Alarm attributes<br />
The alarm … is generated … Default<br />
value<br />
alarmMask<br />
alarmLevel<br />
signalNoise<br />
errSecRatioExceeded<br />
sevErrSecRatioExceeded<br />
when the signal noise exceeds the value<br />
configured in the line/linkAlarmThresholds configuration<br />
attribute of the local device for at<br />
least 10 seconds. The alarm is cleared<br />
when the signal noise drops below this<br />
value for at least 10 seconds.<br />
Note however that in case the line/eocHandling<br />
configuration attribute is set to alarm-<br />
Configuration, the central <strong>SHDSL</strong> device<br />
forces the remote <strong>SHDSL</strong> device and any<br />
intermediary repeater to use the linkAlarm-<br />
Thresholds/signalNoise as configured on the<br />
central device.<br />

when the errored seconds ratio exceeds<br />
the value configured in the line/linkAlarm-<br />
Thresholds configuration attribute of the local<br />
device within a 15 minute period 1 . The<br />
alarm is cleared when the errored seconds<br />
ratio drops below this value within a 15<br />
minute period.<br />
when the severely errored seconds ratio<br />
exceeds the value configured in the line/<br />
linkAlarmThresholds configuration attribute of<br />
the local device within a 15 minute period 1 .<br />
The alarm is cleared when the severely<br />
errored seconds ratio drops below this<br />

1. The 15 minute periods run synchronous with the 2 hour periods of the line/h2Line performance<br />
attribute. Because alarms are raised or cleared within 15 minute periods, there is a delay in the<br />
alarm status. For example, suppose that in the first minute of a 15 minute period the errSecRatioExceeded<br />
value is exceeded, then the errSecRatioExceeded alarm is raised when the full 15<br />
minute period has passed. The alarm is only cleared if in the next 15 minute period the errSecRatioExceeded<br />
value is not exceeded.<br />
The local configured thresholds are used to generate the errSecRatioExceeded alarm, the sevErrSecRatio-<br />
Exceeded alarm and the bBErrRatioExceeded alarm, so these alarms can differ from the alarms generated<br />
on the device at the other site of the line.
