I did this with a Cisco 827 a few years ago.  This router has an rj11 to 
accept the phone line, and ethernet to plug the lan into.  I had 
66.58.59.24/29.  I no longer have this block.  I initially thought I had 
to use .25 as my gateway, that turned out to not be true.

Here are the key pieces.  

!
!
 interface Ethernet0
 ip address 66.58.59.26 255.255.255.248
 no ip directed-broadcast
!
interface ATM0
 no ip address
 no ip directed-broadcast
 no atm ilmi-keepalive

interface ATM0.1 point-to-point

 no ip directed-broadcast
 pvc 0/35

ip route 0.0.0.0 0.0.0.0 ATM0.1
