Alarm Code Definition An alarm code is defined by a string of 32 bits, which indicates the code values of a specified alarm message. The range of GSM BSS alarm codes is as follows: 1 ~ 1009 198000000 ~ 198065535 198066000 ~ 198079999 198087000 ~ 198089999 Alarm Severity Level Whenever there is a problem or fault during BSC operation, an alarm message appears. Usually, the alarm may last till the problems or faults are rectified. According to severity, alarms are divided into four levels: Critical (level 1) Critical alarms cause the whole system to fail to operate or provide services. Measures must be taken to recover or eliminate the alarms immediately. Severe (level 2) Severe alarms greatly affect the system operation or result in severe degradation in performance of service provision. Measures must be taken to recover or eliminate the alarms as soon as possible. Confidential and Proprietary Information of ZTE CORPORATION 3 ZXG10 BSS (V6.10) Base Station Subsystem Alarm Handling Manual Major (level 3) Major alarms do not greatly affect normal system operation and performance of service provision. Measures should be taken to recover or eliminate the alarms in time to avoid more severe alarms. Minor (level 4) Minor alarms have potential effects on normal system operation and performance of service provision. Diagnosis and measures should be taken to avoid more severe alarms. In alarm level definition, the affected range only refers to the influence on a single item, that is, alarm level can be determined if a certain index, such as reliability and safety, reaches the specified range. If an alarm affects several indices, the alarm level should be upgraded. Note: Alarm levels can be modified in the Netnumen M31 EMS system based on the actual situations. Generally, the default settings are comparatively reasonable. Be cautious when re-defining levels. It is not allowed to modify the settings at will. In addition, some alarm levels are not defined. For these alarms, users can define their levels in actual situations. Alarm Handling Pay attention to the following points when handling alarms: After noting down the problem and symptom, system maintenance personnel should handle the alarms step by step by referring to the solutions described in this manual. Unless otherwise specified, end the alarm handling once the fault is rectified (that is, the alarm is recovered), or go to the next step if the problem persists. If the alarm fails to be handled or recovered, contact the local ZTE office. Alarm Classification The BSS related alarm messages on Netnumen M31 can be classified into the following six types: 4 Equipment alarms Confidential and Proprietary Information of ZTE CORPORATION Chapter 1 Alarm Message Summary Communication alarms Handling alarms Environment alarms QoS alarms EMS alarms Confidential and Proprietary Information of ZTE CORPORATION 5 ZXG10 BSS (V6.10) Base Station Subsystem Alarm Handling Manual This page is intentionally blank. 6 Confidential and Proprietary Information of ZTE CORPORATION Chapter 2 Alarm Messages This chapter gives a comprehensive and systematic description of the BSS (V6.10) related alarm messages, which helps system maintenance personnel to have a clear idea about every alarm generated at the BSS side.
