Concepts

Concept Description

Alarm ID Unique identifier of an alarm in one product.

Alarm Name Unique name of an alarm in one product. Alarm names clearly and accurately indicate alarmmeanings. There is a one-to-one mapping between alarm names and IDs.

Alarm Type There is only one alarm type: fault.

Alarm Level Impact of an alarm on service quality. There are four alarm severity levels: critical, major,minor, and warning.

Critical alarm: affects service quality. If a critical alarm is generated, immediateactions are necessary even when the fault occurs during non-working hours.Major alarm: affects service quality and requires immediate action during workinghours.Minor alarm: generally does not affect service quality, but requires handling orobservation in a reasonable amount of time to avoid more serious faults.Warning alarm: indicates a potential error that may affect service quality. Itrequires different actions depending on errors.

Event Type There are 16 event types based on monitored objects.Power alarm: relates to the power system.

Concept Description

Environment alarm: relates to equipment room environment variables, such astemperature, humidity, and door control.Signaling alarm: relates to channel associated signaling (for example, SS1) andcommon channel signaling (for example, SS7).Trunk alarm: relates to the trunk system, including trunk circuits and boards.Hardware alarm: relates to hardware, such as the clock unit and CPU.Software alarm: relates to software.System alarm: generated during system operation.Communication alarm: relates to communication.Service quality alarm: relates to service quality.Unexpected operation alarm: generated when an exception occurs.OMC alarm: generated when the OMC is not working properly.Integrity alarm: generated when information is illegally modified or deleted.Operation alarm: generated when service is unavailable or inaccessible becauseof inappropriate operations.Physical resource alarm: generated when physical resources are damaged by asuspected security attack.Security alarm: generated when security service or a security mechanism hasdetected that the system encounters security attacks.Time domain alarm: generated when an event occurs at an unexpected orforbidden time.

Description Conditions in which an alarm is generated.

Parameters Parameters related to alarms.

Impact on theSystem

Impact of an alarm on the system or services.

System Actions Actions taken by the system when an alarm is generated.

PossibleCauses

Issues that may result in an alarm. Possible causes are categorized into data configuration,hardware, software, and other causes.

Procedure Procedure for clearing an alarm step by step.

Change History

This alarm is reported when the mains input is out of range.

Parameters






34 de 526 13/11/2012 9:15


Specific Problem Specific Problem of the alarm(AC Failure, AC Phase Loss, AC Overvoltage, ACUndervoltage)



Major In the case that AC failure or AC phase loss occurs:If batteries are configured, the NE is powered by batteries and operates normallyuntil the batteries are depleted. If Load Low Voltage Disconnected (LLVD) isenabled, the load is powered off when the LLVD threshold is reached. In this case,the ongoing services carried on the load are disrupted.In the case that AC undervoltage occurs:The DC output power decreases and therefore some boards are powered off. In thiscase, the life span of power system is shortened.In the case that AC overvoltage occurs:The power module may stop providing power. Some boards may be powered off. Inthis case, the life span of power system is shortened.

System Actions

None

Possible Causes
