So far, most of my queries from clients have been for x2. That coupled with the fact that the cheapest entry point for antthing that will do k56 and v.34bis (and optionally native ISDN) from Ascend is ~$7.5k. I'm attempting to kludge together something that will let me transition from my rack of individual analog lines & modems to digital stuff without killing the (non-existant) capital budget :^<. I have been wondering about the various ISA bus cards that have been showwing up lately such as the Cardinal or the Ascend Netwarp. My understanding of these is that some part of the protocol and/or call handling is done in the driver, but I'm not sure how it's split between hardware & software.
