It's worse then that. It takes into account that all multi tenant buildings will be FTTB If they are not if they cut the main cable down the street at the splice and start inserting road side boxes. What of all the other services running inside building's that are shearing the building block cabling. We are talking VDSL2+ old SDSL right down to old digital pabx's firelines and god knows what. What an ongoing nightmare this whole thing is going to be to maintain and deal with daily faults.
Matt.

<pre>interesting my arse! George, they're the vendor who proposed the standard!
you've seen Simon Hacketts piece on whirlpool where he makes it explicit vectoring cannot work in out competitive environment? it demands re-centralization of the copper because it uses the same RF space as ADSL to do slightly different, but incompatible, modelling of noise.
Its one or the other: entire D/SLAM replacement required. the whole bundle does one, or the other.

Interestingly, they are using equipment from Alcatel-Lucent.<br>
