) sources have elected not to 
participate in the National level EAS and hold an authorization letter 
to that effect. Upon activation of the national level EAS, NN sources 
are required to broadcast the EAS codes, Attention Signal, the sign-off 
announcement in the EAS Operating Handbook and then stop operating. All 
NN sources are required to comply with Sec. 11.51, 11.52 and 11.61. 
They may transmit EAS State or Local Area messages at any time without 
prior notice.

Sec. 11.20  State Relay Network.

    This network is composed of State Relay (SR) sources, leased common 
carrier communications facilities or any other available communication 
facilities. The network distributes State EAS messages originated by the 
Governor or designated official. In addition to EAS monitoring, 
satellites, microwave, FM subcarrier or any other communications 
technology may be used to distribute State emergency messages.



Sec. 11.21  State and Local Area Plans and FCC Mapbook.

    EAS plans contain guidelines which must be followed by broadcast and 
cable personnel, emergency officials and National Weather Service (NWS) 
personnel to activate the EAS. The plans include the EAS header codes 
and messages that will be transmitted by key EAS sources (NP, LP, SP and 
SR). State and local plans contain unique methods of EAS message 
distribution such as the use of RBDS. The plans must be reviewed and 
approved by the Director, Office of Homeland Security, Enforcement 
Bureau, prior to implementation to ensure that they are consistent with 
national plans, FCC regulations, and EAS operation.
    (a) The State plan contains procedures for State emergency 
management and other State officials, the NWS, and broadcast and cable 
personnel to transmit emergency information to the public during a State 
emergency using the EAS.
    (b) The Local Area plan contains procedures for local officials or 
the NWS to transmit emergency information to the public during a local 
emergency using the EAS. Local plans may be a part of the State plan. A 
Local Area is a geographical area of contiguous communities or counties 
that may include more than one state.
    (c) The FCC Mapbook is based on the above plans. It organizes all 
broadcast stations and cable systems according to their State, EAS Local 
Area and EAS designation.

                    Subpart B_Equipment Requirements



Sec. 11.31  EAS protocol.

    (a) The EAS uses a four part message for an emergency activation of 
the EAS. The four parts are: Preamble and EAS Header Codes; audio 
Attention Signal; message; and, Preamble and EAS End Of Message (EOM) 
Codes.
    (1) The Preamble and EAS Codes must use Audio Frequency Shift Keying 
at a rate of 520.83 bits per second to transmit the codes. Mark 
frequency is 2083.3 Hz and space frequency is 1562.5 Hz. Mark and space 
time must be 1.92 milliseconds. Characters are ASCII seven bit 
characters as defined in ANSI X3.4-1977 ending with an eighth null bit 
(either 0 or 1) to constitute a full eight-bit byte.
    (2) The Attention Signal must be made up of the fundamental 
frequencies of 853 and 960 Hz. The two tones must be transmitted 
simultaneously. The Attention Signal must be transmitted after the EAS 
header codes.
    (3) The message may be audio, video or text.
    (b) The ASCII dash and plus symbols are required and may not be used 
for any other purpose. FM or TV call signs must use a slash ASCII 
character number 47 (/) in lieu of a dash.
    (c) The EAS protocol, including any codes, must not be amended, 
extended or abridged without FCC authorization.

[[Page 727]]

The EAS protocol and message format are specified in the following 
representation.

Examples are provided in FCC Public Notices.

[PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTT-JJJHHMM-LLLLLLLL-(one second pause)
[PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTT-JJJHHMM-LLLLLLLL-(one second pause)
[PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTT-JJJHHMM-LLLLLLLL-(at least a one 
second pause)
(transmission of 8 to 25 seconds of Attention Signal)
(transmission of audio, video or text messages)
(at least a one second pause)
[PREAMBLE]NNNN (one second pause)
[PREAMBLE]NNNN (one second pause)
[PREAMBLE]NNNN (at least one second pause)

