ABSTRACT:
Two-way links communication capability between time-division multiplexed subsystems is provided via dual time division address and data busses correlated by a recirculating memory having sections respectively associated with the address busses. Addresses on the address busses are recognized by the individual subsystems and further decoded to gate data to and from the busses data according to time slots assigned to terminal devices in the subsystems. The dual bus arrangement provides a full-duplex link in the sense that there is simultaneous communication via the two data busses, one each way.
