try adding

  accept lqr
  enable lqr
  enable echo
  set echoperiod 15

to either the default or provider-specific section of ppp.conf to enable
ppp to check the link is alive.  After so many failed echo or lqr packets
it'll drop the connection and redial.

The above is copied&pasted from my PPPoE config which definitely does
detect the remote end going away and redialing.
