Every Qwest DSL modem I've seen (7+ years) contains a router (dhcp, 
nat). Even models w/out a switch (multiple connections) provide dhcp/nat 
on the back end. I currently have an Actiontec M1000 (a fairly new 
model) with one lan connection, but it still does dhcp and nat.

These DSL modems can be configured to operate in bridged mode (defeating 
the dhcp/nat features), but that's not typical.

Cable modems, on the other hand, don't typically have router 
functionality. I haven't had much experience with cable modems lately, 
but all the ones I've seen (still?) have no router features. They simply 
give the public IP address to the device (computer or router) that's 
attached to them. Some newer models might have routers in them, but I 
wouldn't know.

Trent's situation is DSL, not cable. ;)
