AT&T Long Lines Department
This station is an active AT&T network facility. AT&T Corporate Security has requested that the names and exact locations of such facilities not be published. Accordingly, it is identified on this web page only by its CLLI code, ARTNVACKT20.
Location: Arlington County, VA
Active: None
Canceled: KYO63, to Waldorf, MD
ARTNVACKT20 features a pair of horn reflector antennas which transmitted and received through openings in the tall parapet wall screening the rooftop. Also on the roof, though only visible from a distance, is a large white communications satellite dish.
The property is surrounded by a tall security fence, and all entrances are protected by closed-circuit TV surveillance. The building has an underground parking garage, and an outdoor parking area, all secured by a motorized gate. A structure adjacent to the gate (see photo below) appears to be an emergency exit from the garage.
An underground cable route links ARTNVACKT20 with the station having CLLI designation DSVLVADV, a large, hardened underground facility in Fairfax County, Virginia. The route originally consisted of coaxial cable (L-carrier), but has been converted to fiber optics. The four repeater huts which supported the coaxial-cable link still stand along Leesburg Pike (Rt. 7).
ARTNVACKT20 was an AUTOVON switching center as well as a toll switch in AT&T's commercial long-distance network. Located less than two miles from the Pentagon, it likely provided important defense communications services.
The facility remains active and probably still serves both government and commercial customers.
