The number of alarms is too large.

Once in a central office, thousands of alarms were generated in a day, which was inconvenientfor the customer to focus on the key problems.

The alarms are not accurately defined, resulting in poor guidance.

Some alarms are minor, but are defined as critical alarms. In this case, the number of criticalalarms is large, so the workload for handling the critical alarms is heavy; meanwhile, it is difficult

to use these alarms. The points of failure indicated by some alarms are ambiguous, so that it isdifficult for the customer to understand and troubleshoot them. As a result, the troubleshootingefficiency is low.

The guidelines in the documents matching the alarms for handling the

alarms are not as clear as possible.

The possible causes of some alarms are neither clear nor complete. Meanwhile, the procedurefor handling the alarms in different situations is not described step by step. Therefore, it is verydifficult for the customers to understand the alarms and troubleshoot the related faults accordingto the guidelines.

The alarms are not managed in a unified way.

The developers fail to comply with the alarm change control procedure, and they add or modifyalarms without authorization. As a result, a large number of redundant alarms exist in the alarmslist and in the equipment.

Present condition

Improvement on

Alarm Reference

In the past, the most impressive thing about the alarms for the access equipment was what a largenumber of the alarms! As a result, it was taken for granted that the maintainability of the alarms was poor.There is a procedural guide for the alarm change control, but the related restraint mechanism is notavailable. Therefore, the implementation is not satisfactory. Now, by optimizing the alarms and introducingthe change control tool, the access network has taken the lead in alarms in the network product line.

Key words : sharp increase in the number of alarms, separating events fromalarms, change control, and unified alarm library management.

After optimization

The alarms are defined according to the rules.

The notification of the system after its detection of a fault is defined as an alarm. The normal conditiondetermined by the customer or the active notification of the system for the customer when the system worksin the normal state is defined as an event. When an alarm occurs, the customer is generally required totroubleshoot the fault according to the related handling procedure so that the alarm can be cleared. Anevent, however, need not be cleared.

The information about the alarm is correct and complete.The attributes of an alarm are complete and match the related fault.

The alarm can be cleared because the related fault can be rectified according to

the handling procedure in the alarm reference.

The handling procedure in the alarm reference is written in the step-by-step way, so that the fault can berectified quickly.

The information about alarms can be filtered according to various conditions.

The alarms can be filtered according to different parameters. For example, you can filter an alarm in allscenarios by its alarm ID, or you can filter an alarm on a certain port.

The alarm store will not be generated.Upon the system alarm optimization, the traffic of alarms that are reported during a short period of time isstable, and no burst traffic will be generated, which prevents the alarm storm.

The number of alarms is evidently reduced.

After the system alarm optimization, some alarms that are not clearly defined are deleted or combined. As aresult, the number of alarms is reduced by 40% in comparison with the earlier version.

The alarms are managed in a standardized way and the change is under control.

The alarm baseline is created and the alarms for all the versions are managed in a unified way by theResman tool. The application for changing an alarm must be filed through the Resman tool for review bythe experts in the related fields. The alarm library, alarm codes, and alarm document are updated

Improvement onCommand Reference

The new Command Reference is a new experience to you. We are confident that theCommand Reference can be an indispensable assistant to your work!Key words: Command Reference, function, parameter description, and usageguidelines

Origin

The Command Reference is the document that is used most frequently. Its contents, however, are too simple to be aguide to the operations. In this case, the customers lose confidence in using the document. As a result, the customersatisfaction with the document is low.The major problems concerning the Command Reference are as follows:

The command functions and parameters are not clearly described, so the document cannot be a guide to theoperations.

The use guidelines are too simple to instruct the customers to perform the related configurations.

Analysis of major problems concerning the Command Reference:

1. The Function is simply described.

In the Function section,the function of the command is described,but the description is very simple. For example:

power off

2. The Parameters are described simply and the customers are doubtfulabout the contents in the Value.

3. The User Guidelines are lack of some important information, so they are not instructive.

Description

After optimization

1.The template for the Command Reference is optimized, and the Function is enhanced.The detailed function of the command is described. In addition, the scenario where the command is used andthe result after the command is executed are also described. For example:

2.The Parameters are described in detail.The parameters are described in detail, and such contents as the principles and type of

the parameters are also described.

3.The User Guidelines are improved.

The information related to the command is described in detail, including the related concepts, specifications, andprecautions of the command. This makes the Command Reference more instructive. For example:

Usage Guidelines

How to obtain the documentation :Documentation CD-ROM: http://support.huawei.com/

The set battery group power-off voltage must meet that: DC over-voltage - 1 V > even charging voltage > float chargingvoltage + 2 V and DC under-voltage > load power-off voltage > battery power-off voltage.

power off

FunctionThis command is used to set the power-off parameters for a load or a battery group. When the mains powers off, thesystem adopts the battery to supply power. When the load power-off is permitted and the load voltage reaches the loadpower-off voltage, the system reserves the 10 A output branch and disconnects the 50 A, 20 A output branchesautomatically. When the battery group power-off is permitted and the battery voltage reaches the battery power-offvoltage, the system automatically disconnects the connection between the battery and all loads. To set the power-offfunction for the load and the battery group to ensure that the device can work normally in the case of the mainsdisconnection, run the command. After that, all parameters take effect immediately.

All the matched traffic streams are deleted when the specified traffic stream is deleted.Each xDSL port supports up to 8 PVCs.Each service board supports up to 256 PVCs.The service virtual port cannot be deleted under the following conditions:

O The port is encapsulated as PPPoA, IPoA or as Auto.

O The port is added to the BTV user.

O The port is bound with the IP address or the MAC address.

O The port is configured with the static MAC address.

When you create the access traffic stream in the xDSL and ATM modes and if you do not specify the VPI and VCI, the system willallocate a VPI and VCI automatically. The initial value of the VPI is 0 and that of the VCI is 32.

When the service virtual port needs to carry multiple services:

O If the multiple services are differentiated based on the service encapsulation type, you need to input the service encapsulation type onthe user side.

O If the multiple services are differentiated based on the VLAN ID on the user side, you need to input the VLAN ID on the user side.

O If the multiple services are differentiated based on the user side priority on the user side, you need to input the user side priority.

Each physical port has up to one autosense traffic stream and it cannot exist with the common traffic stream at the same time.
