LoopStar® 700 Circuit Emulation Technology Extends TDM Services Over Packet Networks

Traditional voice and private leased-line traffic continues to provide significant revenues for metro service providers, while at the same time, packet-based traffic is growing exponentially. This incongruity ultimately requires metro networks to determine the most cost-effective and strategic way to serve two masters: the traditional time-division multiplex (TDM) world, or the emerging packet world that represents the revenue future. | Traditional voice and private leased-line traffic continues to provide significant revenues for metro service providers while at the same time packet-based traffic is growing exponentially. This incongruity ultimately requires metro networks to determine the most cost-effective and strategic way to serve two masters the traditional time-division multiplex TDM world or the emerging packet world that represents the revenue future. In many cases the right solution is the one that extends the patented circuit-over-IP technology value of existing TDM services while optimizing the network for new revenues from packet services. It is the solution that supports a complete array of new and existing services across a unified easy-to-manage infrastructure. And in today s lean economy the right solution is the one that offers very low cost of entry yet scales gracefully in services and bandwidth whenever the business case warrants. APPLICATION NOTE Carrier-class Voice and Private Line TDM Services Over a Packet Infrastructure ADC responded to these market requirements by providing a solution that allows packet-based networks to carry both Ethernet and TDM traffic. Our solution bridges the diverse requirements between TDM traffic with its requirements for timing and synchronization and packet networking which tolerates all manner of delay inconsistency and impairment. The LoopStar 700 product suite uses breakthrough circuit emulation technology to extend carrier-class TDM services over today s packet networks. The LoopStar 700 delivers traditional T1 E1 or J1 circuit-based voice data video services over Ethernet IP with the same no compromise quality and robustness as a circuit delivered in native TDM over SONET SDH. Using this cost-effective device at the carrier edge one efficient Ethernet IP network can carry a full range of services to customer locations such as voice trunks from private branch exchange PBX systems and Frame Relay leased lines alongside Ethernet traffic. .
