  1. The Next Step for Next Generation Technology: Interconnecting Managed Packet Networks to Preserve Voice Service Quality and Competition Joe Gillan joegillan@earthlink.net June 2008

  2. ILEC Network Initial Deployment: Managed-Packet Islands Cable Managed-Packet Network CLEC Managed-Packet Network MG MG ILEC Network Wireless Managed-Packet Network Managed-Packet (MP) Networks operate as isolated islands today, with QoS assured within each network. However, when customers served by one network need to communicate with the customers of the ILEC, the carriers exchange voice traffic in legacy (TDM) form. MG – Media Gateway (converts MP to TDM) MG

  3. Incumbent Managed-Packet Network Competitor Managed-Packet Network End Office TDM Media Gateway Media Gateway Media Gateway Forcing Voice Traffic Exchange in Legacy Format is Artificial and Inefficient Where the ILEC has deployed a Managed-Packet Transport network, there is no technical reason for interconnection and traffic exchange to occur in TDM form.

  4. The Logical Next Step: Interconnection Between Managed-Packet Networks Incumbent Managed-Packet Network Competitor Managed-Packet Network End Office MP Media Gateway SBC/Router SBC/Router Unnecessary conversion to TDM can be avoided, with traffic exchanged between Managed-Packet Networks in packet form, with QoS established end-to-end.

  5. The Evolution of Managed-Packet Networks Incumbent Managed-Packet Network Competitor Managed-Packet Network Packet Switch MP Gateways / ATAs SBC/Router SBC/Router Over time, managed-packet technology will be deployed closer to the customer, and will eventually supplant TDM in most areas. The “last-stand” for TDM technology cannot be the high-density interconnection trunks between local networks.

  6. Managed-Packet Interconnection is Feasible • Among carriers without market power, some voluntary traffic exchange arrangements for voice are emerging, but primarily for interexchange traffic. • The greatest volume of traffic, however, is exchanged with the incumbent local telephone company. • The most important element in the development of managed-packet traffic exchange is the interconnection between incumbent and competitor managed-packet networks for the exchange of voice traffic.

  7. The Bottom Line • It is essential that regulators preserve existing obligations of carriers to interconnect their networks to exchange voice traffic regardless of the underlying technology.
