Local Break Out Network Design

   • Local Break Out (LBO) is the only option available

         - All customers must have dial tone delivered to the customer environment

             • Can be “any carrier”

                 • PSTN through TDM Services (CTL or Other Carriers)
                 • SIP Trunk from CenturyLink (CTL or Other Carriers)

         - All calls will need to be processed at the customer router for delivery to the
             user.

         - Need persistent connectivity from customer environment to both HCS
             Platforms (call control traffic, VM)

                 • Either through CTL MPLS Private Port (Ethernet)
                 • Other Carrier Network (the customer must provide a router at each data HCS data center as

                     the meet point between the carrier and CTL requires Ethernet connectivity)
