  1. Numbering Policy in an Era of Convergence Hank Hultquist SBC November 4, 2004

  2. Big Picture • Network evolution: • All IP • Non-geographic • Consumer expectations: • Portability • Mobility • Numbering policy: • Must accommodate consumer needs and network capabilities.

  3. The Coming “All-IP” Network • Service providers deploying IP networks to provide a host of services. • E.g., SBC has begun deployment of fiber-rich network to provide IP services including voice, Internet access, and video. • Will greatly enhance consumer control over call control. • Providers are also introducing IP products that will “cannibalize” traditional offerings, producing a continued utilization decline on POTS network. • E.g., CallVantage, VoiceWing, etc.

  4. Changing Consumer Expectations Must Inform Numbering Policy • Numbering policy will not cater to distinctions of distance and geography that are increasingly irrelevant to the marketplace. • Regulatory reforms may accelerate marketplace changes. • Area codes will become geographically meaningless prefixes to consumers. • Most voice services will be mobile/nomadic. • Consumers will be able to unify their communications using fewer telephone numbers.

  5. So What Will Numbering Policy Look Like? • 7-digit dialing likely to wither away. • 10-digit “tipping point” will be reached. • Rate centers will be increasingly irrelevant to retail products. • Consumers will enjoy geographic portability. • Wireless and IP networks already provide. • POTS providers may have to provide in order to compete. • Telephone numbers will be identified with the person, not a physical point on the public network.

  6. Challenges & Opportunities • Managing the transition. • Technical experts should be tasked with identifying systems that can be adapted and those that may have to be replaced. • Making sure that resources are available for the services that consumers want. • Not a new challenge. • Ensuring that LNP does not “fall through the cracks.” • Roles and responsibilities may have to be refocused. • Unlocking numbering resources that are stranded today. • In longer term, barriers to use of stranded numbers may be lowered.
