Abstract: Disclosed are systems and methods to provide energy control via power-requirement analysis and power-source enablement. Both demand-side and supply-side techniques are used alone or in conjunction to determine an optimal number of power sources to supply power to one or more loads. When fluctuations in power requirements are present, measures such as decoupling less-critical loads in order to continue delivering power to critical systems and turning on and off power sources as needed to meet the current power demands of a system are implemented. Power sources are periodically deactivated by the system on a rotational basis such that all power sources wear evenly, prolonging the life of the equipment. A scalable architecture that allows the virtualization of power from the underlying hardware form factor is also provided.

Abstract: An architecture for providing interactive broadband products and services uses existing cable and telephone plant. The architecture includes a central office switch in communication with a head-end server and a Customer Premises Equipment (CPE) device such as, for example, a modem emulator, data terminal, set-top terminal or personal computer. The CPE device is provided in communication with the head-end server via cable plant for downstream broadcasts and is further provided in communication with a central office switch via telephone plant for upstream signaling and downstream control messages.

Abstract: A method and system for determining the required number of active video circuits in an interactive video delivery network required to meet the specified blocking probability constraints. By determining peak loading hours as well as the number of system subscribers in a given video delivery network, the user may determine the blocking probability of the interactive video delivery system in accordance with the formula: ##EQU1## This information may thereafter be used to determine the number active video circuits to meet the determined blocking probability.
