  • This is true. I am retired AT&T technician and manager.I rerouted the backbone network elements through 21 to the NSA building next door. I remember questioning the engineering that routed backbone data/phone nodes through the SNFCCA21/ds0. The ds0 designation is incorrect as that is low speed. We rerouted ds3 and oc3 backbones to this c.o. as mis routes to here,when there was no engineering reason. Never could get a "terminating address" as we just dropped coax and fiber on connecting ports.
