    What infrastructure do NTL and Chorus actually have? Is it fiber to the kerb, or is it mostly coax?

    Lets call it fibre to the estate in this country , FTTK (aka FTTC in the US) is typically fibre and then co-ax for c.50 houses. NTL and Chorus often only have fibre for maybe 200 houses or 300 houses.

    This arangement is called HFC, hybrid fibre co-ax In telco land the equivalent is sometimes called FTTN (fibre to the node) where fibre is pushed nearer the user to get higher BB speeds from ADSL2 and VDSL. Telcos use copper pairs not co ax . Eircom trialled one with VDSL in S County Dublin starting this time last year.

    In Korea where they often live in large apartment blocks its called FTTB (building).

    There is no single way to do it as the FTT(whatever) proposition is all about reusing existing copper as much as possible but NTL and Chorus have more fibre nearer their customers , normally, than eircom do .

    FTTH is a mere mirage in this country given the overweening uselessness of our building regulations and duct provisioning and also the low quality of our local govt planners , normally 3rd class geography degee things .

    if they have iber to the estate (FTTE I suppose) they could bring it on to the individual block if the demand were there, no?

    In terms of the way the copper is laid out, is it typically a single shared coax for the 200 0r 300 houses, or is it segregated into smaller pieces?

    Demand? Sure aren't people spending half a mil on houses that don't even have phone lines? It's hard to see much evidence of demand driven rollouts here. Most fibre rollouts world wide are provider driven, because they can derive greater revenue from increased and new services, rather than demand driven.

    If NTL can develop a reliable VoIP service, they could afford to spend €500 (2 years "line rental") per house to roll out fibre to the home, and set themselves up for a major cash cow in years to come.
