That logfile indicates that PPP isn't able to establish a session within
the timeout.  NM times PPP out after 20 seconds, which is a pretty long
time to give PPP.  I've actually never seen PPP take more than about 5
or 10 seconds to connect, even in marginal situations on any of my 25 or
so devices.
