Consequences:

•No offering of VoIP/ATM services

Only upgrade in voice sector

Build one new universal network (IP or ATM)

Consequences:• Implement all existing services again in IP or ATM

• Very long time to market (before system is stable)

• Interworking with legacy tremendously costly

• High investment necessary

Broadband is a real necessity?


It’s the basis for converged services !– parallel access to PSTN and data networks & interworking– integrated authentication, billing, OAM

Integrated AccessWhy?

It’s flexible!– change services without the need to change the access– choice between circuit switched and/or packet based services

It’s economical!– migration of existing infrastructure– plug and play provisioning– all-in-one system


Residential users:Today’s situation (single analog access line)

Mandatory Requirement to get considered


The Future

VoIP Enabled Branch Offices

VoIP Teleworkers

Encouraging use of new High Speed Access Technologies

Changing Business Structures & Organisational Interactions


Conclusion

VoIP is not a goal in its own right -

Convergence is the customer need

Customer demands are not uniform address the solution carefully

Customer Acceptance is growing albeit slowly

It is The Way Forward
