I've asked a Jepp rep. to explain the difference between the two altitudes. His reply was that the 3000' is where the profile/3 degree slope starts (constant angle) where as the 1100T is the lowest you can go if you choose to "dive and drive".
So the profile on the chart should show the DME/ optimum altitude from 3000'.

I don't doubt what you say which is my interpretation of the plate as well. But could you ask your Jeppy rep exactly where in their manuals is this explained. We could not find anything in the chart legends which explains the terminology used on this chart.
I think 1100 ft is also the height which is the lowest to use if your sole means of navigation is by reading road signs. It would certainly raise a few eyebrows
