Abstract:
Systems, methods and apparatus for operating an optical network terminal (ONT) in a passive optical network include maintaining an operational state in the passive optical network, estimating an upstream channel, adjusting equalization delay and physical layer frame offset values and switching from a backup mode to a primary mode of operation upon detecting a failure condition.
