Agenda
NGNDrivers and Approaches
Migration and implementation best practicesWhat
happens to the legacy systems

NGN DriversDrivers for NGN platform regarding
revenue and costs.
Increase in traffic (e.g. through dial-in not
materialized)
Competition
Generating new revenue through VoIP and services
that integrate voice/data
Drivers for uptake of NGN technology
Potential for boosting efficiency
?

Long-term operability of existing voice
platform

NGN Opportunities and threatsThe right timing
of NGN adoption is of fundamentalstrategic
importance.

• Opportunities
• New services that integrate voice/data
• More flexible design of new voice-based features
• Location optimization
• More efficient line utilization
• Lower energy consumption
• Reduced space requirements
• Cost optimization

• Threats
• NGN integrated within a complex technical
  environment
• Reliability of components
• Higher network concentration
• Running cost savings alone do not justify an NGN
• Technologies run in parallel for several years
• Standardization of hardware and software
  components not completed in certain areas
