PPP: deflink: Carrier lost & open -> lcp ?

[Atle Kristensen <afk@tiscali.no>]

I wonder what these two lines means?
Sep 20 17:30:24 farmor ppp[6321]: tun0: Phase: deflink: Carrier lost 
Sep 20 17:30:24 farmor ppp[6321]: tun0: Phase: deflink: open -> lcp 

Is that related to modem-hardware error?
(my modem/line dies and/or are unstable sometimes.
This dies and all pings are unresponded for a while, until the modem "wakes up" and 
all these pings are catched up and replied.

OpenBSD 3.1 i386. (RELEASE with ssh patched)(dmesg at bottom)
