  • Power-down modem
    Patent number: 4951309
    Abstract: A modem capable of three modes of operation; a normal mode, a reduced power mode responsive to a control signal from a function controller within the modem, and a further reduced power mode responsive to a control signal from the computer. The function controller monitors activity within the modem and applies or removes power transparently as required to exit or enter the first reduced power mode. The control signal from the computer enables the modem to enter or exit the further reduced power mode, in which no modem functions are available.
