Ppp won't expect carrier if it's not detected when ppp starts doing
LCP. This allows null-modem cables without the correct wiring to
work.
As I've said to a couple of these posts - enable debug logging and
you'll see the carrier status reported every second. You can also
``show modem'' to see what things look like.

Ppp should be a lot more reliable these days.
