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.
