ADSL is also shared. Only the copper pair between the subscriber and DSLAM
isn't shared. I was recently working on some ADSL systems. On them, 2
DS3s where shared among 448 subscribers, each configured for 3 MB down.
That works out to 2 * 45 Mb / 448, less ~15% ATM overhead or about
170Kb/s, if every subscriber were trying to download large files at the
same time.
