Is the relevence of DOCSIS of any form purely on the final leg of the network anyway - ie between the UBR & the subscribers modem?

There is also the core of the network which I assume with be ethernet based and then peering with other providers.

If VM don't invest in those areas as well then all we will see is that the technology between the UBR and the subscriber will improve but the rest of the network will not without further investment.

Now I knwo the UBR isn't actually in the green box - so I assume each green box aggregates back to a single UBR port somewhere? Or does each piece of Coax to a home connect to a seperate UBR port?

Are the UBRs local to the area they serve or all held in a few central locations?

Does the roll out of DOCSIS 3 require new equipment in the local green boxes too or just at the UBR?

Does DOCISIS 3 employ any more advanced security to try to eradicate those stealing bandwidth?
