1352.0. "TAXI - What do we have in this area?" by CUJO::HILL (Dan Hill-NetMgtConsult-Denver-553-3624) Tue May 31 1994 13:13

    Greetings,
    
    Would someone kindly elaborate on TAXI?  This is supposedly a
    synchronous transmit/receive interface for FDDI.  I have been unable to
    find documentation on this.  I'd like to learn more.
    
    Do we have a TAXI card for any of our systems?  If so, would anyone
    happen to know the product manager?
    
    Thanks,
    Dan

	TAXI is NOT FDDI. TAXI is an AMD proprietary point-to-point channel. It runs at 100 Mb/s, and uses some small pieces of FDDI design. For example, it uses the FDDI symbol encoding and clocking. But it doesn't use FDDI frames (more precisely, TAXI has no defined frame structure, it's defined by the application) and it does not even use FDDI Idle symbols between frames... TAXI is nice if you want a 100 Mb/s serial channel, but it has no practical connection to FDDI. paul
