Um, POTS phone lines *are* strictly analog, from the modem to the CO.
I wouldn't want to bet that 56K is impossible even with POTS copper at
each end, with suitably smart probing of the signal path and adaption
to its observed characteristics. (Which is not to say that modern 56K
modems can do that.)
As I understand it, that's not the way 56K works--you can hook two
56K modems back-to-back on your workbench and they won't do 56K. As
I understand it, on end has to interface to a digital phone line.
One A/D conversion allowed. Hence, the line from you to your ISP is
not "striclty" analog.
