COMPUTER INDEPENDENT DATA CONCENTRATORS

摘要

A multiplex data concentration system for interconnecting multiple users at a single station with a remotely located digital data processing system over a single data channel (such as a telephone line) without modification to the data processing system or the data processing system side of the line. A major feature of the system is a unique data concentrator which is located on the user station side of the data channel, and has a plurality of user data interchange devices (such as teletypewriter devices connected as inputs and an output connected to the data channel. The concentrator includes preassigned data storage areas corresponding to each data interchange device and utilizes identification characters to prefix data sent to the data processing system for proper routing and processing within the data processing system. An appropriate application (user's) program enables the data processing system to process the data appropriately and to prefix transmitted data with similar identification characters to enable the concentrator to route the processed data to the appropriate user.
