Router and DSL modem relationship

Hello, everyone:
I am using a DSL modem (Seamens SpeedStream) and a router (Belkin).
The setup works OK from day one, but it just occured to me that I do
not fully understand a relationship
between the two.
Without a router, DSL modem would have an IP address of 192.168.2.1
(for instance) for LAN and
something like 70.52.xxx.xxx for WAN (Internet). I would be able to
access modem settings by entering
192.168.2.1 into a browser address box.
Now, with router attached, I can access router settings by entering the
same or similar IP address.
Now I have three hosts on my home network, namely:
router - 192.168.0.1 for LAN and 70.52.xxx.xxx for WAN (kinda converts
one address into another
and splits it with DHCP)
desktop - 192.168.0.2
laptop - 192.168.0.3
Fair enough. But what happened to DSL modem in this scheme. Does it
have any IP address?
How does it communicate with a router? Or is it simply done on
different OSI layer, such as MAC address?
And is there any way to access DSL modem's settings the way I can
access router's settings?
I would appreciate if someone takes time and clarifies this to me or
provides me with appropriate links.
Thank you.

Check your router (Belkin) wan ip address, it will show you what your
DSL (SpeedStream) ip range is and from that you can find out what the
DSL ip address is... You said that the wan ip on the Belkin is
something like 70.52.xxx.xxx for WAN so you know the ip address that
the DSL is giving you...

The DSL modem communicates as a network bridge. It still has the same
private IP address, but you can only reach that address if you are on
the same subnet (which you're not).
