I'm trying to set up a Timed Call Forward on an extension on my Tadiran IPX500. I've found the parameter "TIMED FWD" and it's defined as:

"Allows re-routing a call to another destination according to the time period defined system-wide. This feature is the same as Call Forward All, except that it operates at specifically designated hours."

I need to have the receptionist's calls forwarded to another extension during her break and it seems this is exactly the feature to accomplish that, but I cannot figure out how to set the "time period defined system-wide."

Can anyone help with this one?
