I discovered that the Budapest cable company was using VDLS to provide services up to 500 megs into the buildings where my flats are located. VDSL is a pretty old standard. I recollect people talking about it back in 1998.
Is it being heavily deployed in Last Mile networks state side?
DSL on the whole seems pretty unpopular in the USA. VDSL itself is a fairly old standard but it's been enhanced over the years to provide bandwidths up to 300mbit on a single twisted copper pair, albeit over relatively short distances. DSL (these days, specifically VDSL2) is extremely popular and widely used within the UK because almost every home has a single twisted pair going into it for a POTS phone line. It made sense to run services over this than to re-cable 25 million homes. A (very) slow FTTH rollout is under way but what seems to be getting more traction is a rollout of G.Fast which currently boasts speeds of up to 500mbit over short distances (< 100m), still on a single twisted copper pair. This may be what you're getting as VDSL2 won't push to 500mbit over any sensible distance. I can only speculate on why they decided to use DSL in your building - if it has legacy POTS infrastructure to each apartment, it would make some sense. If not, who knows...
