What would be the best way to find out?
Call them, if it's available in their system then you should be able to order it, but I doubt it though.
A couple of wholesale ISPs use it here, but they also sell MLPPP capable routers along with it. We now have 25/10 VDSL2 speeds for about $50/month so it's not worth paying for two or three 6Mbps loops anymore.
