A read-write Unsigned32 setting the number of Degraded Codeword Seconds permitted within a one-hour operational window before the p2mpSuDegradedSecAlarmTrap is generated. Since degraded seconds represent the mildest tier of link impairment, this threshold typically allows a higher count before alarming compared to the SES and CSES alarm thresholds, catching only sustained or worsening minor degradation. For example, an admin might tolerate a moderate p2mpSuLink1HrDCSAlarmThresh during a known period of seasonal rain fade, only escalating on the stricter SES-based alarms.
