3262.0. "reductant-link support on DR90TS?" by SNOFS1::63496::CHIUANDREW () Sun Feb 11 1996 19:15

    Hi,
    
    Just want to confirm the function of DR90TS (running V2.0 firmware
    DETMI200.bin from DCF V4.1.2):
    
    1) Does it support the reductant-link feature, so that it can monitor
    the primary and secondary links as a master in a 3 DECrepeater 90TS
    loop configuration?
    
    we have this feature on PORTswitch900TP (as documented in dual-port
    redundancy - appendix B), our customer would have to use the
    DECstackable with 3 X DR90TSs to have full redundancy over UTP cable.
    
    Can it be done with DR90TS?
    
    
     
    thanks in advnace for help!

    No, the 90TS is unable to act as either a master or a responder for DPR
    configurations.  
    
    Like any 10Base-T repeater (even non-Digital), it can act as a
    non-responder, giving partial fault coverage.
    
    This is a hardware limitation of the chips around which the 90TS,
    900TM, and 900GM are designed.
