I just have a script that runs from cron like thus:

* 6-17 * * 1-5  root    /root/bin/ChkModem
0 18   * * 1-5  root    killall pppd

ChkModem is basically a script that pings the other end of the link, and
if it fails, and it hasn't redialed too often recently, it redials.
No need to put something in rc.local that knows about time, because the
cron script takes care of that.
And any time the link drops out during the day, it will redial within the
minute.

Just call it from cron. No need to have it anywhere else.
