Configuring and Monitoring through the LCD
Alarm thresholds determine the level at which an alarm condition is reached. There are two types of HDSL alarm thresholds:
•Link ES threshold determines the number of errored seconds that must 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.
