Huh? Seems to me we have much more than that. NSA may be able to tap optical cables without AT&T knowing (or with them looking the other way), but in general that's not the way they're going to eavesdrop. The only way they can cost-effectively get the access they need is in the electronic domain, and there's little doubt in my mind that they merely asked for certain traffic to be dropped-and-continued onto NSA gathering points. Why? For one, there's just no way they'd be able to deploy a duplicate optical network that backhauls all of the relevant traffic to NSA facilities. They can't even secretively grab individual DS0s and backhaul them without cooperation. Optical span + EDFA noise budgets will first of all prohibit this (ie, it ain't good if your tap brings down an AT&T cross-country OC-192: 3 dB matters to optical amplifiers). Second, to have ready access to any DS0 in the country is impossible without help. Consider even a single 128 wavelength optical cable carrying OC-192 on each lambda: they'll need a tap, a 128 (optically amplified) DEMUX, an OC-192 SONET terminal for EACH wavelength and some way to grab individual DS0s (or maybe they just take the DS1). And THEN they have to backhaul that somehow. And that's just one cable. It's just physically impossible for them to grab everything and backhaul, of that I am convinced. My assumption is that EFF folks in the know already know this. They might have even just picked AT&T nearly randomly...any of the big long haul carriers will have had to collude, and probably didn't even seriously consider not colluding. -TD

EFF has sued AT&T over its alleged participation in the NSA's surveillance scheme: http://news.com.com/2100-1028_3-6033501.html
Complaint: http://www.eff.org/legal/cases/att/att-complaint.pdf
BTW I think the ACLU's map (below) is intended to be more fanciful than based on any confirmed participation by U.S. telecom or Internet companies.
The closest we've come to actual confirmation was a paragraph buried in the middle of a Los Angeles Times article last month about AT&T, mirrored here and cited in the EFF suit: http://www.libertypost.org/cgi-bin/readart.cgi?ArtNum=122448
Am I missing something?

Declan,
Politechicals may be interested in a new ACLU white paper and interactive map detailing what is known and suspected about how the NSA's illegal spying on Americans occurs and where the interceptions are likely taking place.. The white paper is entitled "Eavesdropping 101: What Can the NSA Do?" It looks at the probable connections that the NSA has made to the U.S. civilian communications infrastructure. The map shows how the NSA's "surveillance octopus" likely entangles the country. We believe it is the first effort to visually illustrate what is happening.
You can find both the white paper and the map at <http://www.aclu.org/safefree/nsaspying/23989res20060131.html>http://www.aclu .org/safefree/nsaspying/23989res20060131.html>http://www.aclu.org/safefree/ns aspying/23989res20060131.html.
