Abstract
An interface circuit for a subsystem-controller is used in a data communications network. The interface circuit has a first (DLI) data link interface logic unit which includes a PROM sequencer which, when initiated by a master processor in the subsystem, acts to transfer data between a main host computer and a shared memory unit in the subsystem-controller. The interface circuit further includes a second (MLI) message level interface logic unit which is controlled by a slave processor (NDL) through the master (MLI) processor and functions to edit, translate and manage protocols for data transferred to and from a selected line communications processor which services a plurality of remote terminals.
