Well that depends. They are just 'regular' ADSL tails but handed off  
into a managed MPLS cloud. It's hugely expensive and unless you are  
connecting round the world not usually the most cost effective  
solution to make a private network. We make these for customers using  
DSL based closed user groups, which we can link in to MPLS once it  
comes out of the L2TP tunnel.

Must remove the cynical hat at some point soon!