    [PREAMBLE] This is a consecutive string of bits (sixteen bytes of AB 
hexadecimal [8 bit byte 10101011]) sent to clear the system, set AGC and 
set asynchronous decoder clocking cycles. The preamble must be 
transmitted before each header and End Of Message code.
    ZCZC--This is the identifier, sent as ASCII characters ZCZC to 
indicate the start of ASCII code.
    ORG--This is the Originator code and indicates who originally 
initiated the activation of the EAS. These codes are specified in 
paragraph (d) of this section.
    EEE--This is the Event code and indicates the nature of the EAS 
activation. The codes are specified in paragraph (e) of this section. 
The Event codes must be compatible with the codes used by the NWS 
Weather Radio Specific Area Message Encoder (WRSAME).
    PSSCCC--This the Location code and indicates the geographic area 
affected by the EAS alert. There may be 31 Location codes in an EAS 
alert. The Location code uses the Federal Information Processing 
Standard (FIPS) numbers as described by the U.S. Department of Commerce 
in National Institute of Standards and Technology publication FIPS PUB 
6-4. Each state is assigned an SS number as specified in paragraph (f) 
of this section. Each county and some cities are assigned a CCC number. 
A CCC number of 000 refers to an entire State or Territory. P defines 
county subdivisions as follows: 0 = all or an unspecified portion of a 
county, 1 = Northwest, 2 = North, 3 = Northeast, 4 = West, 5 = Central, 
6 = East, 7 = Southwest, 8 = South, 9 = Southeast. Other numbers may be 
designated later for special applications. The use of county 
subdivisions will probably be rare and generally for oddly shaped or 
unusually large counties. Any subdivisions must be defined and agreed to 
by the local officials prior to use.
    +TTTT--This indicates the valid time period of a message in 15 
minute segments up to one hour and then in 30 minute segments beyond one 
hour; i.e., +0015, +0030, +0045, +0100, +0430 and +0600.
    JJJHHMM--This is the day in Julian Calendar days (JJJ) of the year 
and the time in hours and minutes (HHMM) when the message was initially 
released by the originator using 24 hour Universal Coordinated Time 
(UTC).
    LLLLLLLL--This is the identification of the broadcast station, cable 
system, MDS/MMDS/ITFS station, NWS office, etc., transmitting or 
retransmitting the message. These codes will be automatically affixed to 
all outgoing messages by the EAS encoder.
    NNNN--This is the End of Message (EOM) code sent as a string of four 
ASCII N characters.

    (d) The only originator codes are:

System (RBDS), NWR, satellite, public switched telephone network, or any

[[Page 730]]

other source that uses the EAS protocol.
    (2) Valid codes. There must be a means to determine if valid EAS 
header codes are received and to determine if preselected header codes 
are received.
    (3) Storage. Decoders must provide the means to:
    (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 ten preselected event and originator header 
codes, in addition to the seven 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 for later messages. 
These last received header codes will be deleted from storage as their 
valid time periods expire.
    (4) Display and logging. A visual message shall be developed from 
any valid header codes for tests and national activations and any 
preselected header codes received. The message shall include the 
Originator, Event, Location, the valid time period of the message and 
the local time the message was transmitted. The message shall be in the 
primary language of the broadcast station or cable system and be fully 
displayed on the decoder and readable in normal light and darkness. All 
existing and new models of EAS decoders manufactured after August 1, 
2003 must provide a means to permit the selective display and logging of 
EAS messages containing header codes for state and local EAS events. 
Effective May 16, 2002, broadcast stations, cable systems and wireless 
cable systems may upgrade their decoders on an optional basis to include 
a selective display and logging capability for EAS messages containing 
header codes for state and local events. Broadcast stations, cable 
systems and wireless cable systems which replace their decoders after 
February 1, 2004 must install decoders that provide a means to permit 
the selective display and logging of EAS messages containing header 
codes for state and local EAS events.
    (5) Indicators. EAS decoders must have a distinct and separate aural 
or visible means to indicate when any of the following conditions 
occurs:
    (i) Any valid EAS header codes are received as specified in Sec. 
11.33(a)(10).
    (ii) Preprogrammed header codes, such as those selected in 
accordance with Sec. 11.52(d)(2) are received.
    (iii) A signal is present at each audio input that is specified in 
Sec. 11.33(a)(1).
    (6) Program Data Retention. The program data must be retained even 
with power removed.
    (7) Outputs. Decoders shall have the following outputs: a data port 
or ports (RS-232C with standard protocol and 1200 baud rate) where 
received valid EAS header codes and received preselected header codes 
are available; one audio port that is capable of monitoring each decoder 
audio input; and, an internal speaker to enable personnel to hear audio 
from each input.
    (8) Decoder Programming. Access to decoder programming shall be 
protected by a lock or other security measures and be configured so that 
authorized personnel can readily select and program the EAS Decoder with 
preselected Originator, Event and Location codes for either manual or 
automatic operation.
    (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.

