Alarms/Errors Overview
FEC-UNCORR (FEC - Uncorrectable)
RX: Statistics on the detected codewords (CW) having uncorrectable
errors.
TX: FEC-UNCORR-CW (Forward Error Correction - Uncorrectable -
Codeword) generates 16 symbol (bytes) containing 8 bits in error each,
in each codeword.
FEC-STRESS (Forward Error Correction - Stress)
TX: Generates correctable errors composed of a random number of
symbol errors (less or equal to 8) containing a random number of bits
distributed all over the OTU frame.
MFAS (Multiframe Alignment Signal)
RX: The MFAS bits are in error.
QoS Metrics
Note: Available with Traffic Gen & Mon test application.
Errors
Frame Loss
RX: A sequence number is missing in the received frames.
Out-of-Seq. (Out-of-Sequence)
RX: The received frame sequence number is either smaller than the
expected frame sequence number or is a duplicate number.
