1102.0. "CDDI I/F card ???" by TKOV51::AOKI_H (Hiromitsu AOKI, Network Team/SE, Japan DEC) Mon Oct 04 1993 03:40

There are various FDDI I/F cards as follows :

      - FDDIcontroller/TURBOchannel      (DEFTA) 
      - FDDIcontroller/Q_Bus    	 (DEFQA)  
      - FDDIcontroller/EISA  	 	 (DEFEA)  
      - FDDIcontroller/Futurebus+   	 (DEFAA) 
      - FDDIcontroller400                (DEMFA) 
      - FDDIcontroller/700-C             (DEFZA)  

I heard CDDI is the same as FDDI in protocol exept for cable only, fiber
optics or copper. Which of the above I/F cards support CDDI ? 
Is there any difference from fiber when conecting cable ?

	CDDI is crescendo's proprietary solution to copper-based FDDI. Is what customers really want is a standard solution to copper-based FDDI (the TP-PMD standard). We are current testing that on the EISA FDDI adapter, and I hear we might be doing that for the Turbochannel FDDI adapters as well. For more information, dates and prices contact the appropriate product manager: EISA: Sharon O'Neill TURBO: George Nielsen doug
