John H Hart, Frederick J Baker: Method and apparatus for bridging local area networks. Vitalink Communications Corporation, Donald C Feix, November 10, 1987: US04706081 (149 worldwide citation)

A communications system interconnects local Area Networks (LAN's) across broadcast simplex channels. The LAN's are connected independently and transparently of protocols above the data link layer so that the system appears to the user at a station in one Local Area Network as one large single networ ...

John H Hart, Frederick J Baker: Method and apparatus for interfacing to a local area network. Vitalink Communications Corporation, Donald C Feix, February 28, 1989: US04809265 (20 worldwide citation)

A controller for a bridge interconnecting local area networks operates in two modes. In a first mode the controller receives and transmits station data frames with previously appended frame check sums. In a second mode the controller responds to requests for information from stations by generating d ...
