Changing ADSL settings in Cisco 877 from PPPoA to PPPoE

Hello experts,

We have a Cisco 877. It was connected to an ADSL line with the following settings:

interface ATM0
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto
!
interface ATM0.1 point-to-point
 pvc 8/35
  encapsulation aal5mux ppp dialer
  dialer pool-member 1
 !
!
interface Dialer0
 ip address negotiated
 ip nat outside
 no ip virtual-reassembly
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp authentication chap pap callin
 ppp chap hostname ######
 ppp chap password 0 #######
 ppp pap sent-username ####### password 0 #########

Now we will connect a new ADSL line to the Cisco 877 with the following new settings:

Encapsulation: PPPoE
VPI: 0
VCI: 33
Username: Newuser
Password: newpass
MTU Size: 1492

Would you please help writing the configuration chaning commands?
