To be fair, the CO I described[0] is a local switching center. The Nashville “CO” was the area long lines/tandem/long distance site. Now, I’m not defending the lack of a backup plan, but tandems tend to be far larger than a typical local/class 5 CO. 0 - which like the Nashville long lines building also happens to be a pre-divestiture AT&T site, although at the time it was owned by BellSouth. It is also in Tennessee, although in Memphis, not Nashville.
