The house was built in the 80s, the development was built the same time period. It is an odd situation. From what AT&T told me it is phone what the homeowner told me is TV.
Can you see any markings on the cable? Most cable is imprinted with specifications every few feet.
The cable has the following marking: SUPERIOR ESSEX T 06/24/12 2X22 BW NS 670 FEET
