Message communication system

摘要

A message communication system which provides instant messages and memoranda at a telephone user's desk. In an office complex, a message is transmitted over pre-existing office power lines to printers located in a user's office and is automatically posted with time of day, date and sequence number. When a telephone call cannot be completed, messages are entered at the terminal by a telephone operator or message attendant. A computer automatically formats message forms and stores the text on a magnetic diskette. Messages are transmitted to outlying printers and can be recalled for display or resending at any time.
