You should ask your service provider, if you should be using pppoe or pppoa.

I have a similar setup with dialer interfaces, and it works perfect with dialer interfaces and PPPOE. Provider is SBC>

hi,

Don't use PPPoA, it did not work, use PPPoE only

create dialer interface,

interface Dialer1

ip address negotiated

ip mtu 1452

encapsulation ppp

no ip route-cache cef

dialer pool 1

ppp pap sent-username xxxx password xxx

then remember,

add this one under your atm 0/0/0.1 point-to-point

pppoe-client dial-pool-number 1

good luck
