Local Area Communication Network

The invention is a communications network for providing full-duplex data transfer between any two network interface units on a one-to-all-others contention bus. Network interface units (NIUs) send and receive data signals on outgoing and incoming links, respectively, which are connected to junction boxes which couple the incoming link connected to one network interface unit to the outgoing links of only the other NIUs. The data signals have source address codes and destination address codes applied thereto; those codes are examined by each NIU receiving a data signal to determine (1) if the NIU will accept the data signal for processing and (2) if full duplex data transfer is occurring. Transmission of all data signals in the network is temporarily aborted when any two NIUs are transmitting data signals and at least the signal transmitted by one of the NIUs is not addressed to the other NIU.
