Sorry for using the word "pins". I do not know what is the equivalent of "pins" in fibre cables and connectors. Don't ask me why but I need the following information for something I am doing via a patch panel ? On the FDDI-MIC connected on the Management Card of a DEFCN take the PHY connector on the left and the PHY connector on the right hand side. Which pins are Prinmary In, Secondary Out, Secondary In, Primary Out. Same question as above for all our other MIC cards. Which pin is Transmit and which pin is Receive on the DEMFA bulkhead, F612 DECnis FDDI card, DEFQA, DECbridge 5xx, DECbridge 6xx, DEFCN-H*, DEFCN-HN*, etc. etc. DL3000 FDIM module too. Alphonse

Port A = Primary In, Secondary Out
Port B = Primary Out, Secondary In
Distinguishing between In and Out (for A,B,M or S):
(There's probably an easier way, but this is the best I could come up
with....)
Use an FDDI fixed-shroud-duplex connector plug. The shroud is not
symmetric with respect to the two pins: For one of the pins, the shroud
is physically closer to the pin than the other one. This "closer-in"
shroud, when inserted into a MIC receptacle, corresponds to the In (or
Receive) pin of that receptacle.
