You might start hunting on the used market for Occam/Calix B6 equipment,
specifically the B6-252 ADSL2+ and POTS card and the 12 slot chassis.

You'll have to put in some supporting infrastructure, but they do work
well, and I know of at least two aftermarket repair places that will repair
them for a reasonable (for the telecom world) cost.
