Utilizing Ingress as a Plant Maintenance Strategy (1998)

By Raymond J. Schneider

A new concept is described which uses a transmitter located in the return path frequency interval to ingress coded signals into the system. A vehicle equipped with a GPS, a leakage detection system and a transmitter sends information, via coded ingression, back to a monitoring device at the head-end creating a centralized leakage and ingress database as a by-product of the maintenance cycle. We describe a prototype system used to test out these concepts. Data is presented on a small model cable system used to initially prove out the system. More definitive data will be developed on a portion of the Time Warner system in Harrisonburg.
