Packets or data units and their related credit returns each include an assigned phase value. When a credit test is desired, the phase value of outgoing data units is changed, for example from 0 to 1, and a new counter is set to a value of the outstanding credits having the original phase value. With each original phase credit received, the counter value is decremented. When a credit having the new phase value is received, the counter value indicates the amount of any credit error and appropriate corrections may be made.
