Comms facility?

"Small, non-descript facility where 80% of all communications from Asia enter the United States." Watch Nova documentary "The Spy Factory" here:

view chapter 4, about 75% through. I think this is the facility they are talking about. I don't live here. Just started looking around here after it was shown on the show.
