• 14. BT' s original 21CN target architecture
• 15. BT has altered its voice strategy
• 16. BT' s focus is changing from MSANs to VoBB- based services
• 17. Voice on BT' s FTTx will eventually move over to SIP-based VoBB architecture
• 18. KPN' s original FTTC target architecture

• 29. Alternative fixed operators have a different set of priorities for NGN
• 30. The main options for cablecos are to migrate to VoBB or to outsource PSTN management
