Cross-generation access solutions for transporting legacy TDM traffic over Ethernet networks

RAD’s pseudowire TDM emulation solutions enable transparent delivery of TDM voice and data services over IP, Ethernet and MPLS-based networks. Our diverse mix of TDM pseudowire access gateways includes miniature SFP devices, small customer-located equipment and high-capacity aggregation units for central offices or points-of-presence (POPs). Featuring multi-standard pseudowire technologies, these TDM emulation gateways encapsulate the transmitted E1, T1, E3, or T3 streams in packets upon entering the network, then reconstruct the original bit stream and clock at the destination site. With more than 110,000 pseudowire links deployed worldwide, RAD’s pioneering legacy emulation solutions are typically used for backhaul of leased lines, telephony or mobile traffic over PSNs.

Benefits of using TDM emulation pseudowire solutions:

• Non-disruptive upgrade of legacy services to PSN networks
• Move to PSN backhaul reduces costs by simplifying network management, maintenance and operations
• Maintain TDM service quality and low latency with standards-based pseudowire capabilities, including CESoPSN, SAToP, TDMoIP®, as well as HDLCoPSN
• Ensure highly accurate synchronization under changing traffic network loads with high precision clock recovery
• Carrier-class availability with Ethernet ring protection and pseudowire redundancy schemes
