1. -  you have an ACL applied to you LAN interface which only allows packets in between 8:30 - 20:30

    -  the ACL also only allows your router to ping a LAN device if you source it from the LAN interface... if you source your ping from any other interface its going to be blocked.

    - (time range most probable, do a 'sh clock' to see what time the router thinks it is)

2. ISDN not firing up because there's no traffic going across it ...

     - Check your watch list... do those routes exist when the primary link is up?

     - Check you dialer list ... you are referencing the same ACL (180) which again only allows traffic accross during the time period. check the time

3. whats all this got to do with IP SLA?
