Does the circuit sync in first place? Check "show dsl interface".

Yes, it does.

hi,
please look in to the dialer config,
interface Dialer1
ip address negotiated
ip mtu 1452
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer pool 2
dialer-group 2
no cdp enable
ppp authentication pap callin
ppp pap sent-username XXXxx password xxxxxx
dont enable chap use only Pap as mentioned above

doesn't work.

You show not give one-line answers and bring more info instead.
To begin with, send revised config, show dsl interface, debug ppp negotiation.

Try adding the following
!
vpdn-group global
request-dialin
protocol pppoe
!
... and be aware of your MTU settings, I am not sure of your ISP but usually is as follows.
!
interface Dialer0
mtu 1492
!
and the physical eth will be...
!
interface Ethernet0
ip tcp adjust-mss 1452
!
