I maybe wrong but I don't think you can get 20 Meg on that line type, are you sure the exchange has been upgraded to 21CN?
I think you need to talk to support.
Mine says WBMC, I did try the 20 meg service but because of my line length it became quite unstable and ended up down to 350k, now get about 1.9 Mbps but with your stats you'll get a good speed I suspect.
