Abstract
A remote line monitoring device and method for a CATV system in which a center facility is connected to plural terminal units through cables of the system to transmit television signals to subscribers' homes. A plurality of monitoring terminal units are provided along various points of the interconnecting cables. Each of the monitoring terminal units is identified by an unique address. To determine conditions throughout the system, a central monitoring system transmits polling signals on the cables. If an address contained within the polling signals matches with a prestored identifying address, a monitoring terminal unit responds by transmitting data produced by monitoring converter units back to the center facility. The center facility can then display the data or produce indications identifying problems along the cables.
