Retired AT&T Technician Mark Klein Speaks Out
Monday, 12 November 2007
On November 8, 2007 Mark Klein, who uncovered a secret surveillance room run by the NSA while employed as a San Francisco-based technician for AT&T, was in Washington to lobby against granting retroactive legal immunity to telecommunications companies.

In an interview, Klein explained why he traveled all the way from San Francisco to lobby Senators about the issue: if the immunity provision passes, Americans may never know how extensive the surveillance program was -- or how deeply their privacy may have been invaded. 

"The president has not presented this truthfully," said Klein, a 62-year old retiree. "He said it was about a few people making calls to the Mideast. But I know this physical equipment. It copies everything. There's no selection of anything, at all -- the splitter copies entire data streams from the internet, phone conversations, e-mail, web-browsing. Everything." 

What Klein unearthed points to a nearly unbounded surveillance program. Its very location in San Francisco suggests that the program was "massively domestic" in its focus, he said. "If they really meant what they say about only wanting international stuff, you wouldn't want it in San Francisco or Atlanta. You'd want to be closer to the border where the lines come in from the ocean so you pick up international calls. You only do it in San Francisco if you want domestic stuff. The location of this stuff contradicts their story."

  That's what's at stake in the telecom immunity provision, Klein believes. If the surveillance-related lawsuits are invalidated by a provision in the intelligence-committee-passed FISA bill, then the extent of the program -- at least between 2001 and 2006 -- will remain the exclusive purview of the Bush administration, the communications firms and the handful of Senators selected to review legal justifications for the program. "These are not babes in woods. They knew what they were doing," Klein said. "The violation of the Constitution is where they split off -- where the splitter splits off full copies of a datastream, and connects to other companies' internet stuff, like Sprint or GlobalCrossing. They don’t want people to understand that. They want to portray it like the president does, that it's a handful of international phone calls. That's the soundbite, and that’s not true. It affects millions of people domestically." 

"Since the San Francisco 'secret room' is numbered 3, the implication is that there are at least several more in other cities (Seattle, San Jose, Los Angeles and San Diego are some of the rumored locations), which likely are spread across the U.S.," Klein wrote. 

Klein has been public with his insider account for nearly two years, with precious little publicity to show for it, thanks to the relative paucity of national media in San Francisco. Coming to Washington might have changed that: his day was packed with press calls and face time with at least a half-dozen Congressional staffers, mostly from Democratic Senators Joe Biden, Sheldon Whitehouse and Barbara Boxer. Press attention and one-on-ones in the corridors of power might be nice, he said, but it's not enough. "I'm not impressed by people with speeches pretending to be on your side," he said. "I want to see votes. In our favor."

Statement: Mark Klein, April 6, 2006

My background:

For 22 and 1/2 years I worked as an AT&T technician, first in New York and then in California.

What I observed first-hand:
In 2002, when I was working in an AT&T office in San Francisco, the site manager told me to expect a visit from a National Security Agency agent, who was to interview a management-level technician for a special job. The agent came, and by chance I met him and directed him to the appropriate people.

In January 2003, I, along with others, toured the AT&T central office on Folsom Street in San Francisco -- actually three floors of an SBC building. There I saw a new room being built adjacent to the 4ESS switch room where the public's phone calls are routed. I learned that the person whom the NSA interviewed for the secret job was the person working to install equipment in this room. The regular technician work force was not allowed in the room. 

In October 2003, the company transferred me to the San Francisco building to oversee the Worldnet Internet room, which included large routers, racks of modems for customers' dial-in services, and other equipment. I was responsible for troubleshooting problems on the fiber optic circuits and installing new circuits.

While doing my job, I learned that fiber optic cables from the secret room were tapping into the Worldnet circuits by splitting off a portion of the light signal. I saw this in a design document available to me, entitled "Study Group 3, LGX/Splitter Wiring, San Francisco" dated Dec. 10, 2002. I also saw design documents dated Jan. 13, 2004 and Jan. 24, 2003, which instructed technicians on connecting some of the already in-service circuits to the "splitter" cabinet, which diverts some of the light signal to the secret room.  

The circuits listed were the Peering Links, which connect Worldnet with other networks and hence the whole country, as well as the rest of the world.

One of the documents listed the equipment installed in the secret room, and this list included a Narus STA 6400, which is a "Semantic Traffic Analyzer". The Narus STA technology is known to be used particularly by government intelligence agencies because of its ability to sift through large amounts of data looking for preprogrammed targets. The company's advertising boasts that its technology "captures comprehensive customer usage data ... and transforms it into actionable information.... (It) provides complete visibility for all internet applications." 

My job required me to connect new circuits to the "splitter" cabinet and get them up and running. While working on a particularly difficult one with a technician back East, I learned that other such "splitter" cabinets were being installed in other cities, including Seattle, San Jose, Los Angeles and San Diego.
