This read-only Counter counts outbound packets that were chosen to be discarded even though no errors had been detected, for example to free up buffer space. An admin monitors this to detect outbound congestion or queue exhaustion on a DS0 channel that is being asked to send more traffic than it can handle. For example, a rising ctDs0ifOutDiscards count alongside a growing ctDs0ifOutQLen value would confirm the channel's output queue is overflowing under load.
