The FOT can be connect together by a fiber cable and both end could be connect to a Ethernet Interface through the AUI cable. This setup will connect two AUI ports together. You can look at it this way. The fiber is like your Thickwire Ethernet cable and the FOT is your transciver that tap into the cable. The FOT can work independently without the FOMIM board and the IRM. -- Hock-Koon Lim, Information Network services Case Western Reserve University; Cleveland, Ohio, USA 44106 (216) 368-2982 lim@ins.cwru.edu
