According to the specs, it's supposed to be sending a digital signal through the copper, at a different frequency than the analog voice component.No, it's not a lie, per say. A DSL modem demodulates an analog signal from the wire into digital information. It also takes digital information and modulates it into an analog signal and put onto the wire. This is roughly the same as how a dialup modem works.
It also performs routing/bridging at a higher layer on the OSI chart.
Regardless, the signal normally flows across the POTS line as an
analog signal.
It's supposed to be digital all the way from the dslam on out. The "modem" is really just a bridge, between the DSL digital signal and the ethernet digital signal.
Or, this was how it was explained to me by one of the electrical engineers I've spoken with.
