A question on another forum made me wonder about this, and the exact technology used.
I didn't see any details on Kitz main site, so maybe one of the BT experts can explain?
From what little I know, new (powered) cabinets are installed "fairly close" to the existing phone cabinets, presumably linked somehow (but how?).
Presumably these terminate the fibre from the exchange and then provide a local "broadband" type of signal.
But how are they then tied in to the phone EXACTLY and delivered to your house?
For example is it a separate cable (seems unlikely) or some sort of multiplexing (presumably) - proprietary or like ADSL alongside voice?
And does the voice then use the fibre, or does the old copper line to the exchange remain?
Whichever is used, how is the cable to your house tied in to both services?
And what happens when you decide to give up on the system and revert to a "standard" phone line and enable ADSL?
A good explanation would definitely warrant a "sticky".
