Even a failed result can be a successful test
如果你住在美国，很可能是因为你只在夜间2020欧洲杯夺冠热门由中间被唤醒睡着了与电视刺耳的高音音调从你的电视机，随后深沉的男中音的声音，让你知道，有没有积极的核攻击或警告，哪些是你所经历只是一个测试。
该Emergency Alert System(EAS) was designed as a tiered distribution mechanism, very much like a pyramid, with the President of the United States positioned at the pinnacle. As you move down the tiers of the pyramid, you become more regionalized and localized in the coverage area that is served. Using this logic, any participating station in the chain can initiate an emergency alert message, and by default, the information will trickle down to the lower tiers as stations monitor the tier above them.
小时候，该系统被称为EBS，其主张紧急广播系统。It was later updated and renamed to the Emergency Alert System, but the mechanism is still tested on a weekly and monthly basis. The weekly tests are the local stations that serve their direct broadcast area, and the monthly tests are focused on distributing messages received from an Entry Point Station, in an effort to test the distribution mechanism.
在奇数个月，每月测试上午8:30和当地日落之间进行，日落和上午8:30之间的晚上测试上甚至几个月运行。虽然美国总统的能力存在作为顶级切入点紧急警告消息，它从来没有被激活或使用。2020欧洲杯夺冠热门正因为如此，在2011年11月20日，美国联邦通信委员会（FCC）与联邦紧急事务管理署（FEMA）一起决定在下午2时运行该系统的实际“试活”美东时间。在此测试，而不是使用测试代码激活系统中，主席将在国家紧急情况下使用的实际现场码将被用来触发系统。
也许并不完美，但失败可能是强
虽然许多报道EAS的彻底失败，联邦通信委员会发出表示故障率接近18％的报告。当然不是完美的，但与社会媒体和很可能已经部署在个人基础上其他形式的通信耦合的，我相信它是安全的假设，世界将变得及时已经得到了。
与测试最大的问题，我看到的是显著技术的不一致与什么人耳闻目睹。有的站显示的文本消息，但没有音讯，没有提示音，肯定是有人谁是盲人的一个问题，而其他台播出了紧急消息的音频，但并没有显示这些信息的文本，留下一个人谁是聋哑人或重听完全不知道当时的情况的。
Making the news—one way or another
仿佛是为了确保社交媒体有一些东西去病毒和咆哮一下，许多用户的DirecTV看到了紧急警报系统的图形，但一些观众据报道，treated to Lady Gaga's recent Top 40 hit, "Paparazzi."你知道，有时候你不能让这些东西了，讽刺喜剧刚刚毫不费力本身写道。
It's no great surprise that human error contributed to many of the issues that were found, with some technical inconsistencies sprinkled in that are pretty much a given in today's ultra-modern digitized world.
But that is what tests are for. If a test never failed, you would almost have to think and ask yourself if the test was even valid? After all, everything has a breaking point, and even something as simple as a lightbulb will ultimately burn out one day. Without testing, you're going to find it when you least expect it—and likely need to rely on it.
Based on this, I don't consider the fiasco of five years ago to be a failure. It was literally the first time something had been tried from the presidential level, and hopefully we learned a good lesson. This Wednesday, on September 28, at precisely 2:20 p.m. EDT, another test message will be inserted at the Primary Entry Point, the President of United States, and a "live code" will be used. Hopefully, things will run a little smoother this time, but citizens should know that they may not see or hear text that indicates a test is in progress. According to theFCC EAS手册AM和FM电台（PDF），你听到实际的消息可能是这样的：
这是一个紧急行动通知。所有的广播电台和有线电视系统应将这种紧急行动通知消息。该站已在白宫的要求，参加紧急警报系统中断了正常节目。
During this emergency, most stations will remain on the air providing news and information to the public in assigned areas. This is (station call name). We will continue to serve the (EAS local area name) area. If you are not in this local area, you should tune to stations providing news and information for your local area. You are listening to the Emergency Alert System serving the (EAS local area name) area.
不要用你的电话。电话线路应保持畅通，以备不时之需。
Can citizens take action?
如若EAS再次失败，目前还不清楚公民应该做的报告。有一两件事不能做的是拨打911和占用应急线。事实上，调用本地的行政线在派出所也将是那些谁没有权力来解决或纠正问题的时间和精力的浪费。
