Abstract
The disclosure depicts in a two-way broadband communications network employing a carrier sense multiple access with collision detection protocol an apparatus and method for controlling station transmit signal levels. Signal level detection circuitry is coupled to one or a plurality of locations in the network transmission medium to determine the signal level generated by each of the plurality of stations periodically transmitting into the medium. The detected signal level from a station is compared to a predetermined range of appropriate values for the station and where the station is transmitting signals outside of the predetermined range, a correction factor is applied to the station to adjust the transmit levels of the station.