[[Page 731]]

    (10) Message Validity. An EAS Decoder must provide error detection 
and validation of the header codes of each message to ascertain if the 
message is valid. Header code comparisons may be accomplished through 
the use of a bit-by-bit compare or any other error detection and 
validation protocol. A header code must only be considered valid when 
two of the three headers match exactly. Duplicate messages must not be 
relayed automatically.
    (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.
    (b) Attention Signal. EAS Decoders at broadcast stations shall have 
detection and activation circuitry that will demute a receiver upon 
detection of the two audio tones of 853 Hz and 960 Hz. To prevent false 
responses, decoders designed to use the two tones for broadcast receiver 
demuting shall comply with the following:
    (1) Time Delay. A minimum time delay of 8 but not more than 16 
seconds of tone reception shall be incorporated into the demuting or 
activation process to insure that the tones will be audible for a period 
of at least 4 seconds. After July 1, 1995, the time delay shall be 3-4 
seconds.
    (2) Operation Bandwidth. The decoder circuitry shall not respond to 
tones which vary more than 5 Hz from each of the 
frequencies, 853 Hz and 960 Hz.
    (3) Reset Ability. The decoder shall have a means to manually or 
automatically reset the associated broadcast receiver to a muted state.
    (c) Decoders shall be capable of operation within the tolerances 
specified in this section as well as those in Sec. 11.32 (b), (c) and 
(d).

                     Subpart D_Emergency Operations



Sec. 11.51  EAS code and Attention Signal Transmission requirements.

    (a) Broadcast stations must transmit, either automatically or 
manually, national level EAS messages and required tests by sending the 
EAS header codes, Attention Signal, emergency message and End of Message 
(EOM) using the EAS Protocol. The Attention Signal must precede any 
emergency audio message. 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) When relaying EAS messages, broadcast stations and cable systems 
and wireless cable systems may transmit only the EAS header codes and 
the EOM code without the Attention Signal and emergency message for 
State and local emergencies. Television stations, cable systems and 
wireless cable systems should ensure that pauses in video programming 
before EAS message transmission do not cause television receivers to 
mute EAS audio messages. No Attention Signal is required 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.
    (d) By the above date, television stations shall transmit a visual 
message containing the Originator, Event, Location and the valid time 
period of an EAS message. If the message is a video crawl, it shall be 
displayed at the top of the television screen or where it will not 
interfere with other visual messages.
    (e) Class D non-commercial educational FM stations as defined in 
Sec. 73.506 of this chapter, Low Power FM (LPFM) stations as defined in 
Sec. Sec. 73.811 and 73.853 of this chapter, and low power TV (LPTV) 
stations as defined in Sec. 74.701(f) of this chapter are not required 
to have equipment capable of generating the EAS codes and Attention 
Signal specified in Sec. 11.31.
    (f) Broadcast station equipment generating the EAS codes and the 
Attention Signal shall modulate a broadcast station transmitter so that 
the signal broadcast to other broadcast stations and cable systems and 
wireless cable systems alerts them that the EAS is being activated or 
tested at the National, State or Local Area level. The minimum level of 
modulation for EAS codes, measured at peak modulation levels using the 
internal calibration output required in Sec. 11.32(a)(4), shall 
modulate the transmitter at the maximum possible level, but in no case 
less than 50% of full channel modulation limits. Measured at peak 
modulation levels, each of the Attention Signal tones shall be 
calibrated separately to modulate the transmitter at no less than 40%. 
These two calibrated modulation levels shall have values that are within 
1 dB of each other.
    (g) Effective October 1, 2002, cable systems with fewer than 5,000 
subscribers per headend and wireless cable

[[Page 735]]

