Minor Alarms:
Config Error – If ALARM appears on this line, the card has detected a checksum error in
the memory where the configuration is stored.
Loss of Cell Delineation – If a loss of cell delineation has been detected on the port, an
A (for Alarm) appears in the column for that port.
Loss of Signal – If a loss of signal has been detected on the port, an A (for Alarm)
appears in the column for that port.
Loss of Power – The endpoint (ATU-R) has lost power.
Loss of Frame – A Loss Of Frame (LOF) condition exists. A LOF is declared after
approximately 2 seconds of contiguous Severely Errored Frames (SEF).
Loss of Signal Quality – A Loss of Signal Quality (LOSQ) condition exists. A LOSQ
condition exists when the noise margin falls below the minimum noise margin (0 dB) or
the BER exceeds 10
-7
for 3 seconds, or when the rate falls below the minimum configured
rate for 3 seconds.
Error Seconds Threshold –The number of Errored Seconds has exceeded the
user-defined threshold.
Severely Errored Seconds Threshold – The number of Severely Errored Seconds has
exceeded the user-defined threshold.
Unavailable Seconds Threshold – The number of Unavailable Seconds has exceeded
the user-defined threshold.
