Hi,
you probably need to set ppp over ATM and not ppp over Ethernet:

you should try the following (please be sure that pvc numbers are exact, your ISP should tell you):

interface ATM0
 no ip address
 no atm ilmi-keepalive
 pvc 0/35
  encapsulation aal5mux ppp dialer
  dialer pool-member 1

interface Dialer1
 ip address negotiated
 ip nat outside
 encapsulation ppp
 dialer pool 1
 ppp authentication pap chap callin
 ppp chap hostname XXXXXXXXXXXXXXXX
 ppp chap password 0 3920
 ppp pap sent-username XXXXXXXXXXXXXXXXXX password 0 3920

that's all you should need, (i can't see what reference has the "ip access-group 101 out" in your config)

hope this helps

On my modem, after providing the username and password ( given by ISP) the release auto configuratio It shows pvc value as 0.200
i forgot to remove that access group.

Hi,
i've never seen pvc 0/200, i believe you're using the wrong number.
You should check with your isp (they MUST tell you).
You may want to try pvc 8/35
