It is located in the North Little Rock suburb of Sherwood, AR. The EXchange here was Temple. It is a large building which shares the space with an AT&T staging center. It has no AT&T signage at all, but that large pedestal on the left side of the building has an imposing “No Trespassing” sign on it, nothing else. As in so many Arkansas offices it is called by 2 or more names, in this case, Temple, 835 and Sherwood.
