ABSTRACT:
A message handling system includes a computer controlled message processor for use in network configurations to store and forward low-speed messages between long distance and international communicators. Its use is based on dial-up connections between network nodes. Each message handler unit includes a microprocessor, program and buffer storage memories, line multiplexing circuitry, modems and input/output peripheral devices. The message handler unit may comprise a 32 port system, 30 of which are used as input ports and two of which are used as high-speed output ports. A journal of all message numbers is maintained on a printer for complete message accountability.
