File Interface (PM) M2000 collects all PM information from

NEs, and saves the data into database.

M2000 acts as a FTP server and NMS

gets these files on schedule

Flexible statistics and displaying of

performance results: for clear statisticsanalysis

Generating alarms based on set

performance thresholds: for notifying

users of the current network operation Providing data viewing templates for

performance measurement data: for

viewing the performance data with the

conditions in the templates. Monitoring the NE status in real time: the

monitoring results are displayed in the

form of chart/tabulation or data for a clear

monitoring of the NE operation.

SNMP trapswith filter

M2000 receives fault events from NEs, and

saves the data into database.

At the same time, the SNMP traps are sent

to NMS.

NMS can query alarms though SNMP set

operation.

Alarm correlation analysis: for decreasing

alarms and increasing fault clearing

efficiency

Alarm severity redefinition

Real-time alarm display and filter: for

focusing on the alarms users are

concerned, and for tracing and locating

alarms.

Alarm remote notification: for the

maintenance personnel to know alarms in

real time through short messages.

Equipment panel: for displaying the alarms

and status of each board,

query alarm(SNMP set)

PROPOSED SOLUTION FOR OMCR:

Based on the following standard table for management capacity :

250 equivalent NEs8 CPU HP rx7640




Management CapacityServer Hardware

At circle level, two individual EMS servers will be provided. One for GERAN

Second for UTRAN At WCC (Core sites), OM data will be routed to M2000 server via PErouters, available on all core sites. At WRC (Remote BSC sites), OM data will be routed to the nearest WCClocation via BSNL provided transmission. FE to E1/STM1 converters will be

required.

Business Benefits of Centralized OSS Solution


23/25



1.Centralized Solution promotes easy and centralized management of Systems & resources.

2. Single database and simplified architecture allows easier system configuration.

3. Centralized Monitoring, Management and Reporting for distributed BSNL network, while stillallowing circle wise monitoring.

4. Unified Business Process and common Nomenclature throughout the organization.

5. Circle as well as zone based reports.

6. Optimization and better scalability of Hardware.

7. Improved & End to End tracking of faults in BSNL Network.

8. A centralized solution provides all the flexibility of a distributed solution, while also curtailingthe drawbacks.

9. Reduced time-to-repair , increased network uptime and revenue.
