299.0. "Interop with Fibermux 5500?" by IJSAPL::DEKKERS (Rob Dekkers EIS Holland) Wed Jul 17 1991 06:23

Looking through this notefile I didn't find a pointer to a
report (or publication) describing the results of testing our equipment
against other vendors FDDI. 

What is the status of this, is there (will there be..) a report describing
the results of these interop tests?

I'm asking this because I'm in a situation that I have to connect a
Fibermux 5500 (DAS bridge MM) to our concentrator (WC 500), which isn't working
out very well... 

I tried to setup the following topology


       +================+           +=============+
       |   Conc 500   a |-----------|b   Fibermux |          
       |   m          b |-----------|a    5500    |      
       +================+   MM      +=============+
           |                                |
           |                                |      Ethernet
           |                          --------------------
   +=============+
   |  DECbridge  |
   |    500      |
   +=============+
         |          Ethernet
    ----------------------


The result: 

   The Fibermux and the concentrator don't see each other on the ring (on PHY
   level). 
   So I'm very curious if there is someone out there who has tried
   to connect these Fibermux bridges to Digital's Concentrators.

Do you have more details?  What lights show  on the DEC side?  What does
ELMS have to say about the status and counters for those ports?

299.2Translating or Encapsulating?SYORPD::DEEPBob Deep @SYO, DTN 256-5708Wed Jul 17 1991 17:245
Also, is the Fibermux a translating bridge?  Shouldn't matter to the 
concentrator, but the DECbridge is sure gonna care!

299.3Some info..IJSAPL::DEKKERSRob Dekkers EIS HollandFri Jul 19 1991 12:1714
    Sorry, it took me so long..
    
    Connecting the fibermux to the concentrator immediatly turns
    on the red led on the A port of our concentrator. I don't
    have the exact status and counters of the concentrator ports
    (I will check those next week).
    
    .2 : The Dutch PTT (who is reselling the bridges) claims that the
         Fibermux bridges are translating. (We didn't have the 
         opportunity to check that out...)

299.4Is it solid red or blinking red?BAGELS::LEVYFri Jul 19 1991 13:152
    A solid red PHY LED indicates a Line Confidence Test failure. Perhaps
    you have a faulty cable?
