FTTC is *provided* by BT Openreach. They do the physical infrastructure
from the exchange to your house. Any provider, including BT Broadband,
can use FTTC (where available) to provide a broadband service for you.

Tangent alert. The local DSLAM cabinet was installed outside our house
a year ago, and since then, there is often an Openreach van there, with
a little man doing things in the cabinet. Daft question perhaps, but
presumably an engineer is not required to make a connection within the
cabinet every time someone switches to FTTC broadband?

It depends on what's in the cab.

On the old systems they have to jumper between the voice and the dsl
racks if the user wasn't already on dsl.

On the newer stuff there is a software switch that changes between the
adsl and the vdsl protocols so no visit is needed to move from adsl to vdsl.

On the very new stuff the voice and the dsl are in the same rack and
there is no visits to enable dsl in any flavour.
