Thanks, I didn't mean this hypothetical as a way of skirting the rule—I just didn't know if the FCC was concerned about how EAS-like broadcasts are processed by machines or how they're processed both by machines and by humans. I remember that the old EBS tone could automatically trigger some stations (like ours) to switch over to rebroadcasting a transmission from another station. I believe that the EAS signal does the same. At least in the EAS case, I didn't know whether the FCC was specifically hoping to catch humans' attention with the tones, or just to use them as a signal to transmission equipment to rapidly change the content it was broadcasting over to emergency announcement content, even without human intervention. Several of the replies here, including yours, suggest that the FCC explicitly means for it to serve both purposes.
