Description
Selects whether the alarm is disabled (DIS), or enabled and reported as a Minor (MIN) or Major
(MAJ) Alarm when the margin falls below the threshold. This indicates a potential degradation of
line quality. If an alarm is configured as a protection switch (PSW), it will behave as a Major (MAJ)
Alarm, and cause protection switching to engage.
Selects the margin alarm threshold (from 0 dB to 15 dB) for all four margin measurements of the
span.
Selects whether the alarm is disabled (DIS), or enabled and reported as a Minor (MIN) or Major
(MAJ) Alarm when 24-hour ES count exceeds the threshold.
Selects the errored seconds threshold (0 to 255) for all four errored seconds measurements of the
span measured over a 24-hour period.
Selects whether the alarm is disabled (DIS), or enabled and reported as a Minor (MIN) or Major
(MAJ) Alarm when the LOSW condition (HDSL loop down) occurs.
