One other point about the AIPs relative to the HSSI/DSU ; you may not be interested in this feature , but the AIPs implement traffic shaping- ie You can set Peak and Average rates and burst size; you could use this to subrate your traffic -should you be in a situation where this is desirable.
That is my understanding. I think that this is part of a some more general observations: o The AIP card is a more intelligent card and can perform more functions today and is much more likely to perform more functions in the future. o I suspect that few, if any, new ATM features will be added to the HSSI card. Again, your router vendor should be telling you all of this.
I havent looked around to check out any new ADSU type products since mid 95, but it used to be that you could not do this with an ADSU.
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. -tjs
