Abstract
An optical network terminal includes a sleep logic circuit that assumes responsibility for monitoring off-hook transitions after the AC main power supply has failed for a predetermined period of time. The sleep logic circuit is very low power and, as a result, allows the optical network terminal to remain active and provide lifeline support for a much greater period of time.
