The ironic thing is many telephone companies ended up using ATM to serve ADSL. My childhood home in rural Alabama still only has one terrestrial internet option and that is a 6 megabit ADSL line from AT&T (originally Bellsouth) served out of a remote terminal that is fed by an ATM circuit from the Central Office. My brother lives in that house and is prepared any day to finally get a notice from AT&T that they're discontinuing it

These days I think all of AT&T's flavors of DSL, including their IPTV-supporting VDSL, is considered 'legacy', but for the longest time their "IP-DSL" was the future, and for 15+ years they've been trying to shed this ATM-based DSL

Yup, they did that here too. You had to set up all sorts of ATM parameters when you configured an ADSL router, VPI, VCI, and others. However I no longer have access to that information since I used alcohol to sterilise the affected parts of my mind.
