    I rang NTL today asking about this as i'm moving into an apartment in Rathfarnham at weekend. They said 2/3 months

    Did BT really say that as you're renting or 'cos you're a student?
    I'll be renting too.
    I rang up BT again and told them I got a job and quit college. They had to take my word. I have now got BB ordered :)

    BTW in most cases they don't need to replace the cable with two way, that is just a myth, any 550MHz quality cable is well capable of two way. What they need to do is install a CMTS in your local node (a CMTS is like a DSLAM to the cable companies) and ensure there is sufficient fiber running to the node. They may also need to reorganise the local network somewhat and remove old repeater devices.

    If I recall, and that's possibly a myth too, they started using some new technology at the start of this rollout that made it easier/cheaper to use the existing cable infrastructure.

    I'd say now their problem is to get fibre to the headends.

    I have no inside info on NTL's setup, I just have general knowledge on how cable works.

    I'd guess that back in 2000 much of NTL's network could have been old crappy analogue Amplifiers with little fibre. Since they have moved to Digital TV throughout Dublin they would have had to replace much of these old amplifiers with fibre to your local neighbourhood hub.

    As time goes by and NTL want to rollout new services such as higher BB speeds, more customers using BB, higher maximum frequency over the cable (allows for a lot more channels, higher BB speeds, etc.), BoB and VoD services, they will need to reorganise and update the network as they go. Creating more local hubs, with the hubs feeding less customers and closer to their customers. These hubs would then be feed by fibre. This is what a modern Fibre-coax network looks like.

    BTW if anyone is interested in how Cable TV works there are interesting articles here:

    Thanks BK, I've been interested in this for a while, could never find any decent info on how cable BB worked.
