目次

Our study into TDM-to-IP migration indicates that some European operators have adopted a progressive approach and that their transition programmes are well underway.

The PSTN is beginning to look unsustainable for many incumbent fixed operators. Most operators have plans for decommissioning legacy assets, and the PSTN is likely to feature significantly. But is the cost of transforming the network worth the returns it could deliver on a service that fewer and fewer people actually want? In this Report, we closely examine the subject of migrating voice services onto an IP platform and switching off the PSTN.

This Report provides:

  • details of operators' plans for decommissioning legacy assets
  • an outline of the options for replacing TDM networks
  • a survey of operator attitudes towards NGN transformation for fixed voice
  • a detailed examination of the likely costs and benefits for operators
  • a multi-criteria analysis of non-quantifiable factors influencing NGN decisions.

ABOUT THE AUTHORS

Richard Linton (Consultant) has more than twenty years' experience in the telecoms industry, and has worked as a consultant with Analysys Mason for more than 8 years. He specialises in technical and commercial work for operators in both the fixed and mobile areas. In the fixed sector, he has worked overseas on many projects for a number of incumbent fixed-line operators.He holds a first class honours degree in Physics and a PhD in Engineering.

Rupert Wood (Principal Analyst) is the lead analyst for Analysys Mason's Fixed Networks research programme. His primary areas of specialisation include next-generation networks, long-term industry strategy and forecasting the dynamics of convergence and substitution across fixed and mobile platforms.Rupert has a PhD from the University of Cambridge, where he was a Lecturer before joining Analysys Mason.
