6. Role of ITU-T and SG 13
Packet based infrastructure
IP Issues

• Application of IP technology into Telecom infra
  and
• specify Interworking between IP and Telecom
• service/network

• New architecture for full Packet based
  infrastructure (inc.Voice)
• Migration path from Circuit based to Packet
  based infra (inc. Interworking)
• Service and network capabilities for providing
  Packet based services
• New access technology, OAM and Performance study
  based on full Packet infra
