You don't have to be POTS to be called a "phone line". ISDN is also a phone line system.
Also, the phone frequency range is more like 400-3400Hz (ever noticed the lack of bass from the phone?), making bandwidth more like 3000 Hz with 8 bit per sample encoding. And in fact, that comes close to actual data rates achievable with a "56k" modem.
I really hope we get a 56k expert in this thread at some point. You and I are obviously not experts. :(
