Telecommunications power distribution systems, telecommunications power distribution circuits and methods of supplying power to at least one telecommunications device

摘要

According to a first aspect of the invention, a telecommunications power distribution system includes a main power source; a reserve power source; a telecommunications device connection adapted to supply power to at least one telecommunications device configured to perform at least one operation with respect to telecommunications; a switching device configured to selectively couple the reserve power source device with the telecommunications device connection; and a lockout circuit configured to monitor an electrical condition of at least one of the main power source and the reserve power source, and to control the switching device responsive to the monitoring. to perform at least one operation with respect to telecommunications; a switching device configured to selectively couple the reserve power source device with the telecommunications device connection; a power controller configured to selectively provide a power control signal to control the switching device to couple the reserve power source with the telecommunications device connection; and a lockout circuit configured to selectively prevent the power control signal from controlling the switching device responsive to an operational condition of the telecommunications.
