Field Description
BERT (bit error rate test) checks the quality of the line. This output appears
only when a BERT is run on the interface.
• BERT time period—Configured total time period that the BERT is to run.
• Elapsed—Actual time elapsed since the start of the BERT (in seconds).
• Induced error rate—Configured rate at which the bit errors are induced in the
BERT pattern.
• Algorithm—Type of algorithm selected for the BERT.
Active alarms and defects, plus counts of specific SDH errors with detailed
information.
• Seconds—Number of seconds the defect has been active.
• Count—Number of times that the defect has gone from inactive to active.
• State—State of the error. State other than OK indicates a problem.
Subfields are:
• PLL Lock—Phase-locked loop
• PHY Light—Loss of optical signal
Active alarms and defects, plus counts of specific SDH errors with detailed
information.
• Seconds—Number of seconds the defect has been active.
• Count—Number of times that the defect has gone from inactive to active.
• State—State of the error. State other than OK indicates a problem.
Subfields are:
• RS-BIP8—24-bit BIP for multiplex section overhead (B2 bytes)
• OOF—Out of frame
• LOS—Loss of signal
• LOF—Loss of frame

• RS-ES—Errored seconds (near-end regenerator section)
• RS-SES—Severely errored seconds (near-end regenerator section)
• RS-SEFS—Severely errored framing seconds (regenerator section)
