ABSTRACT:
A method and apparatus are provided for monitoring power loss in a telecommunications system. Power is received from a permanent power source. A loss of power from the permanent power source is detected. Responsive to the detection of loss of power, a message indicative of a power failure is transmitted at least once on an optical fiber, the message transmission being powered by a temporary power source.
