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?

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.

I don't know if I am right but I always suspect that when the telephone
went digital in the 1980's, the differnce in the transmission of the
digital conversation and data converged into the same basic system.

Went digital? POTS never went digital. Are you thinking of VoIP?

I assumed this because of the a telephone number is the same number of
digits as a URL

Note that what follows is not a URL, but an example of an IPv4 address.

192.168.01.01
919-333-3636

Is this assumption correct?

That's an interesting theory. Alas, it's completely wrong. :-)
