If they needed to pull a cable from the green cabinet, would that not involve digging up the street? Or can they pull it from next door over to mine?
You should see a small cover about 3 to 4 inches square on the pavement between two perperties, it should look like the water stop valve cover, VM will have run ducting along the street placing a cover like this on the boundery between every two houses. They will pull the cable from the nearest green box to this cover and then all they have to do is dig a narrow trench about six inches wide and it should be a foot or so deep, they'll dig this from the small cove down your garden to the wall where they will install a grey box.
