ABSTRACT:
A stored program energy control system operates with the control of a telephone communications system to improve its energy efficiency by removing power from station sets and their associated visual indicators when they are inactive. Inactive station sets are identified by establishing minimal intervals of nonuse to define the inactive status. The energy control system responds to events like incoming calls and switchhook activity to restore power to the station set. Since energy is applied to a station set only when precisely needed, the overall energy drain of the system is greatly reduced.
