Abstract
An RF ingress/egress management system is made up of three major components. (1) A headend monitoring receiver, that is frequency tunable from 5 to 50 MHz, is capable of decoding and reading a unique tone that is transmitted and enters a cable flaw and is returned to the headend via the upstream coaxial plant. (2) A mobile transceiver global positioning satellite (GPS) system receives RF egress in the 50 MHz to 1 GHz region and stamps a GPS coordinate and stores that information. Also, a 5 to to MHz transmitter modulated with GPS coordinates transmits sufficient power to enter the cable television system flaw and be received at the headend location via the headend monitor. (3) A computer software system quantifies the cable flaw at egress and ingress frequencies and assigns a coordinate and figure of merit so that a repair technician can expedite repair of the coaxial plant.
