PSTN Transition Program


The years-long debate and discussion over the PSTN Transition has finally met a milestone with the release by the FCC of a Report and Order, Further Notice of Proposed Rule Making and other initiatives involving Numbering Data administration.

These are all useful things. However, the public policy debate is far from over. There is substantial opposition to various aspects of the Transition. News reports about the Transition have often been unclear and there are inaccuracies on the rationale and scope of why this has been taking place.

This program consists of a number of projects addressing the safety, integrity, and security of the all-IP network. Individual projects include:

  • PSTN Transition Study and Workshop: What are the real risks, opportunities, and policy issues in the transition to the all-IP network, as well as the imagined ones.
  • Software Engineering Database Transitions Study: Build a technology model for the number portability database and estimate the costs of a transition to an alternate provider. (complete)
  • Next Generation Caller Identification: Analyze current proposals, collect requirements, including deployment requirements, and develop technologies for solving the robocalling, swatting, vishing, and other reprehensible maladies affecting the legacy PSTN.
  • Rural Call Completion: How can the legacy network be monitored in order to improve rural call completion? Can we do better in the all-IP network, given that a number of the current problems occur due to SS7-SIP interworking issues?
  • Comprehendable Voice: How can we improve cognition of spoken language over the legacy, 3kHz, toll-quality network?
