Hello, Below.....
This is also my understanding. I thought I saw some work being done on an enhanced DXI specification, (the interface between the router and the ATM DSU), but I think that, for the most part, not much work is being done with ATM DSU solutions today. ATM DSUs were largely developed as a quick-to-market solution for adding ATM functionality to routers, without the need for new router boards. Their time has passed.

I don't think that HSSI was designed as a point solution until ATM came along. Couching your answers in the context of an ATM solution is presumption, or so it appears to me.
Agreed. On a side note, the HSSI card does not terminate in a V.35, but rather in a HSSI physical connection, similar to a SCSI physical termination. I wouldn't ponder the intent of the designers of the HSSI card. However, I would hazard that a good percentage (3-15) of the HSSI cards are used for access points to iMUXes.... -alan