systems with fewer than 5,000 subscribers shall transmit EAS audio 
messages in the same order specified in paragraph (a) of this section on 
at least one channel. The Attention Signal may be produced from a 
storage device. Additionally, cable systems and wireless cable systems 
must:
    (1) Install, operate, and maintain equipment capable of generating 
the EAS codes. The modulation levels for the EAS codes and Attention 
Signal shall comply with the aural signal requirements in Sec. 76.605 
of this chapter,
    (2) Provide a video interruption and an audio alert message on all 
channels. The audio alert message must state which channel is carrying 
the EAS video and audio message,
    (3) Cable systems and wireless cable systems shall transmit a visual 
EAS message on at least one channel. The message shall contain the 
Originator, Event, Location, and the valid time period of the EAS 
message. If the visual message is a video crawl, it shall be displayed 
at the top of the subscriber's television screen or where it will not 
interfere with other visual messages.
    (4) Cable systems and wireless cable systems may elect not to 
interrupt EAS messages from broadcast stations based upon a written 
agreement between all concerned. Further, cable systems and wireless 
cable systems may elect not to interrupt the programming of a broadcast 
station carrying news or weather related emergency information with 
state and local EAS messages based on a written agreement between all 
parties.
    (h) Effective December 31, 1998, cable systems with 10,000 or more 
subscribers; and, effective October 1, 2002, cable systems serving 5,000 
or more, but less than 10,000 subscribers per headend and wireless cable 
systems with 5,000 or more subscribers; shall transmit EAS audio 
messages in the same order specified in paragraph (a) of this section. 
The Attention Signal may be produced from a storage device. 
Additionally, after the dates indicated, these cable systems and 
wireless cable systems must:
    (1) Install, operate, and maintain equipment capable of generating 
the EAS codes. The modulation levels for the EAS codes and Attention 
Signal for cable systems shall comply with the aural signal requirements 
in Sec. 76.605 of this chapter. This will provide sufficient signal 
levels to operate cable subscriber television and radio receivers 
equipped with EAS decoders and to audibly alert subscribers. Wireless 
cable systems shall also provide sufficient signal levels to operate 
subscriber television and radio receivers equipped with EAS decoders and 
to audibly alert subscribers.
    (2) The cable systems and wireless cable systems in this paragraph 
(h) shall transmit the EAS audio message required in paragraph (a) of 
this section on all downstream channels.
    (3) The cable systems and wireless cable systems in this paragraph 
(h) shall transmit the EAS visual message on all downstream channels. 
The visual message shall contain the Originator, Event, Location and the 
valid time period of the EAS message. These are elements of the EAS 
header code and are described in Sec. 11.31. If the visual message is a 
video crawl, it shall be displayed at the top of the subscriber's 
television screen or where it will not interfere with other visual 
messages.
    (4) Cable systems and wireless cable systems may elect not to 
interrupt EAS messages from broadcast stations based upon a written 
agreement between all concerned. Further, cable systems and wireless 
cable systems may elect not to interrupt the programming of a broadcast 
station carrying news or weather related emergency information with 
state and local EAS messages based on a written agreement between all 
parties.
    (i) If manual interrupt is used as authorized in paragraph (k) of 
this section, EAS Encoders must be located so that broadcast station, 
cable system or wireless cable system staff, at normal duty locations, 
can initiate the EAS code and Attention Signal transmission.
    (j) Broadcast stations, and cable systems and wireless cable systems 
that are co-owned and co-located with a combined studio or control 
facility, (such as an AM and FM licensed to the same entity and at the 
same location or a cable headend serving more than one system) may 
provide the EAS transmitting requirements contained

[[Page 736]]

in this section for the combined stations or cable systems or wireless 
cable systems with one EAS Encoder. The requirements of Sec. 11.32 must 
be met by the combined facility.
    (k) Broadcast stations and cable systems and wireless cable systems 
are required to transmit all received EAS messages in which the header 
code contains the Event codes for Emergency Action Notification (EAN), 
Emergency Action Termination (EAT), and Required Monthly Test (RMT), and 
when the accompanying location codes include their State or State/
county. These EAS messages shall be retransmitted unchanged except for 
the LLLLLLLL-code which identifies the broadcast station, cable system, 
wireless cable system, or other entity retransmitting the message. See 
Sec. 11.31(c). If an EAS source originates an EAS message with the 
Event codes in this paragraph, it must include the location codes for 
the State and counties in its service area. When transmitting the 
required weekly test, broadcast stations and cable systems and wireless 
cable systems shall use the event code RWT. The location codes are the 
state and county for the broadcast station city of license or cable 
system or wireless cable system community or city. Other location codes 
may be included upon approval of broadcast station, cable system or 
wireless cable system management. EAS messages may be transmitted 
automatically or manually.
    (1) Automatic interrupt of programming and transmission of EAS 
messages are required when facilities are unattended. Automatic 
transmissions must include a permanent record that contains at a minimum 
the following information: Originator, Event, Location and valid time 
period of the message. The decoder performs the functions necessary to 
determine which EAS messages are automatically transmitted by the 
encoder.
    (2) Manual interrupt of programming and transmission of EAS messages 
may be used. EAS messages with the EAN Event code must be transmitted 
immediately and Monthly EAS test messages within 60 minutes. All actions 
must be logged and include the minimum information required for EAS 
video messages.
    (l) Broadcast stations and cable systems and wireless cable systems 
may employ a minimum delay feature, not to exceed 15 minutes, for 
automatic interruption of EAS codes. However, this may not be used for 
the EAN event which must be transmitted immediately. The delay time for 
an RMT message may not exceed 60 minutes.
    (m) Either manual or automatic operation of EAS equipment may be 
used at broadcast stations and cable systems and wireless cable systems 
that use remote control. If manual operation is used, an EAS decoder 
must be located at the remote control location and it must directly 
monitor the signals of the two assigned EAS sources. If direct 
monitoring of the assigned EAS sources is not possible at the remote 
location, automatic operation is required. If automatic operation is 
used, the remote control location may be used to override the 
transmission of an EAS alert. Broadcast stations and cable systems and 
wireless cable systems may change back and forth between automatic and 
manual operation.

