Unfortunately most of Dobcross is fed direct from the exchange as this is located on Dobcross New Rd, so not far away. This means that Fibre from the cabinet is not available as these properties are not fed from a cabinet. Also cabinet 8, which is at the bottom of Wall Hill Road, is not planned to be enabled for FTTC, again most likely reason being people fed from this cabinet are relatively close the exchange anyway. ADSL2+ is planned in Jan 2012 as an alternative to FTTC for those who can't get it.
Some higher parts of Dobcross are however fed from a cabinet in Diggle/Delph. PM me your postcode if you need me to check your availability.
