EAS Tones - Specification Source ?

1 - Does anyone know the official source and governing body of the technical specifications of the tones or signaling used to trigger EAS systems?

2 - And where we can get a copy of such?

3 - Also, I assume such devices must be "type approved" by the FCC or FEMA or who ever the governing body or bodies are... right?

4 - Also, is there a technical advisory community or group of government and private professionals who periodically review all the technicalities of the EAS system, including signalling encoding and decoding spec's and who may trigger an actual event and what events require system alerts... and assign level of significance to alert candidates... etc

Thanks for any info.

PS - It occurred tome that the signaling that triggers EAS systems may, in come cases, a combination of analog and digital... digital info encoded as analog tones or phase shift or whatever... so how ever it is done... etc is the subject :-)

47 cfr Sections 11.31 through 11.35.

Go to ecfr.gov select Title 47 then select parts 0-19 then chapter 11 and you can find these sections.