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 dates for 
cable and wireless cable systems to install and operate EAS equipment 
are set forth in Sec. 11.11.

    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.


[[Page 737]]


    (b) If manual interrupt is used as authorized in Sec. 11.51(j)(2), 
decoders must be located so that operators at their normal duty stations 
at broadcast stations and cable systems and wireless cable systems can 
be alerted immediately when EAS messages are received.
    (c) Broadcast stations and cable systems and wireless cable systems 
that are co-owned and co-located with a combined studio or control 
facility (such as an AM and FM licensed to the same entity and at the 
same location or a cable headend serving more than one system) may 
comply with the EAS monitoring requirements contained in this section 
for the combined station or system with one EAS Decoder. The 
requirements of Sec. 11.33 must be met by the combined facility.
    (d) Broadcast stations and cable systems and wireless cable systems 
must monitor two EAS sources. The monitoring assignments of each 
broadcast station and cable system and wireless cable system are 
specified in the State EAS Plan and FCC Mapbook. They are developed in 
accordance with FCC monitoring priorities.
    (1) If the required EAS sources cannot be received, alternate 
arrangements or a waiver may be obtained by written request to the FCC's 
EAS office. In an emergency, a waiver may be issued over the telephone 
with a follow up letter to confirm temporary or permanent reassignment.
    (2) Broadcast station and cable system and wireless cable system 
management shall determine which header codes will automatically 
interrupt their programming for State and Local Area emergency 
situations affecting their audiences.
    (e) Broadcast stations and cable systems and wireless cable systems 
are required to interrupt normal programming either automatically or 
manually when they receive an EAS message in which the header code 
contains the Event codes for Emergency Action Notification (EAN), 
Emergency Action Termination (EAT), and Required Monthly Test (RMT) for 
their State or State/county location.
    (1) Automatic interrupt of programming is required when facilities 
are unattended. Automatic operation must provide a permanent record of 
the EAS message that contains at a minimum the following information: 
Originator, Event, Location and valid time period of the message.
    (2) Manual interrupt of programming and transmission of EAS messages 
may be used. EAS messages with the EAN Event code must be transmitted 
immediately and Monthly EAS test messages within 60 minutes. All actions 
must be logged and recorded. Decoders must be programmed for the EAN and 
EAT Event header codes for National level emergencies and the RMT and 
RWT Event header codes for required monthly and weekly tests, with the 
appropriate accompanying State and State/county location codes.

Sec. 11.53  Dissemination of Emergency Action Notification.

    Initiation of the EAN by any one of the following sources is 
sufficient to begin the emergency actions in Sec. 11.54.
    (a) National Level. The EAN is issued by the White House. The EAN 
message is sent from a government origination point to broadcast 
stations and other entities participating in the PEP system. It is then 
disseminated via:
    (1) Radio and television broadcast stations.
    (2) Cable systems and wireless cable systems.
    (3) Other entities voluntarily participating in EAS.
    (b) State level and Local Area levels. EAN dissemination 
arrangements at these levels originate from State and local governments 
in accordance with State and Local Area plans.
    (c) Broadcast stations must, prior to commencing routine operation 
or originating any emissions under program test, equipment test, 
experimental, or other authorizations, determine whether the EAS has 
been activated by monitoring the assigned EAS sources.
