[EAS] Resolved- Nationwide AT&T Mobility 9-1-1 outage

[Sean Donelan]

Again, why use Civil Danger Warning (CDW) which is the most extreme of the 
generic codes (most severe CDW, in the middle CEM and lowest LAE)?

NOAA National Weather Service describes Civil Danger Warning as

   A warning of an event that presents a danger to a significant civilian
   population. The CDW, which usually warns of a specific hazard and gives
   specific protective action, has a higher priority than the Local Area
   Emergency (LAE).  Examples include contaminated water supply and
   imminent or imminent or in-progress military or terrorist attack.
   Public protective actions could include evacuation, shelter in place,
   or other actions (such as boiling contaminated water or seeking medical
   treatment).

Is a 9-1-1 outage really as severe as an imminent military or terrorist 
attack using a Civil Danger Warning (CDW)?

CEM was part of the original SAME/EAS code list, and implemented by all 
weather radios, all EAS equipment, all cable set-top boxes, etc.  If the 
claim is we couldn't use TOE, then CEM is the most widely implemented 
alternative.  CEM is a little later in the alphabetical drop-down list.

Other than CDW appears earlier in the alphabetical list, what is the 
reason for using CDW instead of CEM?

The longer term change would be to update WEA and IPAWS to include the TOE 
code since the FCC made the change to allow telephone numbers and URLs.
