7.4 Alarm Management

Alarm management is part of the fault management in the OMS.
The fault management system includes a set of complete and intelligent functional
software, which can detect, isolate, and correct abnormal operations of the device
modules that are managed.
When a problem occurs in the MRS6100 system, exerting negative effects on the
service, the related modules generate alarms, which in turn are reported to the
operator by the alarm management module. Based on information obtained from
the alarm, the operator can take appropriate measures to solve the problem.

7.4.1 Architecture

The alarm system mainly consists of the fault detection subsystem and alarm
generation subsystem.
I. Fault detection subsystem
It monitors the running status of devices through various ways such as hardware
detection and software detection, and reports fault information in time.
Hardware detection is implemented by each board, and its contents include:
Operating status of this board (normal/abnormal; active/standby)
Channel fault
Online/offline
The operator can find logical errors through software detection that cannot be
detected through hardware detection, and its contents mainly include:
Self-loop test to board
CRC check
Memory check
Data consistency check
II. Alarm generation subsystem
The subsystem collects fault information and handles it, and then generates
detailed alarm information in various tables accordingly to inform the maintenance
engineers.
As shown in Figure 7-1, the alarm generation subsystem includes BAM software
module, Exchange module, device modules, alarm server (alarm application
module, alarm processing module and DB), alarm GUI, MML client and alarm box.
