And I think the modern The site where we locate our dialup equipment (ACC-Old Slip) is old-school telco. All 48V, all battery backed-up if you take the DC feed. It's brand new, but it does not have a raised floor, just overhead channels for all the telco wiring... They thought we were crazy when we asked for AC, but when told how many amps a USR TCH draws, they happily brought more AC to us. We're backed up by a generator, but that's it. During the time it takes to crank it up, we're dead. Now at Telehouse NY, (our cabinet being right across from Genuity, btw) they tell us that all power is coming from an inverter, and there is enough battery power to keep the entire facility going until the generator comes online. They even invite you to come out and see them disconnect the utility co. power during their quarterly tests... This is primarily a "datacenter" with a much higher count of things that say "Cisco" on them than those that say "Lucent" or "AT&T". They also claim they have 3 days of diesel fuel available... So I guess the rule here is, put your 48V stuff at a telco colo, and put the big AC stuff at a modern datacenter...
