16–31 RCSE Receive false carrier counter. Counts the number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame on a particular interface.
The count represented by an instance of this object is incremented at most once per transmission attempt,
even if the carrier sense condition fluctuates during a transmission attempt. The event is reported along with
the statistics generated on the next received frame, as defined by a 1 on TSEC n _RX_ER and an 0xE on
TSEC n _RXD. Only one false carrier condition can be detected and logged between frames.

15.5.3.6.20 Receive Undersize Packet Counter (RUND)

16–31 RUND Receive undersize packet counter. Increments each time a frame is received which is less than 64 bytes in
length and contains a valid FCS and were otherwise well formed. This count does not include range length
errors.
