1556.0. "Will these FDDI-configs work??" by EEMELI::SOHLMAN (Jouko Sohlman , NIS Helsinki Finland) Wed Oct 12 1994 07:50

	Hello !

	Is the following configuration legal and functional, if yes
	could I put also a workstation with DAS-connection in place
	of the DECswtich 900EF?


			Thanks in advance

    Perfectly legal.  The concentrators are both on the dual ring and the
    DECbridge (er, DECswitch) is dual-homed to the two concentrators.  You
    can replace the DECswitch with another DAS device and accomplish the
    same thing (dual homing).
