Abstract

A communication control unit provides an interface between a node apparatus of a lattice communication network and a terminal in conformance with a token ring network standard. The communication control unit includes a first memory for temporarily storing an input frame from the terminal, a second memory for temporarily storing an input frame from the lattice communication network, an input signal discriminator for discriminating a MAC frame which is used for ring management from the input frame from the terminal, a controller for controlling operation timings of at least the first and second memories, and a return path for returning the MAC frame to the terminal with a priority over other frame when the input signal discriminator discriminates the MAC frame.
