Am I the only one who got "overly complicated" and read the part where the CATV installer ran all new wiring to the first floor outlets? If he did so, and ran his own drop to feed this service, where would anyone with half a brain find it appropriate to disconnect wiring that is totally unrelated to the wiring for the existing second floor wiring? According to Hal's original post, if I understood correctly, there was only existing wiring there for the second floor of the house.
Dunno Ed. I am no where near there (she's out on Long Island and you know where I am) so I can only speculate from what she told my wife. I can't see why an installer would disco another subscriber unless he thought some wiring was dead and he could reuse it for his job.
