This read-only INTEGER reports whether Frame Discard is enabled (yes/1) or disabled (no/2) in the forward direction for this call, controlling whether the switch drops whole AAL5 frames rather than individual cells when discarding is necessary. An administrator checks this to understand the call's loss behavior under congestion: with frame discard enabled, a congested switch drops complete frames to avoid wasting bandwidth on already-corrupted partial frames. For example, an engineer diagnosing unexpectedly severe throughput loss on a congested call checks cwspCallFwdFrameDiscard to see whether whole-frame discard, rather than random cell loss, is amplifying the effective loss to the application.
