As IP-enabled applications and devices have multiplied, service providers are transforming their TDM networks to IP and starting to migrate customers off their PSTN (and ISDN) networks in order to offer differentiated, competitive IP-based services. They also want to reduce opex. Ovum outlines why PSTN migration will become an urgent issue over the next five years.


  • PSTN shutdown will take decades. Some service providers have no plans to do so at all, and some will do so incrementally over time. Migration of PSTN services and customers will happen faster than network shutdowns, but only just. On an aggregate global basis, PSTN migration is still in relatively early stages.
  • PSTN migration brings significant benefits, especially when done in a timely, accurate fashion and when combined with NGA upgrades. The benefits can be higher when implemented at the time of next-generation access network upgrades to create a single all-IP network.
  • PSTN migration will become an urgent issue very soon because vendors are planning to discontinue PSTN-related product lines and support. The aging workforce with knowledge of PSTN infrastructure will add to the urgency.
  • Outlines and discusses the benefits and challenges of PSTN migration
  • Highlights the urgency for service providers to develop a plan for migration
