Both the cable and PTT have wiring in the buildings, but I suspect it is all CAT5 or the European equivalent in each apartment. Most of these flats have not been renovated in 30 to 50 years and that is usually when the flat is renovated that wiring would get upgraded. The cable company will often insist on rewiring the flat's own wiring if it has never provided service before.

However, the cable company just upgraded its network and is now offering up to 500. I assume the cable company is using coax and may be that gives them an edge when combined with VDSL to get up to 500 megs. ________________________________ From: Phil Lavin <phil.la...@cloudcall.com> Sent: Tuesday, October 15, 2019 7:48 PM To: Rod Beck <rod.b...@unitedcablecompany.com>; Nanog@nanog.org <Nanog@nanog.org> Subject: RE: VDSL > 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 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...
