摘要

The present invention provides a method and apparatus for controlling power consumption and access to telephone channels (36) in a cable telephony system (10). The system (10) has two subsystems for limiting power and access, one, when a telephone (40) is waiting to receive a call and a second when a subscriber wants to place a call. The telephone (40) is usually waiting for a telephone call. The first subsystem reduces power consumption by having a transceiver (114) for the telephone (40) only monitor for incoming calls periodically and turns off the transceiver (114) when not monitoring for calls. The second subsystem, limits system power consumption and access to channels (36) by only allowing loop current and access to channels (36) when a channel (36) is available for use. These two subsystems reduce the system power consumption and regulate the access to the telephone channels (36).
