Abstract:
A method for controlling a channel in a hybrid fiber coax (HFC) network, the method comprising:monitoring n-bit words transmitted over the channel over a period of time;counting a number of parity errors detected in monitoring the n-bit words over the period of time;deriving a probable bit error rate based on the counted number of parity errors;comparing the probable bit error rate over the time period to a pre-determined bit error rate value to determine if the channel is corrupted; andincreasing transmission power of the channel if the channel is corrupted without exceeding a total system power limit for the HFC network.
