EBS EAS Continued, Although the EBS system was established for national messages many broadcasters and local officials recognized that. the system could be used to notify listeners about local emergency situations too Between 1976 and the beginning of. 1996 the FCC had received 20 341 reported activations of EBS Approximately 85 of these activations were for. weather related emergencies The number of activations was most assuredly higher as stations were not required to. report their usage of the system, The system was never used for a nuclear emergency though it was activated more than 20 000 times between 1976 and. 1996 to broadcast civil emergency messages and warnings of severe weather hazards. Under the EBS program equipment that allowed the President to reach the public through their local. broadcasters was required at broadcast stations licensed by the FCC This equipment produced what was. commonly called a two tone signal the frequencies 853Hz and 960Hz played simultaneously that was broadcast by stations. on the main audio channel and served the dual purpose of getting the listeners attention and activating other EBS. equipment in the listening area Upon activation of the EBS equipment a station would listen and record the. accompanying audio message and could then retransmit this message for their audience In general EBS equipment. could do little more than reproduce the dual tone signal and record the messages it receives upon activation EBS. equipment can only monitor one source for alerts Once a station received an EBS message it must broadcast the EBS. message and two tone signal in order for the next station to receive the information If a station failed to activate their. EBS equipment the chain will be broken and a segment of the population will not receive the emergency information. through EBS, An order to activate the EBS at the national level would have originated with the President and been relayed via the. White House Communications Agency duty officer to one of two origination points either the Aerospace Defense. Command or the Federal Preparedness Agency as the system stood in 1978 Participating telecommunications. common carriers radio and television networks the Associated Press and United Press International would receive and. authenticate by means of code words an Emergency Action Notification via an EAN teletypewriter network designed. specifically for this purpose These recipients would relay the EAN to their subscribers and affiliates. The release of the EAN by the ADC or FPA would initiate a process by which the common carriers would link otherwise. independent networks such as ABC CBS and NBC into a single national network that even independent stations could. receive programming from Broadcast stations would have used the two tone Attention Signal on their assigned. broadcast frequency to alert other broadcast stations to stand by for a message from the President Note that the. transmission of programming on a broadcast station s assigned frequency and the fact that television networks stations. could participate distinguished EBS from CONELRAD EBS radio stations would not transmit on 640 or 1240 AM and. television stations would carry the same audio program as AM radio stations. An EBS slide from the late 1980s, In 1996 a law was passed to replace the Emergency Broadcast System EBS with the new fangled digital. Emergency Alert System and EBS was officially retired in January 1998 isn t there always an upgrade. This resulted in a temporary suspension of the mandatory tests This temporary suspension ended up lasting. much longer as many stations balked at having to go digital A compromise was reached in 2008 to allow. media stations at a non national level to remain analog if they choose to do so and took advantage of the. EBS EAS Continued, elaborate analog digital messaging systems operated by the National Weather Service After many delays the.
final deadline to convert to digital was 2010 and the first test of the new digital EAS system took place on. November 9 2012 which failed miserably, This new system provides access to broadcast stations cable systems and participating satellite programmers for the. transmission of emergency messages and less obtrusive weekly tests The EAS uses digital codes developed by the. National Weather Service NWS NWS offices can originate coded messages that are area specific and will only activate. EAS decoders and send emergency warnings to people in the affected geographic area. What is EAS, The Emergency Alert System EAS is a national warning system in the United States put into place in 1996 98. superseding the Emergency Broadcast System EBS and the CONELRAD System. The Federal Communications Commission FCC designed the Emergency Alert System EAS so officials can supposedly. quickly send out important emergency information targeted to a specific area. The official EAS is designed to enable the President of the United States to speak to the United States within 10 minutes. this official federal EAS has never been activated The EAS regulations and standards are governed by the Public Safety and. Homeland Security Bureau of the FCC Each state and several territories have their own EAS plan. The EAS covers AM FM and Land Mobile Radio Service as well as VHF UHF and cable television including low power. stations Digital television and cable providers along with Sirius XM satellite radio IBOC DAB and digital radio. broadcasters have been required to participate in the EAS since December 31 2006 DirecTV Dish Network and all other. DBS providers have been required to participate since May 31 2007. After conducting extensive tests of competing technologies the FCC ruled that the EAS would be a digital based. automated system and use coding protocols similar to NOAA Weather Radio NWR Specific Area Message Encoding. EBS EAS Continued, EAS sends out alerts not just to broadcast media but also to cable television satellites pagers Direct Broadcast Satellite. High Definition Television and Video Dial Tone EAS also accounts for the needs of special populations such as the deaf. and those with special language requirements, While NWR SAME is the National Weather Service s NWS primary entry into EAS you can receive EAS messages via. radio and TV stations and many other media FCC rules also requires broadcasters to monitor at least two independent. sources for emergency information ensuring that emergency information is received and delivered to viewers and. Under the EAS guidelines each state has formed a State Emergency Communications Committee SECC The SECC is. chaired by a broadcast and cable representative who was nominated by the SECC membership and appointed by the. FCC Duties of the SECC include,Presiding over training and workshop sessions.
