Ha! I think I have it. In the TVA50 console PORT/TRUNK service the Service Group also specifies Day, Night, Lunch, and Break modes. I changed the "Delayed Answer Time" for Day mode to 30. That seems to be added onto the 15sec specified in the TA-824 start time mentioned in my previous post.

Whew, that's a relief. I'll be sure to document this in our wiki . . . --Ray
