Description<br />
Use this element to set the alarm threshold value of the errored seconds ratio. The<br />
errored seconds ratio is the ratio of errored seconds to total seconds during a 15<br />
minute time interval. So if the errored seconds ratio …<br />
• exceeds this value within a 15 minute period 3 , then the errSecRatioExceeded<br />
alarm is raised.<br />
• drops below this value within a 15 minute period, then the errSecRatioExceeded<br />
alarm is cleared.<br />
Use this element to set the alarm threshold value of the severely errored seconds<br />
ratio. The severely errored seconds ratio is the ratio of severely errored seconds<br />
to total seconds during a 15 minute interval. So if the severely errored seconds<br />
ratio …<br />
• exceeds this value within a 15 minute period 3 , then the sevErrSecRatioExceeded<br />
alarm is raised.<br />
• drops below this value within a 15 minute period, then the sevErrSecRatioExceeded<br />
alarm is cleared.<br />
Use this element to set the alarm threshold value of the background block error<br />
ratio. The background block error ratio is the ratio of background block errors to<br />
total blocks during a 15 minute time interval. The count of total blocks excludes all<br />
blocks during severely errored seconds. So if the background block error ratio …<br />
• exceeds this value within a 15 minute period 3 , then the bBErrRatioExceeded alarm<br />
is raised.<br />
• drops below this value within a 15 minute period, then the bBErrRatioExceeded<br />
alarm is cleared.<br />
1. The central device is the device on which the channel attribute is set to central.<br />
2. The remote device is the device on which the channel attribute is set to remote.<br />
3. 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.
