And forgive me for being overly technical, but it's really a
combination router/gateway, not a router/modem. The term "modem" is
short for "MOdulator-DEModulator." Technically, it's a device that
converts the analog signal on the telephone line to the digital signal
needed by a computer, and vice-versa. Technically, any device that
doesn't do that analog to digital conversion is not a modem (Here's my
standard post on modems:

Are you telling me that a DSL 'device' doesn't modulate the digital
signal over an analogue line into several different frequency bins and
demodulate what it receives back into digital? If you are saying that
then just how does it work?


What I wrote is my understanding of how it works. If you want more
details, sorry, I'm the wrong person to ask and I can't provide them.



It's still the sane old analogue telephone line until it gets a
modulator and demodulator at each end to make it a digital subscriber
line.
