摘要： A communication system includes an interface that allows a media access controller (MAC) and an optical line termination transceiver module (TM), which have incompatible interfaces, to be connected together. The interface detects a phase relationship required by the TM, and feeds the information back to a processor and memory which places a value into the MAC to adjust the phase relationship.

摘要： 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.

摘要： A battery backup unit (BBU) includes a housing, at least one battery compartment in the housing with an output terminal, a DC input, a DC output, a path from the DC input to the DC output, circuitry for selectively connecting the output terminal to the path, which circuitry includes a switch, and a controller configured to detect a condition of the path and selectively control the switch to connect the output terminal to the path when the condition is detected, the BBU being incapable of charging batteries in the at least one battery compartment. The path from the DC input to the DC output may include a DC/DC step up converter to help maintain a constant output voltage.
