To eliminate problems caused by the use of batteries for back-up power in outside plant facilities of a communication network or the like, the batteries are replaced with flywheel reserve power systems, in accord with the invention. Specific applications of flywheel power systems include flywheel systems to supply power to the optical terminal of a digital loop carrier type system, for a telephone network. Other applications relate to flywheel systems to supply power to optical network units (ONUs) in fiber to the curb or fiber to the home type communication networks. In the preferred embodiments, the flywheel power systems include intelligent components for monitoring and controlling operations of the power systems. Communication links are provided, to enable the monitoring and control components to report status to and receive control instructions from a centralized network control or management center.

[ What is claimed is:] [1.]1. Outside plant equipment having reserve power, for use in a communication network, said outside plant comprising:an optical terminal for terminating an optical fiber communication link of the communication network and providing communication services over links to customer premises, the optical terminal having a control circuit coupled to a power supply circuit receiving mains generator power; anda flywheel power system having a flywheel module and a flywheel electronics module, the flywheel system being mounted in proximity to the optical terminal, the flywheel electronics module electrically connecting to the control circuit;wherein the flywheel module is for receiving the mains generator power to reach and maintain rated speed, and upon disruption of the mains generator power such that the mains generator power falls below a threshold, the flywheel electronics module triggers the flywheel module to supply electric current as reserve power to the power supply circuit of the optical terminal.
