Network Management area of interest is the Central

Offices and the Transport Network linking them

Major Functions:

Alarms Monitoring and Correlation for Switching and

Transmission

Traffic Management via monitoring and control of traffic in

inter-switch trunks

Telecom Network Management

Network is healthy if:

NGN Management Issues

Traffic Monitoring and Control is almost automatic

Resilience of the NGN reduced the effects of NetworkElements failure

Network Management focus is shifted to Customersand their SLAs rather than Network Elements (COsand Transmission)

The new Operation Support Systems (OSS) must havedata on customers and will prioritize delivery ofservices to satisfy the Telcos commitments in SLAs

Call completion is almost a given

QoS based on meeting the SLA conditions becomesthe new yard stick for successful network management

NGN Management

Telemanagement Forum developed a newBusiness Process Framework based on the

enhanced Telecom Operations Map (eTOM) eTOM is based on NGOSS (New Generation

Operations System and Software) the industryagreed upon business solution framework forNGN OSS/BSS

Goal is rapid development of flexible, low cost ofownership solutions to meet the business needs ofthe Internet enabled economy

Conclusions

Telcos need to upgrade their OSS/BSS

following the latest industry standards in order to

meet the Quality of Service requirements

The transition has to be efficient, with minimal

cost in order to stay competitive in the new

commodity market conditions

Considerable investments may be required to

meet the new services. Prudent investing is

necessary to maximize its return
