No, I cant.
This was always going to be the problem on the 'Direct in ground' cables, especially the rural routes. It's been a long while since I've seen the pricing structure, but our contractors used to charge around £40 per metre for digging in tarmac, I think this drops to £25 in soft (Grass etc). Whatever it is, it adds up to a lot of cash.
As a business model, I don't know where this type of scenario stands with regard to recouperating ones losses over a period of time. Captain Picard will be receiving an OBE, by the time Ewhurst allow BT to cream some profit.
Of course, these are just my owh thoughts, I don't know if there is indeed some fantastic 'Duct-laying digging machine' waiting to be trialled somewhere ??
