Abstract

A communication network (10) has a memory unit (20) accessable to all ports (16-0, 16-1, 16-2, 16-3) of the link with a plurality of local sections (62) each associated with one of the ports. Interconnections include a dual memory bus (28) with a common bus subsystem (36) providing access to a common memory section and a local bus subsystem (30) providing access to the local memory sections, the subsystems constructed to permit concurrent independent use. Memory access priority circuitry (68) designates for each memory operating cycle a port for current service and makes memory access available to other elements when not required by the designated port.
