The information, in the form of alarm or notiication, is stored in database or displayed on realtime basis via a user-oriented fault monitoring platform. Means such as visual-interface monitor or history information query can be used to view current or historical system operation and service processing status. Fault management enables maintenance personnel to troubleshoot and take preventive measures to remove potential fault and restore system and services as early as possible. Fault View Fault is displayed in the form of alarm or notiication. Alarm The fault that persists during system operation and affects system reliability and normal services is referred to as an alarm. Alarm usually lasts until fault removal. Due to its possible impact on normal system operation, alarm requires timely troubleshooting in which alarm cause is identiied, and the fault is located and handled. Conidential and Proprietary Information of ZTE CORPORATION 1 ZXWR RNC Alarm and Notiication Handling Reference Notification Notiication refers to the non-repeated/instantaneous fault or event that occurs during system operation. Examples include board reset, signaling overload, etc. Notiication is mostly caused by sudden environment change or other accidental factors. No special handling is required for the notiication, which can be automatically removed by the system. Only the notiication that occurs persistently requires troubleshooting. Alarm Alarm Property Alarm Code Alarm code is the identiier which differentiates alarms. Alarm code is deined by a 32-bit ield indicating the speciic code value. Description Alarm description relects such content as fault cause and fault phenomenon in a simple and straightforward way. Severity There are four alarm levels, which are indicated in descending order of severity as Critical, Major, Minor, and Warning. � � � � 2 Critical alarm causes system breakdown and service interruption. It requires immediate troubleshooting. Major alarm signiicantly affects system operation or weakens network service capability. It requires troubleshooting as soon as possible. Minor alarm affects system operation and network service capability in a nonsigniicant way. It requires timely troubleshooting so as to avoid severity escalation. Warning poses a potential hazard to system operation and network service capability. It requires troubleshooting at an appropriate time so as to avoid severity escalation. Conidential and Proprietary Information of ZTE CORPORATION Chapter 1 Overview The degree of impact as described in the deinition of alarm severity refers to the impact of a single index, such as reliability and security. Once the impact on any of the index reaches the speciied threshold, the severity level of the alarm can be roughly determined. If an alarm has an impact on multiple indices, alarm severity should be escalated accordingly. Note: Alarm severity can be modiied in NetNumen M31 NMS (network management system) if necessary. Generally speaking, the default alarm severity is reasonably set. Users should think twice before making any modiication. In addition, the severity of few alarms is undeined. It is up to users to deine the severity of such alarms. Alarm Type Alarm is classiied into six types according to alarm trigger condition and its system impact. � Equipment alarm: related with device hardware. � Processing alarm: related with software or process fault (ITU-T Recommendation X.733). � � � � Communication alarm: related with information transmission (ITU-T Recommendation X.733). Environment alarm: related with the environment where the equipment is located (ITU-T Recommendation X.733). QoS alarm: related with degradation of service quality (ITU-T Recommendation X.733).
