Abstract

A microprocessor/based telephone/facsimile controller which automatically gives priority to incoming messages. The ring voltage of an incoming message causes the microprocessor to close and latch the line between the telephone and the facsimile. When transmission is completed, the line is dropped and this condition is sensed causing the latch relay to open to prevent the facsimile from transmitting, no data being logged for incoming facsimile transmissions. Only a valid input code permits the coupling of the facsimile to the telephone line also initiating a timer. A broadcast mode latches the telephone line to permit delayed calls and multiple facsimile transmissions, each allocated to the user code which established the broadcast mode. A default time is utilized to accommodate the redial and use of the line for non-facsimile telephone transmission.
