Residences like that if they had not been designed with conduits and wiring troughs for digital, telecommunication, low voltage wiring are a nightmare to retrofit. AT&T personnel usually just staple cabling along the baseboards of walls. Many of these home owners won't accept such a solution. They want Uverse with 8 televisions and several computers, and keep their Public Switched Telephone Network telephones. (because they will keep working through a natural disaster) Yet except for the door bell, a few phone extensions, maybe an intercom or two, there is nothing there. Also the architect and home builder made no allowances for easily running cabling. They will also not accept visible cabling, jacks, other infrastructure. The "Company" only allows you four hours to pull all of this out of your ass, because their time and motion studies are flawed.
For icing on the cake, some have had their landscapers plant trees very close to utility poles and telecom terminals making access risky if not impossible.
I was in an attic of a showpiece house. The imbecile who designed the house put a water heater in the attic. When it goes bad the only way that it can be replaced is to use a crane to lift it through a hole that will have to be ripped in the roof.
