Re: Re: AT&T Switch operational in basement of WTC

I have doubts that they were referring to a 5E. Optical muxes, and passive 
optical feeds just passing through, maybe. The node in this case is the old 
Teleport Communications Group main node that became ATT/Local Network Services 
when they were acquired. I posted about this here in NANOG two days ago. It is 
six levels down and amply fitted with backup battery plant to sustain long 
outages, and was conceivably insulated enough to resist the turmoil above for six 
hours of continued service. Some elements in this node also stayed up and running 
for a moderately extended period during the last WTC failure, eight years ago, 
during the bombing incident of 1993. -FAC
