Yes, I am very familiar with them:
As that page explains, they are only pseudo-DSUs though. I much much
prefer a true bit-transparent DSU:
I have also designed and built an SDSL to EIA-530 DSU of my very own:
On the latter I have the hardware (the page above has a photo of the
board), but the operational software (or firmware if you will) remains
to be finished.

Only in the very limited geographic footpring of what used to be DSL.net
- they are the last remaining semi-major operator of CM DSLAMs:
My big goal is to make my own DSU which I have just mentioned function
as a Layer 2 converter (FRF.8 and friends) from Nokia SDSL/ATM served by
Covad to HDLC.

I don't think anyone have *ever* used V.35 & friends with ADSL -
probably because those who would want V.35 (i.e., people like me) would
find ADSL morally offensive. :-)
