Abstract
A multiple port signal regenerator for facilitating communication between a plurality of (two or more) computers and computer peripheral devices ("computer products") in a local access network. The regenerator includes logic circuits that: (1) receives, processes and transmits an incoming message from a source computer product and ignores subsequently received incoming messages from other computer products until the first-received message is processed; (2) suppresses or ignores, for a predetermined punishment time interval, subsequent messages received from a source computer product, if temporal length of a message received from the source exceeds a predetermined protocol time interval; and (3) after the end of a message is received, determines when the lines of a network are all idle so that the regenerator can be re-activated to receive another incoming message from a computer product in the network.
