Fibre Channel/Fiber Connectivity (FICON) cards when the congestion prevents the GFP transmitter from
sending frames to the card port. For example, the alarm can be raised when an operator configures a card to

FC-NO-CREDITS is raised only if transmission is completely prevented. (If traffic is slowed but still passing,
this alarm is not raised.)
