Communications management system
First Claim
Patent Images
1. A communications management system for use in conjunction with an externally-powered host computer for responding to communications signals on a telephone line, comprising:
- a power control means in the form of a relay, said relay being electrically connected to a power source and responsive to an applied control signal for supplying operating power from said power source to the host computer;
a printed circuit board connected to said host computer, said printed circuit board including control circuit means electrically connected to said power control means for supplying said control signal to said relay to power up said host computer, said control circuit means supplying said control signal in response to receiving the communications signals on the telephone line; and
means for processing information received over said telephone line following said power up of said host computer, said means for processing including an analog-to-digital converter operatively associated with said control circuit means and storage means for retrievably storing said information within either said management system or within said host computer, said storage means being electrically connected to said analog-to-digital converter.

Abstract
A communications management system for use in conjunction with a host computer includes independently powered processing circuitry which automatically powers up the host computer upon receipt of an incoming message, thereby avoiding the need for the computer to be continuously powered. In the event of a momentary power interruption during operation of the system a battery-powered clock and memory circuit within the system reestablishes the system upon resumption of power to the operating configuration which existed at the time of interruption.

6. A communications management system for use in conjunction with a host computer for responding to communications signals on a telephone line, comprising:
-
a printed circuit board connected to the host computer, said printed circuit board including signal processing means for responding to communications signals to establish the communications management system and the host computer at an operating state relative to the telephone line, and for storing such operating state information; a clock circuit including a battery back-up power source, said clock circuit being associated with said signal processing means on said printed circuit board; memory means for storing said operating state information, said memory means being operatively associated with said clock circuit and powered by said battery back-up power source; means for processing information received over said telephone line when said signal processing means has been reconfigured to said stored operating status, said means for processing information including an analog-to-digital converter operatively associated with said signal processing means and storage means for retrievably storing said information within either said management system or within said host computer, said storage means being electrically connected to said analog-to-digital converter; circuit means responsive to said memory means containing said stored operating state information for reconfiguring said signal processing means to said stored operating state; and said circuit means reconfiguring said signal processing means to said stored operating state following momentary power interruption. - View Dependent Claims (7)
