9. … OSS through Java Initiative (OSS/J) TMF : NGOSSTM
open, standard set of JavaTM API’s
OSS Common, Service Activation, Quality of Service, Trouble Ticket, Billing, Inventory API’s
TMF : NGOSSTM
New Generation Operations Systems & Software
Based on contract specifications and shared information
OSS integration with components supporting contracts
Common communication infrastructure : messaging bus
Commercial-Off-The-Shelf Software : plug & play
A lot of progress, but still lacking the Standard
Too many, too little, too late : burden on the industry

10. Integrated Management
Scope : TMF e-TOM (Telecom Operations Map)
Horizontal integration : end to end
Customer Operations Processes
: Fulfilment, Assurance, Billing
Multiple network elements
: SoftSwitches, Access GW, Trunking GW, Wireless GW, Home GW, Application Servers …
Multiple technologies : Voice & data, Circuit & packet …
New applications/services
Next Gen. Wireless Service : 2.5G, 3G (CDMA-2000, W-CDMA)
Mobile Internet, Wireless LAN
Broadband internet access : xDSL, Cable Modem, FTTx
Location based services, Multi-media applications
Multiple protocols : TL-1, CMIP, SNMP, CORBA, XML …

11. … Vertical integration : top to bottom Management of user terminals
Business management : CRM, Supplier/Partner RM, Billing
Service management and Operations : QoS, SLA
Resource Management and Operations
Correlation of network events to customer impacts
Management of user terminals
Home Networking with intelligent gateways
Mobile devices : PDA’s, Handsets …
Remote Management
Fault Diagnostics / Localization, Loop Management
Auto Configuration, Remote Download
Efficiency : technical as well as economical
Financial constraint on the Telecom industry