Acting as liaison with the National Advisory Committee and Local Emergency Communications Committees. Performing studies to improve emergency communications. Developing the state EAS plan for broadcast and cable media. The LECC support the SECC mission on a local level The number of LECCs varies widely from state to state Each LECC is. responsible for an area about the size of a typical county LECC members include broadcasters cable operators. emergency management officials other technological personnel and amateur radio operators utility companies in the. service area and others who have a responsibility or interest in local emergency communications. EAS has become part of IPAWS the Integrated Public Alert and Warning System a program of Federal Emergency. Management Agency FEMA EAS is jointly coordinated by FEMA the Federal Communications Commission FCC and. the National Weather Service NWS, Messages in the EAS are composed of four parts a digitally encoded SAME header an attention signal an audio. announcement and a digitally encoded end of message marker. In a The New York Times article correction printed January 3 2002 the lack of news coverage by station WNYC FM New. York was explained by the destruction of its broadcast transmitters with the collapse of the World Trade Center north. tower on 9 11 No president has ever used the current EAS system or its technical predecessors in the last 50 years. EBS EAS Continued, despite the Soviet missile crisis a presidential assassination the Oklahoma City bombing major earthquakes and three. recent high alert terrorist warnings said Michael K Powell the then chairman of the Federal Communications. Commission which oversees the Emergency Alert System pointed to the ubiquitous media environment arguing that. the system was in effect scooped by CNN MSNBC Fox News Channel and other channels FEMA activates the alert. system nationally at the behest of the White House on 34 50 000 watt stations that reach 98 percent of Americans. Beyond that the current Emergency Alert System signal is an audio message only which pre empts all programming. so that viewers who were watching color images of the trade center on Sept 11 would have been able to see only a. screen with a generic text message along with a presidential voice over if an emergency message had been activated. Other than the on screen scrolling message accompanying the initial activation the Federal Communications System EAS. TV Handbook 2007 does not include any sort of visual element Under the SAME protocol precise emergency. information would be delivered aurally, The FCC requires all broadcast stations and multichannel video programming distributors MVPD to install and maintain. EAS decoders and encoders at their control points or headends Hence the push for the nation to go digital in November of. 2010 These decoders continuously monitor the signals from other nearby broadcast stations for EAS messages For. reliability at least two other source stations must be monitored one of which must be a designated local primary. Stations are to retain the latest version of the EAS handbook. Stations are required by law to keep full logs of all received and transmitted EAS messages Logs may be kept by hand. but are usually kept automatically by a small receipt printer in the encoder decoder unit Logs may also be kept. electronically inside the unit as long as there is access to an external printer or method to transfer them to a personal. In addition to the audio messages transmitted by radio stations television stations must also transmit a visual message. A text crawl is displayed at the top of the screen that contains all of the information encoded in the initial SAME. header A color coded crawl system is often used where the color signifies the priority of the message Some. television stations transmit only the visual message which is outside of the requirements A television station may be. used for monitoring by another station and thus the audio is necessary. A cable system s visual message displayed during a required test In actual emergencies this screen would display the. FCC mandated visual message accompanying the alert. Upon reception of an alert a station must relay EAN Emergency Action Notification and EAT Emergency Action Termination. messages immediately US FCC 7 Stations traditionally have been allowed to opt out of relaying other alerts such as. severe weather and child abduction emergencies AMBER Alerts if they so choose Under new rules published on July 12. 2007 the FCC requires all stations to relay state and local alerts that are approved by their states governors as per the. approval of the CAP standard, Some stations may be non participating and do not relay messages Instead they transmit a message instructing. listeners viewers to tune to another station for the information and they must then suspend their operation EAS. equipment must be FCC certified for use, The number of event types in the national system has grown to eighty At first almost all but three of the events civil.
emergency message immediate evacuation and emergency action notification national emergency were weather related such. as a tornado warning Since then several classes of non weather emergencies have been added including in most. states the AMBER Alert System for child abduction emergencies. EBS EAS Continued, In 2004 the FCC issued a Notice of Proposed Rulemaking seeking comment on whether EAS in its present form is the. most effective mechanism for warning the American public of an emergency and if not how EAS can be improved such. as mandatory text messages to cell phones regardless of subscription As noted above rules implemented by the FCC. on July 12 2007 provisionally endorse replacing the SAME protocol with CAP and allow governors to compel universal. activation of the system within their own states, What is IPAWS Integrated Public Alert and Warning System. Executive Order 13407 of June 26 2006 Public Alert and Warning System By the authority vested in me as President by. the Constitution and the laws of the United States of America including the Robert T Stafford Disaster Relief and. Emergency Assistance Act as amended 42 U S C 5121 et seq and the Homeland Security Act of 2002 as amended 6. U S C 101 et seq http en wikisource org wiki Executive Order 13407 and established as policy the requirement for the. United States to have an effective reliable integrated flexible and comprehensive system to alert and warn the. American people, FEMA is designated within the Department of Homeland Security to implement the policy of the United States for a. public alert and warning system as outlined in Executive Order 13407 and has established a program office to implement. Beyond that the current Emergency Alert System signal is an audio message only which pre empts all programming so that viewers who were watching color images of the trade center on Sept 11 would have been able to see only a screen with a generic text message along with a presidential voice over if an emergency message had been activated
