"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."
