First, generally need to tell the dialer what authentication method to use:

enable
conf t
int Dialer0
ppp authentication chap
CTRL+Z

Might also want to set "ip add auto" on the Dialer0 interface.

Then back at the top level of privileged-exec mode do a debug ppp and watch it run for a while, let us know of any errors.

May also want to do a 'show dsl operating-mode' and make sure the sync'd line state is what you expect it to be.

for some reason i dont get the command 'show dsl operating-mode' . but i have phoned the isp and they say the ling is up and that they can ping the router. i cant ping out of the router, or ping from our office(not the same one as the one that the router is in.the pvc settings are correct. i just cant see what is wrong with it any more.
