A modem (106) is arranged with a power control circuit (113) for controlling the power flow to the modem, based on the modem's data activity. After initial data activity is established (303), the power control circuit monitors the modem to determine when the data activity ceases. When the power control circuit determines that modem activity is no longer present (305), it releases a power-control relay (114), thus powering-down the modem (307). The power control circuit then continues to monitor the modem to determine when data activity returns. When the power control circuit determines that modem activity has returned (309), it operates the power-control relay, thus powering-up the modem (311). Normal data activity now continues (313).
