Classification: H04L

Abstract:
A data recovery system comprising:means for receiving a data signal;means for splitting the data signal into a data channel signal and a monitor channel signal;means for digitizing the data channel signal to obtain a data out signal;means for digitizing the monitor channel signal to obtain a monitor out signal;means for comparing the data out signal and the monitor out signal;means for adjusting the means for digitizing the data channel signal, the means for adjusting being responsive to a signal generated by the means for comparing the data out signal and the monitor out signal;wherein the means for digitizing the data channel signal comprises means for comparing the data channel signal to a data channel reference energy level to produce an intermediate data channel signal and means for periodically sampling the intermediate data channel signal, and the means for digitizing the monitor channel signal comprises means for comparing the monitor channel signal to a monitor channel reference energy level to produce an intermediate monitor channel signal and means for periodically sampling the intermediate monitor channel signal.
