All the photos I see of the 2000's rear panel show only coaxial/rca jacks. All the photos I find of the 2400 have both coaxial and optical jacks (as do many other vs models). Frankly, I've never encountered a coaxial/optical combo jack and I don't find any in web searches.
Maybe this was some sort of mod? Although it doesn't seem likely to me that such a beast exists - given my scant understanding of the differences between the two formats (which is mostly limited to the physical).
Rereading your post - I seriously think there is just one type of coaxial/rca jack - with the traditional round pin that the analog phono plug uses. The cable you are used to using is the only one I am aware of. It's a 75 ohm cable with the yellow boot, most often used for video in the a/v world.
