摘要: The invention disclosed is a system for receiving, storing and retransmitting voice messages. includes plurality of digital computers operating independently in parallel to supervise the system's operation. also conversion subsystem which telephone lines may be connected. converts between analog signals data uses message storage. semi-autonomous sub-subsystems, one per line connected system. Each sub-subsystem microprocessor random access memory microprocessor's program temporarily digitized data. monitors status controls operation sub-subsystem's stored within mass storage messages indefinitely. Multiple, transfer paths interconnect each individual are presence these multiple, over transmitted adapts highly reliable further enhanced by means error detection multiple simultaneous selection. This selection detecting automatically instantaneously terminates if an detected.
