Voice on FTTC

When broadband is switched to FTTC does the voice component switch too? I.e. does the voice part of the line travel from the cabinet back to the exchange via fibre optic cables?

No, it remains on your original copper pair.

At what point in the route to the exchange does the pair which leaves my house split into two? Is it split before the two cabs, then one pair fed into the old cab, one into the new?

In simple terms:

The pair from your house goes to the old cabinet. It is then connected to a tie pair which goes to the new FTTC cabinet and when it reaches there, the VDSL and voice are split. The VDSL is dealt with at that point and fed back to the exchange over fibre, whilst the voice signal is routed back to the old cabinet on another tie pair where it is connected to the original pair from the exchange.

Great, thanks for the info.

Also, in many cases the fibre goes to a different exchange. It still counts as your exchange being enabled though.

More info. Basically they've just installed a DSLAM nearer to you, as that's what happens in the exchange on ADSL2+ - it all goes to the DSLAM/MSAN and gets split by it.
