Alarm
Parameters
The Alarm Parameters screen (Figure 4-10) allows reviewing and setting alarm
related thresholds for the selected element. These thresholds are the minimum
acceptable performance levels. To modify the parameters, highlight the desired
statistic, type in the new value (any number from 0 to 900) and press Enter. If this
value is later surpassed, an alarm indication appears. A field set to 0 causes the
element not to alarm on that statistic.
If alarm thresholds are edited from the front panel, the corresponding values are not
reflected on this screen until it is exited and then reentered.
Errored Seconds
A one-second period in which at least one logic error occurred.
Severely Errored Seconds
A one-second period in which at least 320 CRC errors or 1 OOF (out -of-frame)
occurred.
Loss of Signal Seconds
A one-second period in which the T1 received signal is interrupted.
Unavailable Seconds
A one-second period in which consecutive severely errored seconds cause an
unavailable state.
DTE LOS/ LOF Seconds
A one-second period in which the T1 received signal (on the optional T1 DTE
interface) is interrupted or the amplitude drops below a certain level.
