Telecom Network Management
Legacy Networks:
Circuit Switch Based
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:
1. Alarms are analyzed and Faults are are fixedimmediately
2. Trunks are not congested and Traffic isefficiently routed via:
a) Traffic Controls
b) Alternate Routing
1 & 2 produce Higher Call Completion
Rates resulting in Higher Revenue

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
