Abstract: A computer controlled, data communications system is provided for transmitting data between a plurality of external devices. The system comprises up to eight, general purpose, digital computers, each with an associated disc-file storage system. The computers and the disc-file storage units are organized such that communication between the computers is made via the disc-file storage associated with each computer, not directly between the computers themselves. Each group of external devices is coupled to a primary and secondary computer such that upon the failure of the primary computer, the secondary computer will procss the data for its primary group of devices as well as for those external devices for which it is the secondary computer. Each disc-file storage unit is the primary storage for one computer and the copy storage for one additional computer. Upon the failure of a primary disc-file storage unit, a computer can operate with the copy storage unit.
