18 Confidential and Proprietary Information of ZTE CORPORATION
Detecting faults, and locating them in the line cards and
tributaries with an accuracy of one second.
Reporting all alarm signals and relevant details.
The alarm correlation, that is, when a higher-level alarm
is generated, the corresponding lower-level alarm should
be recovered. For example, the LOS alarm of the optical
interface board and the MS_AIS alarm of s4805.
Implementing the alarm filter function, which can filter
the repeated and redundant alarms.
Setting the alarm shielding function to shield the
detection of some alarms.
Setting the levels of the faults.
Reporting all or some alarms in the NE and the boards
and implementing the alarm synchronization function.
The NS board and the line cards do not store the history
alarm data. The alarm time is marked by the SMN.
Performance management module
Monitoring the performance of all NEs.
Implementing 15-minute, one-day and 15 minute zero
counter performance data with an accuracy of one second.
Setting 15-minute performance monitoring threshold and
one-day performance monitoring threshold, and reporting
one threshold exceeding event alarm in the current
counting period if the performance value exceeds this
threshold.
The NS board and the line cards don not store the history
performance data.
