Abstract
A computer having a modem outputs a telephone bell signals regardless of an active state of the computer as well as the modem. The modem provides a voltage signal responsive to the active state thereof. The computer system includes a bell signal generator for producing a bell signal in response to a ring signal received over a telephone line connected to the modem. Further, a relay switch is provided across the telephone line directed to the bell signal generator, the relay switch comprising normal-on switches allowing the telephone line to be connected to the bell signal generator when the modem is inactive state, and being activated to cut off the switch in response to the voltage signal fed from the modem. A speaker is connected to the output of the bell signal generator. If a telephone set is not connected to the modem, the computer of this invention may detect the telephone ring signal and sound a bell signal even if the computer as well as the modem is not in the active state.
