CATV basically indicates its Cable TV . If threre is not any cable service in the area then it suggests that although the cabinets were installed , and possibly the underground duct work, the area may not have been physically cabled. This did happen in some areas when the money ran out.
This is exactly what happened on our estate when it was being built. NTL as it was known then pulled out because of lack of funds. We have the underground ducting in the street and to the house but no cabling.
The newer part of the estate was abandoned totally without any ducting.
