mci/vzb sales folks as a whole can't explain it either, but we offer it...
I'd suspect if the original poster would have used a more legittimate
email address they might have recieved a directed note back from one of
the several ATT nanog-readers...

(note, of course there are always sales folks that CAN explain these
things, but in general they end up asking a tech person inside their
company... or we hope they do)
