Well, just to confuse things... The telcos are starting to bury CO's. The typical small to medium size CO is so compact that they can fit into a 10 X 20 building. To reduce taxes, eliminate zoning problems and reduce real estate costs, the telcos have found that a CO can fit into an underground module in the residential or industrial area. All you see is some HVAC stuff under a grill and a steel door leading into the ground. No cables, nothing ... even the power is buried. The new CO and DACS facility for the Florida Supercomputing Center in Tallahassee is an example of this. Of course AT&T has several larger buried transmission facilities accross the country, built in the 60's as part of a hardened defense strategy. (One of them is right outside Medina, Ohio.) These were much larger ... several stories of 50x60 building or more ... all 25 feet underground with a blast door. All the original L carrier stuff was mounted on springs, too. However, now that transmission gear is much smaller, much of these facilities are unused space. You see, they have converted most of the old L carrier coax routes to digital now.
