Description: Increment counter by one for each carrier event whose ActivityDuration is greater than ShortEventMinTime and less than ShortEventMaxTime. ShortEventMinTime represents any event of sufficient duration to initiate transmission by a repeater. ShortEventMaxTime is greater than 7.4uS and less than 8.2uS. ShortEventMaxTime has tolerances included to provide for circuit losses between a conformance test point at the AUI and the measurement point within the state machine.

Note: shortEvents may indicate an externally generated noise hit which will cause the relay to transmit Runts to its other ports, or propagate a collision (which may be late) back to the transmitting DTE and damaged frames to the rest of the network. Such shortEvents are not a feature of normal network activity. Also it should be noted that a MAU that is attached to a coax segment may have several carrier dropouts on the DI circuit before the CI circuit is active and stable. Such dropouts will increment the shortEvent counter but are considered normal for a coax segment.
