Configuring Alarm Thresholds

occur to trigger an alarm. This threshold can be set to 17 or 170 errored
seconds. You can also disable this alarm.
• Margin threshold determines the margin, in dB, that triggers an alarm.
This threshold can be set anywhere between 1 dB and 25 dB, in 1 dB
increments. You can also disable this alarm.
