ABSTRACT:
An electronic dispatch board for use with a voice message recording-playback machine. The dispatch board lights certain lamps responsive to signals sent from the message recording-playback machine when a message has been placed in a certain voice mailbox. The dispatch board is comprised of a serial-to-parallel converter, a board address comparator, an address signal verifier, a lamp driver, and a plurality of lamps. The address signal verifier determines if a valid address signal has been received from the message recording machine. A number of dispatch boards may be simultaneously connected to the same message recording machine. The board address comparator in each dispatch board determines if the address signal from the message recording machine is meant for that particular dispatch board. If a valid address signal has been received, a certain lamp is set to an on, off or blink state.
